What to consider before buying a dehumidifier
Room size and extraction capacity
Match the machine to the space and the damp load. A 10–12L/day compressor model suits most flats and smaller homes, while 20L and above makes sense for larger houses, serious condensation or regular indoor laundry drying. Remember that headline extraction figures are measured at 30°C and 80% relative humidity — real-world extraction in a cool British home will be lower.
Compressor vs desiccant
Compressor (refrigerant) dehumidifiers are the default choice for heated living spaces: they extract more per watt in normal room temperatures. Desiccant models use a moisture-absorbing rotor instead, cost more to run, but keep working effectively in cold conditions where compressor models lose efficiency.
Operating temperature
If the machine will live in a garage, conservatory, caravan, boat or unheated utility room, check the minimum operating temperature. Compressor models lose efficiency below roughly 15°C and can stop extracting altogether in the cold; desiccant units typically keep working down to around 1°C.
Laundry drying
A dedicated laundry mode runs the fan and extraction continuously to dry clothes faster and keep that moisture out of your walls. If you regularly dry washing indoors, this feature alone can justify the machine — and it is generally cheaper per load than a tumble dryer.
Noise
Dehumidifiers run for hours at a time, so noise matters. For bedrooms and living rooms look for figures around 35–40 dB on lower settings; louder machines are better placed in hallways or utility rooms. Desiccant models have no compressor, but their fan noise is constant.
Running costs
Check the wattage before you buy: compressor models typically draw around 150–350W depending on capacity, while desiccant units can draw considerably more. An accurate humidistat that switches the machine off once your target humidity is reached makes a real difference to the electricity bill.
Tank size and continuous drainage
A tank of around 2.5L or more means fewer trips to empty it, and every machine stops when the tank is full. If you need round-the-clock extraction — or the unit will sit somewhere you visit rarely — look for a continuous drainage hose option so it can run unattended.
Humidistat and smart controls
An automatic humidistat lets you set a target humidity and leave the machine to manage itself — far more efficient than running it constantly. Wi-Fi app control adds scheduling and remote monitoring, which is genuinely useful for second homes, garages and utility spaces, but not essential for everyone.
Frequently asked questions
Match the extraction capacity to the space and the severity of the damp. As a rough guide, a 10–12L/day compressor model suits flats, bedrooms and smaller homes, while 20L or more makes sense for larger houses, serious condensation or regular indoor laundry drying. Headline figures are measured at 30°C and 80% relative humidity, so real-world extraction in a cool UK home will be lower — when in doubt, size up.
