What to do if LifeStraw freezes?

If your LifeStraw freezes, it’s important to thaw it gently before using it again. Extreme temperatures can damage the filter’s internal structure, so avoid direct heat like boiling water or placing it in a microwave. Instead, allow it to gradually come back to room temperature. After thawing, perform the blow-back cleaning technique to ensure that ice crystals haven’t compromised the filter's performance.

For example, if you've left your LifeStraw outside in freezing temperatures, simply bring it inside and let it warm up before using it.

**Pro Tip:** Store your LifeStraw indoors or in an insulated bag during winter adventures to prevent freezing.

**Consideration:** If you notice any unusual performance after thawing, it may be best to replace the LifeStraw to ensure safe drinking water.
