So I've been leaving jugs of water out on the side to let the chlorine evapourate and shocked at the difference in flavour, I can't go back to plain tap.

So I've been looking at water filters to get, and torn between the Brita which is a tried and tested brand which has good reliability, or this ZeroWater thing which apparently produces silky smooth water, but at a cost of the filters being expensive.
So I was wondering if anyone know if it was worth it for the ZeroWater or is it justa gimmick.
