Dehumidifiers are far cheaper to run than most people expect. Running one for several hours each day can cost less than a coffee per week.
Understanding power use
Most compressor models use between two hundred and three hundred watts. At current electricity prices this works out at around six to ten pence per hour.
Why the cost varies
- Higher fan speed uses slightly more power.
- Cold and damp rooms cause the unit to work harder.
- Better models extract moisture faster which means shorter run time.
Tips to keep running costs low
- Use laundry mode only when drying clothes.
- Close windows so the warm moist air is not replaced with cold air.
- Keep the filter clean.
If running cost is a concern, focus on modern low energy models with good real world reviews. We have listed a few strong options below.
