Customer Reviews
UV sterilizer works well
Bought a UV water sterilizer. Arrived on time. Installation was okay. Water quality improved. Happy with the purchase.
Got my new fridge filter
Needed a new filter for my fridge, you know, the one in the door. Found it here, price was decent. Ordered it up, and it got here in like a week. Popped it in, no issues. Water tastes good again, so that's a win. Easy peasy.
Good filter, quick shipping
I ordered a replacement carbon block filter for my under-sink system. The ordering process on the website was straightforward; I found my model easily. Shipping was pretty fast, it took about 4 days to reach me in California, which was sooner than I expected. The filter itself was well-packaged and fit perfectly. I've noticed a clear improvement in water taste since installing it. Customer support wasn't needed, but the product quality seems solid and installation was simple enough for anyone to do.
Reliable for replacement filters
I've been getting my replacement membranes and pre-filters for my reverse osmosis system from WaterFilters.net for a few years now. This latest order for the RO membrane was just as good as previous ones. They consistently have the correct parts I need, and the quality is always reliable. Shipping usually takes about 5-6 days to New York, and this time was no different. It's why I keep coming back – I know what to expect and they deliver.
My water tastes so clean now
I finally got around to replacing my old shower filter and bought one from WaterFilters.net. What a difference! The water feels so much softer, and my skin isn't as dry after showering. I'm so happy I bought it. The installation was super easy, too. It came in the mail pretty fast after I ordered it. I'm telling all my friends who complain about their water to check this place out!
Waterfilters Community Discussion
Share tips, ask questions & help fellow shoppers save more
Hey guys, thinking of grabbing a whole house system from waterfilters.net. How long does shipping usually take to, say, California?
Anyone compared WaterFilters.net to DiscountFilterStore? Looking to get a bunch of sediment filters and trying to figure out who has better deals for bulk buys.
Are the filters on this site actually genuine? Like, if I order a brand name, is it really that brand or some generic knock-off?
Can you stack coupon codes on waterfilters.net? Got a newsletter discount and saw another one somewhere else.
What's their return policy like? Bought the wrong size filter before from another site and it was a nightmare to send back.
