Has anyone heard of a filterless system. Apprently, its a new technology. It can be installed on the incoming water pipe/loo externally and is just an electrical gadget. It does purify but only uses electric energy to remove impurities. They say this is good as it does not remove minerals from the water and is also economical as it does not waste any water.
I heard it can be bought for approx. $300. Anyone heard of it? Any details?
