Much less expensive then hardware store and very good quality - delivered to my door!
I bought these filters after visiting my local name-brand hardware store and pricing filters in two-packs (highest bulk available for the size.) I also read what the numbers mean. I bought a 6-pack of #8 from Atomic Filters cheaper per filter than the #7s at the hardware store. And shipping was free. Do the math. Higher quality for less money.
Impressed by the speed with which my order was delivered - and without a single scratch. That is good service!
