Filterbuy is Money first, Customer Satisfaction last, Quality next to last
My experience with FILTERBUY is similar to others who have reviewed this site. Their rigid 90-day return policy doesn't take into account that you may have bought in bulk and don't use all of the filters within 90 days. The filters I bought here were the right spec but they didn't fit quite right and an AC repairman confirmed that they were the wrong filter size. I didn't discover this within the first 90 days but Filterbuy won't even EXCHANGE the remaining (unused, unopened) filters for the correct ones. (I guess I wouldn't want 'em back either).
