The LifeStraw Peak Series Membrane Replacement Filter lasts up to 2,000 liters (500 gallons). Once the filter reaches its capacity, water flow will stop, indicating it's time for a replacement. For those using the optional activated carbon filter, it should be replaced every 100 liters (26 gallons) to maintain optimal taste and odor reduction.

While the filter effectively removes bacteria, parasites, and microplastics, it does not remove viruses. Additionally, the filter does not desalinate water or remove dissolved chemicals unless paired with the optional activated carbon filter. Users should be aware of these limitations and consider additional treatment methods if necessary. For comprehensive water treatment options, explore our Survival Water Solutions article.

The filter is designed to stop water flow once it reaches its maximum capacity of 2,000 liters. This feature ensures you are not using an ineffective filter. If you notice a significant decrease in flow rate before reaching this limit, it may be due to clogging from high sediment levels, and backflushing might be necessary.

The filter should not be exposed to freezing temperatures while wet. Freezing can damage the microfilter, rendering it ineffective. If you expect freezing conditions, ensure the filter is dry before storage. For more tips on using water filters in varying conditions, see our Pillar 2: Water guide.

The optional activated carbon filter attachment improves water taste and odor. It reduces chlorine, chemicals, and heavy metals like lead and mercury. This is particularly useful in urban environments where chemical contamination is a concern. The carbon filter lasts up to 100 liters (26 gallons).

To store the filter, ensure it is completely dry to prevent mold and bacterial growth. Store it in a cool, dry place away from direct sunlight. If storing for an extended period, consider sealing it in a plastic bag to keep it clean. For more on maintaining your emergency gear, explore our Complete Guide to Emergency Preparedness Kits.
