As we turn our minds from the summer busy-ness of our industry and finish off the vacation days we so deserved with our family & friends, I’m looking forward to the fall. Since I was a student, I’ve always looked forward to the fall season as a fresh perspective of the year ahead. As part of the NAFA board, I am excited to share with you that our 3-year strategic plan is finalized and we are ready to get to work accomplishing our Strategic Outcomes:
1. Increase Knowledge
2. Engage Members
3. Raise Awareness
4. Streamline Operations
Our voice needs to be stronger in the industry and we need to ensure that we are not only a resource for our members but we are seen as a source of expertise for our filtration end-users. Work is being done to make sure we are creating strong partnerships with our related industry associations as well as various Healthy Building certifications. In being the source and experts for air filtration, its important that our resources are up-todate, easy to read, and that our content is refreshed regularly. We are supporting our guidelines and technical committees with funds to accelerate the development and editing of our content. We are also looking for more opportunities to fund studies and research that continue to move the air filtration industry forward. If you have any ideas, please share with me.
COVID-19 has taught the world the importance of what we do. It’s forced end-users to be more educated than they ever were before. Now it’s our turn to make sure we keep educating the public with respect to COVID-19 and all other air filtration related factors and contaminants. While improved filtration reduces the risk and spread of infection of COVID-19, it also reduces the risk and spread of so many viruses and contaminants that affect a variety of industries. COVID-19 has definitely consumed the minds and hearts of so many over the past few years, it's important that we as NAFA members help our customers meet their goals for better air in whatever
industry they serve. First and foremost, we need to make sure we are protecting people but we also need to protect processes, products and equipment. In this magazine and further at our Annual Convention we will be learning about the importance of filtration in Indoor Grow Facilities. The conference will also have guidance on how to protect our indoor environments from Wildfire Smoke. Even though these talks are focused on particular contaminants and solutions, we can always take the learnings and transfer the knowledge to other filtration challenges.
Personally, I am most excited about our keynote address. Thom Singer will be talking about the importance of building, cultivating, and sustaining strong business relationships. In these crazy times, it’s the relationships I’ve made at NAFA and within the industry that have helped me and my business the most. I believe if I speak to any NAFA member, it’s the connections and strong relationships that have been the consistent and best benefit. I look forward to forging and fostering new and existing relationships in Coeur d’Alene. Please make sure to make this a priority for your fall plans. We can’t wait to see you all there.
Many thanks to the NAFA board and NAFA staff for their incredible work this summer. I can’t wait to see what the next three years brings. NAFA is in good hands with its upcoming board and team. They will continue to deliver our vision of the recognized leader in air filtration education and the global source for expertise, education and best practices in air filtration.
All my best,

The primary goal of indoor farming is to create a thriving environment for plants to grow healthy and strong. This goal is accomplished by giving everything the plant needs, including light and carbon dioxide (CO2) for photosynthesis, the right temperature and humidity for evapotranspiration, and water and nutrient delivery for healthy development. Providing a clean indoor plant environment is important too. Clearing the air of potentially harmful airborne constituents reduces the risk of plant disease and contamination and increases the quality and yield of saleable product to be sold by the grower.
Fan coil unit with filters Nadia Sabeh monitors an active grow bedMore than half of the plant’s biomass is exposed to the air. The top half of the plant is responsible for photosynthesis, evapotranspiration, and developing the parts of the plant that we consume and enjoy. For lettuce plants, those parts are the leaves. For berries, it’s the fruit. For cannabis, the flowers. When these parts are chewed on by insects, colonized by mold, or otherwise degraded by bad constituents in the air, indoor farmers lose product to sell or are forced to use pesticides to eliminate pests and pathogens, a practice they try to avoid. By filtering the air that is delivered to plants, we can clear the air of constituents that could potentially harm, contaminate, or degrade the quality of the plant parts farmers sell and we enjoy.
There are many air constituents that are potentially harmful to plants. These constituents can be classified as biotic, abiotic, particle, and gas. Biotic contaminants are those that originate from a biological source, including pests, pathogens, and pollen. Common pests include insects such as aphids and thrips. The airborne pathogens of greatest concern include botrytis (gray mold) and powdery mildew. Pollen is of particular concern to cannabis growers, who cultivate female plants. Pollen from nearby male plants will cause the female plants to abort flowering, resulting in lost product.
