These are made with a much sturdier frame holding up better to installation and moisture. Like anything 3M seems so much better quality overall.

Filters are wonderful. I can't say too much for the shipping. The package was smashed and filters were all smashed, but I fixed them up.

This filter is excellent for the dust storms and all the blowing sand during our storms here in the Phoenix area. It works great and the price at Sam’s Club is excellent.

We shopped around buying filters from different stores, buying filters online through subscriptions. Not only are they more expensive the Quality is not the same. With a membership We get 4 filters for the price of 1.

I love these filters! Great choice of filtration by Sam’s and great price. I have 6 parrots which give off dust! This particulate is important ti be removed from my iPhone air. I purchased 12 for a full year’s supply!

The filters are good and was cost effective when I was shopping around! I gave it a 4 star because there was a bug on one of them when I opened it! But other than that, what I needed it and good deal for the price!

Great to see these in side the Sam's Club store considering that are a very pricey piece of equipment wherever you go. Therefore seeing then in bulk only helps the customers.

I always purchase these air filters but from a different store. The product is great. The value at Sam’s was much better than I could get anywhere else.

Quality filters at a good price

Good deal for good filters
