This process includes a pre-filter, a high-performance reverse osmosis membrane, a post-filter, and a carbon block filter. The pre-filter removes larger particles and sediment, while the reverse osmosis membrane filters out a wide range of contaminants, including dissolved solids, heavy metals, and microscopic impurities.
