BEST FILTERS EVER!!!

By Man in 40s from Waggaman, LA on 9/6/2020 7:24:45PM

I was looking to save some money by buying filters in bulk. Figured I would get filters like the big box stores sell. Boy was I wrong. These filters are crafted and much better quality than you get from the store. They are not flimsy or have material that is almost transparent. I will not go anywhere else for filters again. I will buy my yearly supply from Allfilters.com and tell everyone I know to get their filters from here. Have no doubts when ordering your filters.

Product seems to be what I ordered -- haven't used yet

By Woman in 60s and over on 9/2/2020 8:52:49AM

Product is just more Merv than I have used before, going from 8 to 11. The 8s worked well but I just thought a higher Merv might protect my system better. I thought the price was good compared to other suppliers & since I change them out each month, the cost is a consideration, as well as protection.
