  • Well Designed, East to Install, Great Tasting Water
We live by the sea in an old community in an area with very high particulates in the water system. The water also smells like chlorine. We have always bought bottled water, but with the Pandemic, our grocery load started to become unmanageable as we cut down on the number of trips we made to the store. We started to drink the tap water and almost immediately decided it was time to try out a water filter. RESEARCH I did a lot of investigation, and by a long shot, the WaterDrop products represent the best designs on the market: - the forward-facing filters are as easy to replace as a refrigerator filter. - the tankless design means you don't lose much undersink space (Image1) - the tankless design also means there's no opportunity for bacteria to grow in the holding tank - the smart faucet (the led ring around the base) conveys the state of the filters - blue is good, yellow means you're due for a change and red means you should change a filter immediately - the WD-G3 display not only tells you the state of the water in Total Dissolved Solids (TDS), but also shows you the state of each of the filters (blue/yellow/red) so you know which one to order. - the brushed nickel finish matches our faucet and looks great (Image 1) - the 12 second time-to-fill an 8 oz glass is good Everything about this unit screams "quality". The instructions are simple and easy to follow. The 800 number is listed on the cover of the installation guide. Each part feels solid and well-made. INSTALLATION There is one challenge that most homeowners will probably face to using this unit -- it requires power under the sink. I had a socket under my sink that the garbage disposal was plugged into. I assumed (you can see where this is going!) that as is traditional, the upper socket was wired to the disposal switch and the lower was always hot. Unfortunately, living in an older home, this was not the case, so I had to replace the socket with a split/switched/always hot one. Our garbage disposal unit is huge, and our sink is in the corner of the kitches with one small door, so it needed to be removed to facilitate the install. Between the disposal deinstall/reinstall and and the rewiring job, installation took me all day. HOWEVER - The actual installation of the Waterdrop unit was approximately 40 minutes of this, so plan accordingly. I had one minor issue with the waste pipe connection, which is designed for 1.5" pipe (we have 2" pipes, but the pipe coming out of the garbage disposal was 1.5" with just enough space to connect the waste line). All of the lines are thoughtfully unique - there are two white lines, but of different sizes (one goes from the water source, one goes to the spigot) and the waste water is red, so you can't get confused. The connections are all pretty easy, although you should pay attention to the "Push the locking ring" instructions so you don't accidentally break one of the shipping plugs when removing them. The locking ring collars are a bit fussy and require a needle nose pliers to install. Other than my own personal challenges of a small under-sink space and the electrical issue, the installation was a breeze. WATER QUALITY So, the big question -- does it work? The answer is YES! See the second the image. I used an independent water meter to measure the TDS. On a sample from a bathroom spigot I got 99. This is pretty typical, we run around 90 to 120. Measuring the water from the filtering system shows 12. The reading on the front of the unit showed in the mid 70's during startup, but now shows 5. Given the somewhat wonky nature of water testing, I'm good with these numbers even though they differ slightly. The WD-G3 reduced the TDS in our water by an order of magnitude. This is exactly what you would expect from an RO system that should filter out about 90% of all TDS. This translates to a better tasting, safer glass of water, which it produces in about 12 seconds (8 oz). Not only does the water taste better, our coffee and anything else we used water in also tastes better. While the difference is not as evident at room temperature, you can really tell the difference in a side-to-side test of chilled water. We tested tap vs filtered vs Poland Spring bottled. At room temperature, they are all pretty much the same, with Poland Spring being slightly saltier. We tested the TDS on Poland Spring and it was at 41, confirming that there's some mineralization going on there. In chilled form, the filtered tasted the best, with Poland spring second and the unfiltered third. (And yes, to answer your question, my wife is now laughing at me because of my obsession with metrics and blind taste tests) FILTER REPLACEMENT/CUSTOMER SERVICE As some other reviewers have notes, the "CF" filter seems to be in very short supply and cannot even be purchased on the Waterdrop site. I contacted Waterdrop customer service who responded (on a weekend!) that the filters will be back in stock at the end of this month. SUMMARY Pros: - Does what it says, reduces TDS by a factor of 9-10 - Produces clear, clean water - Interface is intelligent and intuitive - Tankless design saves space and eliminates post-filter bacteria issues - Looks great - Responsive customer service Cons: - Requires un-switched power under the sink - The CF Filter replacement is currently unavailable. Recommendation: The CF shortage is worrying, hopefully Waterdrop will be able to solve this issue. It's a Pandemic so I'm willing to give them some leeway in supply chain challenges. I decided to take the plunge anyway and given the alternatives, this is still the best unit on the market. ... show more

  • overall pretty satisfied
the device is much bigger than I thought, so space saving probably not that much comparing with tack ones. I actually like this because this makes me feel more confidence about the quality of the product, I was a little suspicious when I placed the order as I thought the device is not that big. I have used the ones with tack for quite sometime, every time changing filter is not that easy, for this one, I am really impressed about the filter installation, I am sure it would a super easy one. every thing is well designed especially for easy installation including the faucet, so highly recommended. great product so far! ... show more

  • Much Better Than Tank RO Filter But Buy the Remineralization Filter
1. Pretty simple to install. 2. Takes up WAAAAY less space than a tank RO filter, which I had before. 3. It's quiet. I don't know what some people are talking about when they say it's loud. You can barely hear it and it only runs when you are dispensing water. 4. Taste was off and stayed in my mouth for hours after drinking, so I bought the remineralization filter and it made a big difference. I'm not going to say something stupid like "it's the best water I've ever tasted" but it now tastes fine. And somehow adding "taste" minerals back to the water made the TDS level drop from around 30 to under 20. 5. No mechanical problems after almost a month so if this things lasts 5+ years I'll be happy with the purchase. ... show more

  • Simply the BEST water filter system.
We have been using water filtration system for over 16 years. We decided to switch over to the Waterdrop system and we are completely happy with the unit and performance. We get consistent and direct water without having to wait for the filtered water to gather like most other system I have been used to. The unit is simple to install and use. It took me about 10 minutes to install the unit. What I love about this product is that it provides great taste and they offer unheard of superb customer service. I had an issue with a pump noise and their exceptional support team took me through every step of the way and even replaced with a brand new unit just to make sure I was completely satisfied. I would like to give a big thanks to Harper and Jessica for their exceptional customer service. I highly recommend this product to anyone thinking about a water filtration system for their home or business. ... show more

  • I like the water
I used to buy expensive water bottle delivery services and paid over $130/month. This RO system replaced my bottle delivery service. The water tastes good, and I don't really feel different compared with the bottled water.

  • Great First Impressions
Easy install :within 1 hr max. Love the design; tall yet slim as to not take up too much space under sink. I appreciate the very detailed instructions with many pictures. Don’t have an independent TDS monitor but we have very hard water where we live New Mexico. Not sure what TDS is on the fridge water after it’s filtered but it still tastes impure. Although still better than faucet water. After installing the RO system we are reading 47-50 ppm. This is after flushing system for 45 minutes. Also had same results within first 1-2 hrs of use. Was hoping for less than 50ppm but will give it some time after usage for a while. So far I’d highly recommend. ... show more
