A few years ago I went fishing with a friend. After a few hours my water bottle was empty. Yet, in a twist of irony 350 cubic feet of water passed by me every second. He smiled, pulled out his bottle and gave me a sip of his precious water. I noticed the bottle was full, and it also had something inside. “It’s a water filter. Never run out of water!”, he said. GENIUS!
For someone who spent so much time in the water, it baffled me that I hadn’t come to that solution sooner by myself. For years I’d either run out of water and tough it out for a bit ; or I’d simply drink water directly from the stream I was fishing. If I was fishing high elevation water I never thought twice before taking a sip from the stream. Not the smartest idea in the world, I know. I know it because after years of drinking from streams, yet never having any symptoms, I finally asked my doctor to get tested for Giardia. I told him I often drank directly from streams which could have giardia and never used hand sanitizers. He gave me a dirty look but prescribed the tests. Sure enough, I had giardia. Never a symptom, I was just a carrier.
To a minimalist who doesn’t like carrying a backpack, but who is usually out long enough to require more than a “mere” 8 cups of water, the small water filter was like discovering fire for the first time. Immediately after fishing I went and bought myself a water bottle with a nifty filter built in. More often than not I am also surrounded by water, so it isn’t a matter of supply. It is a matter of clean supply.
I wasn’t crazy about the bottle solution. It was bulky and difficult to carry. Luckily the filter didn’t last me very long, so I did some more research and came across the minimalist’s water filtration dream. Straw-type water filters that I could put in my pocket when not hiking far, or couple to a water bottle if I was going to be away from the water for any period of time. The straw filters allow me to drink directly from the stream whenever I needed, and are very compact.
So, in case you’re looking for a solution not to run out of water again, carry a small water filter with you.
My preferred filter at the moment is the Aquamira Frontier Pro. They run only about $20, are only as thick as the handle of your tenkara rod, but 7 inches long. If will be hiking for any period of time I couple it with a flat bladder. My preferred one at the moment is the Platypus Softbottle, 0.5L for most of the time, 1L for slightly longer hikes. Often I just leave the bladder folded in case I need it, but drink directly from the stream otherwise.
