Review on 🌬️ Enhanced Filtrete Allergen Defense with Uncompromised Airflow: Ultimate Air Quality Solution by Jeff Payne

I ordered a four pack 20x25x4 without knowing the actual depth. Shows 4" deep but the brackets say they are actually 4 3/8" deep which is what I want. Reading the reviews only added to the confusion. So see my photos. I checked the depth with a tape measure, which reads 4 5/16 inches. Also a picture confirms the MERV value of 11. I don't know why they insist on sticking with 20x25x4 when they could eliminate all this unnecessary confusion by simply changing the size to 20x25x5 , as made by other manufacturers. . Crazy! I've used Honeywell equivalents but they're a lot cheaper. 5 stars because of previous MERV 11 filters and because they fit perfectly. Their description gives the actual measurements, but some reviews said they were too snug or fit, and some said they were 4 inches deep. Hope this helps with the confusion.