Abiotic (non-biological) contaminants include smoke, ash, dust, ethylene, and other gases that can block critical pathways, stifle growth, and reduce product quality. In the case of ash and dust, deposition of those particles on the saleable (consumable) plant parts reduces their quality.
Some plants, such as cannabis, also produce volatile organic compounds (VOCs) that have an odor. These odors are of particular concern for growers in urban locations, where neighbors may not appreciate the smells emitted from a nearby indoor cannabis operation.
Therefore, using air filtration technology to eliminate or reduce the concentration of particulates and gases is not only beneficial to the health and productivity of the plant, it’s also beneficial to the cannabis farmer who strives to be a good neighbor.

Many indoor growers practice the technique of avoidance. Basically, they avoid bringing in outside air to their indoor plant environment by using recirculating air conditioning systems. Although this strategy makes sense on the surface, if the interior air is contaminated, the problem will only exacerbate without having access to outside air to help dilute and replace the indoor air.
Elimination through air filtration is very effective at removing particulate matter, such as insects, pollen, dust, and mold spores. Using MERV 11 air filters in the HVAC system removes particles that are the size of mold spores and are effective against botrytis and powdery mildew. Viruses are of lesser concern to most indoor growers, unless they are operating a tissue culture lab or are concerned about human health (eg. COVID protection).
For these smallest of particles, HEPA filters are recommended.
UV-C radiation can be used to denature the proteins (DNA) of potential biological contaminants and has been shown to be effective against powdery mildew and botrytis. However, the long exposure time required for larger constituents, such as molds, and high airflow rates of air conditioners requires the installation of long lengths of multiple high-intensity UV-C lamps, a strategy that is both capital and energy intensive.
UV-V radiation can also be used to help eliminate odors. However, because a byproduct of its reaction with oxygen is ozone, its use is only recommended if installed on the exhaust airsteam leaving the building. Activated carbon filters are still considered the cannabis industry standard for odor removal and may be used in combination with UV filters to provide a double-punch against VOCs.
One of the primary advantages of growing plants indoors is that they are protected from the outdoors. That includes bad weather, animals that eat or trounce through the crop, as well as potential airborne contaminants. Using particle filters in the air conditioning equipment can remove most of the potentially harmful airborne constituents, including insects, mold spores, pollen, and ash. HEPA filters may be used in spaces where viruses are the constituent of concern. UV-C and UV-V radiation can be used to further eliminate biological contaminants and odors, respectively, but rarely are used in lieu of other air cleaning technologies such as particle filters and activated carbon.

All opportunities come from people. The leaders who understand how to get their team to make, grow and keep their business relationships find success in all economic situations. These “Uncommon Connections” can be cultivated and should be cherished. This presentation is an action-packed look at how to create business friendships, build trust, and create unlimited opportunities.
Growing crops indoors allows farmers to control many variables plants need to be productive and healthy, including the air they breathe and are exposed to. Keeping the air free and clear of pathogens and contaminants improves crop quality and yield, helps to ensure food safety, and provides a healthy working environment. In this presentation, Dr. Sabeh will review the application and necessity of various technologies and strategies commonly used in indoor agriculture to cultivate cannabis, leafy greens, and other crops to eliminate mold spores, VOCs and other airborne constituents.
The world of sales and marketing has fundamentally shifted (and continues to shift) to favor the wants and needs of our customers. The companies who embrace this reality are winning the attention and business over their competitors. In this session you will learn to adjust and adapt to the demands of today’s customers who are dramatically more informed, less patient and want more control of the sales process; and how to attract the attention of the right customers, to stand out from your competitors and become the trusted voice in the industry.

This best practice guideline establishes air filtration for the removal of particulate and gaseous contaminants for the protection of the Heating, Ventilating, and Air Conditioning (HVAC) equipment and components, as well as providing comfort and a healthy environment for the occupants and visitors of a residential property. The recommendations in this guideline are considered by the National Air Filtration Association (NAFA) to be “best practice” in contrast to “minimum standards” as put forth by other organizations. It will help guide qualified HVAC service technicians, manufacturers, contractors, and end users with the necessary information to make an informed decision when procuring, installing, and maintaining filtration products for the residential market.
