Municipal water is cleaned and filtered to a level compliant with the NZ drinking water standards. However, contamination can still occur. Certain contaminants are not considered to be a human health issues so are not removed at all; other contaminants may enter our water supply via cracks and breaks in the water delivery infrastructure. For this reason, many home owners have invested in a water filtration system as a final barrier for their home. Also, whilst chlorine is a good disinfectant in town water, it can also make water smell and taste bad and can contribute to eye and skin irritations. Adding a whole-house solution or a single point-of-use filter to improve the quality of your drinking water is good sense for your own health, your family and visitors.
