Many people associate humidity problems with fall and winter, but in fact, the air in your home can become uncomfortably humid even in the summer. High humidity makes rooms feel stuffy, causes windows to fog up, and can promote mold growth over time.
Why does humidity rise in the summer?
In the summer, outdoor air often contains a lot of moisture. If you open windows or if the ventilation system brings moist outdoor air into the room, the relative humidity can quickly rise above the recommended level.
The following also contribute to humidity:
- drying laundry indoors;
- taking a shower;
- food preparation;
- inadequate ventilation;
- basements and cooler rooms.
What is a normal level of humidity at home?
The ideal relative humidity is between 40% and 60%. If the humidity level consistently rises above 60%, the risk of mold, dust mites, and unpleasant odors increases.

How can you tell if there’s too much moisture?
Signs of excessive moisture may include:
- condensation on windows;
- mold stains on the walls;
- a musty smell;
- damp clothes and bedding;
- Stuffy, stuffy indoor air.
If you notice these symptoms, you should measure the humidity in the room using a hygrometer or a humidity meter.
Does ventilation help?
Proper ventilation helps remove excess moisture, but the situation can be more complicated in the summer. If the outside air is humid, ventilation can actually bring more moisture indoors.

When do you need a dehumidifier?
If the humidity level is consistently above 60%, the most effective solution is a dehumidifier.
A dehumidifier helps:
- reduce the risk of mold growth;
- speed up the drying of laundry;
- improve the indoor climate;
- remove excess moisture after water damage;
- reduce condensation on windows.

FAQ
Is high humidity harmful to your health?
Yes. Excess moisture promotes the growth of mold and dust mites, which can cause allergies and respiratory problems.
Does the heat recovery unit remove moisture?
A heat recovery unit helps with air exchange, but it does not replace a dehumidifier in situations where humidity levels are high.
Does the dehumidifier work in the summer, too?
Yes. In fact, dehumidifiers are often used in the summer, when the outdoor air is very humid.
Which dehumidifier is best for an apartment?
In most cases, a dehumidifier with a capacity of 10–25 l/24 h is sufficient, but the choice depends on the size of the room and the humidity level.
How quickly does a dehumidifier reduce humidity?
Depending on the room and the unit’s capacity, the humidity level may drop to the desired range within a few hours to a couple of days.
