Pros and Cons of Using a UV Light Water Filter

Safe drinking water is very important, but most people also want their water to taste good. While municipal water is usually treated to within safe levels of chemical and bacterial content, it can be beneficial to filter your water before drinking it both to improve the taste and to minimize any contaminants. One potential way to do this is with a Uv Light Water Filter. These filters can be set up to filter the water for your whole home if located in the right place.

Potential Advantages

The main advantage of a Uv Light Water Filter is that it doesn’t leave any chemical residues or tastes and doesn’t create any potentially harmful by-products. This makes it one of the more environmentally-friendly options. It kills up to 99.99% of all disease-causing microbes, including viruses, parasites, fungi and bacteria. It just requires the homeowner to change the UV light bulb used by the system each year. This type of filtration system also uses very minimal amounts of energy, just around the same amount as a 60 watt light bulb would use.

Potential Disadvantages

This type of water filter probably shouldn’t be the only type of filtration you use. It’s meant to be used with another type of filter, as it doesn’t remove heavy metals, chlorine or volatile organic compounds from the water. It also only purifies the water for that moment and doesn’t deal with any new contaminants that should enter the water like chlorine can. Should the water not be clear, the color in the water or the sediment in the water could absorb some of the ultraviolet light and make it less effective in filtering the water. Thus the water needs to be filtered before UV filtration to get rid of sediment, and then potentially filtered again after UV filtration to get rid of any remaining contaminants. Many people combine UV filtration with reverse osmosis systems or activated carbon filters to provide a complete household water filtration system and get the safest possible drinking water. Another alternative is to add some type of chlorine compound to the water after UV filtration, although this takes away some of the advantages of using UV filtration.
