I have been using Filter Buy furnace filters for 20 years. They are well made and priced right. I change them out every 30 days.

I just received these filters. New to me and need to assess how they trap dirt particles before I can truly rate them. They seem to be made very well and the cost is reasonable.

They fit okay. Unknown as to how they work. I guess I'll check how they work at the end of the month.
