LifeStraw, a Time Magazine Invention of the Year Winner, removes a minimum of 99.9999% of waterborne bacteria. In areas plagued with dirty and unsafe drinking water, it filters up to 1,000 liters per apparatus into potable refreshment without the use of chemicals, batteries, or even moving parts. The LifeStraw also weighs only 2 ounces, making it easy to tote along on camping, hunting, or other trips off the beaten path, as well as simple to tuck away in homes or car glove compartments for emergency situations, or raging parties and bro nights that devolve into games of I Dare You to Drink That.
The LifeStraw features a high flow rate (though it takes about 3 to 5 seconds for the first drops of water to travel through the filtration system), and is able to reduce water turbidity (cloudiness) and toxicity by staving off particles of approximately 0.2 microns, and slashing a minimum of 99.9%+ of protozoan parasites. However, it cannot filter chemicals, salt, viruses, heavy metals, or ugly tastes. So sorry, citizens of Florida. You're stuck with your thick, pus-infused tap water. LifeStraws have a shelf life of 5 years.
