Cold, clear water - The LifeStraw Water Filter Bottle

  Newsletter Article

In Germany, clean drinking water comes from the tap. Of course that doesn’t help when you're out hiking or backpacking. Water taps out in the middle of nowhere are statistically quite rare. Even when that mountain stream tempts you with its brilliant, crystal-clear, cold water, you cannot be sure that there isn’t a dead animal rotting in it fifty meters upstream, thus contaminating it. Backpackers in foreign countries or tourists in countries where the tap water does not completely meet German drinking water directives are faced with the same problem.

Luckily, humans are making progress not only in the smartphone industry, which makes it possible to integrate a camera into a smartphone housing, thus competing with the single-lens reflex cameras, but also when it comes to the outdoors. Now, backpackers and hikers will no longer have to carry around bulky water filtration systems. The “Lifestraw” water filter holds 0.64 liter and works with a 0.2 nanometer hollow fiber membrane. It was originally developed for use in crisis regions and now that it has been tested, it has proven useful for backpackers and tourists.


According to a lab report from the University of Arizona in 2010, “Lifestraw” filters out 99.9 percent of the bacteria and protozoans contained in water – and of course dirt particles and turbidities. Coli bacteria, salmonella and parasites get trapped in the filter instead of entering your digestive tract. In the second stage, the active carbon capsule also bonds certain chemicals, pesticides and feces. The bottle is made of food-safe, BPA-free (bisphenol A) tritan plastic and its cartridge filters up to 1,000 liters.


Aside from these impressive values, there is another benefit to purchasing a “Lifestraw” bottle. According to the manufacturer, when you buy a Lifestraw bottle, the company will donate a one-year supply of clean drinking water to a school child in a developing country. Cheers!
