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!!

Always bought these AC filters at Sam's when on sale. Good value and it works. Online site shows all the sizes. Free delivery via UPS or FedEx for Plus members. Recommended.

We’ve been using these filters for a couple years and they seem to work fine. I tried to find a cheaper price on them and couldn’t. Sam’s is where it’s at.

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

These filters are bodacious! I breathe better than ever now. I can feel the air pumping through. Clean, fresh, delightful and pure! Other air filters are not as good. These are best that can be!

Hi quality filter that works great. We change the filters every three months, seems about right here in the desert southwest. Great price at Sam's for a 4-pack, and usually in stock when we need to restock.

Nice filters. We buy them when they are on sale. The multi pack is a better deal than buying them individually. They work great! We change them monthly during high allergy times. Can go longer at other times.

Excellent whole house filters that don’t degrade under heavy air flow as others I’ve tried. A bit pricey, but worth it the peace of mind and allergen reduction.

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 like this product. Seems to catch more airborn particulate than the cheaper filters. I have 2 rambunctious kittens, always stirring up dust bunnies while playing.
