Design for the Poor
The Portable Filter is aimed at helping poor people in underdeveloped countries. These people usually have difficulties in access to clean drinking water, which always lead to diseases and sometimes even endanger their lives. This portable design is compact and easy to carry, which gives users the convenience of purifying water for drinking anywhere whenever they feel the need. The stroke between stretching and shrinking a pipe can generate pressure and push water through the filter to make it clean.
