Water quality in India is one of the most pressing everyday concerns for modern families. Invisible contaminants — from dissolved heavy metals in borewell groundwater, to chlorine by-products in municipal supply, to limescale from hard water — affect millions of households daily. At Kita Systems, over 12 years of manufacturing experience in Delhi has given us a deep, practical understanding of India's water challenges and the solutions that genuinely work.
Choosing the Best Domestic Water Purifier in India
India's water supply varies dramatically from state to state and even neighbourhood to neighbourhood. In Delhi, Haryana, and Rajasthan, groundwater often contains TDS levels exceeding 500 ppm alongside fluoride, nitrates, and traces of heavy metals. Coastal cities face saltwater intrusion. Urban homes deal with recontamination through ageing pipeline networks. Understanding this reality is what separates a truly effective water purifier from one that merely looks good on a specification sheet.
When evaluating options for the best domestic water purifier in India, the most critical consideration is matching the purification technology to your exact water source. Reverse Osmosis (RO) systems remain the gold standard for Indian conditions — the semi-permeable membrane blocks dissolved salts, heavy metals, bacteria, viruses, and agricultural chemicals in a single powerful stage. For TDS levels above 200 ppm, an RO purifier is not optional; it is essential.
"The best water purifier is not the most expensive one — it is the one precisely matched to your water source, your household's needs, and properly maintained over time."
Kita Systems' domestic RO range combines RO filtration with UV disinfection and a precision TDS controller that retains essential calcium and magnesium minerals. Every purifier is engineered specifically for Indian electrical conditions — with inbuilt voltage surge protection, energy-efficient pump motors, and quick-release filter cartridges that make annual maintenance straightforward and affordable.
Why Every Indian Home Needs a Water Softener for Home Tank
Hard water is the most expensive hidden problem in millions of Indian homes. States like Delhi, Rajasthan, Gujarat, Haryana, and parts of Maharashtra have groundwater hardness routinely exceeding 300–500 ppm CaCO₃. The calcium and magnesium ions that cause this hardness create stubborn limescale deposits inside geysers, washing machines, overhead tanks, and PVC pipes — reducing heating efficiency, blocking water flow, and dramatically shortening the useful life of appliances.
Installing a water softener for home tank at the point of entry is the most comprehensive and cost-effective solution available. Unlike a kitchen purifier that treats only drinking water at a single tap, a tank-mounted softener treats all water entering your property — every tap, shower, washing machine, toilet, and pipe benefits simultaneously. Within days of installation, families notice that bathroom tiles stay cleaner, showerheads stop clogging, the geyser heats water faster, laundry emerges brighter and softer, and skin and hair feel noticeably healthier after bathing.
Kita Systems manufactures tank-mounted and inline water softeners in capacities from 25 LPH for compact apartments to 1000 LPH for large housing societies. Our systems use certified food-grade cation exchange resin — automatic regeneration requires only common kitchen salt, making day-to-day operation virtually maintenance-free.
Kita Systems: Certified Carbon Filter Manufacturers in India
Activated carbon filtration is one of the oldest, most proven methods of water purification. Every multi-stage water purifier, every commercial water treatment system, and many industrial processes rely on activated carbon as an essential filtration stage. As ISO-certified carbon filter manufacturers in India, Kita Systems produces a comprehensive range of activated carbon products for residential, commercial, and industrial clients across the nation.
Our carbon filters are manufactured using premium coconut shell activated carbon — selected for its extraordinary surface area exceeding 1,000 m²/g, which makes it highly effective at adsorbing chlorine, chloramines, pesticides, herbicides, volatile organic compounds (VOCs), and compounds responsible for unpleasant taste and odour. We supply to water treatment OEMs, hospital systems, hotel chains, pharmaceutical manufacturers, food processing plants, and apartment complexes across India.
All products are manufactured at our ISO 9001:2015 certified facility in Sonia Vihar, Delhi, and comply with NSF/ANSI Standard 61. We also manufacture custom carbon filter assemblies in stainless steel, food-grade PP, and FRP for industrial clients with specific flow requirements.
