Filtered Water, Wherever You Are

Once clean drinking water is not easy to access, every backup plan starts to matter. This portable water filter straw uses 0.01 micron filtration and an activated carbon stage to help reduce bacteria, protozoa, sediment, chlorine taste and odor from freshwater sources.

Use it straight from a stream, screw it onto a bottle or hang it for gravity filtering, so your family can make practical water decisions during outages, travel and outdoor emergencies.

    Water filter questions? Here are the answers.

    Yes. It is designed for freshwater sources such as creeks, lakes, rivers, rain tanks and tap water under boil notices. It is not intended for saltwater.

    The two-stage design helps reduce bacteria, protozoa, sediment, chlorine taste and odor-causing organic compounds. It is not rated for viruses, saltwater or dissolved heavy metals.

    Place the intake end in freshwater and drink through the mouthpiece. You can also attach it to a standard bottle or hang it above a clean container for gravity filtering.

    After use, blow gently back through the mouthpiece to clear trapped sediment, cap both ends and store it dry in your kit until the next use.

    Your order is covered by a 365-day return promise. Contact support within the return window and the team will guide you through the next steps.
