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.

Office buildings

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 99.99% of pure, clean air returns to the room.

Schools

There is no doubt that the decision is difficult for parents to make in regard to sending their children back to school. You can help make their decision easier by cleaning the air in each classroom with the Defender Air Purifier.

Meets the following EPA guidelines:

Does not produce ozone

(ozone is harmful to the environment)

No UV light

(UV light is ineffective, costly and dangerous)

Effective filtration capability

(3x better-than-HEPA)

Provide fresh, clean air for your staff, patients or clients.

3x better-than-HEPA filtration

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.

Provides three times better-than-HEPA filtration to remove pollutants such as dust, dust mites, and mold spores.

Recommended filter change frequency:
Change once every year. For best results, change every 12 months for homes with pets or smokers.

Made with HEGA (High Efficiency Gas Absorption) material, which is highly effective at removing pollutants such as wildfire smoke, tobacco smoke, pet odors and lingering cooking odors.

Recommended filter change frequency:
Change every 3-6 months. For best results, change every 3 months for homes with pets or smokers.

Breathe easier with fresh, clean air.

"The Police and Firefighters continued to protect us while COVID-19 spread through our communities. I want to make sure that we are doing everything we can to protect them when they come to our store. My employees are family, so I have a responsibility to provide them with the safest possible environment when they return to work. That is why we run the FilterQueen Defender all day in our store. It constantly purifies the air for both us and our valued customers."
