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’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.

Great price on a great product. We have a couple of rescue dogs that shed. That means I always have a need to change my filter often and to always use a good one. This fits that perfectly.

These were a perfect fit and are doing a great job! With a pug (known for heavy shedding) and a smoker in the house, these filters have made a big difference in the air quality. Great price and fast ship too.

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!!

We have tried different brands because we switch them often and they are a little pricey but they are so worth it. I see the difference in the air quality in my home.

A necessary piece of equipment for every home’s furnace. I know price is a topic to avoid but compared to a 10 pack bought last year the cost has crazy skyrocketed! The only negative in this review.

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.

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.

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.
