GreenOtter™ can supply up to 120 liters of pure drinking water per hour from any water source on land (except seawater).
Operated electrically (standard rechargeable battery) or manually (simply by rotating the handle), GreenOtter™ will protect against any chemical and/or biological contamination, including the most challenging toxins such as Cyanide.

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.

In a time of disaster recovery, there is an immediate need for pure water. Water sources can become contaminated chemically or biologically due to drainage, infrastructure collapses, or floods.
Clean drinking water is one of the main priorities during humanitarian missions, survival pre-arrangements, challenging trekking adventures, remote work sites, and many other scenarios.
In all these situations and beyond, the GreenOtter™ will quickly and easily turn any questionable water source into safe drinking water.
