Home dehumidifier designed to cut moisture, prevent mould and speed laundry drying while using minimal energy. For households battling condensation, musty smells and slow-drying clothes, Honeywell Dehumidifier promises quieter operation and easy humidity control. Is the combination of low running costs, compact size and smart controls right for a small British home?

⚡ At a Glance
  • Dehumidification Performance: Removes up to 12 litres per day with operation at 40–42.5 dB
  • Best for: Small 2–3 bedroom houses or flats and regular laundry drying
  • Not ideal for: Large homes or commercial spaces requiring higher extraction capacity

Compact, wheeled design combines a 2.5 litre detachable tank with a removable hose for continuous drainage. Digital controls include adjustable humidity settings and an intelligent comfort mode for straightforward operation.


Low running costs – thanks to optimised energy consumption

Energy-efficient operation is specified at a running cost of approximately 5p per hour based on 25p/kWh and uses eco-friendly R290 refrigerant. Internal components and optimisation reduce power draw during normal dehumidification cycles.

Lower overnight or long-run costs make prolonged use practical, ideal for damp periods and continuous humidity control. Households that run the unit regularly will notice reduced energy waste compared with higher-consumption alternatives.

Faster laundry drying – with a dedicated laundry mode and higher fan speed

One-click clothes drying mode raises fan speed to increase airflow and uses a 24-hour timer and auto humidity sensor to regulate runtime. Auto defrost protects refrigeration components during cooler, damp conditions.

Laundry dries more quickly and more cost effectively than using a tumble dryer for every load, especially helpful on wet British days. Timed runs let drying occur when convenient without constant supervision.

Simple humidity control and low maintenance – with digital display, sensor and washable filter

Adjustable humidity control spans 30–90% in 5% increments and an intelligent comfort mode alters dehumidification automatically. A washable dust filter includes a cleaning alert and the 2.5 litre tank has a full-capacity alert plus a removable hose for continuous drainage.

Precise humidity targets make it easy to prevent condensation and mould while avoiding over-drying rooms. Filter cleaning and optional continuous drainage keep maintenance straightforward for busy households.
