there pretty good
filters the house ok. if any of you live in the south though u know all about the red dust.....doesnt matter what MERV ratting filter u get if u have any red clay around and dogs the filters can only filter so much. still work 20 times better than a reg 1'' filter plus they last about 4-5 months with out having to change them. still recommended. and u get 2. cant beat the price for that. yeah there only merv 8 but there still good for a few months
