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!

We've used these 1600MPR type filters from Filtrete for several years in our 1400 sq foot, 2-story condo. It does a good job for its intended purpose as near as I can tell. Although I'm not able to see allergen, bacteria and viruses, I do always see a discoloration on the pleats when I change-out the filter at 3-month intervals.

These are good filters. They are good quality and stronger than the cardboard filters. These have a wire mesh on both sides and stay firm and strong with the air flowing through them. They hold a lot of dust and keep the AC unit very clean. Keeps a lot of dust from flowing into the house. Keeps the air cleaner.

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!

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.

These filters work very well & keep my house & vents very clean! No allergies either & priced a bit high but lower than at other places. I date them & change every 3 months. Once I vacuum cleaned them to reuse once and they held very well for over 6 months!

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.

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.

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 bought these "higher end" filters from Sam's Club (online) for a great price, and had them shipped directly to my home. I already knew the quality was good but I was shocked when the filters arrived with no damage whatsoever. No dents, no dings, no moisture . . . perfect. They were in better condition than what they would have been if I had bought them from a store in person.
