For optimal performance, this AeraMax 9436902 PRO III and IV 2" hybrid air filter integrates two filter designs into one. The second half employs activated carbon to eliminate odor and volatile organic compounds from the air, while the other half is a real HEPA filter that has a 99.97% efficiency rate in capturing particles as fine as 0.3 micron. The entire filter has an antibacterial treatment that stops bacteria, fungi, and mildew from growing and gets rid of the stink that results. To keep your environment clean and pleasant, the filter traps everything from mold spores, viruses, bacteria, pet dander, and cigarette smoke to allergens like ragweed, pollen, and dust mites.
