Great filter to easily improve your water quality.
This product comes with everything to install as a main filter or on a single line. IF you bought a water filter faucet to be installed in addition to the original OR you purchased a Kitchen Faucet WITH Water Filter Faucet, you will need to buy an additional splitter for the cold-water supply valve. Really good choice if you live in a apartment or rental property. Not a install and better than using a pitcher for drinking water. The price and ease of installation makes it easy to remove and take it with you for the next place. The filter is thin and a little tall but fits nicely under the sink. The part that you mount, where the filter installs to, has the ability to lift up and be removed as a complete unit before taking the filter off. That helps to have something under it to catch water when you remove the filter. I purchased a pressure gauge to see when the filter is getting to the end of its life. Ad says 2 years of use, MAX. That depends on many factors but the two easiest is water Use and Quality. Water quality can greatly reduce the life. If you have a well or if the municipality has sediments, mineral deposits, and "other", the life will be far less. If you have the filter in line with the main faucet and dishwasher, more water flow, the more water used, the more the filter is catching. The 10UA is good for 11000 Gallons. The 15UA is good for 19000 Gallons. You can look up water usage on USGS. Can you buy the 10UA and upgrade the filter to 15UA later, yes. The mounts are the same. Water quality is really good; Price point is great; Filter replacement cost is budget friendly.

Quality and “bang for your buck”
I purchased this product based on reviews found online on consumer sites. This unit is intended for under the sink installation but i did not realize this when i ordered it. The unit comes with 1/2 inch and 3/8 inch supply lines which are pretty standard for the manufacturer intended use and installation. I feel no need to filter all tap water for washing dishes and such and wanted to use it for the water dispenser and ice maker built in to the fridge. My intention was to use it as a replacement for my GE refrigerator inside filter which as many others customers will testify is very expensive to replace due its relatively short lifespan (less than 3 months) even in a a two person household. A call to GE and they provided me with a bypass device to replace the onboard filter so i could install an exterior unit as many have done to great satisfaction. I contacted Waterdrop customer service and agent Karina was very helpful in trying to find me a suitable adaptor for the size difference of my refrigerator connections but we had both come up with the same problem. The needed parts were not available on Amazon so in conclusion we both agreed a visit to plumbing supply would be most appropriate. The parts i needed cost me $12. No problem, for me this was an easy fix and the filter works 1000x better than the onboard OEM unit that GE puts in their fridge. Even when new it would take like 20-30 seconds to fill a glass of water and now its like 5 seconds. Filling a pot of water to cook with went from maybe over 2 minutes to under a minute. Totally satisfied at this point i was surprised with a follow-up from Waterdrop and a short conversation led to an offer for a reimbursement of the cost for buying the extra parts i had purchased. In my opinion this is what i would call OUTSTANDING CUSTOMER SERVICE ! I will certainly update this review accordingly if the unit falls short of its advertised expectations.

Filtration made easy and delicious
Makes tap water taste like expensive water bottles. AMAZING ! Installation is easy I had a harder time cleaning under the sink.( I have a spray bottle for EVERYTHING ) OMG. Filtration, yeah easy snap in o ring plugs make a positive connect and the 3/8 standard fitting in and out . I used 3/4 wood screws so it wouldn’t penetrate into the other cabinet for the holder . If you want hot water to be filtered as well you would need one of these kits for your hot side

Good water filter, more cost efficient
Easy installation. Universal fit. Water isn’t as tasty as distilled but it does remove bad aftertaste from tap water.

This thing makes staying hydrated way less of a hassle
Drinking water goes from an annoying hassle with water filter pitchers and dispensers which have to be moved around, cleaned, and refilled, lest they harbor mold and bacteria. If you have trouble staying hydrated because it is a hassle this unit is a great solution, especially if you are renting as you can't use normal under sink filters that require drilling holes. This filter is different, you just hook it up to your regular faucet. Even if this unit only lasted 6 months out of the year I would happily replace it because it makes drinking water that doesn't taste disgusting so much less of a hassle. (It of course doesn't reduce TDS but you don't really want that for most uses, unless you have special water filtration needs or have issues with water scale ruining your coffee makers, but RO purifiers actually have to add minerals back otherwise the water will taste funny.) The unit feels solid and had no problems with installation. It comes with adapters for most under sink hoses and teflon tape (although you likely won't need it since they have a rubber gasket for sealing). The filtering speed is fine, it doesn't noticeably reduce water flow (at least when new, will update if that changes), although the sink used has the smaller hose size. It's unlikely size will be an issue unless your under sink space is tiny.

Easy peasy nice and easy!
Easy install. In a rental so I did not have to mount to wall. Just tucked all the way in the back and it’s standing fine on its own. No significant change in water pressure. Water seems to taste fine. Peace of mine provided although no formal water testing.
