4. Setup
- Before first use, remove the LifeStraw Sip from its packaging.
- Remove the silicone caps from both ends of the straw.
- Submerge the filter end (the end with the small holes) in water for a few seconds to prime the filter. This helps water flow more easily.
- The filter is designed to be used directly in a water source or a glass of water.
5. Operating Instructions
- Locate a fresh water source (stream, river, lake, tap water). Do not use with saltwater.
- Place the filter end of the LifeStraw Sip into the water. Ensure the water level is above the filter end.
- Place the mouthpiece end into your mouth and sip slowly. The first few sips may require more effort as the filter draws water through.
- Continue sipping until your thirst is quenched.

6. Maintenance
- After each use, blow air through the mouthpiece to clear any remaining water from the filter. This helps prevent clogging and keeps the filter clean.
- Store the LifeStraw Sip in its leak-proof carry case to protect it from damage and contamination.
- The filter is designed to last up to 1,000 liters. Replace the straw when the flow rate significantly decreases or the filter reaches its capacity.
- Do not wash the filter with soap or harsh chemicals, as this can damage the filter membrane.

7. Troubleshooting
- Slow Water Flow: If water flow is slow, ensure the filter is properly primed by submerging it in water for a few seconds before use. Also, try blowing air through the mouthpiece to dislodge any trapped air or debris.
- No Water Flow: Check if the filter end is fully submerged in water. Ensure there are no blockages in the straw or mouthpiece.
- Unpleasant Taste: While the filter removes contaminants, some natural tastes from the water source may remain. If the taste is strong or unusual, consider finding an alternative water source.
