A personal filter straw you put straight into a river, lake or puddle and drink through. It packs a seven-stage filter with a polyiodine resin stage that claims over 99.99% removal of bacteria and viruses, plus a nanosphere stage for lead, cadmium, chromium and arsenic. At under 90g it disappears into a pack, which makes it a backup to a pump or gravity filter rather than a replacement for camp water treatment. Owners of straw filters like this value the zero-setup, sip-as-you-go design; the trade-offs are a limited lifespan, no way to filter water for a group, and no protection against chemical spills or salt water.

Buyers of personal filter straws like this one praise the grab-and-go simplicity and light weight, and treat it as a pack essential. The recurring complaints are a short service life, awkward sipping from shallow water, and no signal for when the filter stops working.
This is a portable straw-type water purifier for outdoor use. It lets you drink directly from natural water such as rivers, lakes and rainwater by putting the straw into the water. The smallest size is about as thick as a pen.
The straw uses a seven-stage filtration system that combines filtration, deodorization, sterilization and seasoning. A prefilter removes sediment, silt, rust, algae, insects, dust and other particles. A contact sterilization medium, polyiodic resin, kills bacteria such as Escherichia coli and Staphylococcus aureus at a rate of over 99.99%. Activated carbon fiber reduces turbidity and removes bad taste and substances such as chlorine, trihalomethane and organic chemical pollutants.
A hydrophilic ultrafiltration membrane filters to 0.01 micron. Heavy metal nanospheres remove dissolved heavy metal ions such as lead, cadmium, chromium and arsenic. Only models A-2, B-2 and C-2 have the heavy metal function.
