The ZeroB AutoSoft 3 is a fully automatic hard water softener that treats water at 3000 litres per hour and handles incoming hardness up to 800 ppm. It uses 45 litres of purple resin media, holds 200kg of salt, and consumes just 7kg per recharge cycle.
Two numbers decide whether a softener suits your home, and this one states both. Flow rate determines whether the softener can keep up when several taps and showers run at once at 3000 LPH, the AutoSoft 3 handles simultaneous demand across a normal household without pressure dropping. Inlet hardness capacity determines whether it can actually treat your water at 800 ppm (as CaCO₃), it covers the moderately-to-quite-hard supply common across Bangalore, Hyderabad, and most borewell-fed areas. Get your water tested, and 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 up inside your water heater, washing machine, and plumbing, shortening the life of every appliance water touches. A softener stops the cause rather than treating symptoms it 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.
Very low running cost 7kg of salt per recharge from a 200kg reservoir. That is a large salt capacity with modest consumption per cycle, which means long intervals between refills and low ongoing cost. Over the years a softener runs, salt consumption is where the real cost sits, and this unit is efficient on it.
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.
