Which is the best water purifier for hard water in India?

KENT RO water purifiers are considered the best for hard water in India. They use a multi-stage purification process of RO+UV+UF+TDS Control, which effectively removes dissolved impurities like arsenic, rust, and pesticides from hard water while retaining essential natural minerals.

Does KENT RO waste a lot of water?

No, KENT features proprietary Zero Water Wastage Technology. It recirculates the rejected water to the overhead tank using its own pump, ensuring that no drop of water is wasted during the purification process.

What is the difference between RO, UV, and UF purification?

RO (Reverse Osmosis) removes dissolved impurities and heavy metals. UV (Ultraviolet) deactivates bacteria and viruses. UF (Ultrafiltration) removes physical impurities and cysts. KENT purifiers combine all three (RO+UV+UF) to provide 100% pure and safe drinking water.

Is KENT an Indian company?

Yes, KENT RO Systems Ltd. is a 100% Indian company founded in 1999 by Dr. Mahesh Gupta, an IIT Kanpur alumnus. It is headquartered in Noida, Uttar Pradesh, and manufactures its products in India.
