❔Do dehumidifiers consume a lot of electricity?

Not as much as you might think. A typical Aktobis dehumidifier for domestic use consumes between 200 and 500 watts, depending on its size and settings. If it runs for several hours a day, the monthly costs are usually equivalent to those of a modern refrigerator.

For comparison:

🧊 Refrigerator: ~150-400 W
🧺 Washing machine (in operation): 500-2000 W (peak values during heating cycles)
🔥 Iron: 1000-2000 W

All our dehumidifier models have a built-in hygrostat built-in hygrostat which only switches them on when required.

You can also limit the costs by positioning the appliance to ensure maximum airflow.

👉 In most households, the electricity costs for a dehumidifier are moderate - especially compared to the potential costs of mould damage or poor air quality.
