>>2158646i use activated aquarium charcoal. its cheap as fuck (dont get jewed by the 25g refill packs of the filters mafia)
this works great if the water is not clear of solids or is in particular swampy. Sponge filter on intake. coal filter it once the pill did its work.
I do add isotonic tabs sometimes if I feel like drinking something with taste.
>>2158647yeah i have 2x 1L bottles that i use to process the water. Then I refill my water bladder with them. I use a bottle adaptor and inline coal filter i squeeze it through.
Drink from bladder. Refill with clean water from bottles. Once the first bottle is empty, I refill it from a water source and start the timer.
