Purity home air filters are the VERY BEST filters I have ever used in my furnace/AC system. They work even better than some $30.00 types I have purchased! I have been using them since 2005, when we built our new home; maybe even before that. (I SO wish Walmart would carry them.) The couple who run the business are SO nice to do business with, too! Sincerely, Jo Etta Johnson
