All the information you need to know about dehumidifiers.
What is relative humidity?
Relative humidity is the percentage of moisture in the air compared to the maximum amount the air can hold at a specific temperature. When the air is warm, it can hold more water vapor; when it's cool, it holds less. For example, 70% relative humidity means the air contains 70% of the moisture it could potentially hold at that temperature. It’s a key factor in comfort, indoor air quality, and the effectiveness of appliances like dehumidifiers.
Where does the water come from?
The water in a dehumidifier comes from moisture in the air. As humid air passes through the unit, it cools down, causing water vapor to condense into liquid, which is then collected in a tank or drained away.
What is the ideal humidity level for my home?
The ideal humidity level for a home is typically between 40% and 60%. This range helps maintain comfort, prevents mold growth, and protects furniture and electronics. Levels below 40% can feel too dry, while levels above 60% may encourage dampness and allergens.
How does a dehumidifier work?
A dehumidifier works by removing excess moisture from the air to reduce humidity levels. It draws in humid air using a fan, then passes it over cold coils. As the air cools, the moisture condenses into water droplets, which are collected in a tank or drained away. The dry air is then reheated slightly and released back into the room, helping maintain a comfortable and healthy indoor environment.
How long will it take to get the moisture under control?
A dehumidifier typically starts to show noticeable results within a few hours, depending on the room size, humidity level, and the unit’s capacity. In very damp spaces, it might take 12 to 24 hours to bring humidity down to a comfortable level. For ongoing effectiveness, it’s best to run the dehumidifier continuously or on a humidity-controlled setting until the desired level is reached.

Bought to use in a
"Bought to use in a spare back bedroom with ensuite ; within hours of setting up unit, the atmosphere was pleasant & the room felt warm . Had to double check unit was on , as so quiet in operation. Great product , barely uses any electric & unobtrusive in the room. very pleased"
Superb piece of kit. Amazed
"Superb piece of kit. Amazed by amount of water it gets from home. Noticed a difference already. Clothes drying a lot quicker now. And it costs 2p an hour to run."
Great Product
"Perfect for a job slightly bigger than a small domestic need , yet small enough not to be obtrusive.Does a grand job."
Works as advertised.
"A good product that performs well."
Great little dehumidifier
"For the money this is a super bit of kit. The addition of WiFi allows use of the Tuya smart home app so a schedule can be set up and you’re able to see what the humidity level is and operate the dehumidifier using your smart phone. I needed to reduce the humidity in my triple garage where I store a couple of classic cars. Running this on economy 7 overnight for a few hours is very cost effective and will prevent long-term damage from rust, mould & mildew. My only (small) gripe is remembering to empty the water container & which can be a bit fiddly. However, I’ll be using the constant drain tube when I find time to connect it, so this won’t be an issue going forward."
Fantastic Dehumidifier
"After using this now for a few weeks I've found it great for helping to dry clothes Not only does this save on electricity compared to a tumble dryer, it has speeded up the clothes drying on a clothes maiden. This dehumidifier has a clothes drying option which allows the dehumidifier to run past its preset value to be able to pull more moisture out of the clothes and surrounding air. I love that I can control this machine via an App and Alexa, I've set the machine to dry and turned it off remotely some hours later The App allows you to see the current moisture within the room as well as the temperature. I'm more than happy with my new purchase and would recommend this to anyone looking to buy one."
It's Great
"Was researching dehumidifiers to dry my clothes. Someone in a forum mentioned this one. So I plucked for it. It's great 20 litres I thought would be too large, but it turns out it's not. Amazing to see the water that gets sucked out of my washing. Can dry my clothes in a day in my conservatory when I'm at work. Auto stops when full. On castors which makes it easy for me to turn around when I want to empty the tank. Very impressed so far."
Very powerful humidifier
"Having the dehumidifier for my double garage, I am super happy with its performance! I wet car is completely dry after less than 8 hours (garage is sealed so, no other way to dry)."
