Actually, I always take a diercon personal water filter, it claims it could filter out 99.9999% bacteria, and water tested good and great! Durable and portable!
When you go hiking or backpacking, will you take a water filter? If you do, what kind of filter you will take? Otherwise, when you choose a filter,what kind of filters you will interested in? Good looking or the functions?
When I come out, I usually take a diercon water filter product to filter out bacteria or others, and with a stove which boil out filtering water. it is safer and more convenient to take the bottle water.
