Aging infrastructure coupled with an increase in population and water contamination issues require innovative water treatment solutions that don’t compromise the safety of your water and ensure highly potable water in the comfort of your home.

Ultraviolet water filters are one such water treatment solution that’s safe, both for consumers and the environment, and can be used with ease by consumers at home. These water treatment units are easy to operate, have low running costs, and they’re suitable for at-home water filtration and commercial use as well.

But how do UV water sanitisers work? And are UV system a worthwhile investment? This article will focus on topics that concern the efficiency, usability, and the advantages and disadvantages of UV water sanitising systems.

What are UV Filters?

UV water filters are one of the most efficient and cost-effective water purification systems. These water treatment systems are mainly used to purify residential drinking water from biological contaminants. They are able to destroy up to 99.99% of waterborne contaminants and microorganisms like bacteria, viruses, mold, pathogens, giardia and cryptosporidium.

For example, hepatitis A is widely known as a highly resistant virus that is hard to destroy, but UV filters can easily remove it from water. However, this isn’t the complete list of what you can achieve with an UV system. By using a complex UV water filter you can also remove inorganic contaminants.

How UV Filters Work?

UV light consists of different light sources, including the sun. Ultraviolet light is invisible and it can reach an intensity as high as to damage the DNA of microorganisms. Thanks to its efficiency, it can eliminate viruses that are hard or impossible to remove by way of other water purification systems.

At the base of  any ultraviolet water treatment system, there is an UV light source with an output of around 254 nanometres. This light source is responsible for eradicating bacteria, thanks to the wavelength at which it operates.

But how do ultraviolet light water filter systems work? This type of purification system consists of the UV light source, which is mounted in front of the UV chamber. This flow chamber is where the water passes and it is exposed to the UV light as it flows through the chamber. The exposure removes all bacteria, viruses, pathogens, microorganisms, etc.

With an effectiveness of 99.99%, UV rays eradicate water-borne diseases such as Gastroenteritis, Typhoid, Cholera, Hepatitis and the Flu. Whether you own a private well, or you receive your drinking water from a municipal water supply, ultraviolet water filters can be used to eliminate disease-causing contaminants and to make sure your drinking water is pure and safe to consume.

The Advantages and disadvantages of UV Filters

As we have previously mentioned, UV filters are innovative, highly efficient water purification systems that are easy-to-use in order to eliminate dangerous contaminants from your residential drinking water. Let’s take a look at the advantages and disadvantages of these ultraviolet water filters:

The advantages of UV water purifiers

  • Cost-effective: There is a wide range of ultraviolet water filters on the market available at a reasonable cost. A home UV water system can range from £99 to £299+, while commercial ones are much more expensive with some units costing over £1900. On average, a home UV filter purification system uses the same amount of energy as a 60-watt light bulb.
  • Highly efficient: Efficiency is highly guaranteed with these systems. To be precise, UV filters are capable to remove 99.99% of microorganisms from your drinking water. By using this type of water purification system, you can make sure that the water you drink day by day is safe to drink, and it keeps you and your family healthy.
  • Chemical Free: Ultraviolet filters don’t use any chemicals. This filter system consists only of a light source and a chamber, where water passes through. As water flows through the chamber, it’s exposed to UV light, creating the exposure needed to destroys the harmful bacteria.
  • Easy-to-Install: You don’t need to call a plumber and pay expensive bills to get your water filter installed. UV filters are easy-to-install by using the simple instructions provided by the manufacturer company.
  • Easy to maintain: Following installation, maintenance isn’t a worry. UV filters need annual maintenance which is simple and easy-to-do, you will have to change the bulb once a year. Occasionally, the replacement of the quartz sleeve that protects the lamp could be required too.
  • Fast flow: You don’t need to install a holding tank for the water you want to purify. The water passes through the chamber fast enough to maintain a good water flow.
  • Safe for children: UV water filters are 100% chemical free, so you won’t have to worry about the risk of unwanted chemicals being added to your water during filtration. During installation and maintenance you won’t need to handle any chemicals either.
  • Safe for the environment: No by-products emitted, UV water purification system are a great choice if you pay attention to using environmentally-friendly products.
  • Saves energy: UV filters are famous for their low energy use during the purification process. As we have mentioned before, these filters use the same energy as a light bulb.
  • Clean: Purifying and clearing your water is solved, but how about the cleaning of your water filter system? Good news, in case of UV water filters you won’t have to deal with dirty filters or filter media, ever!
  • Non-stop working capability: Ultraviolet filters work 24/7/365. The non-stop working capability ensures that you will never lack pure drinking water again.
  • Internationally approved: Approved and recognized as a water treatment solution worldwide, UV filters are a reliable choice in water purification. UV filters are one of the 4 disinfection methods approved by FDA on the market.
  • No waste: UV filters don’t waste any water during the purifying process. Every single drop will be purified, so you don’t have to worry about the increase of your water consumption or bills.

The Disadvantages of UV Filters

  • Limited to microorganism: Unfortunately, UV light filters are only efficient against microorganisms. They cannot remove other harmful contaminants such as chlorine, heavy metals or fluoride. It is highly advised to get your water tested before purchasing any water purification system, so you can make the right decision regarding the type of water filter you need.
  • Pre-filtration is required: UV water filter system work properly only if the water that’s being purified is clear of sediments. What does this mean? If your water is cloudy and you can see sediments or dirt floating around in it, you should pre-filter it before using an UV filter. If the little floating particles block the UV light, the purifying process won’t be successful.

  • Electricity needed: In order to use your UV water purifier, you will need access to electricity. This means that you won’t be able to use your filter off-grid or in cases of emergency unless you can produce electricity.

Are UV Filters Worth It?

Being approved by many international health organizations is a definite guarantee that UV water purifiers are worth it. These unit are a simple and easy way to purify your drinking water that has potability issues because of microbiological contamination. Be advised that pre-filtration or post-filtration is required, but even so, UV filters are a cost-effective, highly efficient and reliable choice to treat your water.
