The Beurer LB 37 Ultrasound Air Humidifier is a 2-in-1 cool mist humidifier and essential oil aroma diffuser, designed to add moisture to dry indoor air and, when you choose to, gently scent the room at the same time. Using ultrasonic technology, it releases a fine cool mist rather than warm steam, making it a practical option for bedrooms, baby and children's rooms, studies and living areas of up to 20 m². This listing is for the Toffee colourway (the LB 37 is also available in white).
Indoor air often dries out during the colder months when heating is running, and dry air can leave skin, eyes and airways feeling irritated. The LB 37 is designed to help raise humidity back towards a comfortable level so your space feels less parched. Because it doubles as a diffuser, you can add a few drops of your favourite essential oil to one of the included aroma pads for a scented, calming atmosphere — separate from the water, so the mist and the aroma stay independent.
How it works
- Ultrasonic cool mist: A vibrating membrane turns water into a fine, cool mist, so there's no heating element and no hot steam — helpful for a nursery where a burn hazard from warm-steam units is a concern.
- Separate aroma diffusion: Essential oils go onto an aroma pad in a dedicated compartment, never into the water tank, so the fragrance is dispersed without affecting the humidifier mechanism.
- Two mist levels: You can adjust the output between two spray levels to suit the room and how dry the air is, from a gentle haze to a stronger mist (up to 200 ml/h).
- Auto shut-off: The device switches off automatically once the 2-litre tank runs dry, so it won't keep running empty.
Built for a sleep environment
Quiet operation at approximately 35 dB and a night mode that dims the lighting make the LB 37 suited to running through the night without bright lights or noise disturbing sleep. The 2-litre removable tank is sized for medium rooms and gives you hours of continuous mist between refills, while low power consumption of around 20 W keeps it economical to run. It's a compact unit (13 x 21 x 25.5 cm, 810 g) with a 1.5 m cable and 100–240 V input, and it's backed by a 36-month Beurer warranty.
How to use the aroma function
- Choose a natural essential oil that is compatible with the device.
- Place a few drops onto one of the 15 included aroma pads.
- Put the pad into the dedicated aromatherapy compartment — never add oil to the water tank.
Additional aroma pads can be purchased separately when you'd like to swap scents.

Disclaimer
Never add essential oils or fragrances to the water tank — this can cause the ultrasound membrane to seize and damage the device. Aromas belong only on the aroma pads. Maintaining indoor humidity within roughly 40–60% is generally recommended; do not exceed 60%. Use fresh drinking water below 40 °C; if your water is very hard, use distilled water or the optional anti-limescale filter to reduce scale and white dust. Essential oils vary, and a diffuser being compatible with the device does not mean every oil is suitable around babies, young children, pregnant people or pets — use them with care and discretion. The LB 37 is CE certified and, per the supplier, holds regulatory certification in the European Union and with SAHPRA in South Africa. This appliance supports indoor air comfort and is not a treatment for any respiratory, allergy or other health condition.
Pandylane Pro Tips
Pandylane Pro Tip: Place the humidifier on a raised, stable, level and water-resistant surface such as a table rather than on the floor, and keep the mist pointed away from curtains, carpets and other objects that could get damp — the immediate area around the unit can become moist during continuous use.
