Received filters very quickly. It seems to be working quite well now and I expect it to continue to give us good air. Really happy that you could deliver the proper sized filter as I was having a problem finding one until I found your website. Thanks. Jerry
Love this filters my wife has asthma and it has really helped also whats great is that it filters all the fine dust we dont have to dust our home that often and price wise you cant beat that thanks guys for your hard work
