Humidifier Blaupunkt AHS902 Steam 4.5 L White 155 W

The Blaupunkt AHS902 Steam humidifier combines a 4.5 L water tank with 155 W power to provide continuous steam humidification for home environments. Designed in white with a black touch control panel and LED display, the device shows current humidity and ambient temperature and supports night mode to dim the screen. The humidifier supports Tuya smart home integration for remote control and notifications. Core functions include steam output up to 450 ml/h, a hot-mist option for water sterilisation, an integrated HEPA H13 filter with activated carbon, a resin filter to reduce water hardness, a negative ion generator and a built-in UVC lamp for additional microbial inactivation. The unit is lightweight and quiet in operation, with a humidistat for automatic control and a 12-hour timer and aromatherapy drawer for essential oils.

Advantages

The AHS902 offers precise humidity management via a built-in humidistat and an LED touch display that reports real-time humidity and temperature. Smart home compatibility through the Tuya app enables remote monitoring and alerts, such as low-water notifications. Multiple air treatment features—HEPA H13 filtration with carbon layer, negative ion generation and UVC lamp—work together with steam output to improve indoor air quality. A hot mist option sterilises the water and prevents cooling of the room while a 12-hour timer and quiet 30 dB operation make the device suitable for overnight use.

How to use

Fill the 4.5 L tank with clean water, place the unit on a stable, level surface and connect it to a 220–240 V outlet. Use the touch control panel or the Tuya app to set the desired humidity level or activate the humidistat for automatic operation. Choose steam or hot-mist mode as required; hot-mist mode will raise the water temperature for sterilisation and prevent room cooling. Replace or clean the HEPA H13 filter, resin filter and water reservoir according to the maintenance schedule and follow safety instructions before replacing the UVC lamp. Add a few drops of essential oil to the aromatherapy drawer if fragrance is desired. The device can be set with the 12-hour timer or left to run with automatic humidistat control.

Usage recommendations

Maintain recommended indoor relative humidity of 45%–60% to support comfort and health. Use distilled or low-mineral water to reduce scale buildup and extend filter life. Regularly clean the tank and replace filters per manufacturer guidance; when using the hot-mist or UVC functions, follow safety and servicing instructions to ensure effective sterilisation and safe operation.
