The Flow is World’s First Portable Solar-Powered Water Purifier And Sanitation System

One of the best ways to cope with COVID-19 quarantines has been to head outdoors. And one of the best items you can have on hand to stay hydrated (and provide clean water for hand washing) is the GoSun Flow, the world's first portable, solar-powered water purification and sanitation system. 

It's small enough to fit into a backpack, uses solar energy to filter 99.99% of pathogens from water, and can function as a portable handwashing station, warm shower, source of clean drinking water, and much more. 

Here's how it works. The Flow is powered by solar, with a panel integrated into the top of the carry case. The solar panel charges a 18.5-Wh power bank inside, which drives a pump capable of moving around one liter (34 oz) of liquid per minute. The pump moves untreated water through a three-stage cartridge filter which then feeds clean drinking water out the other side.

If solar intensity is too low to power the Flow with sunlight, the pump can be powered from alternative means via USB. 

GoSun CEO Patrick Sherwin described how important the Flow is at this moment.


“As the world tries to reopen after the beginning phase of COVID-19, we all want to make sure we are doing our part to maintain our health and sanitation. ‘Absolute compulsive hand washing’ has been recommended by Dr. Fauci, and the GoSun Flow provides an easy, convenient way to wash your hands with clean water anywhere and anytime.

More than simply a water purifier, the GoSun Flow serves as an entire kitchen sink. With available upgrades, it can also be converted into a full-on portable shower with clean, hot water. The all-in-one unit includes a faucet, pump, filter, power bank battery, and solar panels. If you have electricity on hand, it can also be powered by a USB outlet.

“As we all know, coronavirus is disrupting the world in a way that hasn’t happened in our lifetime. At this time of need, we’ve expanded our capabilities and accelerated the development of our portable water purification and sanitation system, the GoSun Flow,” says Sherwin.

In early May, the GoSun crew spent the afternoon testing its new water purification system by setting up a handwashing station on the street corner outside a local hardware store. 

“We believe that now is the time to work together, innovate, and create products that make the world cleaner and more resilient. Being able to function and adventure during the COVID-19 pandemic is becoming critical, so GoSun is working to help fuel our customers’ outings and keep them safe. Now, with a kitchen sink that fits in your backpack, you're able to have freshwater on-demand, when you are away from home,” says Sherwin.

The Flow is the latest product in GoSun’s full ecosystem of innovative, solar-powered cleantech products that include its line of solar-powered cookers, lighting, batteries, and coolers that allow people to improve their quality of life without requiring the use of fossil fuels or deforestation. 

Each GoSun Flow purchase results in two trees planted through the cleantech solar company’s partnership with Trees for the Future. So far, GoSun has helped plant over 40,000 trees.
