Installed in living rooms or offices to purify indoor air and control humidity, this humidifier disperses ultrafine 0.1 nm particles, which inhibit growth of microbes and remove the need for humidifier disinfectants. The top water-feeding system, fitted with a no-power, buoy-type indicator bar, allows you to pour water directly into the top grill. Taking the motif from “The Giving Tree”, a children's book, the system emits antimicrobials and phytoncides from the inner terpene module, creating a “bathing in the woods” environment with aromatherapy effects. It is also made of recyclable ABS.
