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.

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.

Since I have terrible allergies, I appreciate the utmost filtration of the air inside my home. These help achieve lower pollen count inside my home, therefore improving my quality of life.

Best filters I have found for our home. Very pleased with them. You should change your filters every 30 days, however, I have gone 6 weeks with these and still had good filtration and flow.

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.

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?

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!!

These are the best AC filters I have ever used! I will never use another brand again. I noticed the air quality immediately for the better. Great price as well.

Comes in a pack of 4. Hard ro find size. Got tired of waiting to order elsewhere. Friend came over and easily replaced. I have asthma and know when it is time. Have ordered them before.
