I work at a Senior Assisted Living facility. I purchased four Defender Air Purifiers for the areas that have odor problems. I used the Defender and it cleared the odor in one day. One Defender replaces two air scrubbers that had not done the job!

“The First Responders continue to protect us while COVID-19 spreads 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 like family, so I have a responsibility to provide them with the safest possible environment at work. That’s why we run the FilterQueen Defender all day in our store. It constantly purifies the air for both my staff and our valued customers.”
