FDA Class II Medical Device
The Defender is recognized by the FDA as a Class II Medical Device and is hospital tested.
Assembled in the USA
Our manufacturing and assembly plant is located in Ohio. We have been building FilterQueen products in the USA since 1928.
Unmatched Warranty
We offer a LIFETIME perpetual warranty for the Defender. Purchase and replace the Medi-Filter Cartridge each year and enjoy a lifetime of clean, purified air.
For schools
Clean the air in each classroom and help provide a better indoor environment for students, staff and teachers with the Defender Air Purifier.
Office areas
Rather than just relying on the building's HVAC system capacity, the CDC recommends using a portable HEPA air filtration unit to help protect your employees and guests.
Ozone-free
Caution should be used when selecting an air cleaner, as they may generate ozone and/or other potentially harmful chemical compounds.
No UV lights
Some types of electronic air cleaners use UV bulbs to improve the removal of pollutants. However, these devices can emit ozone and some that are designed to remove chemicals actually emit volatile chemicals into the air. – www.epa.gov

The "new normal" has been FilterQueen's way of life since 1928.
Helping create healthier indoor environments for over 90 years.

"Purchasing the Defenders for our school was a wise decision. Our staff and students feel more confident knowing that the air in the classrooms are being cleaned 24 hours a day. Thank you FilterQueen!"
Mrs. Keyra P., Dean, Arlington Christian Academy
"As a pulmonologist the science behind the Defender and its filtration capabilities are compelling. The fact that it has passed FDA clearance and is classified as a Class ll Medical Device confirms it's qualifications."
RB. MD Pulmonologist
"The safety and security of our employees continue to be our number one priority. While we have a ton of ideas for changes and enhancements to our offices, this is very much a work in progress and the Defenders are one product we believe will help clean the air and slow down the spread of COVID."