This best practice guideline will address filtration products, installation, and maintenance practices for the various air handling systems that are used in the majority of residential properties. It will take into consideration health, comfort, equipment protection and tenant retention as factors involved in the filtration decisions.
For the purpose of this guideline, we will concentrate on single, multi-family, and low-rise multi-family residences. High rise apartments and condominiums are not specifically addressed in this guideline as the HVAC equipment in these buildings tend to be commercial in design and would follow closely the recommendations in NAFA’s Guideline for Commercial Office Spaces.
The quality of air in a residential building has a significant impact on human health and comfort. Poor indoor air quality (IAQ), as referenced in ASHRAE Std. 62.1-2019: “Ventilation for Acceptable Indoor Air Quality,” can lead to discomfort, ill health, and building related illness, making IAQ an important environmental health issue. The number of complaints related to IAQ has increased with the trend towards tighter sealed buildings, energy conservation, the growing use of synthetic materials, the increase in office and home equipment (photocopiers, laser printers, and computers), cleaning products, outdoor air pollution, and not the least, the increased awareness of the public to the symptoms and effects of poor IAQ. Contaminants that present specific problems in residential properties include: plant and animal allergens, gases and odors, bio aerosols (viruses, bacteria, fungal spores), and particulate, specifically below 2.5 micrometers in size (PM2.5). Exposure to a high concentration of fine particles in the PM2.5 range can cause short term health effects such as eye, nose, throat and lung irritation, coughing, sneezing, runny nose and shortness of breath. Research has shown that long term exposure to PM2.5 has been associated with increased rates of chronic bronchitis, asthma, heart disease, reduced lung function and increased mortality. People with breathing and heart problems, children, and the elderly are particularly at risk. PM2.5 can be attributed to outdoor sources, specifically the burning of fossil fuels, as well as from indoor activities, such as, smoking, cooking, burning candles, and functioning fireplaces.
Filtration is often expressed as a key component for a healthy indoor environment; however, the only mandatory reference to filtration performance is in ANSI/ASHRAE Standard 62.2-2019 “Ventilation for Acceptable Indoor Air Quality in Residential Buildings:” “Mechanical systems that supply air to an occupiable space through ductwork exceeding 10 feet in length and through a thermal conditioning component, except evaporative coolers, shall be provided with a filter having a Minimum Efficiency Reporting Value (MERV) 6 or better when tested in accordance with ANSI/ASHRAE Standard 52.2 2017 Method of Testing General Ventilation Air Cleaning Devices for Removal Efficiency by Particle Size, or a minimum particle size efficiency of 50% in the 3-10 micron range in accordance with AHRI Standard 680, Performance rating of Residential Air Filter Equipment.”
The minimum filtration level of MERV 6, as referenced in ASHRAE Standard 62.2, does little to address the removal of PM2.5 size particulate which is a key component of air quality evaluation in an occupied space. To improve IAQ in residential properties, and to meet NAFA’s minimum filtration recommendations, as detailed in this guideline, requires more than replacing the current filter with a higher MERV product. The goal needs to be system performance which will require a synergy of all the HVAC components. In addition to a quality filtration product, the ideal residential system should have a dedicated outside air source supplied directly to the air handler system, filter hardware that will eliminate the chance of air bypassing the filter system, sufficient filter system area and depth to accommodate newer filter technology, fans capable of overcoming the increase in resistance to higher efficient filters, and control features that allow the home occupant the ability to realistically evaluate the condition and service life of the filter based upon pressure differential and the quality of the air supplied to the occupied space. These technologies and concepts are currently available in commercial systems and could quite easily be made available to the residential market. The public demand for improved IAQ in residential properties is there and needs to be embraced by all facets of the HVAC industry.
The residential property of today is often more than just a space for living and more complex than properties of the past. People are spending more time indoors, as well as more time working from the home. Specialized mechanical equipment is required for servicing these situations and the unique activities associated with them. The following mechanical equipment are the most common types found in residential properties.
Forced air furnaces are permanently installed appliances that provide heated air through ductwork to interior spaces. The most common heat sources are natural gas, electricity, and heating fuel. A forced air furnace is equipped with a blower/fan that draws air into the heat exchanger through a filter and then distributes heated air through the ductwork to the interior spaces. Additional equipment can be added that enables a forced air furnace to humidify, dehumidify and cool the air. NAFA recommends a MERV 11 or better filter* for residential furnaces. A MERV 11 filtration system will provide an improved removal efficacy of the targeted PM2.5 particulate than less efficient traditional products.
