The PUREFLOW^® advanced 4-Stage Filtration Process stops dust, dirt, and other harmful airborne contaminants on the spot.

The first stage features a high-efficiency layer with a MERV 13 rating, capable of stopping more than 90% of contaminants at sizes as small as 3 microns. Pollen, dust, and other common allergies don't stand a chance.

The second stage utilizes an activated carbon media layer to neutralize unpleasant odors.

The third stage once again involves the activated carbon media layer, but now, unpleasant odors are eliminated with a sodium bicarbonate treatment, otherwise known as baking soda.

The fourth stage of PUREFLOW’s powerful filtration process uses a layer of specialized antimicrobial fibers to inhibit the growth of mold, mildew, and other unhealthy bacteria.

Shut the Door on Indoor Air Pollution

Air pollution in most homes can be up to 5X higher than outside, and the adverse effects aren’t usually felt right away. Instead, they tend to happen slowly over an extended timeline, and before you know it, you or a loved one could be dealing with a serious illness. When you install a PUREFLOW^® HVAC air filter, you’re not just replacing the air conditioner filter; you’re upgrading to peace of mind and a living experience free of harmful airborne contaminants. It’s time to bring PUREFLOW^® Home Furnace Air Filters into your home and shut the door on indoor air pollution.
