Water filters operate using various mechanisms to remove contaminants. Activated carbon filters, for example, use a process called adsorption to trap pollutants. Reverse osmosis systems utilize a semi-permeable membrane to separate impurities. Other technologies include ion exchange, which replaces harmful ions with harmless ones, and ultraviolet (UV) purification, which inactivates microorganisms. Understanding these mechanisms helps in selecting the appropriate filter for specific contaminants.
