CAMCLEANER CASE STUDY

NO.1 EUSTON SQUARE, LONDON – AIR QUALITY CASE STUDY THIS CASE STUDY LOOKS AT THE AIR QUALITY BEING EXPERIENCED ON A DAILY BASIS IN LONDON BY PEOPLE WORKING AND TRAVELLING ABOUT LONDON. It looks at how a combination of a standalone CamCleaner City air purifier, effective air filtration and a well sealed building envelope can deliver clean, healthy, Indoor Air Quality. In general terms the main health hazard comes from exposure to traffic pollution. Fine combustion particles and gases in a toxic mix that can be inhaled by people and are classed as a Group1 (highest level) carcinogen by the World Health Organisation. No:1 Euston Square, London is close to Euston station it is good for business and transport links of all types. Unfortunately transport such as trains buses and taxis produce this air pollution. There are other outside sources such as the much publicised recent southern UK air pollution incident involving desert dust and also volcanic events causing disruption to air transport because of airborne particles. Clearly these fine particles can sometimes travel in concentrated plumes over long distances and stay airborne almost indefinitely. This also applies to traffic air pollution particles and gases that can stay in the air and react producing chemical smog.

One this day the outdoor particle concentration level as can be seen by the red curve in Graph 1 was mainly in the range 80 - 90 million particles per m3 of air which is about over a twenty times higher concentration than the 3 - 5 million particles that would be expected in the air in a cleaner rural village location outside London. Clearly the air in our cities can no longer to assumed to be clean and healthy.

feels better to breathe and no longer has health issues. This air purifier is inconspicuous and effective. It runs quietly in the background and recirculates the clean purified air with almost silent running performance that consumes little energy. The green curve in Graph2 shows that close to the CamCleaner City particles are almost totally removed from the air. This unit also contains high efficiency molecular gas filtration that can remove NO2 and a range of indoor sourced air gas pollutants. This is a solution that delivers clean purified air at point of need and can be used in a residential or home office application as well as commercial settings. Camfil offers a structured and logical range of solutions to deliver Clean Healthy Indoor Air Quality including the City check IAQ test kit for indoor gases.
