Our municipal tap water here in Arizona has a strong mineral and chlorine bite. Installed the Waterdrop G3P600 Tankless Reverse Osmosis System under our kitchen sink in about an hour and a half. The quick-connect fittings made plumbing straightforward with zero leaks. Flow rate from the dedicated faucet is strong and fills a large glass in seconds. Tea, coffee, and ice taste completely pure now.
Replaced an old bulky tank system with this Waterdrop G3P600 Tankless Reverse Osmosis System. Having full access to our cleaning supplies under the sink again is fantastic. The real-time filter life indicator is very convenient, and the water tastes noticeably crisper than standard pitcher filters.
Arrived in double-boxed commercial packaging with all adapters and color-coded tubing included. Hooked it to both the sink faucet and our refrigerator ice maker. Ice cubes are crystal clear and there is no plastic aftertaste.

Yes. Because it uses an internal booster pump to provide fast tankless 600 GPD flow, it plugs into a standard 110V/120V household outlet under your sink.
The faucet features a circular digital screen at its base that continuously measures and displays the TDS (Total Dissolved Solids) in real time while water is flowing, plus a ring indicator that changes color when a filter change is due.
Filter changes take literally 3 seconds. The front magnetic panel pulls off, and the filters twist out and click back in like a lightbulb. You do not even have to turn off the water supply.
Yes. You can tee off the filtered water line to feed your refrigerator dispenser and ice maker using 1/4" PE tubing.
