It is specifically designed for municipal tap water and can only be used with cold water sources. It is not suitable for well water or hot water.

Its twist-and-lock construction and push-to-connect fittings enable installation in three minutes, three second replacement, and safety-assuring integration. This filter comes with a 3/8" line that connects directly to US sinks' standard 3/8" feed water valves. The system is connected to 1/2" and 3/8" cold water pipes and faucets with the use of the 3/8"-1/2" convertor fitting.

Each system has a maximum service life of 12 months when used with municipal water, which is sufficient to cover the needs of an entire household. Before going on vacation, please Put the filters in separate sealed plastic bags, and store the bags in your refrigerator (NOT the freezer) to keep it fresh in 30 days.

- [Fast Flow Rate] The fast and stable water supply provides pure and fresh water that tastes like spring water. The tested full flow rate is 0.75 gpm at 60 psi. Its upgraded 3/8" outlet ensures a fast flow rate of 1.33 GPM, maintaining efficient water flow and preventing blockages for long-term usability.
- [Multiple Uses] Developed for household and commercial use, the Under Sink Water Filter System can be installed in your kitchen, bathroom, RV, or office to meet your daily water needs. Ideal for drinking, cooking, skincare, and cleaning.

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.

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!

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

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.

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.

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.

If you want a water filter to help remove the chlorine smell and taste from city water, this filter is the one to get! I was buying upwards of 15 gallons of spring water a month (for just me 😳) so I checked into different types of water filters. When I came across under the sink filters, I decided to try this one and it does not disappoint!!! No, as someone else mentioned, it does not give you the clean, crisp taste of spring water, BUT, in just a few days I’m drinking this water with absolutely no problem and loving it! Someone else mentioned a diminished water flow. That is not the case for me. This filter has not affected my water flow at all. Someone mentioned leaks, I’ve had no leaks. I had a friend install it for me. With just a quick glance at the instructions, he had it installed in no time. He said the instructions were straight forward and he appreciated the little template to align the screws 👍. I’m so excited that after 9 years of buying bottled water, I have great tasting, good quality water flowing from the cold water tap of the kitchen sink. One quick side note you might want to consider… my friend installed the filter at the front right side under the sink “so it would be easy for me to access when I needed to change the filter” 😱. He’s so smart! But does he really think I’m going to change my own filter 🤔? LOL, of course I will, and I’ve gotten a bit silly but that’s how excited I am about the taste of the water from this filter. It truly does everything it says it does!
