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.

Very inconsistent in size. The actual dimensions are bigger for a filter in the pack, while a different filter has correct size to fit the vent opening. Very frustrating!!

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.

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!

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.

The filters are good and was cost effective when I was shopping around! I gave it a 4 star because there was a bug on one of them when I opened it! But other than that, what I needed it and good deal for the price!

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.

Prior to using this filter the hardwood floor beneath our bed always became covered with lint/dust from the heat register. That's no longer the case with this filter.

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.

These filters made my furnace not be able to breathe. I had to call a technician to come to my home and it cost me $254 for him to tell me that I needed different filters.
