When you find yourself dealing with water contamination, the first thing that you should think of is finding a high-quality professional water filter. Luckily, there are many available you can choose from on the market.

Manufacturer companies produce many types of affordable, yet high-performance water purification systems, so you won’t have trouble finding the right one for your specific problem. 

All you need to do is make a quick research and understand the advantages and disadvantages of each water filtration system. 

In this article, we are going to discuss a popular water treatment choice: the UV water filtration. 

What are UV Water Filters?

UV water filters are known as one of the most powerful, yet affordable water treatment systems. These water treatment systems are mainly used to remove  biological contaminants from drinking water in residential homes. 

UV filters are  highly reliable purification systems and nothing shows this better than the numbers based on reports and user feedback. They are able to destroy up to 99.99% of such waterborne contaminants and microorganisms as bacteria, viruses, mold, pathogens, giardia and cryptosporidium. 

Some resistant viruses such as hepatitis can survive in water and it can be transmitted. However, even if it is especially hard to destroy, UV filters have no trouble destroying them and removing them from your water. 

And the great news is that UV filters are capable of removing other inorganic contaminants too. 

How UV Water Filters Work?

To fully understand how UV water filters work, first let’s talk a bit about UV light itself. The ultraviolet (UV) light is a mix of different light sources, including sunlight. It is invisible and at a certain intensity the power of UV light is capable of killing the DNA in microorganisms.

The efficiency of water filter systems that use UV light is based on this powerful quality. 

The base of ultraviolet water treatment systems is a UV light source with an output of around 254 nanometers. 

With the help of UV light, these filter systems can eliminate such contaminants and viruses that are extremely hard or even impossible to remove by other filtration systems. 

Now that we understand the UV light, let’s see the method water filters using ultraviolet light rely on. 

The UV light source is mounted in front of the chamber, also called the flow chamber. This is where the unfiltered water passes.. As the water flows through the chamber, it is exposed to the UV light and the exposure removes all viruses, bacteria, pathogens, microorganisms and a broad range of other harmful contaminants as well. 

The exposure has such a powerful impact on the contaminants existing in water, that the radiation can kill such water-borne diseases as Gastroenteritis, Typhoid, Cholera, Hepatitis and flu. UV water filter systems are 99.99% effective, whether you filter water coming from your private well or from your municipal water supply.

The Advantages and Disadvantages of UV Water Filters

Similarly to other water filtration systems, in the case of UV filters it is good to understand the advantages and disadvantages as well. Thanks to the advanced design and powerful filtering method UV filters are based on, there are a significantly larger number of benefits than disadvantages.

See this short list below wrapping up the main features (whether good or bad) you should take into consideration before purchasing a professional ultraviolet water filter system:


  1. As you have already seen, UV filters are highly efficient water treatment systems. They are able to remove 99.999% of microorganisms and other contaminants. 
  2. They are easy-to-install, so you can skip paying expensive fees to a plumber. You can rely on the manual provided by the manufacturer company.
  3. UV water filters are easy to maintain as well. The most you will do is changing the light bulb once a year or occasionally changing the filter if that is the case.
  4. Affordability is a great feature water filter buyers prioritize. Looking at the price range, you easily find a high quality UV filter at a low price. 
  5. Considering the energy these UV filters use, they save energy as well. Basically, they use the same amount of energy as a regular  60-watt light bulb.
  6. Uv filters are one of the most reliable water filtration systems in terms of working capability. They work non-stop, so you will have immediate access to freshly filtered water any time of the day.
  7. They don’t use any chemicals to remove contaminants from water, so they are safe for children and the environment as well. 
  8. Thanks to the fast flow filtering method, you won’t need to install a holding tank to hold your water. 
  9. In case you worry that installing an UV water filter will lead to an increase of water consumption, forget about it! UV filters filter every single drop, so you won’t waste any water during the filtering process.


  1. One of the most important disadvantages of UV water filters is that you cannot use them without electricity. 
  2. Ultraviolet filters fight microorganisms efficiently, but unfortunately they can’t deal with other contaminants such as heavy metals or chlorine.
  3. The floating particles in water may block the UV light. This means that in order to make sure your water is ready to be purified, pre-filtration is recommended.
