How a UV Llight Water Purifier Works

UV water filters are relatively new to the water filtration industry. They work under a simple premise: certain wave lengths of UV light have been approved by the US Environmental Protection Agency (EPA) for use in the sterilization of water. UV light has been shown to kill harmful pathogens and bacterium without the need for chemicals like chlorine. These filters rely upon a sanitized stainless steel chamber, where the water is housed and purified using UV light. It can be aptly compared to using boiling methods or distilling methods to purify water.

With UV light, the energy required to purify the water is far less than traditional boiling or distilling methods require, making it a far more cost effective and environmentally friendly solution for homeowners. UV treatment of water has been studied extensively and is accepted as a form of water purification that effectively kills any microorganisms, viruses or bacterium and pathogens found in standard tap water, according to the U.S. Food & Drug Administration (FDA).

It is important to note that a UV filter is not a water softer, a hard water filter or a sediment filter. It is ideal for homes and businesses that have unsafe water, where a chlorinator (a filter that slowly introduces chlorine to kill pathogens) would have to otherwise be used. In most cases, a UV filter can be used instead. It is advised that this filter be used in tandem with another filter that removes any minerals like calcium and manganese or iron for the best overall results.
