The HEPA (High Efficiency Particle Arresting) filter provides optimum filtration of pollen, dust, dander, and other respiratory irritants. HEPA removes a minimum of 99.97% of all particles greater than 0.3 microns in size. (A human hair is about 300 times too large to penetrate a HEPA.) The large activated granular carbon/zeolite canister with potassium iodide located beneath the HEPA filter is crucial for the effective removal of 4000 chemical substances and noxious odors in the air.
Zeolite is a natural cream-colored mineral that has the capability of capturing small molecules such as ammonia, formaldehyde and sulfides. Potassium Iodide is a catalyst that breaks down formaldehyde and related substances into a form more easily absorbed by the carbon/zeolite mixture. The enhanced absorption capacity traps other chemicals such as Volatile Organic Compounds (VOCs). They are all placed into one large cartridge that scrubs incoming air of all odors and chemicals.
