It’s Aegis microbe shield not only eliminates the filter as a potential breeding ground for micro-organisms, when tested, they reduced airborne micro-organisms by up to 86.5% in a single pass through the filter!

leak guard seal

To ensure that all the air and pollutants go through your air filter and not around it, AIRTEVA Filters feature a patented Leak-Guard Seal. When your air conditioner or furnace turns on, the difference in pressure causes an airtight seal. No bypass means you're filtering 100% of the air. That means the harmful particles get trapped in the air filter, rather than in the lungs of you and your family.


Germ-Fighting Air Conditioning Filters

moldIt has been proven that mold and mildew are a common cause of allergies. As they grow, mold and mildew can release irritating spores into the air. You can control these spores from contaminating the air you breathe by using AIRTEVA Filters. BioSponge plus air conditioning filters utilize Aegis technology to eliminate the filter as a breeding ground for mold, fungi, bacteria and other common airborne contamination. Aegis treated filters, when tested, reduced airborne micro-organisms by up to 86.5% in a single pass!

You could think of the air filters surface as a layer of electrically charged swords. When micro-organism come in contact with the treated surface, the sword punctures the cell membrane and the electrical charge shocks the cell. Since nothing is transferred to the now dead micro-organisms, the antimicrobial doesn’t lose strength, the sword is ready for the next micro-organisms to contact it.

odor control

carbon filter

How do Activated Carbon filters remove odors?

Activated Carbon filters have the ability to capture gas molecules and hold them. The Activated Carbon filter surface is made up of millions of tiny pores, the gas and odors fall into these pores and are trapped there until the air filter is disposed.
A single Activated Carbon filter has a flattened surface area of a football field.

zeolite air filter

How do Zeolite air filters remove odors?

A three dimensional, micro-porous natural earth mineral, thermally bonded to polyester. Zeolite has the ability to remove Volatile Organic Compounds (V.O.C.) and gases. They are trapped in the void porous cavities in the filter. It is especially useful in removing Ammonia and ammonium compound odors such as pet odors and urine odors.
