WaterdropWater Filter for Sink Faucet, 360° Rotating Stainless Steel, NSF Certified Water Purifier for Kitchen Sink, 3 Months Long Lasting Tap Water Filter, Reduce Chlorine, 1 Filters

First of all, this thing was super easy to install. I think it took me no more than 5 minutes to install. Second, the flow rate of the filtered water is so, so, so much better than the flow rates on Pur or Brita faucet filters. The water tastes better, too. I most recently had a Pur faucet filter before buying this one and that thing sucked. It was extremely slow to fill up my water bottles, and the filter replacements were expensive AND honestly the water just tasted meh. With the Water drop, the 64oz water bottle I use fills from empty to full - with *filtered* water - in maybe 15 seconds tops. This unit has a great flow rate and the replacement filters are reasonably priced. Finally, my experience has been that the filter replacements definitely *do* last approximately 3 months or so. Thats how often I change mine, anyway, and my water always tastes fantastic. Definitely worth every penny.

With the proper faucet fitting (included) the filter was easy to install. With the additional filter cartridges the filter should last a long time. Really makes a big difference in the water quality.

Easy to install and makes my well water have a nice and fancy taste! super functional for an everyday basis too!

We live in a place with an internally threaded faucet. It wasn’t compatible with any of the washers included in the box, which was frustrating but we bought the right one and got to installing. Due to the design of the filter and the style of our faucet, it isn’t perfect and feels a quite loose (though it can’t be tightened further), and definitely leaks a little. That all aside, it’s about the best we can do for our current bathroom situation so, it’ll stay for now.

“Now that’s what I call high-quality H2O.” I’ve used Pur water filters for years but this is another level of filtered water! Love the chrome, and the filter is not encased in plastic like other brands. Very happy with purchase

Does the job. Easy install.

It works great

I was excited to get this, because I used to have the countertop Waterdrop filter system and that was the best water filter I've ever owned. This thing, however, is...not.For one, it's very tough to maintain a seal between the filter in and the faucet. It doesn't tighten completely, so if I've accidentally knocked and rotated the position of device even a smidge while washing dishes etc, the next time I go to use it I get sprayed in the face. That especially sucks when I'm on my way out the door and just trying to fill my water bottle on the way out and now how to go change, redo my hair and/or makeup. I try to remember to neurotically tighten the seal before each time I use it to be safe, but when I've got other stuff on my mind, it doesn't happen.For another, the description says that the filers last 3mo. They absolutely do not. This filter began to cr*p out to an unusable level about 3 weeks in. How do I know? Well, that brings me to the third issue. As the filter is used and begins to become less effective, the flow rate gradually slows down...beyond its already very slow initial rate. I'm not sure what dolly's teacup they filled to be able to make the claim that "you can fill a cup in 6s," but it certainly wasn't an 8oz vessel. I didn't ever time it exactly, but I'd estimate that it took about a 45-60 seconds (not 12) to fill my 16oz water bottle at the *very* start. At the 1mo mark (1/3 of the claimed filter life), I was down to tiny drops of water coming through the filter when it's on. And yes I mean this--and everything else I've said-- 100% literally.After having both Pur and Brita faucet filters before and being annoyed with their huge size, I was stoked to be able to get one from Waterdrop. I believed all the description claims because I'd been so pleased with my other Waterdrop, but this thing seems designed solely to use lies to sell filters.Note: For reference, I live in a circa 1920s building in Manhattan NY. Water hardness is ~62 which is "moderately hard." Pure and Brita faucet filters had always lasted ~3mo for me when I lived in Albany NY which is a similar hardness. The Waterdrop counter filter I owned Iw as using in Las Vegas NV, where the water hardness was close to 300. Some of the hardest water in the country. I really did expect this to be an excellent product that could handle NYC water with ease.
