I've been using this brand and type of whole house filter for several years now and I'm pleased with their performance. The filters are better than the normal type found at Lowes or Home Depot. By better, I mean that they filter finer particles and they seem to last longer than the standard type of filter. Sams Club prices are good too.

Received about a week ago. These filters have been my salvation through out all our State Fires. Thank You! 3M and Sam's Club. It has also worked very well through the Pandemic. I was using the next upgrade filter. It is even better and I prefer! Thank You!

As far as air filters go for a HVAC heater these do an excellent job. I change ours every three months and these filters definitely filter out the stuff you do not want coming into your house. As long as you keep the vents clean these air filters do their job very well. I will not buy any other filters.

I really like these filters. We live on a farm (with animals) so our house is always dusty with dirt being constantly drug in. But these filters do a very good job of keeping the dust & dirt down and help with the allergens that we battle. They are not meant to keep a house spotless (oh, how I wish!) but I am pleased that they do as well as they do. I also like having a package of 4 filters, so I don't have to worry about running out abruptly. I have been using this brand and selection for several years and will continue to use them.

Great job on dust elimination & clean air when changed every 3 months. Also does a nice job w/ air flow vs. some other filters that might filter well but restrict flow to the air handler (which can stress the unit). Even better deal w/ the savings that Sams has every now & then.

We have a cat, so a good quality filter is needed with her dander and dust from her litter. It's probably minimal in the scheme of things, but it's more than a home without a car. These filters are great, and come in varying levels based on the amount of allergen protection you need. We only have to change them every 3 months, so this is literally a year supply and at a competitive price. If you have the plus membership, shipping to your home is free, too!

I’ve been using this brand of filter for over 20 years 20x25 in my previous house and now 16x20 in my new house. Always bought them from the local Sam’s Club but we moved and now with the convenience of ordering on-line with free shipping it’s a fabulous bargain. These filters filter 100% and nothing gets through. I bought 5 packs of 4. I’ll be good for a long time.

I have cats in my house and so you know any filter I use is working overtime and this one is doing an excellent job. The furnace installer said these are one of the best if not the best and the savings from buying them at Sam's makes it a no brainer.

Furnace filters really work well; changing them frequently is really a good idea so purchasing in a 4 pack means they are on hand. It is even more importand during the pandemic to keep the air quality as clean as possible. These filters work wonderfully well to do that.

These have cut down on MUCH dust! When I burn candles? My filter gets blackened:) They catch a LOT and can’t imagine how I got along without these Awesome Filters:) (psssstttt.... are times I forget to change when should...... and..? well.. They keep getting dirtier! Am ashamed to say but! Truth! They do their job well! And yes., I do write the date on the filter to remind me. hah!
