A system is capable of air cleaning and dehumidifying, and includes a condenser device, a water supplying device and an oxyhydrogen ion generating device. The condenser device is operable to form water vapor in ambient air into water droplets. The water supplying device collects the water droplets from the condenser device. The oxyhydrogen ion generating device is coupled to the water supplying device and includes a container receiving water from the water supplying device, electrode plates disposed in the container, and an output conduit. The electrode plates are operable to electrolytically convert water to form oxyhydrogen-ion-containing gas that is released via the output conduit.
