Features
- [After Sales Assistance] Waterdrop Backs the WD-10UA's high-end technical performance with a comprehensive prorated performance service; should a quality issue arise with the filter, you can contact us. 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.
- [Innovative Design] Only a cold-water source should be used to power the filter. 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.
- [Solve Clogging Problem] By upgrading the filtration area, our filter now provides a 20X increase in dirt adhesion area, enhancing filtration capability while minimizing the risk of clogging.
- [Filter Replacement and Long Lifespan] This system may be upgraded with a UF or a MZ filter to meet your water needs. It is compatible with several filters with various functions. 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.
- [Wide Application] The filtration system was created for residential and commercial usage, and it can be installed in your kitchen, bathroom, RV, or office to satisfy your daily water demands. This under sink water filter is the finest option for a leased property due to its stunning design and compact size. It is suitable for faucets with a FEMALE thread of 1/2" or 3/8". Please get in touch with us prior to making a purchase if a female threaded connector is required to connect to your faucet.
- [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.
- TDS is not a professional way to measure the water quality. Essential Minerals, Calcium, Potassium, Sodium, Magnesium...These essential minerals are dissolved solids, PPM will not be dropping if you test with a TDS meter. Waterdrop undersink water filtration system is keeping all those minerals, but removes elements that are harmful to your body. Note: The activated carbon is made from natural coconut shells.

I live in an apartment and wanted something more efficient than a refillable water filter system. I had been using a zerowater filter refillable pitcher type but the filters made the water taste almost sour after a couple of weeks and had to stop using it. This water filter seems to be of good quality and has made a difference in the taste. I have mine setup to work through the cold water side in my kitchen sink and it works beautifully. For 37$ or whatever it is far better and cheaper to use this than a water filter pitcher type alternative. Also it says the filter is good for a year?! Just buy it. You’ll be glad you did.

I've had multiple reverse osmosis filters and a few different in-sink and under-sink filters in my life. I like the RO stuff the best for flavor so far, but I'm always terrified that ridiculous amount of shark-bite 1/4 tubing on the cheaper RO setups is going to leak (and for good reason, they do tend to leak), and RO filters are more expensive to set up and maintain. This was easy peasy to set up and the replacement filters are cheap and easy too. We tried this one because of the value and the gallons rating on the filter. It works well, especially for the value, but I have a few tips to help you have the best experience. 1-When you install, you'll want to make sure you have the right tubes and lengths. If you don't know the different between the different types of threads (comp vs npt) and when to use or not use plumbers tape (NOT with NPT fittings), make sure to do your homework first (youtube, home depot, or similar is great) or hire a plumber so you don't have an expensive leak problem waiting to happen. 2-The 1/8" metal fittings that go into the filter housing need to be put in pretty firmly, then pulled on less firmly to ensure they are set tightly. If they pop out, they weren't in far enough. 3-We find that the first 5-15 seconds of water flow has more of a chlorine flavor after a few hundred gallons have gone through the filter. It's not super strong, but running the water about 15 seconds before filling up our water bottles makes a noticeable difference (almost no chlorine flavor. This is probably because we have our drinking water on its own separate faucet (this one, which works fine: Kablle Drinking Water Faucet, Reverse Osmosis Faucet, Water Filtration Faucet, Drinking Water Purifier Faucet, Matte Black, B10) and we don't put as many gallons through it every day as the product is designed to deal with. The instructions tell you to run the water so much every day to keep the filter in prime condition.

The product works exactly as advertised and feels like a solid, reliable under-sink water filter. Installation is generally straightforward, but in my case I had a 1/4” compression shut-off valve and faucet inlet, which made the setup a bit tricky. I reached out to Waterdrop customer support for guidance, and I’m really glad I did. Their support team is outstanding - Andrew, in particular, went above and beyond to help me figure out the correct setup. He was patient, knowledgeable, and took the time to answer all my questions thoroughly. Thanks to the great support, everything is now working perfectly. I truly appreciate the level of service I received. Overall, a great product backed by excellent customer care. I would definitely recommend it to a friend

Love. Love. Love. So easy to install, I’ve even swapped sinks a dew times. Filters are easy to replace. I’m extremely picky on how my water tastes, and this tastes fantastic. Zero complaints here.
