RO (Reverse Osmosis) uses a semi-permeable membrane to remove dissolved salts, heavy metals, and microscopic impurities — ideal for hard water with high TDS levels above 300 ppm. UV (Ultraviolet) purification kills bacteria, viruses, and pathogens using UV light but does not remove dissolved solids, making it suitable for soft water with low TDS. UF (Ultrafiltration) uses a hollow fiber membrane to block bacteria and suspended particles while retaining essential minerals, working without electricity and best for water with low TDS and no hardness.

Sediment and carbon pre-filters should be replaced every 6 to 8 months depending on your water quality and daily usage. The RO membrane typically lasts 18 to 24 months before its rejection rate begins to decline. Post-carbon taste enhancer filters need replacement every 12 months to maintain fresh-tasting water. We send timely service reminders to every customer and offer annual maintenance contracts that include all scheduled filter changes.

Annual Maintenance Contract (AMC) charges typically range from ₹1,800 to ₹3,500 per year depending on the model and number of filter stages. Our standard AMC covers two scheduled preventive maintenance visits, all filter replacements as per schedule, unlimited breakdown service calls, and free labour for repairs. Premium AMC plans also include RO membrane replacement and priority same-day service for an additional fee.

All our residential water purifiers come with a standard 1-year comprehensive warranty covering manufacturing defects, electrical components, and membrane performance. Extended warranty options are available for 2 or 3 additional years at a nominal cost during purchase. Warranty claims are processed within 48 hours, and we replace any defective parts at no charge during the warranty period.

Alkaline RO systems add a mineral cartridge after the RO membrane that raises the water's pH to a slightly alkaline level, typically between 7.5 and 8.5. This process reintroduces essential minerals like calcium, magnesium, and potassium that are stripped during reverse osmosis. While standard RO water is perfectly safe, alkaline RO offers potential health benefits including better hydration and acid-neutralizing properties that many health-conscious families prefer.

Yes, under-sink RO systems are designed to fit neatly inside standard kitchen cabinets measuring at least 45cm wide and 50cm high. Our installation team assesses your cabinet space, plumbing access, and electrical outlet proximity before recommending the right model. The installation is completed within 60 to 90 minutes with minimal drilling, and we provide a dedicated designer faucet that mounts on your sink or countertop.

Traditional RO systems produce approximately 3 litres of reject water for every 1 litre of purified water, resulting in a 25% recovery rate. Our advanced residential RO systems feature high-efficiency membranes and booster pumps that achieve up to 50% recovery, meaning only 1 litre is wasted per litre purified. The reject water is perfectly suitable for mopping floors, watering plants, or washing utensils, and we can install a storage tank to collect it.

The Bureau of Indian Standards recommends TDS levels between 50 and 150 ppm for optimal drinking water taste and safety. RO systems typically reduce TDS by 90 to 95%, so water with an input TDS of 500 ppm will produce purified water around 50 ppm. If your source water TDS is below 150 ppm, a UV or UF system may be more appropriate as it preserves beneficial minerals while eliminating pathogens.

Hot and cold RO systems include a built-in heating and cooling module that consumes approximately 500 to 800 watts during active heating mode and 80 to 120 watts for cooling. On standby, the power draw drops to under 5 watts, keeping monthly electricity costs around ₹150 to ₹250 for an average family. Modern models feature energy-saving modes and rapid heating technology that brings water to 90°C in under 5 seconds, minimising power usage.

If your municipal water supply has TDS below 200 ppm and is consistently soft with no visible sediments, a UV purifier provides adequate protection against bacteria and viruses. For borewell water or areas with high bacterial contamination but low dissolved solids, UF is the better choice as it physically filters pathogens without needing electricity. Our free water testing service measures TDS, hardness, chlorine levels, and bacterial presence to give you a definitive recommendation.

Each service visit includes a thorough sanitisation of the storage tank and internal pipelines, inspection of all filters and the RO membrane, checking the TDS rejection rate, cleaning the pre-filter housing, and testing the auto-shutoff float valve. Our technician also calibrates the TDS controller, verifies the UV lamp intensity, and provides a digital water quality report showing before-and-after TDS readings. Any worn O-rings, tubing, or connectors are replaced at no extra labour cost.

Absolutely, we offer professional relocation and reinstallation services for all water purifier brands starting at ₹499. Our team safely unmounts the unit, drains all water to prevent spillage during transit, and reinstalls it at your new location with fresh wall plugs and plumbing connections. We also perform a full system check and water quality test after reinstallation to ensure everything functions perfectly in the new environment.
