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.

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.

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.

I believe the filters are good but the first one I put in seemed to get used up pretty quickly. Also didn't appreciate having to pay the shipping fee because they didn't have my size in store.

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.

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.

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.

We have people in our house with allergies and asthma. These filters have proven to clean the air from our HVAC better than others we've tried. The sale price at Sam's is the best value we've found.

Good value, had in my size without going to a hardware store. Very good filtration, but (and a good but) you have to replace the filters about once a month with the effectiveness of filtration.
