DEERMA F628S Ultrasonic Humidifier, 5 Liter, White

The DEERMA F628S Ultrasonic Humidifier uses ultrasonic technology to produce a fine cool mist for indoor use. Its 5-litre removable water tank holds enough water for extended operation between refills. The unit runs at around 30 dB, keeping noise low enough for a bedroom or nursery. It draws 25 W during normal use. A built-in UV system treats the water before it is dispersed, which helps with overall air quality.

Button controls give direct access to the main settings. A digital display shows the current temperature and humidity. Automatic mode uses a built-in humidistat to hold relative humidity between 45% and 90%. Dedicated sleep and night modes dim the display for use in a dark room without affecting the climate control. The appliance does not support smartphone or tablet control and operates only through its onboard buttons. At 190 by 190 by 350 mm and 2.5 kg, the white housing fits easily into most rooms.

• Integrated aromatherapy compartment for essential oils
• Water-level indicator for when the tank needs refilling
• Automatic shut-off when the water tank is empty
• Three mist output settings
• 12-hour timer for scheduled, unattended use
