WaterdropG2P600 Reverse Osmosis System, 600 GPD Tankless RO Water Filter System, Under Sink RO System, 7 Stage Filtration, 2:1 Pure to Drain, Reduce TDS, FCC Listed, USA Tech

The unit is quite compact and effective. The installation is easy even for clumsy hands. The purified water tastes awesome. More importantly, they have amazing customer service. When we had some unknown frequent pump on/off issue, Rosie from the customer service helped us diagnose the problem step by step. Eventually Rosie shipped us a replacement unit without hassle. That truly resolved the issue and I deeply appreciate her help~

I took out an old tank based filtration system and replaced it with this WD-G2P600-W model. My old system fed a dedicated faucet as well as a refrigerator with water and ice dispenser. The old tank based system worked well but pressure would slowly drop once more than a cup of water was dispensed and it creates a lot of waste water to make pure filtered water. Plus replacing all the filters was a pain so I decided to get this unit because of the constant flow, ease of replacing filters and much less water waste.Installation was easy and water pressure to the old faucet was good but not to the refrigerator water dispenser. When dispensing water from the refrigerator, the water flow would be slow and pulsate. I checked the Waterdrop unit and the pump was turning on and off constantly even though I was holding the cup in the refrigerator dispenser requesting water.Turns out this system doesn't work well with the water filter in the refrigerator. I have a Samsung refrigerator so I purchased the Waterdrop Refrigerator Filter Bypass Accessory Kit for Samsung refrigerators...see image. This was the fix to the slow pulsating water flow problem. After replacing the regular filter in the fridge with the bypass filter, I now have a strong and constant flow from the refrigerator water dispenser. The icemaker in the fridge also makes ice normally, no issues. Another huge added benefit of the bypass filter is that I no longer have to buy water filters for the refrigerator!I did NOT have to replace the old faucet from my tank based system with the one that came with this unit. Tested with TDS meter and got 9ppm from immediate 1 ounce of water and 1 to 2 ppm after filling up a jug. Therefore as others have mentioned, you have to let the water run for a little bit in order to get the optimal filtration.The unit does make noise but I have it installed in the basement with water lines running up to the 1st floor kitchen. As such I don't ever hear the unit running and the water flow / pressure is stronger than the old tank based unit.

It's really a great product, and the water tastes amazing. Installation is easy, too. Initially, there was a leak in the unit, but Rosie from customer service helped with troubleshooting and then sent a replacement.

This water filter has truly made a positive impact on our lives.We incorporate it into our daily routine, eliminating the need for plastic bottles, and we prepare our meals with clean, filtered water.The filter effectively removes hard sediment and chemicals, which contributes to improved health and overall well-being.Furthermore, it is offered at a reasonable price. After a few months of use, it proves to be quite cost-effective.The installation process is relatively straightforward, provided one possesses basic hand tools. The majority of the required components are included, and they even provide a faucet.

There is lots to like about this RO unit for under the kitchen sink beginning with its compact, thin size. It fits nicely and still provides lots of room for storage. The biggest plus is the ease of filter positioning for replacement. 2 easy to remove filters that take all of a nano-second to swap out when the time comes. The faucet set that comes with the unit is also vey nice. Small, sleek and easy to operate. My water pressure is very good so I have good flow for the dog's drinking water. The water filtration also appears to be on point. It is virtually tasteless and has no odor vs our tap water which heavily smells of chlorine. Another big plus. The 4-star vs 5-star rating is the need for an electrical outlet to operate the unit. Most are without that need. I hired an electrician to place a plug specifically for this operation which is overhead. That said, once turned on, it is very quiet and the display is very straightforward. I followed the instructions to let the water run a solid 30 minutes prior to usage and that was about it for start up. Once the filters are needing replacement the visual display will flash alerting the need to swap out filters. The price was very economical, the unit appears to do what it is intended. If it were without the electrical component, it would have been a 5-star.
