Tourist filters

Tourist

— filters designed for use "far from civilization", primarily in tourist trips. They can have different designs: some models are a container with a filter element, others use a lid for filtration, others can be supplemented with a built-in pump for taking water from natural reservoirs, etc. In everyday life, such models are of little use due to low productivity, but in nature they will be indispensable — their dimensions and weight are small, and the possibilities are usually quite enough for several tourists.
