I am using Kent grand RO+ UV+ UF water purifier in my home. I bought it at Rs. 16500. It is having the perfect capacity for a family of 4-5 persons. It has a capacity of 8 L. It’s filtration capacity is 15 litres per hour. It uses reverse osmosis to filter out contaminants and even ions. Along with this, it uses ultra violet technology to kill the pathogens and microbes present in water. It has total dissolved salts reduction capacity of 90 percent giving us the best quality drinking water and ensures health safety. It is fully automatic with auto on and auto off feature. Just connect it to water tap. The tank is made up of ABS food grade plastic. Power requirement is 60 w. Go for it. When it is a matter of health safety, choose Kent
