The ZeroB AutoSoft 6 is a fully automatic hard water softener that treats water at 6000 litres per hour and handles incoming hardness up to 800 ppm. It uses 90 litres of purple resin media, holds 200kg of salt, and consumes 14kg per recharge cycle the largest of ZeroB's AutoSoft range.
6000 LPH for homes where a lot of water moves at once. Flow rate is what decides whether a softener keeps up under real demand. At 6000 LPH, this is double the AutoSoft 3's capacity and suits a large house with multiple bathrooms running simultaneously, a joint family, a small guest house, or a light commercial setting. If your household regularly has several showers and taps open together, a softener sized below your peak flow will struggle and your pressure will drop; the AS6 is built for that load. For a normal-sized home, the AS3 at 3000 LPH is the more economical fit tell our team your bathroom count and household size and we will size it properly.
800 ppm inlet hardness. This unit treats water up to 800 ppm (as CaCO₃), which covers the moderately-to-quite-hard supply common across Bangalore, Hyderabad, and most borewell-fed areas. Get your water tested before ordering if it reads under 800 ppm, this unit will treat it properly.
What hard water is doing to your home. If your supply is borewell or municipal-hard, you already see it: soap that will not lather, scum on tiles and taps, white scaling on your shower and geyser, stiff laundry, dry skin and hair. That same scaling is building inside your water heater, washing machine, and plumbing, shortening the life of every appliance water touches. A softener removes the hardness minerals before the water reaches any of it.
What softening changes day to day. Softened water lathers properly, so you use less soap, shampoo, and detergent. Bathing feels different immediately no film on the skin, hair that rinses clean. Laundry comes out softer. Scum stops forming on bathroom surfaces, and the scaling that ruins geysers and washing machines stops accumulating.
Running cost 14kg of salt per recharge from a 200kg reservoir. Salt consumption scales with capacity (7kg on the AS3, 14kg here), and the large 200kg reservoir means long intervals between refills even at this size. Over the years a softener runs, salt is where the real ongoing cost sits.
Fully automatic nothing to operate. The programmable process valve runs the regeneration cycle automatically, so the resin recharges itself on schedule. You top up the salt; the system handles the rest.
SolarClue is India's managed solar marketplace, and we supply the water treatment equipment hard-water homes need. Our team checks your water hardness against the 800 ppm limit and confirms the flow rate suits your peak household demand before recommending a size undersize a softener and your pressure drops when the house is busy. If you are also choosing a solar water heater, your water hardness decides which tank you need; we match the two together.
