Life Straws

 Life Straws 
life straws are usually used in different country's where theres not much clean water for them to drink like a muddy stream. They are also used for campers and trampers.
The Life straw is a hollow-membrane filter built into a straw. You place straw into the water, and drink. Sucking the water up through the straw forces it through the filter, which removes 99.9999% of bacteria, and 99.9% of protozoa, down to 0.2 microns, with a filter that lasts for 1000 litres.
How long do they last?
the life straw can filter up to 1,000 litres (264 gallons). If you used it every day for the amount you need per day than the life straw would last about one year if you used it just for camping tramping and outdoor activities then it will last longer.
Life Straws save lives.
