I had difficulty when replacing my filters. The size required is very difficult to slide in without damaging some of the its' shape. These slide in easily as they are made a 1/8 to 1/4 inch less on width and thickness than actual slot. First time in 7 years with my (at the time brand new) furnace. Seriously very happy I found Filter Buy! I'll be purchasing more.
I purchased three filters 16X25X4 MERV 11. I removed a Honeywell filter from my furnace to be replaced by your filter. I compared the physical dimensions and noticed your filter is smaller and loosely fits in my furnace unlike the Honeywell that fits snugly. I would like an explanation prior to ordering additional filters. Thank you, Larry
The filters were way under par compared to the original. Couldn't use them as they were under sized all the way around. I really thought I had found a replacement. GC
