I have used Filterbuy for several years and they continue to be a great buy for the truly good performance. I prefer the MERV 13 for filtering out my pets and keeping microbes in check.

I called to get a little advice and I must say they are so helpful and professional. They have a good price and ship very fast. I intend to shop here as long as I need filters.

I have used these filters for more than a year now and have been very happy with their performance. The cost is great when purchasing in quantities. With the Canadian smoke I feel my indoor air is cleaner.
