i love that the filters come to me to the house. but the filters dont fit as well as the store bought filters and the one in the master sitting room whistles all night when the fan comes on. Yep, I can wrap tape of something to stop it but that defeats the convenience of having the filters deliverd. Sorry, I am going to cancel my service.
I always had a difficult time finding the right size filter for our furnace. I saw this company and decided to try them. They are wonderful and I highly recommend them. You can set it up where they send your filters as often as you want and you receive them within two days. They are very good filters also. They deserve a "five" rating. .
I've purchased numerous filters for my furnace, I'm very pleased with them since I have allergies that require good filtration. I will continue to purchase these filters that add re Merv 13.
