1. Begin by identifying your water type: hard water from bore wells and tankers requires RO, while soft water from rivers and municipal supply is best treated with UV.
Assess the impurities in your water: solid particles, dissolved inorganic compounds, organic compounds, decontaminants, and biological contaminants each require specific treatments.
Reverse Osmosis (RO) technology is ideal for high TDS levels (200-2000 ppm), removing calcium, magnesium, and dangerous chemicals like lead and mercury.
Ultraviolet (UV) technology kills bacteria and viruses in low TDS water but doesn’t remove dissolved impurities; it's best used with pre-filters or activated carbon filters.
Electro-Adsorption Technology (EAT) removes dirt, dust, ions, germs, and harmful chemicals through a five-step filtration process, suitable for various impurities.
Ultrafiltration (UF) technology is gravity-based, effective for cyst removal without electricity, ideal for low TDS water when combined with sediment and carbon filters.
Alkaline technology filters harmful acids from water, suitable for areas with sour or acidic tasting water and low TDS levels.
Determine the TDS level of your water to choose the right purifier type: below 300 ppm needs gravity-based, UV, UF, or EAT; above 300 ppm requires RO combinations.
Look for key features like storage tanks for purified water, TDS controllers to maintain mineral levels, and display indicators for status and maintenance alerts.
Consider additional filters: activated carbon for chlorine and organic impurities, membranes for biological contaminants, and sediment pre-filters to enhance purifier lifespan.