In forced air systems the same duct work can be used for both heating and cooling. Split system central cooling is the most widely used forced air system. Condensing units are installed on a non-combustible pad outside the dwelling. UAC units are factorymade systems that normally include heat/cool coils, fan, motor, humidification, filtration, and ventilation components. NAFA recommends a MERV 11 or better filter* for residential UAC systems. A MERV 11 filtration system will provide an improved removal efficacy of the targeted PM2.5 particulate than less efficient traditional products.
Fan coil units are small unitary systems that provide a combination of heating or cooling to condition a space. The units can sometimes be supplied with outdoor air dampers for ventilation. In a residential space, fan coils are often used to supply conditioned air to the entire property. NAFA recommends a MERV 11 or better filter1 for residential fan coil systems. A MERV 11 filtration system will provide an improved removal efficacy of the targeted PM2.5 particulate than traditional products.
1. Increasing filter performance can possibly have an adverse effect on system operation as well as increasing energy consumption. Refer to the section “Monitoring of Airflow and Pressure Drop” for additional information and/or consult with a qualified NAFA Certified Air Filter Specialist (CAFS) or HVAC technician.

Heat pumps for residential applications are normally centrally ducted unitary or split systems. Heat is taken from one source and transferred to another. Heat pumps are capable of heating in the cooler months and cooling in the warmer months. NAFA recommends a MERV 11 or better filter1 for residential heat pump systems. A MERV 11 filtration system will provide an improved removal efficacy of the targeted PM2.5 particulate than traditional products.
filter for protection. A combination particulate and gas phase single filter or dual stage filter system would be necessary. Most residential HVAC systems can only accommodate low pressure drop filters which limits the selection for effective gas phase filters. It is best to contact a NAFA CAFS to help with the selection of the gas phase filtration system.
These units are often used for single room cooling applications and do not normally have a filter as a component of the system. If a filter is included it is generally a permanent washable filter. Follow the manufacturer’s recommended guidelines for filtration and maintenance.
Other forms of heating residential spaces such as radiant heat, hydronic (hot water baseboard), and steam radiant can provide comfortable and controlled heating spaces but do not allow for the introduction of outside air for ventilation, nor are they capable of filtering, humidifying, dehumidifying or cooling the air.
To improve air quality in residential spaces consider any of the following air cleaning technologies which can be deployed as stand-alone units.
Ultraviolet Germicidal Irradiation (UVGI) is an air purification system that is gaining popularity in the residential market. Successfully used for years in the commercial and health care industry, UV-C light effectively reduces the transmission of airborne germs, bacteria, mold, viruses, and fungi by disrupting the micro-organism’s ability to replicate. UVGI is effective as surface kill on a coil or airborne via an in-duct system. UV lamps are usually installed in the return duct or downstream of coils in the supply duct. For best results, use in combination with a particulate filter.
Gas Phase filtration addresses the need for removal of airborne molecular contaminants (odor/chemicals). This requires a different approach than particulate filtration in that gas phase filters are designed for the removal or elimination of molecular contaminants. Gas phase filters for residential applications might look similar to particulate filters but are quite different in design, specifically the treatment or type of media used in the filter. An example of a gas phase product is a carbon-impregnated filter. Ideally, a gas phase system would still require a particulate
Room Air Cleaners are self-contained filtration packages incorporating a single, or multi-stage filter system along with a blower/fan to draw in dirty air and disperse filtered air back into the space. Effectiveness of these units relies on the capacity in cubic feet per minute (CFM) of the fan/blower, the quality of the filtration media, and the integrity of the filter holding device. There are a myriad of products on the market making, in many cases, unsubstantiated performance claims. A buyer beware attitude needs to be taken by the consumer.
Electronic Air Cleaners/Electrostatic Precipitators (EAC) are packaged filter systems attached to the furnace duct work. In the first stage, or ionizing section, particles in the airstream are given an electrostatic charge. In the second stage the charged particles are removed from the airstream by oppositely charged collector plates. Electronic air cleaners can be very effective on fine particulate but are prone to the creation of ozone. “Ozone is harmful for health and exposure to ozone creates risk for a variety of symptoms and diseases associated with the respiratory tract” (Koran et al. 1989; Touloumi et al. 1997; Bell et al. 2004). EAC units require diligent maintenance of the ionizing wires and collector plates to maintain performance. EAC units cannot be tested by ANSI/ASHRAE Standard.52.2-2017 and therefore, do not have MERV data associated with performance. For these reasons, NAFA does not recommend the use of EAC units in residential applications.
