Ok, so who's got 'em? I just read a review of them and they don't seem to be the best for eliminating smoke, pet dander, allergens and what not. I'm wondering if there are any people out there that have one and swear by them. Do you feel that they eliminate allergen adequately? I suffer from sever hayfever and thought that this would help out in late summer. I also have 2 cats. Any help would be appreciated. Thanks.
