I love these 4 packs! They are the most affordable way to purchase air filters. We love them because it helps keep our air quality up with 3 dogs.

Great value pack of filters that do a super job in your furnace filtering out dust and allergens. Highly recommend Filtrete brand air filters.

I have read filtrete is the best, I know that they're the most expensive but I have been using them for years, wish they cost less.

Excellent filters, fantastic price compared to what I normally pay, and delivered to my door, I couldn't have asked for more!

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.

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.

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

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.

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?

I always used this product so far no problem
