Review on Aprilaire Replacement Portable Allergen Purifier by Pete Norris

I have purchased pet and allergy filters several times over the last year, both from Revain and direct from Aprilaire, and they pet are never falling included as the product says. When they called them they apologized and said they were out of stock and they would send me one if they could which was a few months later. Although they ended up doing it the problem I had was they sell the $10 pet filter as an allergy with no pet filter which is a problem because how can I tell the filters are exactly the same and the only difference is catching the pet. Otherwise the filters work perfectly, but have to give 1 star. Deliberate theft of money.
