What is a HEPA (High Efficiency Particulate Air) Air Filter?

HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke.

Millions of airborne pollutants are carried through the return air ducts of the heating/cooling system. The Air Purifier has been designed to be installed on the return air duct. A portion of this return air is by-passed through an opening on the back of the unit and passes through a 5-stage filtration system.

The air passes through a pleated Carbon Pre-filter which removes lint and large particles to extend the life of the HEPA filter.

Smaller particles then pass through a long-life, 99.97% HEPA (High Efficiency Particulate Air) Media Filter which captures particles 0.3 micron (1/84,000 of an inch) and larger.

The Photo Catalytic Oxidation (PCO) Filter is a Quartz media coated with nanoparticles of Titanium Dioxide (TiO2). The combined action of the UVC light and the TiO2 decomposes organic materials into basic molecules such as H2O and CO2 and reduces odors and VOC’s as a result.

A Carbon/ Potassium Permanganate Final Filter further reduces VOC’s and light gases.

Clean air is discharged back into the return air duct.
