How To Use
  1. Before First Use: Attach the filter to a clean water bottle, fill with clean water and squeeze to fully wet the internal membrane. Ensure steady flow before filtering untreated water.
  2. Squeeze Filtration: Fill your bottle with untreated water, attach the 28mm filter and squeeze. Drink directly or squeeze into another container.
  3. Gravity Setup: Connect the filter inline to a reservoir or water bag using the Plug-N-Play system. Hang above a clean bottle and let gravity filter the water.
  4. Drink-Through Setup: Install the filter inline between your reservoir and drink tube. Water filters automatically as you sip.
  5. Backflush to Restore Flow: Use the included backflush adapter with clean water to flush water backward through the filter. This helps maintain optimal flow rate.
  • Care Tip: Do not allow the filter to freeze when wet. After use, backflush, shake out excess water and air dry completely before storage.
  • Cleaning After Use: Backflush with clean water. Shake out excess water. Allow the filter to air dry completely before storage.
  • Storage: Store in a clean, dry place. Ensure filter is completely dry before long-term storage. If storing wet, disinfect first and dry thoroughly.
