Exceeds My Expectations

My Filter Queen Defender is well designed and well-manufactured, and it blends in with my home furnishings better than many of its competitors. Before the Defender, my wife was suffering from allergies even though I have a whole house electronic air filter installed on my furnace that is manufactured by one of the leading HVAC companies. Since using the Defender her allergy symptoms have cleared up. The Defender being American made by an American company makes this purchase even better.

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%!!
