Under-Sink Filter Made Portable
The first Pure Paani hand-powered water filter connects a standard under sink, filter bowl and cartridge to a hand pump. Water is pulled in through a flexible tube, drawn through 10″ filter cartridge and outlet though a rigid, downward pipe.
This filter bowl/cartridge system is commonly found in under-sink systems that have access to piped water.
When the filter cartridge is due for replacement, the microentrepreneur can easily unscrew the transparent filter bowl, insert a new piece, and close the system again.
