A three-pack of battery-free filter straws that you drink through directly from a lake, stream or bottle. Each straw uses a 5-stage hollow-fiber membrane rated at 0.1 microns, finer than the 0.2-micron pores common on rival straws, and is rated for up to 5,000 liters of water. At 2 ounces and 7 inches long, it drops into a bottle, cup or pack, and the removable ends let you clean it to stretch its life. It suits hikers, campers and emergency-kit builders who want a light backup filter; it is not a purifier, so it does not remove viruses or dissolved chemicals, and it needs clean-ish water to keep flowing.

This personal water filter straw lets you drink straight from a water source, like a normal straw. Just submerge it and drink. It needs no batteries and is BPA-free.
It uses a 5-stage filtration system with hollow-fiber ultrafiltration membranes and a 0.1-micron pore size. Under controlled test conditions, it has validated performance for bacteria and protozoa. It also reduces chlorine taste and odor and selected organic contaminants. Treat only for the contaminants listed in the independent test data.
Both ends are removable for cleaning. An extension tube attaches to the bottom for better reach, so you don't have to lean down to the water. Opening the bottom of the straw lets you screw it onto a water bottle by its threads. The straw is 7 inches long and weighs 2 ounces, so it fits in any bottle, cup, or glass.
