These filters are bodacious! I breathe better than ever now. I can feel the air pumping through. Clean, fresh, delightful and pure! Other air filters are not as good. These are best that can be!

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!!

Better quality filter for about 25% less than what they charge at the major home center retailers, and that was before the additional members savings I received.

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.

Great Filters to use, our service guy said we could go up to 3 months before changing them out with good filters. We change them every 4 - 6 weeks but knowing we could go longer using a good filter is good to know.

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.

Love these filters!! I have been using them for a number of years now and have figured out that changing them out every two months works best for me. I try never to run out of them even if I have to buy a single filter elsewhere occasionally.

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?
