Customer Reviews
AC filter came fast
I ordered a MERV 8 air filter for my AC, and it got here pretty quick, took about 4 days to reach me in California. It fit perfectly, no fuss. The website was easy to use too. Good experience all around.
Always reliable filters
I've been getting my refrigerator water filter and furnace air filters from Filters Fast for a few years now. This last order, for a refrigerator water filter, was just as consistent as always. It shipped out fast and arrived in good shape. I signed up for their Subscribe & Save a while back, which makes it super convenient and I never forget to change them. Their own brand filters are just as good as the more expensive ones I used to buy. That's why I keep coming back.
Good deal on a fridge filter
I was looking for a new refrigerator water filter and saw Filters Fast had pretty competitive prices. I signed up for their newsletter and got a little discount, which was nice for my first purchase. Shipping was free because my order was over $99, so I grabbed an extra furnace air filter to hit the minimum. It definitely felt like I got a good value for my money, especially with the extra filter thrown in. The filter itself works fine, water tastes good. I'm happy with how much I saved.

Hey, wondering how long shipping usually takes for these guys? Need a new fridge filter pretty quick, I'm in NYC.
Anyone know if you can use more than one coupon code at Filters Fast? Got a military discount but also found a free shipping code.
