What should be the temperature at home to prevent mold: the optimal indicator

Low temperatures and high humidity can lead to indoor mold growth. But what temperature is considered low, and what should the humidity level be to prevent the appearance of these harmful microorganisms on walls and surfaces?

In reality, there is no single correct answer as it depends on the season. OBOZREVATEL consulted with experts to determine the ideal conditions for summer and winter.

Summer and Winter Conditions

In the summer, the recommended indoor temperature is typically higher, usually around 20-22 degrees Celsius, although it can vary slightly. During the heating season, temperatures are maintained at around 18-20 degrees Celsius. Mold spores thrive within a temperature range of 5 to 38 degrees Celsius.

The Key Factor

The primary factor for mold development is not only temperature but also humidity. Mold spores, which are always present in the air, settle on surfaces and begin to germinate when humidity levels are conducive.

Humidity levels can increase due to water vapor, which is abundant in places like bathrooms and kitchens, as well as condensation, which occurs when temperature fluctuations lead to the collection of moisture on surfaces. For instance, windows may accumulate condensation in the winter due to temperature disparities between the interior and exterior.

How to Control Humidity Levels

One of the simplest ways to reduce excess humidity in the air is through proper ventilation. Opening windows for a few minutes at least once a day can help. In rooms without windows, it is advisable to install an exhaust hood to expel steam into the ventilation system. In more challenging cases, a dehumidifier or DIY humidity absorbers, such as containers filled with baking soda or salt, can be effective.
