Filtering water is a multi-step process that ensures contaminants, particles, and harmful substances are removed to produce clean, safe water. A typical water filtration machine is composed of several essential parts that work together to achieve this. The inlet valve controls the flow of raw water into the system, while the pre-filters (such as sediment and carbon filters) trap dirt, rust, chlorine, and odors. The high-pressure pump pushes water through the membrane unit, often using reverse osmosis (RO), which eliminates dissolved salts, heavy metals, and microorganisms. The UV chamber or ozone unit may then be used to kill any remaining bacteria and viruses. Finally, a post-carbon filter polishes the taste and quality of the water before it reaches the storage tank and the outlet faucet for use. Together, these components ensure water is purified efficiently and consistently for consumption.
