Why isn't my LifeStraw filtering water?

If your LifeStraw isn't filtering water, it could be due to a blockage or damage to the filter. This issue may occur if you are using it in very dirty water, which can clog the filter quickly. First, check the filter for any visible signs of damage or debris. If you find none, the filter may just need to be backflushed to clear out any blockages.

To backflush the LifeStraw, simply fill a clean container with safe water, insert the straw, and suck the water through it forcefully. This action can help dislodge any contaminants caught in the filter. If the flow rate is still low, it may be time to replace the filter as it may have reached its capacity.

For example, using the LifeStraw in a river full of silt could clog it faster than in a clear lake.

Pro Tip: Always carry extra water purification tablets in case your filter becomes unusable while outdoors.

Consideration: If you’re frequently using it in sediment-heavy water, you may want to pre-filter the water using a cloth.
