Excellent filtering product. Amazed how much is trapped in the filter after 2-3 months. My primary complaint is that the product line from 3M is expensive and their best really takes a jump in price. If you have family with allergies I'd say invest in the better producs.
Best filter for dog and cat hair, it really does capture the junk floating area our house. Or three pets really play hard in doors and its amazing how much junk does collect on the filter..
We have always used Filtrete filters, recently switched to the best filter. It really cleans the air and it's hard to believe all the particles it collects. We have one dog and three in our family. We are very satisfied with the Filtrete filters and will not change to any other.
