What is Ultraviolet Radiation?

Ultraviolet Radiation is electromagnetic radiation with a wavelength shorter than visible light but longer than X-rays, in the range of 10 nm to 400 nm, and energies from 3eV to 124 eV.

Sunlight is a typical example of ultraviolet radiation.

UV Radiation divides into three bands: erythemal, UVB, and UVC.

The erythemal band is from 400 nm to 320 nm, the UVB band is from 320 nm to 280 nm, and UVC is from 280 nm to 100 nm.

How Do Ultraviolet Water Purification Systems Kill Bacteria And Viruses?

The UV disinfection systems use ultraviolet light bulbs to irradiate and kill bacteria, viruses, protozoan cysts, and other organisms.

Although the processes are different, ultraviolet systems all work on the same concept.

First, water is passed through a chamber where it comes into contact with an ultraviolet light bulb (which emits UV rays).

The UV purification system will next use pumps to force the water at high pressure through small openings in the front of this chamber.

As their nickname implies, these small openings are called “ultraviolet lamps,” and it is through them that the water passes.

Ultraviolet water purification systems work on the principle that ultraviolet light is harmful to microorganisms, including bacteria and viruses.

When a pathogen comes into contact with ultraviolet light, it absorbs that energy. It is then either killed outright or damaged enough to be rendered harmless.

Things to Consider When Purchasing the Best UV Water Purifier System

Water Quality

Water quality is just as important as the quality of any water filtration system.

If you buy a home UV water purifier, water quality is essential.

However, suppose you buy a portable UV purifier for your workplace or business. In that case, the water quality of the place may be as important.

Your water quality directly affects the quality of your water filtration system.

Along with the UV lamp wavelength, the house water filter needs to match the contaminants and impurities in your water.

Suppose you have very high levels of impurities or chemicals. In that case, you will need a more complex UV water filter system.


The warranty on each ultraviolet water purifier varies depending on the brand, so it is essential to know how long you will be covered.

UV light bulbs are the most common part to break, so it is essential to know your UV purifier comes with a warranty for the bulb’s life or not.

With most UV filtration, the warranty will cover the water tank and any other parts that are not replaceable.

If you can’t afford to purchase a new ultraviolet water filtration system right away but can afford to buy a new bulb, it might be worth finding out if the company offers a separate warranty for the bulb.

Flow Rate

The flow rate of your water filtration system is the amount of water that passes through in one minute.

If you have a high flow rate, you will need to replace the ultraviolet light bulb more often.

The ideal flow rate for a home ultraviolet water purifier is between 2 and 3 gallons.


With the wattage on the ultraviolet water filtration system varying from 5 watts to over 200 watts, you need to know how much electricity your best UV water purifier consumes.

Since Reverse Osmosis purifiers work best by exposing water to ultraviolet light for a specific time, wattage is essential.

If you have a high flow rate, your ultraviolet light bulb will need to be more powerful.

Your ultraviolet light bulb can be less potent if you have a low flow rate.

Your water purifying needs

Ultraviolet light is most effective when very high amounts of contaminants are in the water.

If you have low impurities in your water, you do not need complex water treatment.

Suppose you have issues with your home’s plumbing and have chemical contamination through your water. In that case, you will need a more complex filtration system.

If you do not have issues with your water, then a simple home UV purifier system will work just fine.

Advantages of UV Water Purification system

There are many advantages of a UV disinfection system. Some of them are listed below:

  • You don’t need chemicals in the process; you only need UV radiation.
  • The method uses less energy.
  • UV radiation does not react with the water molecules or other contaminants, so there is no secondary pollution.
  • The water purification plant is compact and occupies less space.
  • It is an effective process for water treatment of secondary wastewater from industries, tanneries, etc…
  • The end product, i.e., purified water, is free from microorganisms and odorless.
  • UV radiation does not affect water quality and does not produce any harmful by-products.
  • The operation and maintenance cost is significantly less than other UV purification processes, i.e., filtration, distillation, and ozonation.

Limitations or UV Water Purification Disadvantages

  • NEED FOR ELECTRICITY TO WORK: UV water purification systems need electricity to work.
  • WATER DEPOSITS ON THE LENS: Cleaning deposits on the UV lens requires the use of a dirty cloth.
  • DO NOT REMOVE ALL IMPURITIES: It can remove bacteria and viruses, but they do not remove all impurities found in water.
  • WATER TEMPERATURE: If the water is too cold or too hot, then the efficiency of the UV system decreases.
  • NO STORAGE TANK OPTION: One main disadvantage of UV water purifier systems is that they do not have a storage tank for treated water.
  • NO UV LIGHT SHUT-OFF: Another negative aspect of a UV water system is that there will be no light to generate the UV rays if the power goes out.
  • WATER NEEDS TO BE PRE-FILTERED: Pre-water filtration is necessary for the UV purifier system.

Maintenance Tips for Home UV Water Purification Systems

While every UV water system will come with manufacturer recommendations included in the literature and guides for operation and maintenance; you could follow Reverse Osmosis instructions to get excellent performance:

  • Clean the lamp every six months (or as advised by your manufacturer).
  • Use a UV light bulb replacement when you notice flickering or dimming the light.
  • Clean any pre-filters after turning brown (usually after about 1 month).
  • If you have hard water, you may need to replace the resin every six months.
  • Clean the post UV filter after turning black (usually around 1 year).
  • If your water is very soft, you may need to replace the resin every year.
  • Check your flow sensors regularly by running plain water through the cleaner. If you notice the flow meter bearing an incorrect reading, contact us immediately to make an appointment for service.
  • Make sure your UV air cleaner is vented to the outside of your house. Check with your manufacturer’s literature or contact the manufacturer if you’re unsure.


Quite a few water filters buzz in the market; it’s advised to choose one with many benefits and that is easy to use.
