FLANDERS 10055.01202 20x20x1 FBG Furn Filter

I tend to avoid buying the more expensive filters. Not because I don't want to buy them It's just that I'm thrifty or my wife would say cheap. But these filters do the job the are supposed to do at a great price.

Lightweight, cheap and exactly what I ordered. It is not meant to hold back light dust such as flour. I use it to hold back the heavier particles and then back it up with a heavier filter, depending on whether it be smoke, fine particles or dust mites.

Good but thin. As expected for probe
