Thanks. Using a Katadyn myself; it has an adjustable float and that thread attachment is a lifesaver.

Unless you really care about saving 1 oz of weight get the regular sized mini. Better flow rate and lasts longer when you really need it. I’ve switched back to the full-size for backpacking because the trade offs for the mini aren’t worth it.

Assuming you have access to transparent PET bottles and sunlight water filtration is basically solved.
