Air filters through the Enviropure Activated Charcoal Wrap, capturing numerous types of harmful VOCs and unwanted odors from the room.

(3) – Particle Capture

Air filters through the better-than-HEPA Medi-Filter Cartridge, capturing harmful particles down to 0.1 micron in size.

(4) - 360° of Purified Air

"I have the Defender air purifier and love it. Very easy to maintain and it does an excellent job. I am a heart patient and have COPD. Living the the California Central Valley, air quality here is very bad, especially with all the wildfires this season. The Defender has really helped a lot, and I would be lost without it."
