Love the FilterQueen Defender Air Purifier

We have 2 Defenders in our house. Last year we bought our son a Defender for his house. This year we bought both our daughters a Defender for their homes. With all the allergies, the Defender has helped so very much. All 3 of our kids love theirs and were amazed at how much it helped them sleep without having problems breathing due to allergies. I recommend the FilterQueen Defender Air Purifier 100%!!

Very appreciated!

Love having this air filter! It feels fresher and cleaner in my house. Sometimes smoke from the wood boiler sneaks in and I feel there are chemicals that are being sprayed in the sky that are harmful. We are also surrounded by fields that are sprayed. Very thankful for fresh, clean air to breath at home!!