“Evolving complexity and increasing operating costs demand that equipment and systems providing thermal comfort and beneficial IAQ be properly maintained to achieve energy efficiency and building owner’s reliability requirements.”
- ASHRAE 2019 handbook; HVAC Applications
Filtration in the majority of residential applications has not received a level of importance equal to the benefits associated with proper use. As filters increase in efficiency, the importance of the fit of the filter cannot be understated. The recommended MERV 11 filter in this document will not provide MERV 11 system performance if the tracking or holding apparatus does not securely
Room Air Conditioners, Mini-split System/ Ductless Split System and Room Air Conditioners/Mini-split System/ Ductless Split Systemseal the filter in place effectively preventing unfiltered air to bypass the filter. Maintaining the integrity of the filter system is vital for the efficacy of the HVAC system and imperative for air filtration performance, because unfiltered air by-pass is a key contributor to poor IAQ. After each filter installation, the system, including filter frames, fastening devices, caulking, and gaskets must be checked to ensure that there are no possible leaks or gaps in and around the filters. Any repairs must be made at this time. A positively-sealed filtration system will prevent unfiltered air bypass and maintain system integrity.
When changing or modifying the model or design of a filter system, consult the manufacturer’s specifications of the air handling system. Consideration must be given for size, fit, media area, airflow rate, and initial and final pressure drop of the new filter system. NAFA further recommends consulting with a mechanical engineer, or HVAC technician, prior to making any modifications to your HVAC system.
Good operating procedure should include a monthly inspection of filters, filter frames, fastening devices, caulking, gaskets and ductwork. Removing and replacing damaged or defective filters, gasket, and duct insulation will keep unfiltered air from bypassing
the filter system. As a rule of thumb, filters should be changed based on manufacturers’ recommendations, or minimally twice annually, at the beginning of the heating and cooling cycles. Filters often need to be changed more frequently due to outdoor air conditions and/or particulate loads generated in the occupied space. Operating the fan on a continuous basis can also increase the change frequency. Keeping the coils and blower free from dirt and debris by filtration will improve airflow, increase system efficiency, reduce electrical consumption, and maintain overall system integrity. In summary, good maintenance will keep the HVAC system in proper working order and will provide the building with air that is not only conditioned, but also cleaned with a reduction in contaminant levels.
As a supplement to manufacturers’ guidelines, see NAFA’s Installation, Operation and Maintenance of Air Filtration Systems Manual.
Particulate filters in an HVAC system increase the resistance to the flow of air, gradually reducing the volume of air supplied to the occupied space. This increase in resistance is referred to as “pressure drop” or “differential pressure.” A newly installed filter will have an initial pressure drop specific to that product. As the
Cont'd from previous page
filter loads with dirt, the pressure drop increases resulting a reduction in supply airflow. This pressure drop can be measured with a pressure sensing device such as a Magnehelic® gage or a digital electronic pressure drop indicator. Measuring the change in pressure drop can help monitor airflow and provide an indicator of filter life and suggested replacement (often recommended as twice initial pressure drop). When a filter reaches its recommended pressure drop reading it should be replaced. Leaving a filter in place after this point can reduce air volume, increase operational and energy costs, and could damage the HVAC system.
Most gas phase filters do not increase in pressure drop over their service cycle if they are installed downstream and protected by a particulate filter. Some particulate media when impregnated with sorbent will increase in pressure drop, however, it is not indicative of service life of the sorbent. Service life of a molecular filter is a function of types and concentration of contaminants, and filter design. It is important to note that as the media life decreases so does the efficiency of the molecular filter. Molecular filters are often recommended for change-out before sorbent is 100% spent and NAFA would recommend replacement on at least an annual basis.
Both particulate and molecular filters should be disposed of in accordance with all local, state and federal regulations.
