The new Zero-B Intello is a first of its kind with a customized electronic process monitor. This special feature informs the user of the quality of water, flow rate of water , total water consumed and an early warning on the remaining life of the filter elements for planned replacement. This steel finish version is specifically meant for designer kitchens where the compact Zero-B Intello can be placed under the counter/sink. Zero-B Intello uses Reverse Osmosis (RO), a worldwide effective technology. In this process water under pressure is passed through a semipermeable membrane with specific molecular weight cut-off and the small pore size of 0.001 micron . Purified water is collected for use in tank and impure water is flushed to the drain.
