iSpring US31
The iSpring US31 is the simplest drinking filtration system in this guide. As a result of not using a tank, and being quite basic, this system relies entirely on water coming out of the tap and, as that water comes out, filters the chemicals, metals, and dissolved solids within the water. This makes it easy to produce clean drinking water, as well as mineral water.
