The media could not be loaded. Update (June 2025) It has been eight months, and the water flow has decreased considerably from 100% to 25%, despite its advertised two-year filtration capacity. Water flow is a significant factor. While it may be affected by Oklahoma City's water quality, I still find it worthwhile because it provides fresh water for drinking, cooking, washing dishes, and hands. Therefore, paying $5–$10 per month, depending on the filter's lifespan, remains a reasonable cost. Old review (Feb 2025) First of all I want to share that I live in Oklahoma city urban area to give a more specific views on the quality of water here. It has been 4 months since I installed the Waterdrop under sink water filter to improve the taste and quality of my tap water. Here's my experience with the installation, performance, and overall value of this system. Water Taste and Clarity: The filtered water tastes significantly better than my tap water, no smells. It's clear and the chlorine taste/odor/sediment has been greatly eliminated. Flow Rate: The water flow rate is good (reasonably slower than before installation) Filter Lifespan: I've been using the filter for 4 months and it's still performing well with no reduced flow rate compared to 4 months ago.

I have been using Brita pitcher and filters and wanted a more convenient filtration system that doesn't require frequent filter changes and is easy to install. I bought this system because it seems to include everything that I want and not too big or expensive. Unfortunately, my water outlet has a smaller diameter (1/4") than the one provided (3/8"). So I emailed their customer service to see if they can provide me an adaptor. They responded me within 24 hours and provided me with a link to purchase the part from Amazon and offered to refund me the cost for the adaptor. Sadly, the adaptor did not fit but I was able to find one on Amazon that does. I sent them the pictures and they refunded me as promised. I am really impress with their customer services. The filter system seems to work very well so far with great water pressure and the dedicated faucet looks really nice. Water also tastes better than before. Read more

This is the second Waterdrop under sink filter I have installed in the last week. I picked one up on Amazon to replace a leaking under sink filter for my in-laws last week and I liked it so much I bought one for my own house. We already have a basic whole house filter but I wanted the .01 micron ultrafiltration on the kitchen sink that we use for cooking and drinking. Super easy install. The product comes with an installation kit which includes supply lines with quick connects to the filter and 3/8 male and female compression fittings for the supply valve and faucet. The kit has some extra adapters and Teflon tape. I did not need any of the extras. The product is packaged very well and does come with instructions. You don't really need the instructions though. The instructions for the filter timer that mounts on top of the filter housing are on a separate self-adhesive label which you could attach to the inside of your sink cabinet or door. It explains the function of the single button on top of the filter. And apparently you will get a red blinking light and an audible reminder when the filter reaches the end of life. There is also an app which tracks the filter by serial number and can remind you when it's time to change the filter. Especially nice that it will track multiple filters. Changing the filter in the future is as simple as turning off the water supply, release the water pressure at the faucet, spin the filter one quarter turn to the left. Reverse the procedure for installation. Overall a great product and simple installation. Read more

Installation was easy and managed to get it all water tight in first try. Flow, at least initially, is better than expected. Love how easy the filter cartridge is to install and remove, just a quick twist. The water faucet is well made but the design could be improved. I wish the spout turned down more. If you have a small sink, the flow may hit the side rather than the bottom of the sink. The biggest drawback is the handle orientation of the faucet. I will never understand why the vertical position is OFF and the horizontal handle position (handle perpendicular to spout) is ON. It's a valve so why is it completely opposite to the convention used with shut-off valves, including the one provided? Read more

Was perfect for what we needed. Everything was in the box that was needed for install outside of a wrench (it isn’t stated that it’s included so it was ok) The install was fast and easy even with my old style pipes. The install looks clean and works amazing, the water takes about 3-5 mins of flushing but turns crystal clear and tastes delicious. Will absolutely buy again if I need another one. Read more

So far this filtration system is amazing. I did a water test before and after and the filter virtually remove removed all of the chlorine. Before the filter, I could not even smell or drink the water. It was disgusting.Due to the filter, my water is of springwater quality. The taste is now amazing. Connecting and setting up this water filter is very easy. Read more
