How to Set Up and Use

Setting up your system takes less than a minute. Follow these simple steps to start pumping clean water from any natural fresh water source:
  1. Connect the Intake Line: Attach one of the included silicone straws to the bottom intake port of the electric water filter unit.
  2. Drop into the Water Source: Drop the weighted pre-filter end of the intake straw directly into your river, lake, stream, or water container. Ensure the pre-filter is fully submerged.
  3. Connect the Discharge Line: Attach the second silicone straw to the top output nozzle of the device. Feed the open end of this straw directly into the included 27 oz TPU water pouch or your own clean canteen.
  4. Power On: Press the power button on the orange control panel. The internal electric pump will immediately activate and begin dispensing purified water. Press the button again to stop the flow.
  5. Emergency Manual Backup: If the battery runs low in dark conditions, unfold the integrated hand-crank dynamo on the side and rotate it smoothly to generate immediate, direct power to the filtration system.

Care and Maintenance Instructions

Proper upkeep keeps your unit operating at maximum efficiency and protects the lifespan of the advanced membranes.
  • Regular Filter Washing: The inner core filter is fully washable. After filtering turbid or muddy water, backflush or rinse the filter core with clean water to remove trapped sediment and restore optimal flow rates.
  • Battery Preservation: Recharge the unit fully via USB-C before storage. If storing long-term as part of a home disaster survival kit, recharge the internal battery once every six months using either USB or the solar panel to preserve overall battery health.
  • Dry Before Storage: Detach all silicone hoses and straws after use. Allow the interior filter housing and components to completely air-dry before sealing them in a bag or storage container to prevent mold or mildew growth.

Frequently Asked Questions (FAQs)

  • Can this system filter salt water or ocean water?
    No. This device is strictly designed for freshwater sources like rivers, streams, lakes, rainwater, and municipal supplies. It removes sediment, micro-particles, and odors, but it cannot desalinate saltwater.
  • How do I know when the filter core needs to be replaced?
    When the flow rate noticeably slows down even after thoroughly washing and cleaning the filter core, it indicates that the membranes are reaching total capacity and the core should be replaced.
  • Is the included TPU water pouch safe and durable?
    Yes. The accompanying 27 oz water pouch is built from ultra-durable, food-grade, leak-proof TPU material designed to resist punctures and abrasions while hiking or backpacking.
