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. .
The apartment community in which we live has old HVAC systems that require an odd sized filter. The filters they supply do not fit well and are a very low quality. I was able to obtain filters the correct size and of the highest filtering quality from Filter Buy helping us greatly with our allergies.
