What Our Customers Have to Say

I buy all my filters in bulk from Disc Filters. Partly because my 24x24x3 is often hard to find. I settle if needs be for 1". And partly because we I hate to use big companies like WalMart. Many of my filters over the years are USA made. Many are not. But at least I can choose. At WM and such there is only whatever best suits their bottom line profit. I prefer a smaller company. They have excellent customer service, too.
