Dry clothes faster.
Cut drying time without overloading your heating. Laundry Mode increases airflow to pull moisture from clothes faster, helping them dry in hours, not overnight. It's cheaper, neater, and won't fog up your windows.
Place your dehumidifier near the drying rack, leave the door ajar, and let it do the hard work – without turning your home into a sauna.
Pro tips:
Space clothes out – airflow matters more than heat.
Short, focused cycles work best.
Use a timer to catch off-peak hours.
Dehumidifiers with Wi-Fi.
Take full control from your phone. Smart dehumidifiers let you set cycles remotely, hit your target humidity, and get full-tank or filter alerts before performance dips.
Perfect for drying laundry while you’re out, catching off-peak energy windows, and keeping rooms at 50–55% RH – without the guesswork.
Best for:
Automated schedules and off-peak control.
Remote checks for garages, rentals and spare rooms.
Alerts before tank overflows or filters clog.
DESICCANT DEHUMIDIFIERS
Ideal for colder environments.
Compressor units can struggle in colder spaces, but this is where desiccant dehumidifiers excel. They extract moisture efficiently even in low temperatures, releasing a gentle stream of warm air while they work.
Perfect for unheated rooms like garages, lofts, and conservatories. If your space dips near single digits in winter, this is your go-to.
Why choose desiccant?
Works reliably in cold rooms.
Gentle warmth + quiet operation (max 50dB). Laundry, Sleep & Auto modes.
Filters dust as well as moisture. Compact and easy to move.

DEHUMIDIFIER FAQs
What size dehumidifier do I need?
That depends on two things: room size and how much moisture you're dealing with.
-
Small rooms or flats: start with a 10–12L model.
-
Laundry, large households, or whole-home use: go 15–20L+
-
Unheated spaces (e.g. garages, conservatories): always choose desiccant, regardless of size.
Still unsure? Use our Dehumidifier Buying Guide to match capacity to your space.
Where should I place my dehumidifier?
Place it as close to the moisture source as possible – think drying rack, bathroom door, or foggy window.
-
Leave at least 20cm around the unit so air can circulate.
-
Keep internal doors ajar for full room drying.
-
Avoid placing it behind curtains, against walls or near soft furnishings.
Which is better: compressor or desiccant?
That depends on where you’ll use it – and how warm the space is.
-
Warm rooms (15°C+) → Compressor (more energy-efficient)
- Cold spaces (<15°C) → Desiccant (consistent performance + gentle heat)
Quick rule: If it’s winter and the room feels cold, go desiccant.
How much do dehumidifiers cost to run?
Most dehumidifiers cost pennies per hour, especially when used in short, focused bursts rather than running constantly.
-
A typical 12L model costs around 5–10p per hour, depending on your tariff.
-
Larger or desiccant units may use more power but often run for shorter periods.

Do I need a Wi-Fi dehumidifier?
If you’ll use the app, yes, it’s genuinely useful.
- Turn it on/off from your phone.
- Set precise humidity targets.
- Schedule Laundry Mode while you’re out.
- Get alerts when the tank’s full.
But if you’ll never open the app? Save the budget. Go for a bigger capacity or quieter model instead.
