Waterdrop G2 Reverse Osmosis System, 7 Stage Tankless RO Water Filter System, Under Sink Water Filtration System, 400 GPD, 1:1 Pure to Drain, Reduces TDS, FCC Listed, USA Tech, WD-G2-W

I've been using this for about 4 months and I have to say it is a LIFE SAVER! We live in super low humidity and I was using 3 humidifiers 24/7 and there was this fine white dust EVERYWHERE. It took me about 6 months to figure out what was going on. Obviously buying distilled water for 3 6-gallon humidifiers would be prohibitively expensive. I bought this unit for one of our sinks and a different unit for another sink. I have to say I really like this one a ton better. The other unit utilizes a pressure tank so you can only get a little over a gallon every 30 minutes or so. Not a big deal if you are only drinking, but THIS unit is powered by a pump and you can fill up a humidifier in no time.I keep waiting for the "change filter" lights to go on, but they haven't. I am wondering if the fact that we had power cut offs in the last 4 months has somehow re-set the filter? It's hard to believe it is still functional with the amount of water we've used, but then there is no white dust coming from the humidifiers so I'm assuming it is still chugging away.This is well worth the money. I had a plumber set it up just because I didn't want to mess with it myself, but I can see how it would be a straight forward install for a handy person. Just make sure you have a plug in nearby as the unit does require electricity.Definitely recommend and would buy again!

We have had this for a few years now. I just got off the phone with support for an issue i had, since i was looking at my purchase information I figured id circle back and give it a review.This water filter system is a must have.My wife is european and can't stand the taste of the fluoride/chlorine in the water. this filter system does seem to do the job. We did go with having the additional remineralization filter by the same company in line with it to add back in minerals to also aid with the nutrition aspects.I rigged it up in my RV and we fill up water jugs for the house. i might plumb in a hookup so we have an extra tap in the main house when we are not traveling.The reason we had to call support line was a self inflicted issue(we did get a person in less than a minute).The issue was that my wife started filling a jug and walked away, only to return an hour later to a non functioning unit.The Unit goes into self preservation mode. filter lights flashing and the electric bolt not lit. Reset button does nothing.unplugging it and plugging it in is all you need to do...... however you need it unplugged for a full 5 minutes to ensure the capacitors/LEDS have completely dissipated to a fully off state.im impressed that it has the smarts to protect the motor and/or the house from potential water damage. I wish that was better outlined in the manual and would have saved me a call but in the end i'm always impressed with how well this little unit performs.

The G2 RO drinking water system did not meet my expectations. After several attempts to fix the problem—including multiple calls to customer service, changing filters, and flushing the system—I was very upset and ready to switch to a system from another manufacturer. Fortunately, I reached out again and was assisted by a very helpful representative named Krystal. She took the time to understand the issue and helped resolve it by offering an upgraded system (G3P600) for an additional charge. Once the new system arrived and was installed, I was pleased to see that it worked great—better than I expected. Now, I can confidently say my family is enjoying the best drinking water we’ve ever had.

The water filtration brought my tds and other factors down significantly, 400s to single digits like 5-9. The installation was easy, the three way does reduce sink water pressure i experienced prior to running a dedicated line. The taste is nice, nothing off putting. Flushed 5 gallons or so through prior to use. The machine does make a hum, or operational sound which may be annoying if it isn’t under the sink with a closed cabinet door. The machine does have a start lag, due to the pump needing to prime or pressurize itself. And the machines flow is a bit slower than expected, but for the sale price of $150 I couldn’t be more happier. 10/10 currently would buy again.

Great filter and can't complain much about water quality as it is capable of purity less than 30 PPM with my city water supply at the RV park where it is used. HOWEVER, it is limited to having to be run at least 1 quart of water through the system EVERY TIME I get water from it. The past several days I tested the purity and it will be as high as 165 PPM until the system is flushed. It is probably due to the tankless design, but it is not noted anywhere in the product literature that it need to be flushed. If you expect to have the purest water then you need to run at least a quart 32oz through before collecting any.

The package comes with a fairly complete installation kits that fit standard water supply lines. The installation challenge was mainly came from tight space under the sink. Initial flush took about 25min, it removed all taste from our city water line, which is the primary reason of having it. I like the water better than any bottle water I had.
