Why is Ventilation Important?
Proper ventilation is crucial, especially during the winter months. If you have new, airtight windows, you should ventilate the rooms several times a day. The best way to ventilate is to open all the windows briefly to create a draft, allowing the humid air to leave the room.

Leaving a window slightly open for a long time or using the “tilt” position is not effective. Always ventilate when the humidity level in the room exceeds 60%.
How to Use a Humidity Meter Properly and What is its Cost?
The easiest way to determine if there is a risk of mold is by monitoring the humidity levels in your home. Digital humidity meters, which often double as thermometers, can be found in well-stocked electronics stores for about 10 USD. This modest investment allows you to always check if the air humidity is too high. Ideally, the humidity should be below 60%. Levels above 65% indicate a high risk of mold growth in critical areas.
How to Arrange Furniture to Prevent Mold?
Avoid placing large pieces of furniture, like wardrobes, against walls prone to moisture. This obstructs air circulation, creating cooler zones that are ideal for mold growth. Once mold appears, it can damage both the wall and the furniture.
If possible, keep beds slightly away from cold exterior walls to ensure air circulation. The worst scenario is a bed pushed against an exterior wall with the entire edge blocked by pillows, which can lead to mold growth behind the bed.
Are Anti-Mold Coatings Effective?
There are many anti-mold coatings available, either as a primer or as additives for paint. These can be quite effective in preventing mold. However, because these are chemical solutions, they should be used only in areas where there is a direct risk of mold.
Is a Dehumidifier a Good Idea?
Dehumidifiers are plastic containers with calcium chloride that efficiently absorb moisture, especially in higher, more dangerous concentrations that can affect the health of household members. Dehumidifiers are completely safe and harmless to health and are very effective in preventing mold. Their use is recommended during the most critical months, usually the heating season.
Check Window Seals
First, ensure that your windows do not leak during rain. Check the drainage channels at the bottom of the frames to make sure they are not clogged, as this can hinder water drainage. Inspect the condition of seals and silicone gaskets, as these are inexpensive repairs that can be done with minimal investment.
Key Tips to Prevent Mold Recurrence:
- Ventilate as Needed: Regular and proper ventilation is crucial.
- Monitor Air Humidity: Use a humidity meter to keep levels below 60%.
- Reduce Major Sources of Moisture: Ensure bathrooms are well-ventilated post-shower, and use kitchen exhaust fans during cooking.
- Ensure Air Circulation: Keep large furniture pieces away from walls prone to moisture.
- Use Dehumidifiers: Especially during the heating season to keep moisture levels in check.
- Use Anti-Mold Coatings: Apply them in high-risk areas to prevent mold growth.
- Check and Maintain Window Seals: Ensure windows are well-sealed to prevent moisture ingress.
By following these tips, you can effectively prevent the recurrence of mold on your walls, ensuring a healthier and aesthetically pleasing home environment.