This guideline identifies what NAFA considers as the “best practice” recommendation for filtration in residential properties. It looks at a system specific approach to improve indoor air quality and equipment protection in single, multi-family, and low-rise multi-family residential buildings. It raises awareness of the filter as one element in the HVAC system by emphasizing the importance of the filter hardware, proper installation, and good maintenance practices. It also issues a challenge to the HVAC industry to provide the best and latest technology in filtration and IAQ solutions.
The new Filtration for Technicians and Contractors Servicing the Residential HVAC Industry Guideline was published January 2022 by the Guidelines Committee. To see a full list of available guidelines, visit the NAFA website:

The Carmel Clay School District is a public school district located in Carmel, Indiana, serving Carmel and Clay Township. The district operates 11 elementary schools (grades K-5), three middle schools (grades 6–8) and one high school, with an overall enrollment of approximately 16,500 students, and over 2,400 staff members. Carmel Clay schools consists of the following facilities:
Carmel High School
Carmel Middle School Cherrytree Elementary Clay Middle School Collegewood Elementary
Creekside Middle School ESC Building Forestdale Elementary Mohawk Elementary Orchard Park Elementary
Filter Services of Indiana provides filters, service and supplies for many school corporations and industrial buildings throughout the state of Indiana. Carmel Clay schools has made a serious investment into their air quality. They have upgraded all final filters to MERV 15/14A Microshields, and all prefilters MERV 8HC. All locations with only 2-inch filters with no final filters have been upgraded to MERV 13HC from MERV 8.
The following recommendations were presented by Filter Services of Indiana to provide better filtration and offer the best filter for their students and staff:
• Prefilters with a final filter: Multi-pleat XL8 MERV8 High Capacity with an initial pressure drop of .18 wg, and changed twice a year, and the Microshield MERV 15/14A with an initial pressure drop of .21wg changed every year.
• Prefilters with no final filter: Multi-Pleat Green Merv 13 High Capacity with an initial pressure drop of .29 and changed 3 times a year.
• Classroom Filters: All filters in the ceiling and in the heater units are MERV 8 Standard Capacity. These are changed twice a year during school breaks.
• V-B elts: Browning V-Belts, all belts are on an annual change with EMCOR.
Energy savings is a priority for Carmel Clay Schools. The school implemented a code that we, as a filter sales and service company, must adhere:
1. As educators, we are the role models for the leaders of tomorrow. When Carmel Clay Schools implements energy-savings measures and produces positive results in energy and financial savings, we are setting an example for our students. We are teaching them through our responsible actions that our impact on the Earth should be limited and can be done through a variety of actions.
2. Through a number of energy-savings efforts, from 4-day work weeks in the summer to recycling practices implemented throughout the district, Carmel Clay Schools is continuously working to limit its environmental footprint.
3. Fiscal responsibility balanced with providing quality education is a priority for Carmel Clay Schools. Green initiatives across the district have resulted in multi-million dollar savings for taxpayers.
Congratulations and well done to Carmel Clay School District, a 2021 NAFA Clean Air Award recipient and Filter Services of Indiana for their successful nomination.

How did you get your start in the filter industry?
After research of initially looking to partner with a local filter company for a filter delivery service, our eyes were opened to the much larger world of HVAC, filter quality, and their relationship to clean air initiatives. We initially took a very small trial with a local county to help their team out with the timely change of filters. The trial was successful and soon thereafter, there was a bid opportunity and Valor Enterprises of Florida was successful. From there, we have continued to grow.
What's the most challenging aspect running a filter company?
Kimberly has three adult sons (Alphonso, Edouard, and Jordan) and is a native Floridian. She was educated at Florida A&M University and her fields of expertise are operations management and training and development. Her hobbies are love of people, dance, and music. Kimberly loves anything outdoors, including fishing with her mother, Gertrude Bell, and swimming.
Distribution lines. It’s hard to get the filters to our warehouse in an economical way. In searching for the best product, we tend to find them in different states/regions. This increases our cost to get the filter from the provider to our warehouse. Because we work by contract, this has been challenging for us to absorb the additional cost when necessary. There has also previously been issues with receiving filters in particular sizes, but this gap has closed significantly.
What’s the best piece of business advice anyone ever gave you?
Invest in your employees.
