Performance: The LifeStraw is a multi-purpose personal water filter perfect for the great outdoors or even in case of emergencies. It features a high flow rate and weighs only 2 ounces. It requires no chemicals or batteries and has a life span of 1,000 liters (264 gallons). LifeStraw meets EPA standards for water filtration and has been used around the world under extreme conditions for humanitarian relief, making this a part of your must have camping gear. All it takes is 3-5 seconds of drinking out of the straw to start the flow of water through the filter! Easy and convenient, what more could you ask for?
Features: Within the stainless steel case (much more durable than the previous plastic version), the Lifestraw packs a two-stage carbon filtration system that can eliminate 99.9999% of waterborne bacteria and 99.9% of parasites. It's able to filter down to 0.2 microns, surpassing the EPA standard for water filters. The straw is made of food-grade plastic that will eliminate not only pathogens, but also odors and unpleasant tastes from the water, and even organic chemicals and chlorine!
The carbon filtration systems are designed to be replaceable, using capsules that are inexpensive and easy to switch out after 1,000 liters.
Price: At $50, this is a bit pricier than the plastic Lifestraw, but a much better choice for hardcore campers. With no batteries, heat, or chemicals required, this is the cheapest way to always have filtered water wherever you go.
