Reduce humidity in living spaces

To avoid mold:
Excessively humid air promotes mold growth. Mold spores trigger allergies, asthma, and respiratory problems, which are especially dangerous for children and allergy sufferers.

To reduce dust mites:
Mites love moisture and warmth. Humidity levels below 60% make them uncomfortable, significantly reducing allergy triggers.

To protect the respiratory tract:
Dry air irritates the respiratory tract and mucous membranes, but excessively humid air can cause respiratory problems. Optimal humidity keeps mucous membranes healthy and thus strengthens your immune system.

Sleep better:
A balanced indoor climate promotes deeper sleep. You wake up more rested and feel fitter during the day. Humidity in the bedroom is especially important because you spend a lot of time there. Too much humidity promotes mold and dust mites, while too dry air irritates the mucous membranes and disrupts sleep. A balance of 40–60% ensures healthy sleep and greater well-being.

Comfortable living experience:
Too humid air can quickly make you feel tired and uncomfortable, while dry air can irritate your skin and eyes. The right humidity makes your stay pleasant.

Maintaining the value of your apartment:
Furniture, floors, and walls suffer from persistently high humidity. The right indoor climate protects your home from structural damage and maintains a high quality of life in the long term. Humidity in living spaces is crucial for your well-being, your health, and the value retention of your home.

In many households, moisture is a daily occurrence. Cooking, showering, drying laundry, and even our breathing release several liters of water into the air every day. This moisture builds up particularly in densely insulated or poorly ventilated homes.

Structural defects such as leaky roofs or rising damp can also contribute to persistent wetness.

Even aquariums, houseplants and wet laundry in the room increase the humidity considerably.

In short: Where a lot of moisture is produced and little can escape, the indoor climate starts to "sweat." That's why optimal indoor humidity is important.

Constantly humid air is not only annoying but also unhealthy.

High humidity provides ideal conditions for germs, mold spores and dust mites to reproduce.

Mold grows particularly well at relative humidity levels of around 70–80% and can begin to thrive above ~60%.

House dust mites love a warm, humid environment with humidity levels of 60% and above; they feel very comfortable at humidity levels of over 70%.

Their excretions cause allergies with symptoms ranging from a persistent runny nose to breathing difficulties.

Curiously, even “bone-dry” air is not optimal: Below ~40% relative humidity, dust pollution increases, which can also irritate the respiratory tract.

The motto is: find a healthy balance.

Damp walls lead to wavy wallpaper and peeling paint. Condensation in corners and on cold exterior walls can encourage mold and mildew.

Wood swells, and furniture and floors can become stained or even rotten due to moisture.

It's no wonder, then, that too much moisture in your home can be very expensive in the long run, not to mention a loss of comfort.

Misted windows and damp walls are clear warning signs: Relative humidity above ~60% promotes mold growth and can, in the long run, be harmful to both your health and your home furnishings.

What humidity is the right one?

Experts recommend a relative humidity of approximately 40% to 60% in living spaces. This range is considered comfortable by most people. Values ​​around 50% RH are considered the ideal compromise between too dry and too humid. In this range, mucous membranes remain moist enough, while mold and mites are significantly inhibited.

The Federal Environment Agency advises not to exceed 60% permanently.

However, the optimal humidity also depends on the room. In living rooms, offices, and bedrooms, 40–60% is ideal, with a room temperature of approximately 18–22°C. In the bathroom or after showering, humidity may be higher for a short time (50–70%), but should be reduced again by ventilating.

Room temperature is also important: Cold air can retain less moisture. If the room temperature drops below ~16 °C, the risk of mold growth increases dramatically, even at the same humidity level – moisture then condenses on cold walls.

Conclusion: Keep living spaces moderately warm and the relative humidity in the optimal range mentioned.

An electric dehumidifier regulates the
Humidity is active and is weather independent.

A dehumidifier works even in rain or in enclosed spaces without windows. Especially in rooms that are difficult to ventilate (basements, storage rooms, and indoor bathrooms), a dehumidifier is often the only option.

Dehumidifiers also optimise the indoor climate for allergy sufferers : Less humidity means
fewer mites and mold spores in the air.

Many appliances have a laundry drying mode ,
which speeds up the drying of clothes indoors – useful when
It's bad weather outside.

And the best thing : Modern dehumidifiers work
energy efficient and quiet enough to run in the background without
that they are disturbing.

• Pay attention to increased humidity
• Pay attention to maximum humidity
• Pay attention to low humidity

Therefore, my recommendation: Regularly measure the humidity for a pleasant and healthy indoor climate.
