Window condensation is a common problem, especially in the colder months

By Vitia

Window condensation is a common problem, especially in the colder months. Drops of water on the glass do not look good and can lead to mold and damage to frames and window sills in the long term. In addition to regular ventilation and proper heating, properly selected houseplants can also help you significantly.
Below you will find a practical and natural way to reduce humidity in the room – without chemicals and complicated solutions.

Why does condensation form on windows

Condensation occurs when warm and humid air in the room comes into contact with the cold surface of the glass. The most common causes are:

high humidity in the apartment (cooking, showering, drying laundry),
insufficient ventilation,
a large difference between indoor and outdoor temperatures.
This is where some houseplants come into play, which naturally regulate air humidity.
