Micro Squeeze 濾水器

Took this on a three-day trip and it screwed straight onto my smartwater bottle without leaking a drop. Filling from a silty creek, it still flowed fast enough that I wasn't standing there pumping for ten minutes. Weighs basically nothing in my pack, which is exactly why it's staying in my kit.

Squeezing this thing by hand beats pumping any day, and it threaded right onto my bottle without leaking. Flow stayed steady even after filtering a few liters of silty creek water. Packed it for a weekend loop and it barely took up any room.

Took this on a three-day trip and the flow rate is genuinely impressive for something that fits in my palm. Setup took me under a minute, and I never once worried about the water I was drinking.
