Its just 25 days I used this product. My wife felt a change in dust layers on furniture n felt air more fresh n not muddy smell.

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'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.

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'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?

Useful to keep your home's air as clean as possible, and improves the operation of HVAC units.

Very satisfied with the product. Hoping it helps with my family’s allergies. So far so good.

These filters are sturdy and do the job they are designed to do very well.

Not nominal size as printed on package, ONLY FULL ACTUAL size, had to return!
