Filtrete™ Premium Allergen & Ultrafine Particles + Odor Reduction filters come packed with True HEPA filtration* with an optional carbon layer designed to help defend against strong odors .
Designed to work with Idylis air purifiers, this Filtrete™ Room Air Purifier Filter offers True HEPA Filtration to capture 99.97% of all airborne particles. Dust, allergens, bacteria, viruses and more are particles of the past. Our top of the line filter even captures ultrafine particles 1000x smaller than the human eye can see. (Disclaimer: as small as 0.3 microns, from the air passing through the filter media. Initial efficiency value.)
