  • Great value and huge difference in taste and odor
Color: Black-basic
Honestly, this is probably my best purchase on Amazon and trust me, as an Amazon Prime member I order from them constantly!! I am extremely pleased with this Waterdrop filter. It is very easy to install as it connects to your cold water line and voila, super clean and great tasting water from the tap! For years, I was a slave to lugging bottles of water home. I preferred purified water only and bought the 2.5 gallon containers with the tap. With all of the brands of water on supermarket shelves, you’d be surprised how little the selection is when it comes to “purified” vs. “spring” water. This meant I had to go to the local pharmacy because they always carried it. Purified water was essential for me because I received a bone marrow transplant some years ago and spent many weeks in the hospital for the procedure. I am a huge water drinker and the ONLY water offered in the hospital to BM recipients was purified water. Hence, I continued to drink only purified water because of its higher level of purity when compared to spring water. So, basically I’m a water snob lol. While selecting a filter, I was obviously concerned about the quality and taste, but also the possibility of a loss of pressure. I’m happy to report that the Waterdrop filter addressed my concerns and exceeded all my expectations!! I do not have my own well. Instead, my neighborhood has a community well that treats the water and we are all charged based on usage. Still, the taste was awful. Also, it contained a high level of lime scale which clogs up my sprayer heads so I have to use cleaning products to remove it. It is also has a noticeable chlorine odor and taste. With this filter, my water now tastes clean, “nonminerally” and its odor free. The cost savings is huge!! I can’t believe how much money I poured down the drain. Also, there was no loss of pressure. Keep in mind it hooks to your cold water supply. This is fine because who consumes 8 cups of hot water a day anyway? For cooking, I use cold water that gets heated up anyway. My coffee tastes much better. Also, it’s better for my pets! I highly recommend this water filter. It is a great value and saves you a considerable amount of money in the long run! It is more practical than water pitchers that require filter changes. I’ve had it installed for 3 months now with no issues. I’m pretty sure you will feel the same way. ... show more

  • NYC apartment renter
Color: White-premium
Now I live in NYC and I’m a renter. The building is old and the pipes are old. This cold water under sink filter works was package well and it works very well. When I turn on the cold water the filter is quiet and the water flow was fast as if I didn’t have a filter. I never realize how much I needed this.. it is affordable. I purchased 2 one for my kitchen and for my bathroom. I always thought that homeowners was the only ones that can use these. Silly me. If you are a renter like myself get this. It is worth it and it works. I let the filter run for about 5 to 7 minutes to clear out any debris from the inside and the water went from cloudy to Chrystal clear. And I’m more confident to cook with this water, compare to waiting on the pitcher to filter out. Also it is very simple to connect under sink. Only downside is I can’t filter out the hot water. ... show more

  • Great filter
Color: Black-basic
Easy installation and good instructions. So far, very pleased with the filter. No decrease in water pressure and the quality of the water (no smell, good taste) is great.

  • Easy to install, Great start, water is clear and no bad taste.
Color: Black-basic
I was looking to replace the filter from Woder but they no longer sell them or are way expensive than what they were before. This was looked like a good replacement and decently priced. Easy to install. I recommend installing and mounting the filter base first. Then install the water hose connectors to your water line first BEFORE connecting them to the filter base. If you connect them to filter base first you will be wrestling with it while trying to install them to you water lines. Especially in a tight space under the sink. It comes with everything you need to install, even a set of stickers for the month to remind you to replace the filter when it's time. I like this install once and done, change the filter only setup. As for the water, there is no bad taste, clear, and ice cubes almost come out clear. 4 stars for now, will see how it holds up in 6 months. ... show more

  • Easy install
Color: Black-basic
Very easy install, water seems much cleaner now. I do not notice any bad tastes now and have not had an issue with water pressure. Built to last and work great! Mine is right under the sink and I forget it's there with how small it is at times.
