Great for people with allergies

My fiancé and I live in a basement, and as you all know basements get no ciruclation.  Period.  My fiancé has horrid allergies and hasn't been sleeping terribly well.  We also have two cats that we dearly love and don't want to part with, but if we didn't get the problem taken care of soon we would have to.

We found this at Walmart on rollback and decided to give it a try.  It was about 130 dollars on sale and we noticed results almost the first day.  Its been about a week since we've had it and we haven't had any problems with cleaning it or anything like that.  We are completely satisfied with our results. No filters required makes it really nice to keep up with it!
