Not always easy to find correct sizes or MERV rating, so when I see them on sale, I have to get them!

I was sneezing all the time from cheap filters. I switched to these and everything cleared up within hours.

These filters are very good. They are also very very expensive but the convenience of getting them while I'm out is why I buy them.

Filtrete is the “top of the line” in furnace filters, and I don’t recall ever getting such a good price anywhere

I shopped around on line to buy it locally, and Sam's Club had the best deal. National brand, high quality, and they fit and work well.

I’ve used different brands and 3m filtrete is the best I’ve tried without the ones paying an expensive price.

These filters are great! Arroved nicely packaged and seem to work well. They were a great price as well

I always purchase these at Sam’s Club and try to watch for instant savings. They work well and they normally have my size in stock.

These filters do a great job of capturing all the harmful particles that can cause problems for my wife's COPD. Highly recommend this product.

These are the filters we depend on. Their efficiency is obvious via the dog hair, lint, and dust accumulation after 2 or 3 months.
