The filter effectively purifies water in three advanced technical stages, giving you clear, pure water free from unpleasant odors and tastes. Working Principle: Stage 1 (Sediment Filter): Removes all suspended impurities, rust, and dirt from the water, even microscopic particles. Stage 2 (Carbon Filter): Absorbs chlorine, dissolved impurities, toxins, heavy metals, and other substances that are difficult to see with the naked eye. Stage 3 (Sediment Filter): The filter operates with 1-micron pores to ensure removal of rust, fine impurities, and suspended dust particles remaining after the previous filtration stages.
