Two concerns, the pleats were widely spread apart in the middle while others bunched together at the boarder, rendering them useless. The filter will give me 60% of its designed efficiency.
Only place I could find the 4 nominal thickness that was actually less than 4 as I needed from my air handler. Got a MERV 13 rating to help with indoor air quality for a new born and a toddler. I come back every 18 months and buy 6 more now!! Thanks for making regular maintenance easier, I actually change my dog hair clogged filters now
It's saved us a great deal of time & effort & each filter ladts us a lot longer than normal & its been very economical & has helped us better our air & our healths, which has made a difference. . . ty Filterbuy for always looking out for us
