Water quality across India has become a serious public health concern. From dissolved heavy metals in borewell groundwater to chlorine and harmful by-products in municipal supply lines — the threats to your family's daily health are very real. Whether you live in the heart of Delhi, a suburb of Bengaluru, or a growing town in Rajasthan, the need for proper, certified water treatment has never been more urgent. At Kita Systems, we have spent over 12 years developing water solutions genuinely engineered for Indian conditions — not imported designs that ignore local realities.
Why You Need the Best Domestic Water Purifier in India
India's water supply presents unique and varied challenges. In northern states like Delhi, Haryana, and Rajasthan, groundwater contains elevated levels of total dissolved solids (TDS), fluoride, and nitrates from agricultural runoff. In coastal cities, saltwater intrusion raises sodium content beyond safe limits. In urban areas, aging pipe infrastructure causes recontamination of treated municipal water before it reaches the household tap. No single approach works everywhere — which is exactly why selecting the right purification technology matters so much.
When evaluating options for the best domestic water purifier in India, the most important factor is matching the purification technology to your specific water source and TDS level. RO (Reverse Osmosis) systems are widely considered the most comprehensive solution for Indian households, particularly where TDS exceeds 200 ppm. A quality RO purifier passes water through a semi-permeable membrane with pores of just 0.0001 microns — effectively blocking dissolved salts, heavy metals like lead and arsenic, and biological contaminants including bacteria and viruses in one powerful stage.
Kita Systems RO purifiers go a meaningful step further by combining RO filtration with UV disinfection and a precision TDS controller that retains essential minerals like calcium and magnesium. This ensures the water reaching your family's glass is not only completely pure but also naturally balanced — healthy to drink every single day. Our systems are designed specifically for Indian household realities: voltage fluctuation protection, compact wall-mount or under-sink designs, and quick-change filter cartridges that make annual maintenance simple and affordable.
Key Factors When Choosing a Water Purifier
Before purchasing, test your water's TDS level using an affordable TDS meter — available online for under ₹300. If your reading is above 200 ppm, an RO purifier is strongly recommended. For water with TDS below 200 ppm (typically treated municipal water), a UV+UF purifier may be sufficient. Always verify BIS ISI marking, check for smart filter change indicators, and confirm the membrane quality. Cheap membranes degrade within months and allow contaminants to pass through. With Kita Systems, every component is sourced from certified suppliers and tested before assembly at our Delhi factory.
Why Every Indian Home Needs a Water Softener for Home Tank
Hard water is silently and expensively destroying millions of Indian homes. Particularly in Delhi NCR, Gujarat, Maharashtra, and Rajasthan, households draw water from borewells or municipal sources with hardness levels exceeding 300 ppm as CaCO₃. This excess calcium and magnesium causes limescale buildup inside geysers, washing machines, overhead storage tanks, and PVC pipes — reducing appliance efficiency significantly and dramatically shortening their useful working life. Most families replace geysers far sooner than necessary because they never addressed the root cause: hard water entering the home.
Installing a quality water softener for home tank at the point of entry is the smartest long-term investment any Indian homeowner can make. Unlike a point-of-use purifier that treats only drinking water at a single tap, a whole-home softener treats all water entering your property at the source — so every tap, shower, washing machine, dishwasher, and toilet benefits from soft, scale-free water simultaneously. The results are visible within days: bathroom tiles stay clean longer, geysers heat water faster using less electricity, clothes emerge from the washing machine feeling softer and looking brighter, and your hair and skin feel noticeably healthier after bathing.
Kita Systems manufactures and installs tank-mounted and inline water softeners in multiple capacities — from compact 25 LPH units for apartments to high-flow 1000 LPH systems for large housing societies and commercial premises across India. Our systems use certified food-grade cation exchange resin beads that swap calcium and magnesium ions for harmless sodium ions in a fully automatic process. Regeneration requires only common kitchen salt added to the brine tank — the system self-regenerates automatically during off-peak hours, requiring virtually no daily attention from the homeowner.
Signs Your Home Has a Serious Hard Water Problem
Watch for white chalky residue on taps, showerheads, and bathroom tiles — that is limescale deposited directly from hard water. Other indicators include reduced water pressure in older pipes, a geyser that takes noticeably longer to heat water, unusually frequent washing machine service calls, dry and itchy skin after bathing, and dull stiff laundry even when using premium detergent. A TDS meter reading above 300 ppm combined with a water hardness test result above 150 ppm CaCO₃ is conclusive evidence. Kita Systems offers a completely free water quality testing service at your home — our engineer tests your water on the spot and recommends the exact solution you need at zero cost.
Kita Systems: Certified Carbon Filter Manufacturers in India
Activated carbon has been trusted for water purification for centuries, and modern engineering has refined its effectiveness dramatically. Today, activated carbon filtration forms an essential stage in virtually every multi-stage water treatment system — from domestic under-sink purifiers to large municipal treatment plants. As ISO-certified carbon filter manufacturers in India, Kita Systems produces a comprehensive range of activated carbon products for residential, commercial, and industrial applications nationwide.
Our carbon filters are manufactured using premium coconut shell activated carbon, which delivers a BET surface area exceeding 1000 m²/g — making it extraordinarily effective at adsorbing chlorine, chloramines, pesticides, herbicides, volatile organic compounds (VOCs), and the compounds responsible for bad taste and unpleasant odour in water. Municipal water authorities routinely add chlorine for disinfection — but chlorine reacts with naturally present organic matter to form harmful disinfection by-products (DBPs) such as trihalomethanes, classified as potential carcinogens with long-term exposure. Our activated carbon filters eliminate these threats completely before water enters your home or reaches your RO membrane, protecting both your health and your purifier investment.
We supply carbon filter housings, replaceable cartridges, and bulk granular activated carbon (GAC) media to water treatment OEMs, apartment complexes, five-star hotels, hospitals, pharmaceutical manufacturers, and food processing facilities across India. All products are manufactured at our ISO-certified facility in Sonia Vihar, Delhi and comply with NSF/ANSI Standard 61 for drinking water system components. We also design and manufacture custom-specification carbon filter assemblies in stainless steel, food-grade polypropylene, and FRP materials for industrial clients with precise application requirements.
Our Carbon Filter Product Range
Our manufacturing catalogue covers the full spectrum of activated carbon filtration needs: 5-micron spun PP sediment pre-filters, standard 10-inch and 20-inch GAC cartridges, high-performance carbon block filters for sub-micron filtration, big blue filter housings in 10" and 20" configurations for high-flow commercial applications, and complete multi-cartridge filter assemblies for industrial water treatment lines. Bulk carbon media is available in 1 kg, 5 kg, 25 kg, and jumbo bag formats for large-scale industrial users. Our technical team works directly with clients to specify the correct carbon type, contact time requirement, and housing configuration for each unique application.
