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

I put the new filter in the day after I got it. It seems to be doing a fantastic job of filtering the air in my home. I went from MERV 8 to MERV 13 and so far, I'm satisfied.
