A water purifier is an essential device designed to enhance the quality of drinking water by eliminating harmful contaminants and impurities. Utilizing advanced purification technologies, such as filtration, reverse osmosis (RO), ultraviolet (UV) treatment, and activated carbon absorption, these systems ensure safe and clean water for households and businesses alike. The filtration process captures sediments, dust, and larger particles, while RO effectively removes dissolved salts, heavy metals, and microorganisms by pushing water through a semi-permeable membrane. UV treatment disinfects water using ultraviolet light, rendering bacteria and viruses inactive without chemicals, ensuring a pure drinking experience. Additionally, activated carbon effectively absorbs chlorine, unpleasant tastes, and odors, enhancing the overall flavor of the water.
