Crushed Filters
on July 25, 2025
Posted by: Anonymous
The company needs to learn to properly package its products. I purchased a pack of 6 small (10101) filters and two of them are crushed beyond use. That increases the cost by 33% and the inconvenience factor by 100%. I can't address the quality of an unusable product.

I have dogs and cats which means lots of hair and dust. Wanted a good quality filter and these are just that.

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.
