Does anyone know how the pocket air filters found inside commercial air cleaners compare to the filtrete HVAC filters you can buy at the big box stores? I will be building my own air cleaner soon and I’d like to pick the best filters for the job. If I can design in only filters that can be found locally, I’d like to. Thanks!

alan i use the same filters that auto paint shops use. they have a tacky side that catches every thing…but they are a little pricey…

Design your enclosure so you have the Filtrete filters in “v” shaped pairs, kinda like

The idea behind the pocket filters is just to increase surface area.
If you can double or triple the number of standard filters it should be the same thing.

This filter is good to 1 micron and needs to be replaced annually. I don’t know how this compares to the others. FWIW

Have you tried going to manufacturer’s websites and looking for manuals? Often, you can get the specs that way, or barring that, call them and see if they’ll tell you the MERV rating of their filters.

Have your say...
