Customer Reviews
Reliable for replacement filters
I've been using FilterWater.com for my replacement filter cartridges for a couple of years now. This time I ordered a few Sediment Filters and Carbon Block Filters. They always have the models I need in stock, and the pricing is consistent. This order came in 4 days, which was pretty standard for them. I like knowing I can just go back to the same site and get what I need without any hassle. No complaints, they're reliable.
Decent price on whole house filter
This was my first time buying from FilterWater.com. I needed a new Whole House Water Filter and saw they had a sale going. I got a pretty good deal on it, which made me decide to try them out. The filter arrived in about a week. Installation was straightforward. I'm happy with the savings I got and the quality of the product for the price I paid.
Good filters, shipping could be faster
I ordered a set of replacement filter cartridges for my under-sink system. The filters themselves fit perfectly and seem to be doing their job well; the water tastes clean. Shipping took 5 days to reach Denver, which felt a little slow compared to some other online stores. The packaging was adequate, and everything arrived undamaged. Overall, a solid purchase, but a quicker delivery option would be nice.

Share tips, ask questions & help fellow shoppers save more
How are returns if something doesn't fit or I change my mind? Is it a hassle?
Does anyone know if their filters are actually NSF certified? Kinda important for my drinking water.
Can I use like two different promo codes on one order? Got a first-timer one and another for a bundle.
Anybody compare Filterwater.com's prices or selection to like DiscountFilterStore or Tier1 Water? Trying to decide where to buy replacement RO membranes.
What's the deal with shipping times? I'm in New York, trying to figure out when a new sediment filter would get here.
