Great service—- really needed to filter out as much smoke residue as possible. It’s always a surprise to see how dirty the filters get— glad to have fresh ones!

Disappointed

I have installed Filterbuy filters for over a year. When I got a new order I noticed that they no longer had the light metal screen on one side. This provided strength and quality.
