Dehumidifier page
How big a dehumidifier do you need?

It depends on the size of the room and how much moisture is in the air. Larger spaces such as basements and garages require dehumidifiers with higher capacity; smaller dehumidifiers cannot remove the large amount of moisture in the air and do not reach the whole space.

Can a dehumidifier be left running all the time?

Yes. Many dehumidifiers are designed for continuous operation and start automatically when the humidity becomes too high.

How can you prevent moisture problems in your house?

Good ventilation and a stable temperature are important, but in many cases this is not enough. A dehumidifier can help to keep the humidity at a level where moisture damage does not occur.

When does mould start to grow in a house?

Mould can start to grow when the humidity is above 70% for a long period of time. It is therefore important to keep the humidity at a stable level, around 40-60%.

What is normal humidity in a house?

Normal and healthy indoor humidity is between 40–60%. If the humidity is higher for long periods, there is an increased risk of mould, odours and moisture damage.

How do you know if you have a damp problem in your house?

Common signs of damp problems include condensation on windows, musty odours, mould stains on walls or ceilings, and laundry or clothes drying slowly. A dehumidifier can help reduce humidity and create a drier indoor climate.

How can you prevent black mould in your home?

The most important thing is to keep the humidity at a stable level, around 40-60%. In spaces such as basements, bathrooms and laundry rooms, a dehumidifier can help keep the climate drier and reduce the risk of mould.

How do you get rid of black mould?

If black mould has appeared, it must first be cleaned or removed, depending on the extent of the problem. To prevent the mould from returning, it is also important to reduce the humidity in the room; a dehumidifier is a good tool to use for this.

Is black mould dangerous?

Black mould can affect the indoor environment and, in some cases, cause respiratory irritation or allergy-like symptoms. It is therefore important to address both the mould and the cause of the moisture.

What is black mould and why does it occur?

Black mould is a type of mould that thrives in damp environments where the humidity is high for long periods of time. It often occurs in basements, bathrooms, laundry rooms or other areas where ventilation is limited and moisture cannot escape.
