CSI Water Nitro water filter system

Many New Hampshire and Maine water wells produce drinking water that contains iron and manganese which can stain clothes and give water poor taste and appearance and sulfur which produces a rotten egg odor.  These water wells may also be plagued by low pH commonly known as acidity.  Acidity can destroy plumbing and fixtures by reacting with and slowly eroding the metal within.
