The Exo Terra EX Air Humidifier is an ultrasonic mist generator designed to maintain optimal humidity levels in terrarium environments. This black plastic unit produces a fine, cool mist with adjustable output density, capable of reaching up to 100 percent relative humidity for tropical or desert microclimates. The humidifier features a generous 4.5-liter transparent water tank with an LED water level indicator, allowing for long operating times between refills. Utilizing whisper-quiet ultrasonic technology, the device operates without disruptive noises or the need for batteries. The unit measures 17 × 17 × 37 cm and includes a flexible 120 cm hose for versatile placement options, enabling connection to single or multiple terrariums. An automatic dry run protection ensures that the device shuts off when the water level becomes too low, extending the lifespan of the evaporator. Designed for placement outside the terrarium on flat surfaces, the included hose can be routed through ventilation openings to target specific areas for mist or dew formation. Operating on 230 V mains power and featuring an integrated design free of solar modules, this humidifier is suitable for moisture-loving reptiles, amphibians, and exotic plants. The adjustable mist output allows for customization to different terrarium types, while the clear operation enables unobtrusive observation of the inhabitants. Installation involves positioning the base unit on a stable surface and routing the supplied hose through terrarium openings for targeted mist distribution. This reliable humidity management solution combines practical functionality with durable construction for consistent environmental control in reptile and amphibian habitats.
