Customer Reviews
Good filter, took a bit
I bought a Replacement Filter Cartridge for my fridge. It was easy enough to find on the site, which was nice. The filter itself works just like it should, water tastes fine. Shipping took like 6 days to get to me in Oregon, which felt a little long, but it got here eventually.
Great value on whole house
I was looking for a Whole House Water Filter and found a really good deal here during their anniversary sale. I compared prices with a few other sites and this was definitely the best bang for my buck. Got free shipping too since it was over $99. The system arrived well-packaged. The only thing is I wish the installation instructions were a bit clearer, but overall, felt like a smart purchase for the price.
Great value on whole house system
I was looking for a Whole House Water Filter and FilterWater.com had a sale that caught my eye. I snagged a system for about 15% off the usual price which felt like a really good deal. Shipping was free because my order was over $99, which saved me even more. It was a big purchase, so getting a solid discount made me feel a lot better about it. The installation was straightforward too. Definitely worth the money.
Good prices, slow delivery
I bought an Alkaline Water Ionizer here because the price was better than other places I checked. The checkout process was smooth enough, and I found a small discount for signing up for their newsletter, which helped. However, it took 8 days to reach me in Arizona, which felt a bit long. Everything arrived in good condition, and the ionizer works as expected. I'm happy with the product itself.

I was looking for a whole house water filter system and compared a few sites. FilterWater.com had a sale going, which made their system very competitive. I also got free shipping since my order was over $99, which was a nice bonus. The system arrived well-packaged and the installation instructions were clear enough for my handyman. It feels like I got a good deal, and the water quality improvement is noticeable. Definitely worth the price I paid.
Fast delivery, perfect fit
I needed new Sediment Filters for my well water system and ordered them from here. They arrived super fast, in just 3 days to my place in rural Ohio! I was worried about the fit but they were exactly what I needed. Everything went smoothly. I'll totally be buying my filters from FilterWater.com again!
Good filters, took a bit long
I ordered some Replacement Filter Cartridges for my under-sink system. The filters themselves seem great, they fit perfectly and the water tastes clean. Shipping took about 8 days to get to me in Florida, which felt a little slow. I needed them sooner. But overall, happy with the product.
