QUESTION: Mold and mildew: how to improve ventilation and humidity?

Improving ventilation and normalizing humidity levels in an apartment play a key role in creating a healthy microclimate and preventing dampness. For this task, the golden 80/20 rule works great in rooms: first solve the two or three main problems responsible for air exchange and excess moisture removal, and only then improve small interior details.

First of all, check the operability of natural ventilation in the apartment. Bring a sheet of paper to the ventilation grill in the kitchen or bathroom; if it is held by the air flow, it means the exhaust duct is functioning normally. If there is no draft, you must call specialists to clean the general building ventilation shafts.

Install forced exhaust fans in bathrooms and kitchens, connecting them to the main light switch or providing a delayed shut-off timer. This simple technical solution allows you to quickly remove excess moisture immediately after water procedures or cooking, preventing steam from settling as condensation on cold walls.

In living rooms, regularly ventilate cross-wise for five to ten minutes daily, regardless of weather conditions outside the window. This method is more effective than slow micro-ventilation through a slightly ajar sash, as it completely updates the volume of air in the room without having time to strongly cool massive walls and furniture.

If necessary, purchase a stationary electric dehumidifier for particularly damp rooms or basements. This device effectively collects excess moisture from the air into a special reservoir, maintaining the specified humidity parameters. The combination of these measures will save your home from stuffiness, condensation, and dampness forever.
