LifeStraw Sip Essential Straw (Seaglass) Filter Drinking Straw

The LifeStraw Sip Essential in Seaglass is a scientifically engineered, reusable filter straw that is incredibly light, weighing just 0.7 ounces (20 grams) . Its compact, BPA-free design is made for travel, outdoor adventures, and daily commutes, fitting easily into any bag or pocket .

At its core is a 0.2-micron membrane microfilter that removes 99.999999% of bacteria (like E. coli and Salmonella), 99.999% of parasites (such as Giardia and Cryptosporidium), and 99.999% of microplastics, as well as silt, sand, and cloudiness . It meets rigorous US EPA and NSF P231 standards for water safety, yet requires no batteries, chemicals, or complex setup .

The filter has a long lifespan, treating up to 1,000 liters (264 gallons) of water—enough for over a year of daily use . Maintenance is simple: blow air through the mouthpiece to backflush the filter after use, and periodically clean the silicone parts and caps . This product is not a purifier and does not remove viruses .

Every purchase supports LifeStraw's Give Back program, providing a year of safe water to a child in need, and the brand is a certified B Corp and Climate Neutral Certified .
