How the Defender works
360° Air Intake
The lower half of the Defender pulls air in from every angle, no matter which way the machine is facing.
VOC & Odor Capture
Air filters through the Enviropure Activated Charcoal Wrap, capturing numerous types of harmful VOCs and unwanted odors from the room.
Air filters through the better-than-HEPA Medi-Filter Cartridge, capturing harmful particles down to 0.1 micron in size.
360° of Purified Air
The Defender circulates clean air back into the room from the top half of the machine.
HEPA is the industry standard (99.97% at 0.3 micron). Our filters have been independently tested to remove 99.99% of particles down to 0.1 micron in size.
How small is 0.1 micron?
Millions of satisfied customers worldwide have trusted FilterQueen for nearly 100 years.
We offer a LIFETIME perpetual warranty for the Defender Air Purifier. Purchase and replace your Medi-Filter Cartridge each year and enjoy a lifetime of clean, purified air.
Over 90 Years In Business
In the last few years, other companies have tried to take advantage of the urgency to protect the indoor air. Healthy indoor air quality has been our way of life since 1928.
The Defender removes 99.99% of harmful airborne particles that standard HEPA air filters leave behind.

"I can't imagine why anyone wouldn't want to have a Defender in their business."
— Walter, Restaurant Owner
The Defender moves easily from room to room, providing a healthier work environment.
Medical & Dental Offices
Rather than just relying on the building's HVAC system capacity, the CDC recommends using a portable HEPA air filtration unit for dental procedures and in airborne infection isolation rooms.
Restaurants & Bars
Polluted air is pulled in from all sides through both filters. Secure Seal Technology ensures that only pure, clean air returns to the room.
