GreenOtter™ can supply up to 120 liters of pure drinking water per hour from any land water source (including brackish water up to 2,500 PPM).
Operated energy-independently (by simply rotating a manual handle), GreenOtter™ will protect against ANY chemical and biological contamination, including the most challenging toxins.

The unique ergonomic hands-free backpack design ensures comfortable carrying, simple field mobile servicing, and routine maintenance with no special tools, making it easy to care for and maximize the system's lifespan.

During disaster recovery, access to pure water becomes a critical issue. Water sources often get contaminated chemically or biologically due to drainage, infrastructure collapses, or floods. In such scenarios, clean drinking water becomes the topmost priority for humanitarian missions, survival planning, challenging trekking adventures, remote work sites, and many other situations. But, with the GreenOtter™, any questionable water source can be turned into safe drinking water quickly and easily.
