LifeStraw Sip Filter Straw

The microfilter is designed to remove 99.999999% of bacteria and 99.999% of parasites, as well as microplastics, from your water. It uses a 0.2-micron pore size to physically block these contaminants.

While the LifeStraw Sip is highly effective at removing bacteria and parasites, it is primarily designed for travel, airport sinks, and questionable tap water. It is not intended to purify water contaminated with viruses or chemical pollutants, so it is best used in situations where the water source is generally clear but potentially biologically compromised.

After each use, blow air through the straw to clear out any remaining water. The stainless steel exterior can be wiped down with a damp cloth, and the protective carry case helps keep the mouthpiece clean between uses.

Not at all. The straw itself weighs just 1.8 ounces, and the entire kit with the carry case comes in at 3.1 ounces. At 10 inches long, it fits easily into most bags, purses, or even a jacket pocket.

The straw itself is made from premium stainless steel and silicone, which are neutral materials that do not impart a plastic or metallic taste to your water. However, it does not filter out dissolved minerals or chemicals that might affect the flavor of the water source itself.
