Setup: Beurer Air Dehumidifier LE 150 User Manual

Introduction — beurer Air Dehumidifier LE 150: overview, benefits and use cases

The beurer Air Dehumidifier LE 150 is a compact, 12‑litre‑per‑day refrigerant dehumidifier designed to improve indoor air quality in small to medium rooms (up to ~30 m²) by removing excess moisture, preventing mould and accelerating laundry drying. Manufacturer specifications highlight an automatic humidity control (maintains 45–55% RH in Auto), a selectable setpoint range (30–80% RH), a dedicated laundry‑drying function, a 2.0–2.4 L removable water tank with overflow protection and an external condensate drain option, plus night mode for quiet operation.

Key benefits and unique selling points include efficient continuous dehumidification up to 12 L/24h, energy‑efficient operation with eco‑friendly R290 refrigerant, portability with castors and a carrying handle, and practical features such as a digital humidity display, 1–24 h timer and washable pre‑filter. Typical target users are apartment or house owners, tenants, renters with damp bathrooms or basements, people who dry laundry indoors, and those looking to prevent condensation and mould in rooms up to ~30 m².

Common use cases: year‑round moisture control in living rooms, bathrooms, cellars and utility rooms; temporary moisture removal after renovations; faster indoor drying of laundry using the Laundry Drying mode; and continuous dehumidification in poorly ventilated spaces. Estimated retail price (range depends on country and retailer) typically falls in the lower‑mid consumer dehumidifier segment — retailers list the LE 150 in the roughly mid‑to‑low hundreds (local currency) with standard warranties and occasional offers from resellers.

Continuous Dehumidification

In continuous dehumidification mode, the room is dehumidified without interruption. To switch on continuous dehumidification mode, press the humidity button (22) repeatedly until "--" appears on the display. The continuous operation symbol (15) lights up.

Dehumidification with Target Humidity

In dehumidification with target humidity mode, the room is dehumidified only up to a preset target value (e.g., 50% humidity). The device stops dehumidifying the air once the preset target value has been reached.

Setting a Special Mode

The device has three optional special modes that you can select if desired.

• Sleep mode
• Laundry drying mode for clothes
• Automatic mode

Sleep Mode

Sleep mode automatically sets the low fan speed (18) and switches off all LEDs and button tones to ensure a restful night's sleep without disturbances. The target humidity can still be adjusted in sleep mode. To switch on sleep mode, press the sleep/laundry drying button (25). The sleep symbol (12) lights up for 3 seconds and then dims. All other LEDs and button tones are switched off.

Laundry Drying Mode for Clothes

The device has a special laundry drying mode for when you want to dry clothes indoors and counteract the resulting humidity. It also enables the clothes to dry faster. This laundry drying mode automatically sets the high fan speed (19) and continuous dehumidification. You cannot set a target humidity in this mode.

Automatic Mode

In automatic mode, the air in the room is automatically dehumidified so that the humidity remains between 45% and 55%.

1. To switch on automatic mode, press the automatic button (24). The automatic symbol (14) lights up.
2. To switch between the low (18) and high (19) fan speeds, press the fan speed button (23) when the air dehumidifier is on.
3. To switch off automatic mode, press the automatic button (24) again. The automatic symbol (14) goes out.

Setting the Timer

The air dehumidifier features a timer function that allows you to determine after how many hours the device should automatically switch off (when in operation) or switch on.

1. Use the timer button (26) to select your desired timer duration. You can select a duration between 1 and 24 hours in increments of 1 hour. The selected timer duration appears on the display. Once the set timer duration has flashed five times, it is confirmed, and the timer symbol (11) lights up. The display then shows the current humidity level again.
2. To view the remaining timer duration while the device is running, press the timer button (26). The display briefly shows the remaining time in hours before the air dehumidifier switches off.
3. To switch off the timer, press the timer button (26) repeatedly until the display shows "00".

Switch-Off Time

Press the timer button (26) while the device is running to set the switch-off time. The device will switch off after the selected time period.

Switch-On Time

Press the timer button (26) while the device is switched off to set the switch-on time. The device will switch on after the selected time period.

Humidity Indicator

The humidity indicator (5) shows the current ambient humidity level on the device.

• Low Humidity: Below 45% — The humidity indicator is blue.
• Optimum Humidity: 45–65% — The humidity indicator is green.
• High Humidity: Above 65% — The humidity indicator is red.

Defrost Function

• If the device is operated in an environment with low temperatures, frost may form inside the device. To ensure proper operation, the air dehumidifier features a defrost function.
• If the temperature is between 5°C and 16°C, the device automatically starts the defrost function for 10 minutes.
• The ON/OFF symbol (17) flashes on the display while the defrost function is running.
• Once the 10 minutes have elapsed, the device continues running normally for 60 minutes.

Emptying the Water Tank

If the water tank (1) is full, the water level symbol (20) will light up red, and the device will automatically stop running. An acoustic signal will sound (except in sleep mode), and the message "FL" will appear on the display. To empty the water tank (1), proceed as follows:

• Press the ON/OFF button (21) to switch off the air dehumidifier.
  • All LEDs except the ON/OFF symbol (17) go out.
• Carefully pull the water tank (1) backwards using the recessed handles at the sides.
• Empty the water tank (1) through the tank outlet.

• Check that the float can move freely before reinserting the tank. The float must not be blocked. If the float is blocked, this can cause an incorrect water level to be shown on the display ("FL" for a full water tank).

Condensate Hose

If you want the device to run continuously, connect the supplied condensate hose (9) to the device. The condensate can automatically drain into a sufficiently sized collection container or a suitable drain.

CLEANING, CARE AND MAINTENANCE

• Before performing any cleaning or maintenance work, always ensure that the mains plug of the device has been properly disconnected.
• Always store the device in its original packaging. Only store the device in an upright position. Do not place any objects on the device.
• Store the device in a well-ventilated room that measures at least 4 m².
• Store the device in dry conditions and protect it from frost and heat.

2. Rinse out the water tank with clean water every 2 weeks. If the device is used very intensively, clean the water tank more frequently. If necessary, remove any deposits in the water tank using a plastic brush.

Cleaning the Air Filter

We recommend cleaning the air filter (6) every 14 days, as dust can collect there and restrict airflow. Do not operate the device without the air filter (6) installed.

1. Pull out the water tank (1).
2. Remove the air filter (6).

Troubleshooting

Pros & Cons — honest assessment of the beurer Air Dehumidifier LE 150

• Pros — Efficient, practical features

  - Removes up to 12 L/day (suitable for rooms ≈30 m²), making it effective for typical living spaces and damp bathrooms.

  - Laundry drying function speeds up indoor clothes drying compared with basic dehumidifiers, useful in colder months or apartments without outdoor drying.

  - Portable design: carrying handle, castors and a 2.5 m power cable improve placement flexibility and ease of use.

  - Environmental benefit: uses R290 refrigerant (lower GWP) where regionally compliant.

• Cons — limitations & tradeoffs

  - Small water tank (≈2.0–2.4 L) requires regular emptying unless you use the external condensate drain, which may be inconvenient in some setups.

  - With a stated dehumidification of 12 L/24h, performance is conditional (measurement at 30°C/80% RH); in cooler or less humid conditions, the actual extraction will be lower, so larger damp spaces may need a higher‑capacity unit.

  - Basic control set (2 fan speeds) means fewer fine‑tuning options vs. premium models that offer multiple fan speeds or smart app integration.

  - Some competitors offer larger tank capacity or Wi‑Fi control at similar price points, so value for money depends on feature priorities (quiet/night mode and R290 are advantages here).
