These have made a big difference in the amount of dust we get on our furniture. Plus the price for 4 is what you would pay for only 2 at most other stores.

These are the best filters I have ever purchased. They cut dust to a minimum making house cleaning for me so much easier. And such a great value for an average of $10 each. I replace them every 2 months.

These filters are the best I have used. They get pet hair, dirt and dust although I have cats and dogs so I actually change my filter every month but it does cut down the dusting

We've used lower rated Filtrete filters that work well. I bought the Ultra because the others were out of stock. If you buy any Filtrete filters, I recommend changing them before your system shuts down from lack of air flow. They are that good!

The filters themselves are good. The delivery, not so good…..one corner of shipping box was smashed and wet when received. Filters inside had corner damage and were wet. I live far enough away from Sam’s that I decided to use instead of trying to exchange…. Dried them out so should work okay.

I appreciate the price Sam’s club provides us for this air filter. It’s almost half priced as compared with the other retailer. The 3M quality is always the best. I can immediately feel fresher air in my home after replacing the old filter with this one. I bought 12 packs with this price, enough for next 3 years. I highly recommend this product to everyone.

These are the best filters we found at any store, including the local hardware stores. We wait for them to go on sale, and usually buy two packs, as we change our filter every month. Thus far, we feel that these filters are helping to keep our furnace cleaner and our air clean. Definitely recommend.

I only buy Filtrete, they're the best. Unfortunately my 10 year old furnace died 2 days after I received these filters and I never had a chance to use them. Replacement furnace uses a different size and the company I used provides free filters for 2 years so I will be returning these. Will buy the new size from Sam's when the free filters run out or if I decide the free filters aren't doing the job.

Excellent filters at a really good price! These really eliminate the finer dust and pollen particles in the air in our house in SC. We have noticed a drop in accumulated dust on horizontal surfaces in the house since we switched to these very efficient filters about 8 months ago.

My friend recommended these filters and I'm very happy using them. The air is a lot cleaner; I don't have to change the filter out for 3 months. I highly recommend, although pricey, it is definitely worth the money. Also, they have a reminder when to change out filters.
