This price is great for 4 of this fillters. Typically pay $20 a piece at other big box store. Thank You Sams

These are the very best filters that you can buy. Sure hope they keep them in stock and available next year.

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.

I have not use but I have order before and use the brand but this time the price was higher and no rebate or discount,

Four pack of 12 x 12 air filters cost $20 ea at Home Improvement stores. So four pack for $39.99 is a deal.

Possibly the best whole-house air filter there is, the $10 discount is greatly appreciated in these difficult economic times!!!

It's great to grab a bundle of these to have on hand, now I have no excuse for not changing the filter regularly

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

As soon as I installed these filters my wife stopped sneezing. She had been suffering for days. What an endorsement.

I have liked and used Filtrete filters for many years. This is a great price for a product I usually buy.
