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 would prefer a removable reusable filter that could be washed and put back for use.
