Filterqueen Defender
by W.C.
(USA)
Filterqueen has a very high quality product with it's defender model. Comparing it's price with others makes it seem very expensive also. However once you begin to understand what you're paying for, it's price seems cheaper and cheaper.
It can clean large rooms in under an hour and, just to prove it, you can feel the air movement it creates. IT ACTUALLY COOLS THE ROOM TO A NOTICEABLE DIFFERENCE COMPARED TO THE REST OF THE LIVING SPACE.
When you walk into the room once it has done it's work, the air really feels lighter, it's quite an experience knowing your unit is actually doing it's job, rather than just taking electricity.
It cleans down to the tiniest micron (i can't remember exactly) but they use this company's products in hospitals around the US, in rooms where air quality counts.
I have had my Defender for over five years now, I change it's filters regularly, and maintain it the best I can. It has lost some of it's original power, but it will still clean my entire main floor to a noticeable difference in about one hour from it's central position in my dining room.
I'd say in five year's time, the unit has gone down to about 90% of it's original power, judging from the noise and velocity at which it moves the air.
It comes with a complete money back guarantee, and you will never want your money back.
If you care about your air, and don't want to constantly throw away junk air purifiers, then get a Filterqueen Defender.
