A. O. Smith has launched the Z3 Onyx Black, an under-sink RO water purifier featuring antioxidant water technology. The product offers an alternative to conventional countertop purifiers and includes a water recovery rate of up to 55%.
The Z3 combines eight-stage RO and UV purification with copper mineralisation and alkaline technology. According to the company, these features replenish minerals and enhance hydration. Its under-sink design also helps save kitchen counter space.
The purifier features a six-litre storage tank and can supply stored purified water without electricity, thanks to its hydropneumatic tank technology. It is also BPA-free and includes GlidePro™ wheels and a handle to simplify movement and maintenance.
