These are great furnace filters. My local big box stores were sold out so I ordered this twin pack. I have used Filtrete filters for a long time as I think they are the best.

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.

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.

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.

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.

Very happy to buy these online with reliable Sams Club. I was going to use another online vendor but I saw that Sams Club sold them. These are the filters I have been using and the price was right.

Great air filter

Keeps the air flowing!

Usually we have no issues with these filters. They worked great in our HVAC system for years. Now with that said my last orders the filters are running smaller. There is a major Gap in with on all sides, I can hear my AC is whistling and I can slide my finger in between the framing, very disappointing. I am afraid to order these again. What’s going on? As you can see I have placed a folded newspaper on top edge and size edge to help it fit and not flop around while the fan is blowing. Hope this doesn’t harm my system. Not have the funds to purchase new ones at this time. My last order was 2 Box purchase a total of 4 filters.
