So far we're only on our first filter, but it is working great. We were getting a lot of problems with our old ones not filtering through the dust and pollen enough, But in the week we've had this one fitted we've noticed a difference already. They look very well made and arrived in good time. Thank you very much
We are a residential care facility with several furnace/ac's to maintain. Having the filters delivered every three months allows us to keep up with filter changes without having to store large amounts of filters. The filters are always of the highest quality. I would recommend Filter Buy for anyone that wants to keep the air we breathe clean.
