There are cheaper filters but these are of excellent quality. One of these filters lasts us about three months. We have a lot of agricultural dirt & grain dust in the area in which we live. The extra filtration qualities are worth the price.

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?

Filters Are great. We have 3 cats that adopted us and a lab my son adopted to us and these filters handle the hair and dander just fine . Not to mention they’re better value than the merv 11 I was gettin online.

I've used these filters before, and they seem to work great. I've not noticed and issues with the HVAC system. Sams Club are much less expensive than most other retailers for the same filter.

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!!

With two heavy shedding canines in the house along with the dust that magically appears daily, these filters a must in our house. They really trap an amazing amount of "stuff" which helps to clean the air in our house.

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

We found not many places carry filter size we need for new home. We can get excellent filters on sale price right here and delivered to home at no extra charge.

Just in time for the start of our spring allergy season as I clean the tree pollen off of the car. I typically use the dust grade until the allergy season arrives. These are an excellent upgrade to capture finer allergens.

Product is super, packaging was perfect. The FEDEX delivery left slot to be desired. The tracking process reported as on truck in area on Wednesday. The order was "out for delivery" on Thursday, Friday, Saturday and finally delivered on Sunday.
