The media [Filter} set consists of 3 different media that address different contaminates in water.
The first media which is in the #1 housing, will address sediments. This could be sand, hair, dirt and large [20 micron or more] particles that will be captured in this housing.
The 2nd housing #2 media, consists of a mixture of a very special Activated Carbon in granular form, called GAC for short.
The #2 that contains the GAC is a proven option to remove certain chemicals, particularly organic chemicals, from water.
GAC filters also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor), chloramines or chlorine.
The GAC we use complies with NSF, EN, and AWWA standards for drinking water treatment,
are accredited by regulatory agencies like NSF in the USA and KIWA in the Netherlands, and also meet the requirements of the Food Chemicals Codex.
Coupled with the GAC we also add, KDF85 [KDF 85 Medium Removes or reduces iron and hydrogen sulfide from municipal or other water supplies.
Also controls scale, bacteria and algae]. KDF85 Process Media can remove up to 99% of water-soluble lead, mercury, nickel, chromium,
and other dissolved metals. All KDF Process Media forms are effective in controlling the buildup of bacteria, algae, fungi and scale, making them ideal for use in our GAC beds.
The #3 media is an Activated Carbon Block which attracts negatively charged contaminants- like chlorine, benzene and cancer-causing chemicals, and the block carbon provides the most effective filter. According to EPA (the Environmental Protection Agency in the United States) Activated Carbon is the only filter recommended to remove all 32 identified organic contaminants including THMs. The same is true for all 14 listed pesticides and 12 herbicides.
WARNING: Any of the above, please do not use with water that is microbiologically unsafe or of unknown quality with adequate disinfection before or after the system
