There are a few types of filters you can get for backpacking and camping.
TYPES HERE---- GRAVITY STRAW PUMP PILLS WHAT?
I had a couple friends who used THIS MSR NALGENE. When we would camp we would fill the bucket LINK TO MYBUCKET. Bring the water to camp and each person would pump their own water to drink and eat with. It was a pain in the butt. That lead me to lean towards trying out a gravity fed filter.
I am not affiliated with LifeStraw. Purchsed this for my own biological needs.
