Love buying these in bulk$40 for 4 such a great deal

It was a great offer for all of them

They seem to clean the air pretty well

Fairly well priced and they work

Good price on a good product.

Great filtration, good for you, your air and your system.

Definitely the best ones to use if you have a compromised immune system.

I have used these filters for years they always work well for what they do

Great filters can't beat Sam's prices

I've always used Filtrete furnance filters and had no issues
