The MINCH Household Water Filter is a gravity-fed system designed to provide safe drinking water in households and communities. It utilizes a combination of sand and diatomaceous earth as its filtration media. Contaminated water is poured into the top of the filter and gravity pulls it through the layers of sand and diatomaceous earth. These materials act as a physical barrier, trapping bacteria, protozoa, and other particulate matter. The filtered water then collects in a clean container below. This simple yet effective technology aims to improve access to safe drinking water.
