The Filtrete 16 in. x 25 in. x 1 in. Ultra Allergen Reduction FPR 9 Air Filter attracts and captures large airborne allergens as well as microscopic airborne particles including pet dander and dust.
I have 2 cats, and i vaccum every day and in 90 days when i replace the filter with a new one, there it is: Cat Hair, this is the best, I also smoke, i know , bad,,,, but ppl that come over tell me they can not smell the cig. smoke, and there is no odors at all, like cooking odors etc. my place has less dust only need to dust every 60 days this is a great filter and worth the cost.
