Selecting the correct technology depends on the source water contaminants. For heavy metals and high TDS (Total Dissolved Solids), a Reverse Osmosis (RO) system is the gold standard. If the goal is to remove chlorine, odors, and organic chemicals while retaining minerals, Activated Carbon filters are ideal. For bacterial and viral protection, ensure the system includes an Ultrafiltration (UF) membrane or UV Sterilization stage. Always request a water analysis report from the target market to match the filter specifications to local needs.
