Why is my LifeStraw not filtering?

If your LifeStraw is not filtering properly, it may be clogged or nearing the end of its lifespan. Regular use can lead to a buildup of contaminants within the filter, affecting water flow. Ensure you are using it within its recommended limits, as excessive use in dirty water can quickly diminish its effectiveness. Additionally, if it’s not cleaned after use or stored poorly, it might also lead to clogging or malfunction.

For example, if you've frequently used your LifeStraw in a muddy river, you might need to clean it more often.

**Pro Tip:** Blow back through the straw after each use to clear any debris and maintain optimal flow.

**Consideration:** If you've exhausted its lifespan of 1,000 liters, it’s time to replace it with a new one for continued safe drinking.
