Great add on to filter the air passing through!

Nice but lacking mounting features
This is a nice product, although at the end of the day it’s just a metal box with two holes, a door, and a filter slot. I bought two to use for my coffee roasting business and put them directly above my roasters with electrostatic filters to trap chaff and dust before the fan. My criticism of the product is that it has no mounting tabs, so I ended up having to get sheet metal screws and drill holes into the body of the filter box. It works but now my filter boxes have permanent holes, and I had to research, design, purchase, and implement my own mounting solution.

Love it. Need to use off brand filters
Like stated, it’s a nice filter holder. Built well. Down side is that ac infinity doesn’t sell a replacement filter that I know of. Had to measure out the one that came with the holder and get replacements from the hardware store.

Works well but severely overpriced for what it is
It's just a box with a filter inside, so I don't think this is really worth how much they're charging for it. But it works and there aren't really too many alternatives out there.
