We use the 20"x25"x1" inch in our home. Given the level of MERV for the price and the number of filters provided...definitely a good price compared to other stores. I usually wait to catch these filters on sale. I wish they carried the 14"x24"x1" in store, but understand that it is a less common filter for general use.

Look! I had my attic coil cleaned, the guy went up and came back down!! I said “ boy you are quick “ he said my coil was as clean as he has seen. All due to changing my filter with Filtrete filters!!!

I have been using these since Sam's started carrying them. The work great, fit perfectly. A solid product. Replace them every three months and haven't had any problems with them.

These have been a staple of mine for years. The new color threw me off for a bit, but these are slightly better (1600) than the purple colored ones (1500) I usually buy. These do help with cutting down allergens in the air. I also like that they are solidly constructed and remain good for 3 months. This four-pack was a good price.

This brand of air filters is really making a difference in the overall air quality of our home. They are well made a catch an amazing amount of dust and allergens compared to some less well made filters. A bit expensive but thank you Sam's for your bulk buying and passing the savings to your customers.

After using these for six years, the inside of my AC unit is almost as clean as when it was installed.

They work well, however, I've been told that in the summer months you should use a filter that you change out every month. I believe these filters don't allow easy air flow.

Honestly I didn't want to go as high as MERV 12 for my 2-ton SEER 14 HVAC system, but the brand I was purchasing MERV 10 filters from lowered the quality of their products. 3M makes good products and as long as my system doesn't work too hard to push air through filters this high rated then I believe it'll be fine.

It is absolutely outrageous how these large companies continue to take advantage of the hardworking people by pricing items like this so ridiculously high. There is no reason for the huge price increase in this product! The quality hasn't increased. The amount of time they last hasn't increased. Nor has the amount that this company pays their employees increased. And yet the price that they charge has gone up dramatically.

I did not receive 2 packs of these, BUT they charged me double $86.56 at the door. 3 employees couldn't delete them. So I gave them back to the checker. Called when I got home & was told I would need to do this in the store, which involves a 30 mile one way trip, more diesel, wear on my truck & me!
