I use them all the time-good buy for the price.I wish they were available in all Sam's Club stores (size)

I have been buying these filters for many years, and they really do the job. Specially, if you have allergies, I would recommend them. Good buy

My son an HVAC technician said too high of a rating makes your furnace work harder. This was the only filter I could find that fit my furnace

I buy these filters all the time... Well every 6 months. The MERV ratings are exactly what I'm looking for in an air filter!

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.

Love them. Actualky catch all the fine dust and pollen that has been coming into our home, rather than ruining the AC unit by letting it ruin the coils or blower box.

I'm unable to give a review at this time regarding quality or performance. I bought these because they were a good value and I expect they will perform great but until I use them I can't say with certainty.

Just started using this product. Too early to tell how it’s working. Not sure I will be able to tell if it works any better or worse than the last filters I used

I've purchased this item several times. Overall I. Stified with its performance The only negative is, the filter turns black (some of them, not all) after about 3 weeks. No smokers in the house. Minimal fried foods, we seldom use candles. My Ac guy said it could be activated charcoal but the package didn't say that. What causes this?

Buying these filters at Sam’s Club is very cost efficient.
