DIY water filter

thingiverse

Basic DIY bio-filter. This filter is composed by gravel, sand and activated charcoal. The filter is made in layers from bottom to top of charcoal, sand, gravel. I used some piece of cloth in the bottom and the top to contain the filter parts. Can be used in piped water, to remove some unpleasant flavors. I used 100% infill PLA. check our video - https://youtu.be/zljE3ZOYv8s Warning: You shouldn't use this filter in contaminated water. You can filter it, but should always boil it before drink.
