A 5-stage UV+UF water purifier typically uses a combination of filtration technologies to ensure clean and safe drinking water. Here’s a description of each stage:
1)Pre-Filter (Sediment Filter)
•Purpose: Removes large particles such as sand, dirt, and rust.
•Description: This stage usually employs a sediment filter with a micron rating to trap and eliminate these contaminants, protecting the downstream filters and extending their lifespan.
2)Activated Carbon Filter
•Purpose: Removes chlorine, volatile organic compounds (VOCs), and other chemicals that affect water taste and odor.
•Description: The activated carbon filter absorbs and reduces impurities and organic substances, improving the overall taste and smell of the water.
3)Carbon Block Filter
•Purpose: Further removes smaller contaminants and organic impurities.
Description: This filter stage provides additional carbon filtration to catch any remaining chlorine, VOCs, and other microscopic impurities, enhancing water quality and safety.
4)Ultra-Filtration (UF)
•Purpose: Eliminates bacteria, viruses, and cysts while retaining essential minerals.
•Description: The UF membrane has fine pores that allow water and beneficial minerals to pass through but block microorganisms and larger pathogens, ensuring microbiologically safe drinking water.
5)Ultraviolet (UV) Sterilizer
•Purpose: Kills any remaining bacteria, viruses, and other pathogens.
•Description: In this stage, water passes through a UV chamber where it is exposed to ultraviolet light. This light effectively inactivates microorganisms by disrupting their DNA, ensuring that the water is free from harmful pathogens.