“The diversity of my mentors are what I think made for the best lessons. Most of them demonstrated excellence in professionalism, fair treatment of employees, communication and ability to understand and relate to the messaging provided by your team. ”
If you don’t, someone else will - This resonated with me because no matter if I’m working for a large or a small company, or even for myself, there has to be an investment in the “employee”. Without good employees, you have nothing. So, invest the time, resources, and funding into them on every level you can. And when you’re done with the tangibles, give a little of yourself so they know who they are connected to as well as what you’re truly about.
What do you think is the biggest challenge the air filtration industry currently faces?
From my perspective, continuing to provide filters at a fair and consistent price will be a challenge. With the cost of everything going up, and carriers changing how they will charge for the load, the end cost to the purchaser has grown considerably and could continue to grow.
Did you have a business mentor and if so, who is/was it?
I love people and look for opportunity to grow with every interaction. As a result, I have had many mentors along the way. Men, women, black, white –The diversity of my mentors are what I think
made for the best lessons. Most of them demonstrated excellence in professionalism, fair treatment of employees, communication and ability to understand and relate to the messaging provided by your team. I’ve incorporated their lessons into all that I do. While there are many mentors who have supported me and demonstrated excellence, I’ll name just a few: Michael Johnson, President and CEO of J&A Group, Timothy Davis, Owner of 4TD Kids, and Kim Taylor, Human Resource Manager of Federal Express (Retired). A few of the many that I admire and who have collectively helped me to lay down a strong professional framework.
How has your company benefited from NAFA membership. While we are relatively new to NAFA, what we look forward to is aligning ourselves with others in the industry for further growth through connected resources. It is also a great opportunity for us to continue to learn about filters and the latest in the industry from the best there is.
Valor Enterprises of Florida began in 2019 as an idea for a company that could provide quality services that are flexible and trending for a reliable customer base. Through our research of the HVAC and filter industries, it became clear that there could be a need for larger companies and municipalities to have a third-party service to change filters on a regimented cycle of service. The era of COVID has taught us that the cleanliness of the air we are breathing in small spaces can be life changing. Our next steps are to continue our growth with other service contracts related to filter changing and to possibly diversify in the area of filter sales. We have recently been certified as a Minority Business and hope to connect with others who are in need of a Minority Certified partner. Keep your eyes on Valor Enterprises of Florida. We are making plans to be around for a while.

Partner Therapeutics develops and commercializes innovative oncology and infectious disease control therapies and solves urgent clinical needs. The health of the HVAC system at its Washington location was in critical condition since cottonwood seeds were clogging its chiller’s condenser fins and coils, blocking critical airflow.
Partner Therapeutics’ Lynnwood, Washington facility is located in an area where trees and flora are tough on HVAC systems, where debris can damage coils and other internal components. As a result, the company’s maintenance team spent 12-16 hours every spring hand-picking and cleaning cottonwood seeds, leaves, pine cones and other contaminants from their three EA water chillers. All three units had to be shut down during cleaning, impacting the entire business.
• PreVent saves you money, on average lowering HVAC repair costs by 30% and cutting HVAC maintenance costs by up to 2/3s.
• It protects your equipment, stopping airborne debris, protecting the fill material and coils inside.
• It is customized to fit on the outside of any air intake, including special shapes and cutouts.
• It improves equipment performance, helping interior, high-efficiency air filters last longer and HVAC systems work better.
• It is easy to install using Permatron’s secure and patented MagnaMount® earth magnet fasteners, with no drilling required.
With the PreVent system providing cottonwood screen relief, the pulse of business at Partner Therapeutics couldn’t be stronger. Because they fit on the outside of a unit, the maintenance team now spends minutes brushing off PreVent filters instead of days. In addition, productivity has increased since seasonal downtime has been eliminated.
Control costs and airborne debris with the PreVent system. To add up your savings, visit permatron.com/calculator
A cottonwood screen was needed—stat. So they contacted the local Permatron distributor, Trane Supply, and spoke to Account Manager Randy Aker. Mr. Akers explained why PreVent is the #1 prefilter. He spoke about the advantages of the PreVent system, its high-quality construction and its many success stories.
Partner Therapeutics immediately ordered custom-made PreVent screens for all three chillers. They loved how:
PERMATRON: THE #1 SOURCE FOR COTTONWOOD SCREENS Are your customers tired of wasting time manually picking airborne debris from their chillers? Ready to eliminate unnecessary and expensive downtime? Looking for the gold standard in cottonwood screens? Install the PreVent system today.
