Filtropur

Over paid for the product, but I was pretty happy with it. Does a good job of cleaning the air, and you can't even tell I own several Boxers when you walk in. Only problem is that their "warranty" covers only if you buy their filters. Sure, they clean it for free. But then you have to pay $120 for a filter I can make for $20. When I first purchased, they were about half that price. But since I refuse to get raped on the filter, it's not covered or cleaned, anymore. Purchased in 2014. Short of tearing the whole thing apart myself, and praying I don't break any of the cheaply made plastic parts, I'm not sure if it is even worth messing with. Do yourselves a favor and stay clear of these products. They aren't worth the hassle.
