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.

[This review was collected as part of a promotion.] great product and price

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

Fit perfectly and aided tremendously in the process of removing mold from my mothers home. The ones made specifically for Honeywell weren't cutting it.

These are a little pricey. I have used some "generic" one with a higher MERV rating with better results, but cannot always find those. These do work pretty well, but need changed more frequently.

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.
