Testimonials

"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."

Mold Allergies

"Over the past several months we have been working in partnership with our architect and other expert advisers on how we can have a safe environment for our employees upon their return. 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."
