Dehumidifier FAQ
What is a dehumidifier and how does it work?
A dehumidifier draws excess moisture from the air, keeping humidity levels at an acceptable level. Too much moisture in the air can lead to damp, mould, and affect those with allergies. You’ll find it harder to dry your clothes, your walls will become damp and damaged, and some family members may suffer from respiratory problems.
A refrigerant dehumidifier works by drawing air through a filter and over cold coils. The water condenses onto the cold coils and drops into the water tank. Once the tank is full, it needs to be emptied.
Desiccant dehumidifiers use an absorbent material to extract water. The material is heated so the moisture drips into the water tank.
How much water should a dehumidifier collect in a day?
The amount of water your dehumidifier collects will depend on the power, size and type of dehumidifier you choose. Powerful dehumidifiers with large water tanks collect up to 8L of water per day. Mini dehumidifiers designed for small spaces like cars may collect just 500ml.
How much does it cost to run a dehumidifier?
The cost of running a dehumidifier depends on the size, temperature of the room, and any energy saving features. Those with a low power rating (less than 250W) cost around 50p a day. More powerful dehumidifiers can cost up to £1.50.
What are the benefits of a dehumidifier?
Clearing damp air from your home has a range of benefits. Dehumidifiers can help reduce unpleasant smells, keep the air fresh and prevent damp or mould from forming on the walls. If you struggle to dry your clothes in the winter, it could be because your home is too damp, and a dehumidifier can help with this.
Breathing in overly damp air can cause respiratory issues and cause those with asthma to suffer. Dehumidifiers will also reduce the build up of dust and mites, keeping your lungs, furniture and appliances in good condition!
How much electricity does a dehumidifier use?
This again depends on the type of dehumidifier you purchase, as some use no electricity whatsoever! Small dehumidifiers have under 100W of power, while large models designed for big homes may have up to 750W.
How long should you leave a dehumidifier on for?
Many dehumidifiers come with either a timer or auto shut off, meaning once the water tank is full the unit will switch off. Leaving your dehumidifier on for too long won’t do any harm, but it will rack up a large energy bill!
To start with, leave your humidifier on for a few hours at a time so you can clear as much damp air as possible. Once the room has reached the desired humidity (ideally this should be under 50%), you can reduce the time your dehumidifier is switched on for.
