This white, stylish device features a removable 2-liter water tank, two mist levels, and a dedicated night mode for quiet operation without bright lights—perfect for bedrooms.

Key benefits include alleviating dry skin, easing breathing, reducing dust concentration, and protecting eyes from dryness. Unique selling points are its aromatherapy function with 15 included aroma pads for essential oils, automatic shut-off when empty, and low 20-watt power consumption.

The Beurer Air Humidifier LB 37 operates quietly at around 35 dB, with LED indicators (blue for level 1 at 200 ml/h, white for level 2 at 150 ml/h, red for low water).

INITIAL USE

Unpacking the Device

Keep packaging material away from children! There is a choking hazard.

Open the cardboard packaging.
Remove the protective insert. Keep the plastic film closed.
Lift the device up and out of the packaging.
Remove the plastic covering.
Check the device, the mains plug and the cable for damage.

USAGE

Check the humidity of your ambient air regularly. Intensive continuous operation can cause the ambient air to become excessively humid. The relative air humidity should not exceed 60%.

Switching On the Device

Insert the plug into the mains socket.
If there is no or not enough water in the water tank, a red LED lights up. The device has switched off for safety reasons.
Fill the water tank as described under Section 6, Initial Use.

Switching Off the Device

Press the ON/OFF button 4 times. The LED lighting goes off.
Pull the plug out of the mains socket.

Installation

Before putting the device into operation, read the safety notes in the Safety chapter.

The immediate vicinity of the air humidifier can become damp.
Calcareous water can leave white deposits.
Do not place the device on the floor, but in a raised position (e.g. on a table or chest of drawers).
Position the device so that the mist outlet is not directed towards objects.
Empty any remaining water when the device is not in use.
Place the air humidifier on a firm, level and water-resistant surface. If the device should accidentally tip over, water may escape, even if the device is switched off and unplugged.

Filling the Water Tank

Lift the water tank and rotate it. The water tank is kept closed by means of a spring valve.
Open the screwed plug on the water tank.
Fill with water. The water tank holds a maximum of 2 litres.
Tightly close the water tank using the screwed plug.
Rotate the water tank and position it on the base unit. The tank should sit tightly on the base unit.

CLEANING AND MAINTENANCE

Regular cleaning and disinfection are a prerequisite for hygienic and fault-free operation. The level of contamination of the device depends on the water quality and how long it has been in operation. In any case, we recommend the following cleaning intervals. Cleaning the Ultrasound Membrane with a Brush, Rinsing the Base: Empty the water from the base unit via the side rim in the direction indicated by the arrow. Ensure that no water gets inside the device, e.g. via the fan opening.

Clean the ultrasound membrane using the cleaning brush provided.
Empty the water from the base unit via the side edge.
If dirty residue remains in the base unit, pour some clean, fresh water into the base unit and empty it out via the side edge.

Rinsing the Water Tank, Replacing the Water

Clean the water tank regularly, at least every three days if using daily.
Use a mild cleaning product or a citric acid or vinegar-based solution.
Clean the thread of the screwed plug using a soft brush.
Half-fill the water tank with water.
Tightly close the water tank using the screwed plug.
Shake the water tank by rocking it back and forth several times.
Empty out the water completely.
Repeat the process using clean, fresh water.

Cleaning the Air Humidifier Inside and Out

Empty the water from the base unit via the side edge.
Wipe the air humidifier with a damp cloth inside and out. Use only a mild detergent or citric acid or vinegar-based solution to perform cleaning work.

Descaling

Descaling the Ultrasound Membrane

Hard water can cause limescale to build up in the device and, especially, on the ultrasound membrane. This forms white deposits. Descale the device regularly.

Drop some descaling solution onto the ultrasound membrane.
Leave it to take effect for two to five minutes.
Clean the ultrasound membrane using the cleaning brush.
Rinse the base unit twice with clean, fresh water.

Cleaning Inside the Base Unit

Dip a damp, soft cloth briefly in descaling solution.
Use the cloth to wipe the inside of the base unit.
Carefully pour some clean, fresh water into the base unit.
Empty the water from the base unit via the side edge.
Repeat the process using clean, fresh water.

Descaling the Water Tank

Half-fill the water tank with descaling solution.
Tightly close the water tank using the screwed plug.
Shake the water tank by rocking it back and forth several times.
Empty the descaling solution completely.
Repeat the process twice using clean, fresh water.

ACCESSORIES AND REPLACEMENT PARTS

If the water is hard, we recommend using the optional anti-limescale filter.

Anti-Limescale Filter

Fitting the Anti-Limescale Filter

Lift the water tank and rotate it.
Open the screwed plug on the water tank.
Screw the anti-limescale filter onto the screwed plug on the inside.
Tightly close the water tank using the screwed plug.

Quiet night mode: Operates at ~35 dB with dimmed LEDs, perfect for undisturbed sleep—users report no noise disruption.
Aromatherapy versatility: Includes 15 pads for essential oils, doubling as a diffuser for relaxation and sinus relief.
User-friendly design: Removable 2L tank, auto shut-off, and cleaning brush make maintenance simple; fills for hours of mist.
Great value: At $50–$80 with a 3-year warranty, it outperforms basic models like cheaper no-name humidifiers in quietness and features.

Cons

Limited to 20 m² rooms: Not suitable for larger spaces; alternatives like Beurer's LB 88 cover bigger areas but cost more.
Mist output varies: Level 1 (200 ml/h) is stronger, but night mode (150 ml/h) may feel weaker in very dry conditions.
Requires regular cleaning: Ultrasound tech can build mineral deposits with hard water; the included brush helps, but weekly descaling is advised.

Overall, the Beurer Air Humidifier LB 37 offers excellent value for small-room use, balancing features and affordability against minor limitations.
