Amazing solution for good water
Time will tell, but so far I’m thrilled with this filter! Affordable, compact, quick and easy install. This requires no electricity, no special equipment, and no dedicated faucet installed. Being able to have delicious water straight from my cold tap is a game changer. No more having water sit in plastic jugs, drive to refill, pay, and lug home. The initial cost is less than what I pay for refills, after a year the replacement filter will reduce the cost even more.

Great product!
My wife pulled up a video on how to set this up, but after that she said it was very easy to get through. The water tastes great now! I also like that it isn't bulky on the water faucet. I also appreciate that the water filter only needs to be replaced once a year. Would recommend this product.

Easy to Install, Great for the price!
Easy to install (10 minutes), great tasting water! It does use a battery, and I haven't checked to see what kind, or how easy it is to replace. I'm also a bit worried about lesser known companies - will I still be able to purchase a new filter in a year or so when I need one? As cheap as this product is though, even in a worst case scenario, its still very much worth it! Again, the water tastes absolutely great. We already had good tap water, according to our annual water reports - but this removes the micro plastics, the flouride, the chlorine, etc. I highly recommend

An actually certified water filter
We love this water filter. If youre someone who is looking for an actually certified water filter and wants something that feels as integrated and intuitive as possible this is the one. We tried Brita for several years and their plastic pitchers would always crack no matter how we would store them. We then thought maybe a sink attachment water filter would be a good idea. We then purchased a water filter from the brand Pur. It was literally the worst water filter we ever had. It would drip and drip. After hours of research of certifications (yes really hours) we decided on this one. We didnt like taking up counter space, we had wanted as close to an all in one as possible. Its installation was super easy and fast. The flow is soooo good. Its well made.

Great product, great service
Wonderfully packaged and easy to follow instructions. Durable and fit perfectly under my sink and installation was super easy. But the output hose that came with the filter didn’t have the correct fitting for my faucet. The instructions state if the hose doesn’t work to give their customer service a call. Becky was very responsive and worked diligently to resolve the problem I had. Becky immediately shipped a hose with a fitting that would work with my faucet. That did the trick and it works great with no leaking. I’m enjoying my filtered water.

Easy installation and an immediate improvement to my tap water
This filter is great. It immediately improves the quality of your tap water in taste, smell, and clarity to a huge degree. I live in a somewhat rural town that gets its water supply from a local lake, and the two times a year when it turns over, the water starts tasting and smelling really funky (almost like mold). This solves that problem completely! Installation is really easy - all it took was a drill, a crescent wrench, and some vice grips. It mounts cleanly to the cabinet wall below my kitchen sink and connected to my water line and faucet no problem with absolutely no leaks (no teflon tape required). Everything else you need is included in the box, even a little reminder button that's programmed to tell you when it needs a new filter. It's rated for about a year of use, but you could probably stretch it a little. From what I can tell, if you decide you want the filter to last a little longer, you can just swap out one of the bigger replacement filters since they all take the same adapter (I think). For that reason, I'd recommend installing it a little higher than you typically might in case you want to ever upgrade the filter size. After flushing it for 5 minutes, the cold water from my faucet started to come out clean and clear, with no discernible taste or smell. Huge upgrade! I use it exclusively for my drinking water, my ice maker, and even my morning tea tastes better. It is a bit big, but for something that's completely out of sight and lasts as long as it does, I don't have a problem with it. It's much less intrusive than an on-faucet filter or fridge pitcher, and you don't even have to think about it until the filter needs replaced once a year. It also will slightly reduce the water pressure from your cold line (I would say maybe 15%) so if you already have low pressure, that might be something to consider. That isn't a problem for my setup so I barely noticed it. Overall, I highly recommend this filter! For the price, you're getting clean, good-tasting water from your tap at all times with minimal maintenance and a simple installation process.

An Excellent Upgrade for Clean, Great-Tasting Water
I am incredibly impressed with my Waterdrop water filter. Since installing it, the improvement in water quality is noticeable immediately—it removes that harsh tap water taste and leaves everything crisp, clean, and refreshing. The installation process was straightforward and hassle-free, which I truly appreciate. It feels sturdy, well-designed, and gives me great peace of mind knowing that my family is drinking filtered water that is free from impurities. If you are looking for a reliable, efficient, and high-quality filtration system that actually delivers on its promises, I highly recommend this one. It is a fantastic value for the quality of water it provides!

Awesome
Awesome. The install is easy and straightforward with no plumbing experience. For anyone wondering - this filter works just fine on a well system. I see about 35-40psi, and this filter works fine with basically no perceptible reduction in flow. Mind you my well water is softened and pre-filtered. Water tastes amazing! Highly recommended

Much more affordable and convenient than a Brita! Why didn't I hear about this earlier?
Very happy to switch over to this from Brita filters! 1. Value - A standard Brita filter works for 40 gallons at ~$8 a filter. That's roughly 20 cents a gallon. - A Waterdrop filter works for 8000 gallons for ~$40 a filter. That's 0.5 cents a gallon. - That's 40x cheaper!!! 2. Convenience - No need to wait for the slow drip of a Brita filter; which usually gets slower as overtime - You only need to replace this filter once per year, rather than once a month (but with this filter, you'll end up using it for things besides drinking like hand washing and dish washing, so not a fair comparison; you'd need to replace a Brita way more often if you wanted to use it for everything) 3. Overall healthiness - Since this will be filtering your typical cold water you use for hand washing or dish washing, you'll also be getting clean water in these cases; further reducing the amount of unwanted chlorine and other chemicals and minerals you may be inadvertently ingesting My one concern is overall water pressure as time goes on; will the flow slow down once more gunk builds up? Given the stellar reviews I'm seeing on other listings though, I trust this won't be a concern. I'll update this review if anything changes over time!
