How does the Defender work?

(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.

(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.

Meets EPA guidelines

Does not produce ozone

Ozone is harmful to the environment.

No UV lights

UV light is ineffective, costly and dangerous.

Effective filtration capability

Three times better than the HEPA standard.

Remove pollutants from the air.

The Defender removes 99.99% of many harmful airborne particles that standard HEPA air filters leave behind.
