Filtrete is a very good filter. Traps the pollen this time of year. I have a dual heat pump that has different Returns and the settings. One upstairs and one downstairs in the ceiling. I also have a larger return in the Den. All work well with Filtrete filters. Rarely have to dust!

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.

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 know HVAC workers will cringe when I say this, but we really like these better than the cheap ones they HVAC workers say to use. I don't think they're a waste of money. Having the pets we have, being smokers, and living in an older house that's hard to keep dust and dirt out these help much better than the cheap ones. Instead of changing the cheap ones 1 or 2 times a week, we can sometimes go almost a month with these

I always buy 3M filters. They feel like they work the best and are well worth the extra money than the plain-jane filters. Not only do we live on a gravel road in the country, we have 2 dogs that are inside/outside and shed. I also have some allergies, These filters help tremendously!

I own an older home. My HVAC air return is an odd size. Can never find it at other retailers. Its always in stock online and at a better price with Sam's. I place my order and 2 or 3 days later the box is delivered to my front door! No shipping charges since I'm a plus member!

I have used Filtrete filters for years and they are consistently effective in pulling pollutants out of my home leaving it much more fresh. With droughts and dust a real problem this year the allergy causing agents are plentiful and everyone needs to use the higher grade filters for easier breathing!

Rating is not based on scientific analysis but based on observation and long-term use. The 1600 MPR appears to substantially reduce as claimed pollen, pet dander, smoke, bacteria and viruses. The latter two elements cannot really be determined. Changed every 2-3 months and the amount of collected debris in the filter is supported of filtering.

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.

We had a difficult time locating the Ultra Allergen 2X Bacteria and Virus Filters in the correct size (18x20) for our furnace, but finally found them online from Sam's Club. We are grateful for the ultra-allergen / 2X bacteria and viral protections provided by the 3M Filtrete Filters. We also appreciate being able to shop online at Sam's Club even though we are not members. Wow!
