The first purification stage starts with the Prescreening Filter.

Its main function is to capture large particles such as dust, pollen and skin flakes. Another feature of the pre-filter is to preserve and extend the life of the HEPA and Activated carbon filters.

By pre-filtering the larger molecules, it shields the HEPA filter from getting clogged.

The 2nd stage consists of a High Efficiency Particulate Air Filter commonly called a HEPA filter.

Originally developed by the Atomic Energy Commission, it removes 99.97% of particles down to 0.3 microns in size, almost 300 times smaller than the width of a human hair.

HEPA technology is currently the only type of air purification tool recommended by the U.S. Government’s Department of Homeland Security.

The 3rd filtration level includes an Activated Carbon Filter.

This particular filter capetures and neutralizes common chemicals, gases, odors and tobacco smoke with the highly absorbent micro-pores in its matrix.

The 4th filtration stage comprises An Advanced O.F.S. Filter, exclusive to the Enviro 68108.

The O.F.S. technology has proven to have broad spectrum antibacterial effects and can restrain growth and reproduction of Gram-positive and Gram-negative bacteria.

Test results prove that the O.F.S. filter can kill up to 97.7% of airborne bacteria in a room after 6 hours of operation.

This feature can be turned ON/OFF at anytime by using the remote control.

The 5th and final purification stage concludes with an Optional Dust Precipitator system. The Dust Precipitator system produce plasma flocks to knock down dust from the air and to dramatically precipitate certain harmful airborne particles, as small as .01 microns in size. This innovative technology is used extensively overseas in several industries and it is getting more attention all over the world.
