Modern water purifiers make water safe for drinking. You may ask how. Water purifiers make use of a purification technology that does all the work. UV (ultraviolet) purification is a leading water purification technology, and most modern water purifiers use it.
The best home water purifiers use UV purification to provide pure, safe drinking water. This article discusses some of the essential things to know about UV water purification.

What Is The Working Mechanism of The UV Water Purification?

UV water purification systems use ultraviolet rays to purify water by killing microorganisms present in the water. The UV rays kill water-borne organisms by disrupting their DNA, preventing their reproduction. Fortunately, UV rays do not cause any chemical change in water. Therefore, water purified through UV rays retains their original taste and they are free from harmful microorganisms.
Low-pressure mercury vapor lamps produce ultraviolet radiation at a specified level. Therefore, modern water purifiers use them. Also, with the unique installation of mercury vapor lamps, they do not contact the water.

What Are the Benefits of UV Water Purification?

Choosing a UV water purifier has many benefits, including;
A significant advantage of using a UV water purifier is instant water purification. Once you switch on the UV purifier's electric supply, it purifies water immediately.
A UV water purifier does not need chemicals in its purification process. Therefore, it doesn't adulterate the color, odor, and taste of water.
Using a UV water purifier is cost-effective. The system uses a mercury vapor lamp which has similar power consumption and price to a standard light bulb
UV water purifiers use ultraviolet rays to kill disease-causing germs and bacteria, including Cryptosporidium, Giardia, and E. Coli, present in water

How To Maintain UV Water Purifiers

Although UV water purifiers are durable, it depends on how you maintain them regularly. Below are a few maintenance tips helpful in improving the function of your UV water purifier
Over time, the internal parts of a UV water purifier get dirty because of minerals and tiny debris accumulation and build-up. The dirt builds up in the glass housing of the mercury vapor lamp, interfering with the UV rays' penetration and affecting the purifier's function. It is best to clean the internal parts of your UV purifiers every one or two months, depending on your home's quality of water supply.
Because UV lamps tend to solarize, over time, their intensity decreases. Frequently turning on and off the UV lamp of a water purifier increases the rate of solarization. Therefore, it is best to employ the services of a professional in checking your water purifier's UV lamp annually. If the UV lamp has started to solarize, then it is due for replacement.


Although several water purification processes exist, UV purification is a leading method that does not alter your drinking water's taste, color, or odor. The UV purifier purifies water instantly without the use of chemicals. Furthermore, it is a cost-effective method. Proper maintenance of your UV water purifier improves its durability.
