Filter-cap / bottle cap filter

Filter-cap
Filter-cap

When going hiking , we usually take a bottle of water with us. But it’s easy to be drunken out. Then we need to look for a water intake or buy another one , which

is often a difficult task in the field.
Filter-cap is a bottle cap which can filter water from streams or lakes. There are some small holes on the surface and several filtrating layers inside which can

filter out microbes and harmful materials, and store the pure water in the bottle. So whenever we need drinking water, we only need a small Filter-cap.
