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.

Great product. It does what it says it's supposed to do. I change them every 3 months. I had my furnace looked up and they said it's one of the cleanest they've seen in a long time.

I usually buy the filter with less coverages, because I do not need the additional coverages, so I had to spend more money. My income is limited. I believe you should have more than one option to choose from.

Love these filters!! I have been using them for a number of years now and have figured out that changing them out every two months works best for me. I try never to run out of them even if I have to buy a single filter elsewhere occasionally.

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.

Quality of filter seems great. We have our first set in now. The frame holds up nicely. It fits snug. I am noticing a “clean” smell from the air filters when my air conditioner kicks on.

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

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.

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.
