This summer's heat hasn't just been hot — a lot of it has been humid. France and Western Europe have spent long stretches under a heat dome pushing temperatures into the low-to-mid 40s°Cs, and the UK's run of heatwaves since May has come with the kind of muggy, tropical-night air that makes a room feel damp even with the windows open. If you've also been running an evaporative air cooler indoors — which adds moisture to the air by design — or drying laundry inside because it's too hot to think about the tumble dryer, that dampness compounds fast.
How to tell if it's actually a humidity problem
Condensation on windows, a musty smell, damp patches in corners, or laundry that never quite dries are all signs the air itself is holding too much moisture — not something a fan or an open window reliably fixes on its own.
For a bedroom or wardrobe
The Mini Dehumidifier with Colour-Changing Light is built for bedrooms, bathrooms and wardrobes where noise matters — it runs without the compressor whir you'd get from a bigger unit, so it won't disturb sleep.
For rooms that need fewer refills
If you're emptying a small tank every day, the Mini Dehumidifier with 2.2L Tank holds enough water to go longer between trips to the sink, while still running under 50 dB.
For basements, utility rooms and north-facing spaces
The rooms that stay damp all year — basements, utility rooms, north-facing bedrooms — need more capacity. The 2-in-1 Dehumidifier & Air Purifier with Remote pulls up to 2.2 litres of moisture a day out of the air and filters it at the same time.
Running it alongside a cooler
If you're using one of our evaporative coolers to get through the heat, as covered in our guide to cooling a room without central AC, a dehumidifier running on the side keeps the room from tipping into that heavy, damp feeling that evaporative cooling can cause in an already humid summer.
Frequently Asked Questions
Will a dehumidifier make a room feel cooler?
Not directly — a dehumidifier removes moisture, not heat. But humid air feels hotter than dry air at the same temperature, so pulling moisture out often makes a room feel noticeably more comfortable even if the thermometer reading barely moves.
How do I know what size dehumidifier I need?
Match tank capacity and extraction rate to the room and how damp it gets. Small bedrooms or wardrobes are fine with a compact unit, while basements or utility rooms that stay damp year-round need a higher-capacity model like our 2-in-1 Dehumidifier & Air Purifier.
Can I run a dehumidifier and an evaporative air cooler in the same room?
Yes. Since evaporative coolers add moisture to the air by design, running a dehumidifier alongside one helps stop a room from feeling heavy or damp during long stretches of use.
How often do I need to empty a dehumidifier's water tank?
It depends on tank size and how humid the room is. A larger tank, like our 2.2L model, means fewer trips to empty it, especially in consistently damp spaces.
