Hard water dries out skin and makes hair brittle. It causes soap scum in tubs and showers and spots on faucets and fixtures. It also causes scaling in appliances, which results in less efficiency and costly repairs.
The taste and smell of chlorine are unappealing and can also dry out your skin and hair. While municipalities use chlorine to disinfect the water supply, it should be filtered out before you use it to eliminate these effects.
