The Exo Terra Ultrasonic Humidifier generates a cool fog through ultrasonic oscillations, simulating low hanging clouds and fog in tropical terrariums or early morning dew in desert setups. It's designed for keepers who need reliable, adjustable humidity control outside of the enclosure.

With a large 4.5 liter (1.2 gallon) reservoir and adjustable fog output, the unit runs up to 20 hours per fill and is powerful enough to humidify multiple terrariums using the included Y-connector and 120cm flexible hose. A built-in LED indicator shows water level, and the unit automatically shuts off when the reservoir runs dry.

Ideal for geckos, chameleons, tree frogs, tortoises, and other reptile and amphibian species that require elevated humidity. Pairs well with the Exo Terra Thermostat & Hygrostat for automated day and night humidity cycles.
