Quality of filter seems great. We have our first set in now. The frame holds up nicely. It fits snug. I am noticing a “clean” smell from the air filters when my air conditioner kicks on.

I have used 3M filters for years. I would buy the 1500 version at the home improvement stores. Sam's has the 1600 version (better) and it is cheaper. What is not to like?

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.

Excellent whole house filters that don’t degrade under heavy air flow as others I’ve tried. A bit pricey, but worth it the peace of mind and allergen reduction.

I have just changed the filter so I can't say anything about the filter yet. I did have directions that were easy to follow. I had no difficulty installing the filter

Been using these for 3.5 years now and they are doing a great job plus when you buy them at Sam's on sale, that even a better thing cause it's a great deal!!

Comes in a pack of 4. Hard ro find size. Got tired of waiting to order elsewhere. Friend came over and easily replaced. I have asthma and know when it is time. Have ordered them before.

Have routine a/c filter change etc in Oct but looking at the same size, same company the new one looks 5 inches larger. Waiting to see if it will work. Strange

With all the pollen in the air, I don’t know what we would do without these filters. They do the best job capturing the junk in the air. Plus Sam’s Club price is the best.

Great price, especially when on sale, and worth buying four at a time. I've purchased in the store as well as having them shipped and they arrived in great condition.
