What is a UV water filter?

0

Anyone that is concerned about possibly having microorganisms in their drinking water may want to install a UV water filter (a.k.a. UV water purification system).  This filter works by enclosing a UV lamp in a clear sleeve that is made of either quartz or heavy glass.  As the water passes by the lamp it is exposed to UV rays that destroy harmful microbes (i.e. viruses, hepatitis, the enteric virus, the virus that causes Legionnaire’s disease).

There are several different advantages to using a UV water filter, including:

  • There are no chemicals in the water so the taste, color and pH will not be altered and thus there won’t be any cancer-causing bi-products such as those that are present in chlorine.
  • This water won’t damage your plumbing or septic tank systems.
  • It is easy and inexpensive to install and maintain a UV water filter.
  • This is one of the most effectives ways in which to kill microbes in your water.
  • It takes very little energy to run a UV water filter.  In fact, it only takes the equivalent of the electricity that a 60-watt light bulb uses in order to run the UV water filter.

Of course, there are also some disadvantages, including:

  • You need to have electricity in order to run the UV lamp.
  • Whenever the water passes by the UV lamp it must be clear of sediment or a filter will form, preventing the UV rays from killing the microbes.  So, if the water is too dirty, it must be pre-filtered.

It is easy to maintain a UV water filter.  You simply need to replace the UV bulb every year and clean the clear sleeve that surrounds this bulb a couple of times each year.

Those who are concerned with microorganisms in their drinking water may be interested in installing an ultraviolet (UV) water purification system, also called a UV water filter. The UV water filter works by enclosing a UV lamp in a clear sleeve, typically made of quartz or heavy glass. The water passes by the lamp and is exposed to the UV rays. The UV rays work to destroy microbes that are harmful if consumed by humans, thereby purifying the water. There are several advantages to using a UV water filter over other water purification systems. First, chemicals are not introduced in the water. Consequently, the taste, color, and pH of the water remain unaltered and there are no cancer-causing bi-products, as there is with chlorine. Second, water that has been treated with UV rays will never damage plumbing or septic tank systems. Third, installation and maintenance is both simple and inexpensive. Fourth, it is one of the most effective ways to kill disease-causing microbes, such as viruse
