They are good. Just had

They are good. Just had trouble putting one on when AC was running, kinda sucked it in and air pressure bent it, but it still worked. Maybe wait until ac stops running. Lol

Excellent

I was pleasantly surprised to actually get the filters on the next day! Filters are currently being used and are performing as expected. Thank you

New FilterBuy product appears to be much stronger!

Pleats in newest filter appear to be much stronger and should perform better than those in the past. I won't have an opportunity to evaluate this until 1st Qtr 2026, since I still have ample inventory from my last FilterBuy.
