  • Good filter - though hard to verify what they advertise
Color: White Size: 800 GPD
I installed the this Water System in my home and have been using it for 3+ months, and I must say, it has been a game-changer for our household's water quality. Let me break this down One of the standout features of this reverse osmosis system is the water flavor it delivers. The purification process leaves behind crisp and refreshing water and we can confidently say that it has elevated our drinking and cooking experience. The installation process was straightforward, though I did invited a certified plumber to get the job down. The user-friendly design of the interface makes daily operation hassle-free. It is difficult to gauge whether the LED screen is truly accurate, if it is, then it is doing a great job The sleek and modern design of the System seamlessly integrates into our kitchen, adding a touch of sophistication. The aesthetic appeal of the system is definitely a plus for homeowners who prioritize both functionality and design. Difficult to Verify the 1:3 Waste Water Ratio: While the system claims to maintain an impressive 1:3 waste water ratio, verifying this ratio has proven to be a bit challenging. and combine with one noticeable drawback is the occasional loud sound during the filtration process. While it's not a constant issue, there are times when the system generates more noise than expected. This might be a consideration for those with a preference for quieter appliances. However, the noise levels are generally manageable and do not outweigh the system's overall performance. In conclusion, the Residential Reverse Osmosis Water System has greatly improved the quality of our water, providing a refreshing and convenient solution for our household. ... show more

  • Easy Installation and Working Great
Color: White Size: 800 GPD
Our plumber complimented us on the ease of installation. 2 hours. Plus it cost a lot less to install. I am totally happy with the water drop unit as it fits under our sinks and has no tank to harbour bacteria. I am immunodeficient and can’t risk illness with a tank. We haven’t had any problems with it and hopefully no problems in the future. The water tastes great and the faucet with unit has a lighted display letting us know the quality of the water as it is being dispensed. ... show more

  • Best of the best - not loud at all
Color: White Size: 800 GPD
Expensive but worth every penny. Water comes out as fast or even slightly faster than the old fashioned tank osmosis filter we replaced. Nice to look at and easy to maintain. Water tastes crisp and crystal clean, even without a conditioning post filter. Very happy!

  • it's working perfect
Color: White Size: 800 GPD
installation menual is clear to understand. The size is bigger than I expected. No idea why flushing is often which makes noice when pump is owrking. I will figure out later. The machine is working well and the faucet looks nice with sense of hi-tech

  • Incredibly happy with Waterdrop RO system
Color: White Size: 800 GPD
I'd been relying on those pitcher-base water filters, but wanted to take the leap to an RO based system after moving into my new place this past summer. After doing a lot of research, I settled on the Waterdrop G3P800 system because it seemed to hit the sweet spot of great design and filtration performance (I own a number of products that have won the Red Dot Design Award and trust me, you will never regret owning a product that has won the Red Dot). So even though the jG3P800 was pricey, I reasoned the cost couldn't compare to being able to drink and cook with water that is free of not only common contaminants like lead, but newer, harder-to-filter stuff like PFAS "forever chemicals" that many filters won't catch. As such, the main points about why I chose the Waterdrop 800GPD are: * 800 gallons per day capacity * Efficiency (only 1 cup of waste water for every 3 cups of purified water) * Informative indicators on both smart faucet and main filtration unit (see pictures) * Easy-to-replace filters with indicators that let you know when you need to do so * Tankless, on-demand system (no need to worry about bacterial build up in tanks) * Integrated, in-line UV light to kill any bacteria that might have bypassed filtration * Extensive 9-stage filtration, including PFAS "forever chemicals" * Sleek, futuristic, integrated design that looks great both above and below countertop (and leaves plenty of space under) So it was to my great dismay that when my package arrived, I discovered the smart RO faucet was actually missing in the box! I immediately contacted Waterdrop support via Amazon.com, but in my anxiousness, I also ended up calling their toll free number. I was pleasantly surprised when someone actually answered the call in less than 5 minutes, as I was in a fairly sour mood given that a major component was missing on an expensive purchase. After explaining my situation, Waterdrop offered to send a replacement faucet out immediately. There was no back-and-forth—the agent on the phone just asked me to verify my shipping address and the missing part. Just two days later, I received a package with the smart RO faucet inside! The installation itself took a few hours (it helped that I already had a hole for the smart faucet pre-drilled into the countertop). I'm sure it would have gone faster had I had more experience with plumbing, but as long as you read the directions carefully and/or watch the installation videos, installing the RO system should be relatively straightforward. The most difficult part was drilling a 1/4" hole into the waste water pipe in order to connect the wastewater line from the Waterdrop filtration unit to. The best moment? When I plugged in the RO system to the under-counter power outlet and turned the 800 GPD on. It was lovely watching the displays light up and the RO system do its thing (you need to initially flush the system for 30 minutes, but the smart display on the faucet will let you know when the water is ready for drinking). I've now been using the Waterdrop RO system for almost 2 weeks now. I naturally use it for all drinking and cooking needs now, but given the extremely fast flow rate and the endurance of the 3 hefty filters, I am also using it to do a final rinse of all my dishes and flatware (I prefer to hand wash my dishes vs. running the dishwasher). I've also noticed my cats seem to love the taste and the purity of the water as well. In conclusion, I am completely delighted with my Waterdrop RO system. The hiccup with the missing smart faucet was annoying, but Waterdrop's responsive and helpful customer service really made up for the packaging oversight. Thus, without any reservations, I can heartily recommend the Waterdrop G3P800. ... show more

  • The unit works great and Customer Service is awesome!
Color: White Size: 800 GPD
We have used the Waterdrop G3P800 for just over a year and love it! Recently we changed filters. Easy! Our replacement CF filter caused the unit to increase noise levels a bit and slowed the water flow. We called customer service to see if this was normal, and they quickly identified the issue and sent us a new filter. Back to working like new! Highly recommend adding the remineralization filter. We are very happy with water quality, taste and support after the sale. This is WAY Better than our old tank system. ... show more
