LifeStraw Peak | What should I do if my LifeStraw Peak System becomes clogged?Updated 2 hours ago

Which products does this apply to?

This guidance applies to the LifeStraw Peak Series Straw, Peak Solo, Peak Squeeze, and Peak Gravity systems. It does not apply to the Peak Gravity Purifier.

Why is my filter flowing slowly?

Slow flow is usually caused by debris buildup, trapped air, or a filter that needs cleaning. Regular maintenance helps keep water flowing properly.

What should I do if my filter is clogged or flowing slowly?

For Peak Solo, Peak Squeeze, and Peak Gravity systems, we recommend backwashing the membrane microfilter with clean water using the included syringe. This helps remove debris from inside the filter.

How do I backwash the filter?

Disconnect the membrane microfilter from the cap, attach the backwash syringe, draw clean water into the filter, and push it back through several times.

How often should I backwash?

We recommend backwashing regularly after use to help prevent clogging and maintain flow.

What if backwashing does not help?

You can disinfect the filter by using a solution of 1/4 teaspoon of household bleach mixed with 2 cups of water. Flush the solution through the filter with the syringe, then rinse thoroughly with clean water.

What if the filter dried out?

If the filter has dried out, soak it in a saline solution made with 1 teaspoon of salt and 2 cups of water. Store it in an airtight container for 24 hours, then backwash with clean water before using again.

Why is my Peak Squeeze slower when using the carbon filter?

A slower flow rate is normal when using the carbon filter attachment because it adds a second stage of filtration to improve taste and reduce chemicals.

What is different about the Peak Straw?

The Peak Straw does not use the syringe backwash method in the same way. To help maintain flow, blow air back through the mouthpiece after drinking. If needed, let the straw sit in water briefly to help rehydrate the membrane.

When should I replace my filter?

If you have backwashed, cleaned, and rehydrated the filter and flow still does not improve, the filter may need to be replaced.

Still need help?

If your filter is still not performing as expected, please contact LifeStraw Customer Care. We are happy to help troubleshoot further.
