  • Love it so far!
Color: Black-basic
We had very chlorine tasting and smelling water from our tap. We used a fridge filter for drinking water and a Britta pitcher for the coffee pot. We got tired of the expensive filters so started looking for options. We are retired and on a fixed income so we didn't want to spend the money on a whole house system. Our plumber recommended a different brand under the sink filter. It was very expensive and the replacement filters were $100 each! With some research we picked this one. We did have our plumber install it for us. He said while installing that it was a very nice unit! He split it so the water goes to our fridge for drinking water and ice and also to our cold side of our sink water. I was floored that all of the chlorine smell was gone! We just turn the handle to cold for filtered water and hot or warm to rinse dishes etc. We love it! It says two years filter replacement but Even if we have to replace the filter once a year we would still be happy! ... show more

  • Easy to install, great customer service
Color: Black-basic
I got sick of paying $35+ for filters for my fridge icemaker, only to have them rapidly stop working. Decided to circumvent the fridge filter altogether, by installing this filter. It filters the tap AND the fridge water supply. It was super easy to install, taking about 30 mins. Just read the instructions carefully, and you shouldn't have a problem. Once mounted, the hoses stay put, and the cartridge comes off with a quarter turn, for easy replacement (turn water off during removal!). There were two little plastic clips that attach to the hose inlets to prevent accidental disconnects ( although there shouldn't be any reason to pull on the hoses, accidents- and children- do happen), and they weren't in my kit. I called the assistance line listed in the instructions, and the guy there was super helpful and they are sending an entirely new head plus the clips. I've bee using the filter for two days and no leaks, so happy for that. ... show more

  • So far so good
Color: Black-basic
We have a dedicated spout on our sink for filtered water for cooking and drinking. We purchased this filter due to its ability to filter PFAS chemicals out of drinking water. Since moving to NC, my family all gained an outrageous amount of weight without a change in diet. After research, found the regions drinking water has been contaminated with PFAS, which is linked to weight gain. So far the water tastes great and it's easier to drink water and not feel like we are being poisoned. ... show more

  • A simple installation
Color: Black-basic
A 20-year-old undersink filter exploded due to a crack. That model is no longer available, which is lucky, since I might have made the mistake of doing an exact replacement. Instead, I got this as a replacement. I wish I had installed it long ago. Filter replacement is so much simpler than the old one. We have a filtered water spigot beside our sink, and I installed this filter feeding that spigot. However, the Waterdrop is designed to filter all the cold water from the regular tap. It would have been so much better to have used this filter right from the start, but I didn't know about it those 20 years ago... ... show more

  • Works really well!
Color: Black-basic
I installed this under my sink because of the weird taste we have down here in Tampa Bay. What a difference!! Only been using it for a few weeks now so I don't know if it'll last over a year before replacement - we'll see. Actually bought another one for a house I'm renovating - new owners will get a nice value add! ... show more

  • Did the job!
Color: Black-chloramine
My water is so awful the dog won't even drink it and she eats 💩! Paid a plumber to do this as I have no experience in installing and he said there was a nut that was awful putting on and barely fit. He said other than that it was an easy install. Water tasted great and now I don't have to drag all these bottles back and forth from the store in the cold! Now we will see how long it lasts! ... show more

  • Water tastes much better
Color: Black-basic
I hooked my filter up only about a month ago even though I bought it four months ago. Water tastes, much cleaner, even though we still use Brita containers. There’s even a difference in the taste of our food.
