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.

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.

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

I had been using a cheaper change every month filter and decided to try these. They are made much better so thinking they may last two to three months. So far happy with my purchase.

These are the best AC filters I have ever used! I will never use another brand again. I noticed the air quality immediately for the better. Great price as well.

These were a perfect fit and are doing a great job! With a pug (known for heavy shedding) and a smoker in the house, these filters have made a big difference in the air quality. Great price and fast ship too.

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.

A necessary piece of equipment for every home’s furnace. I know price is a topic to avoid but compared to a 10 pack bought last year the cost has crazy skyrocketed! The only negative in this review.
