What is the “Portable Water Treatment Plant” GS-2811?

The Greeshow GS-2811 is a multi-functional electric water purifier designed for scenarios ranging from disaster-related water outages to mountaineering, camping, car camping, and fishing. It can purify river water, rainwater, and mountain stream water into safe drinking water with a single touch, developed under the concept of "ensuring safe drinking water anytime, anywhere."

Superior Filtration: Equipped with a 0.01μm High-Performance Filter

The GS-2811 adopts a "5-stage water purification system" combining a 0.01-micron ultra-high-quality hollow fiber membrane, PP cotton, KDF, and high-quality activated carbon. It removes 99.9999% of E. coli, microorganisms, red rust, and impurities while retaining minerals for great-tasting water. It has passed the Ministry of Health, Labour and Welfare water quality standards test and international SGS inspections, and is certified as a recommended product by the Disaster Prevention Safety Association.

"3-Way Power Supply" for Power Outages

Supporting USB Type-C charging, solar charging, and manual crank generation, it enables water purification even during power outages or isolation. Approximately 5 minutes of hand cranking provides 500ml of drinking water, making it a reliable "last resort."

Approximately 230L of Purification on a Full Charge

Equipped with a 3000mAh large-capacity battery, a full charge allows for approximately 230L of water purification. It also includes an emergency power supply function for smartphones to support information gathering and communication during disasters.
