LifeStraw Peak Series Water Filter System

The system is re-engineered to maintain a consistent flow rate even in challenging conditions. While it effectively filters out silt and sand, you should still try to source the clearest water possible to extend the life of your filter.

It is highly versatile. You can use it as a gravity system by hanging the reservoir, squeeze it to filter water into a separate bottle, or drink directly from the source using the filter as a straw.

The filter will stop allowing water to flow through it once it reaches the end of its 2,000-liter capacity. At that point, the pores in the membrane are fully blocked, signaling it is time for a replacement.

Yes, it is designed to be backwashed. Keeping the filter clean is simple and helps maintain a strong flow rate throughout your trip, especially if you are filtering water with high sediment.

No. The membrane microfilter removes bacteria, parasites, and microplastics, but it does not remove viruses. If you are traveling in areas where viruses are a concern, you would need to pair this with a chemical purifier or use a different system.

The entire system weighs 8.1 ounces. It is designed to be compact and lightweight, making it an easy addition to your pack without adding significant bulk.
