WaterdropTSU 0.01μm Ultra-Filtration Under Sink Water Filter System, 3-Stage Tankless Undersink Water Filtration with Faucet, Smart Panel, Does not Lower TDS (𝙉𝙊𝙏 𝙍𝙊), Drilling Required

Excellent water filter system. It was very easy to install. The filters are easy to change out and it alerts you when it is needed to change. The water flow is excellent not slow like some the other systems and it does not waste water like the Reverse Osmosis Systems. Water tastes good too.

Just got our unit and installed it which was super easy only took me like 20-30 minutes overall to get it done, after letting the unit run for its 10 minutes on first go to flush out all the sand and filter particles the water was crystal clear and the taste was great. I see allot of reviews here with people using PPM readers seeing the water is still high with numbers that’s because this is not a “reverse osmosis” filtering system it’s a “osmosis” filtering system which means it does. It change the TDS which would affect the parts per million (PPM) because it’s leaving all the minerals in the water. If you are looking for something the lower your PPM this is not the system for you because it’s leaving all the minerals in the water which is a good thing in most instances but you will want a reverse osmosis system to lower the PPM which removes everything from the water leaving you with strait up H2O to the best of it’s capability. Liking it so far we’ll see if I run into filter removal issues down the road that’s others have stated so far. Lol

Had installed this in a diff apt unit and decided to get one myself. I have been using the countertop Brita system for a couple years.. it worked fine but constantly having to refill the container became a hassle. I’m only one person and it needed refilling 2-3 times a day.The Waterdrop system’s water is delicious and has cleared much need counter space. I will have to replace 3 filters but that’s pretty standard.

this was very easy to install and get up and flowing. very good tasting water.

I was a little skeptical about purchasing such an expensive water filter for my kitchen sink, even on a limited deal for $30 off, but I had tried some of the single filters, and they didn’t seem to connect right, leaving water leaks, and the refrigerator dispenser doesn’t have enough flexibility while also being in front of the ice dispenser, which always makes me accidentally hit it. This was simple enough to install; however, the directions are super confusing so I suggest you watch a YouTube video on how to install it like I did. All you need to do is type “installation instructions for…. (Insert product name here)” on google and the manufacturer installation guide is the first video that pops up. It’s helpful to see how the rings are attached because the paper instructions are garbage with diagrams that don’t really label anything and only vague written instructions.This water filter also came equipped with everything you need for setup, minus the wrench. It even included a water diverter/tee for the cold water line pre-installed on the line and two sets of plumbers tape. My suggestion is that you tighten the valve/diverter right at the cold water line more than you think you need to as just the simple hand tightening and a quarter turn with the wrench won’t do it for this one and you’ll have leaks when you open the line back up. I already had a different faucet installed, but the connection for the outlet water seems to be universal and you don’t have to use the included faucet if you don’t want to. I couldn’t find just the water filtration system as a stand-alone item, so it seems to only come with the faucet. I don’t like that because it drives the price up for an extra item I don’t need, but I digress.After you install the filter, make sure to run it for a little bit to clear the line. If you try to grab a drink within the first few minutes of use, you’ll end up with charcoal in your water from the filters. I don’t know if it’s the faucet I used or the unit but the water pressure is actually pretty great coming out of the line and fills my water bottles up very quickly. It maybe takes 10 seconds to get 20 oz of water in my Stanley. It’s much quicker than our Whirlpool fridge dispenser and adjustable so you can move it to the precise location you need without taking the lids off your bottles. I see other reviews mentioning and showing videos of the PPE levels coming out of the filtered water, which are close to tap water, and this had me concerned. I did some research and this is not a reverse osmosis filter, so the minerals remain in the water, closely resembling tap. I didn’t want to go through all the hoopla of getting a reverse osmosis water filter because then you have water waste as well as needing an outlet to plug in the unit and drilling holes in the drain pipes for waste water. I have an outlet under the sink for our garbage disposal but everything else just seemed like sooooooooo much extra work. This unit was able to be set up in less than 10 minutes with the filter faucet already being installed. If I had to do that, it would have taken me maybe 5 more minutes. This unit is simple and efficient, with the water tasting much better than with the single filter or from the fridge.All in all, this is a pretty solid little water filtration system and I’m happy with it but only time will tell if it has longevity/durability. I’ll be sure to update my review should something go awry or the unit fails, but for now, it gets 4 stars from me.

Easy install, as described! Nice that it filters water yet doesn't strip minerals.

I’d been drinking bottled water for 2 months since moving into a new home & was sick of lugging bottles. So I bought this unit & had a professional plumber install. We let it run for 10 min, 3 times before drinking. It didn’t taste good. So the next day I again ran for 10 min 2x. Still tasted lousy. Like really bad.After drinking for a week, I got sick with digestive issues. So I bought a good quality meter to check bc it. It gave the same reading as my tap water! And I live in an area where tapwater is unsafe to drink! So this stupid machine was making me ill. I’m so angry at them for selling this piece of crap, which has been hazardous to my health!Besides the $150 for the machine & another $150 to have installed, I am out!As I’m unable to uninstall myself returning will cost me even more!!!!Shown is today’s PPL reading, after over a week of running it 10 min 2-3 dif times daily. I’ve never gotten a reading under 550!!! It’s always between 550 & 600 and about the same as the tap daily, so it’s doing NOTHING! It measure Crystal Gyser at 87. Distilled at 0, so the meter is accurate. Will get different water than Crystal Gyser too, as 87 is too high for bottled water.The glasses were clean each time I tested the water.

Put this in our RV, didn't take up too much space and have a clean water right at my sink. No water bottles, or water containers to clean the water or gallons of water around. Absolutely love the system.
