Quality product that does the job our HVac person told us a good quality filter changed monthly will extend the life of our furnace/ac. And it certainly does.

Fair price and high filtration. We change the filter at the start of every new season so four will last one year. They are well made and indeed do the job.

I purchased the Filtrete 90 day filters while an instant value and received a one year supply for $6 off the regular price. I trust these filters to keep my furnace and A/C operating at good performance.

Great price, especially when on sale, and worth buying four at a time. I've purchased in the store as well as having them shipped and they arrived in great condition.

Been using these for 3.5 years now and they are doing a great job plus when you buy them at Sam's on sale, that even a better thing cause it's a great deal!!

The best when it comes to necessary for the home. Living in Florida where we have lots of allergens, and especially during dry seasons, we all want the best filter available for our homes.

this is the greatest value on a four pack. Just buying one of these in the store is around $18. Great price this was for 39.98 for 4. Best ever filter

I have used 3M filters for years. I would buy the 1500 version at the home improvement stores. Sam's has the 1600 version (better) and it is cheaper. What is not to like?

I’ve had a “smell” that I couldn’t place and I thought it may be coming from the register area. Wasn’t strong very faint. These filters are higher quality and it did the trick. Worth every penny.

Easy to order the ac air filters online using the Sam’s app. Easy check out. Saved money by ordering bulk. Also saved me a trip to the store and free delivery.
