The Zed Systems – Harmony is a wall-mounted RO and UV water purifier with a 12-litre storage capacity. It is designed for home use and includes a smart indicator for operational status. The product description is somewhat ambiguous, also referring to it as an “advanced, integrated solution designed to streamline operations,” which may suggest the brand name is used across different product categories. For the purpose of water purification, it offers a standard combination of RO and UV technology in a sizable unit.
