I and my HVAC service tech love these long lasting hard working furnace filers. I recently put in a new system (replaced the 23 year old furnace and A/C units) and have already obtained the correct size filter for it to be put into use in about 6 months time!

First time I ordered a Filtrete 20x25x4 Air Filter. I was excited to get this because it was a rated MERV 12. The problem is that this was too big even though my current filter (and all the other ones through the years) was a 20x25x4. It would not fit. I ended up tearing up the packaging around the filter to get it to fit. Terrible. When I put this on top of my other filter it was not same dimension.

easy to install. keeps air fresh. keeps dust down.

easy to order

I’m sure they were good filters but the wrong size. Sams club took them back no questions asked.

We ordered the set and it came in damaged. Got with customer service to get a replacement, and the replacement arrived damaged as well

Dented Box, Dented Filters. While they apparently shipped in a box from 3M, there was a nice crease in the box which ended up creasing BOTH fitlers. Given these filters are 4" in width that's pretty amazing.

my wife sheds like a donkey (and smells like one too) and we have to replace our filter often. This one works great and is priced well below some of the other brands.

Had to measure down on what our furnace requires, since this is technically not the brand of our HVAC system. However, this filter works great. I switch it out every three months.
