Frequently Asked Questions - AH3 ELRO
How do I clean the ELRO AH3 humidifier?
To clean your ELRO AH3, disconnect it from the power source and empty the water tank. Weekly cleaning is recommended to prevent mineral scale. Use a soft cloth dampened with vinegar and water, then rinse thoroughly. Avoid using detergents or abrasive materials.
Can I use tap water?
Yes, you can use cool tap water. For better results and less mineral buildup, distilled or demineralised water is recommended. Do not use hot water or water with additives.
Why is there no mist coming out?
Check if the device is properly assembled and the water tank is filled. Also ensure the mist outlet is not blocked. If the water level is below the minimum, the auto shut-off feature activates. Clean the transducer if mineral deposits have formed.
How much water does the tank hold?
The removable water tank holds up to 3 litres of water, offering long-lasting humidification. At medium output, it can run continuously for around 10 hours.
Is it safe to use overnight?
Yes, the ELRO AH3 is designed with safety features including auto shut-off when the water runs out. Its very low noise operation (<36 dB) makes it ideal for bedrooms. Always place the humidifier on a stable, level surface away from children.
How do I adjust the mist levels?
The touch control panel has mist level buttons. Press repeatedly to cycle through low, medium and high output. The LED display shows the current level. You can also set a timer (1-8 hours) by pressing the timer button.
What is the recommended room size?
The AH3 can cover rooms up to 30 m² depending on the mist level and room insulation. For larger spaces, place it centrally. Use the highest setting in bigger rooms.
Does it have a timer function?
Yes, the device includes a built-in timer that allows you to program automatic shutdown between 1 and 8 hours. This helps save energy and ensures safe operation.
Can I add essential oils to the water?
No, do not add essential oils or fragrances to the water tank. This can damage the ultrasonic transducer and the internal components. If required, use a separate aroma diffuser.
How do I replace or find spare parts?
Spare parts such as the water tank, mist nozzle and filter can be ordered through ELRO customer service or authorised dealers. Please keep the model number (AH3) handy when ordering. The parts are designed for easy replacement without special tools.
