About De-Ionization

How De-Ionization (DI) Works De-ionization, (commonly referred to as DI), is a common process for producing ultra pure water. The DI filter is filled with resin beads, some with a negative charge and some with a positive charge. When you test your water with a TDS meter (total dissolved solids), it gives you a number that tells you the sum of the different contaminates in your water. All of these contaminates are either negatively or positively charged, so when they pass through the DI filter they are attracted to the oppositely charged resin beads. Since the DI filter has both negatively and positively charged resin beads it is able to remove 99% of the contaminates in your water. Reverse Osmosis (RO) is capable of removing 95-97% of all contaminates, so when the remaining 3-5% is passed through a DI filter you are effectively removing 99.9% of the contaminates. This quality of water is comparable to distilled water and is excellent for use in reef aquariums and other application where distilled water is used. Is It Safe To Drink DI Water? DI water is 99% pure water, comparable to distilled water, so it is just as safe to drink as distilled water is. Due to the fact that it is so pure, a lot of people do not like the taste, so it’s potability (drink ability) comes down to your own personal opinion.
