Very well made, easy to install and the fit is right, but check your owners manual or HVAC professional to be sure it's appropriate for your unit. I got a scolding and was told to use something rated MERV 8 or less to avoid straining my equipment. So I now hope Sam's will stock a wider range of options, because I did like this brand and style.

I have been buying 3m filters for my ac from SAMS club for years but the last batch has issues. I think it is too restrictive and causes my furnace to cut off or short cycle. A new filters fixes the issue but returns in less than 30 days, I can feel the decreased airflow in the registers. Also, I recall the 3M filters used to have rounded folds in the filter material however these newer ones have very sharp folds like a W or V. I am not sure if the earlier version had a lower merv rating. I can no loger use these for more than 20 days, and we do not have any pets or a dusty house.

These are very good filters. I change them every 2 months and they seem to help with dust and pollen.

Value, functionality, and convenience. Short of next weeks winning lottery numbers... What more could you ask for...?

I am pleased with the 3 month life of these filters, and the app that will remind me to change them. durable and appear to be high quality.

These filters arrived quickly and neatly packed. The value for the 1600 style filter is very good considering I have paid more for a lesser quality filter from another online retailer. I’ll order these again.

I have to buy filters and replace once every couple of months due to my dogs and this is the cheapest place to find them. They are almost $20 any where else.

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

Filters Are great. We have 3 cats that adopted us and a lab my son adopted to us and these filters handle the hair and dander just fine . Not to mention they’re better value than the merv 11 I was gettin online.

These filters catch the dust and pollen that others let through. I am very pleased with these filters, they are not as inexpensive as the others but do a better job., NO MORE SNEEZING.
