Humidity at home? Clever grannies' trick to solve this problem for good

4- Ventilate to let moisture out
A low-cost option, ventilating your home is essential! Remember to open your windows to allow humid air to escape from the house. Open all the windows in the different rooms of the house to help air circulation. However, keep your windows closed on rainy days, simply because humid air increases the humidity in your home.

5- Dehumidifiers and air conditioners to reduce humidity
Dehumidifiers and air conditioners can be useful in hot and humid environments to reduce the amount of moisture in the air. However, care must be taken to ensure that these devices do not turn into biological contaminants later on.
