Whether you are traveling and want to make sure the tap water you are drinking is safe or simply just tastes better, or you are heading out on a solo adventure with plenty of water sources along the way, in-bottle filtration devices make it super easy to drink clean water on the go. Here are a couple new options available from LifeStraw and Katadyn.
The LifeStraw Go ($50) water bottle uses a two-stage filtration process which removes bacteria and protozoa to make microbiologically contaminated water safe to drink, while also reducing organic chemicals, chlorine and bad taste. Stage one is a hollow fiber membrane that removes 99.9999 percent of bacteria (E. coli and salmonella), 99.9 percent of protozoa (Giardia, Cryptosporidium, etc.), and reduces turbidity by filtering particulate matter larger than 0.2 microns. Stage two is an activated carbon capsule that reduces chlorine, organic chemical matter (like herbicides and pesticides), and bad taste. The hollow fiber membrane will filter up to 264 gallons throughout its life, while the carbon capsule will filter 26 gallons.
The new LifeStraw Go bottle weighs less than 8 ounces, holds 22 ounces of filtered water, and comes in five different colors.
Katadyn goes the soft bottle route with the BeFree ($40)–an integrated microfilter and flexible soft flask made from Mydrapak that can hold 0.6L of filtered water. The EZ-Clean Filter Membrane negates the necessity of backflushing, allowing you to simply shake or swish to easily clean the filter anytime. The filter safely removes up to 99.9999% of bacteria and protozoa using the new 0.1-micron EZ-Clean hollow-fiber filter, protecting you from harmful organisms such as Cryptosporidium, Giardia, E-Coli and Salmonella.
The BeFree filter offers easy drinking without sucking due to its unique Free Flowing Channel filter technology. As the smallest packable filter in the Katadyn lineup (read: 58 grams), the BeFree packs down to fit in your pocket, allowing you to smash, stash and go.
