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 .
If you own an Idylis air purifier, you can now reap the benefits of a top of the line Filtrete™ Air Purifier Filter. This filter captures 99.97% of unwanted airborne particles, thanks to True HEPA filtration. It even captures particles 1000x smaller than you can see, so you can breathe cleaner, fresher air in your home. (Disclaimer: as small as 0.3 microns, from the air passing through the filter media. Initial efficiency value.)
