Ultraviolet water purification is the most effective method for disinfecting bacteria from the water. Ultraviolet (UV) rays penetrate harmful pathogens in your home’s water and destroy illness-causing microorganisms by attacking their genetic core (DNA). This is extremely efficient in eliminating their ability to reproduce.
In a UV water filter system, UV ( Ultraviolet ) rays are used to kill the harmful bacteria from the water. Hence the water is completely disinfected from pathogens. UV water purifier is good for health because it kills all the harmful microbes present in the water without affecting the taste.
Spring water and purified water are popular and excellent choices. Spring water is naturally filtered underground. It’s collected from springs or boreholes.
The truth is YES, most water purification tablets expire. Water purification is commonly done using two chemical options; iodine or chlorine and all the options come with an expiry date. These chemicals neutralize viruses, bacteria, and other parasitic protozoans in water leaving them harmless and the water safe for human consumption.
