Customer Reviews
Good filter, quick delivery
Needed a new pool filter. Ordered a cartridge filter. It shipped fast. Got it in 3 days. Filter works well. No issues. Will buy again when needed.
Consistent quality, fast shipping
I've been getting my furnace filters and refrigerator water filters from here for about two years now. This last order was for Merv 11 filters and a replacement fridge filter, and it was just like the others. Everything came well-packaged and arrived in 4 days, which is pretty good for reaching upstate NY. The filters always fit perfectly, and the prices are still better than what I find locally. Good to know I can count on them for these regular purchases.

Share tips, ask questions & help fellow shoppers save more
Hey, wondering if their filters are actually good quality, like compared to the ones you get straight from Whirlpool or GE. Or are they just cheap knockoffs?
Thinking of ordering some furnace filters. How fast do they usually ship to, say, California? Need them kinda soon.
