How the Defender works

(1) – 360° Air Intake

The lower half of the Defender pulls air in from every angle, no matter which way the machine is facing.

(2) – VOC & Odor Capture

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

The Defender circulates clean air back into the room from the top half of the machine.

"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."
