They are just a little smaller than the ones I usually buy. Sometimes they don't stay on the supports inside the furnace making them a little crooked.

Much thinner than advertised size. 4" Media filter is at least half inch thinner than the Honeywell filter I ordered it to replace. Now have 4 useless filters

I replaced the MERV 8 with the MERV 11 since we now have a dog inside the house. The 11 is very effective for filtering out dog dander.
