How to Store the LifeStraw Home Filters

We recommend storing the membrane microfilter in a saline solution if you won’t be using the system for an extended period. This helps prevent mold or algae growth and keeps the membrane moist, ensuring a smoother restart when you're ready to use it again. If the membrane dries out completely, it can be difficult to restore proper flow.

Please follow the steps below:

1. Discard Water

Empty any remaining water from the pitcher or dispenser.

2. Remove Carbon Filter

Take out the carbon filter and let it air-dry for 30 minutes.

If storing for longer than two months, we recommend disposing of the used filter and replacing it with a new one when you're ready to use the system again.
If storing short-term, place the dry filter in a sealed, reusable container and store in a cool, dry place.

3. Remove Membrane Filter

Remove the membrane microfilter and rinse it under clean water.

4. Clean the Pitcher/Dispenser

Wash the pitcher body and filter housing with soap and water. Let dry completely before storing.

5. Disinfect the Membrane Filter

Mix ¼ teaspoon (1.25 ml) of household bleach with 2 cups (473 ml) of clean water.

Place the membrane filter in this solution for 10 minutes.
Remove and rinse thoroughly under clean water for 1 minute.

6. Soak in Salt Solution

Mix 1 teaspoon (5 ml) of salt in 2 cups (473 ml) of clean water until fully dissolved.

Immerse the membrane microfilter in this saline solution.
Store in a sealed container in a cool, dry place with the filter fully submerged.

7. Store Separately

Keep the membrane filter in the saline solution.
Store the dry carbon filter in a separate, sealed container.

8. Resume Use

When you're ready to use the system again:

Remove the membrane filter from the salt solution and rinse under clean water.
Reassemble the pitcher or dispenser with the filters.
Run two batches of water through the system and discard the first batch, as it may taste salty.
If stored longer than two months, use a new carbon filter.

Storing the membrane in saline helps prevent clogging from dried silt or sand and maintains filter integrity over time.
