Why is Proper Ventilation Important for a House?

Proper ventilation helps keep the air inside the house fresh and clean.
It helps remove bad smells and moisture from the air.
Good ventilation can prevent the growth of mold and mildew, which can be harmful to our health.

Example 1: If you bake cookies in the kitchen, opening a window or turning on a fan helps let out the yummy smell so the air doesn't feel stuffy.

Example 2: When we take a hot shower, the bathroom can get steamy. A fan can help remove the steam and keep the air dry, preventing mold from growing.

Example 3: In winter, when we use heaters, the air can become dry. Opening a window for a little while lets fresh air in, making it easier to breathe.

Fun Fact: Fresh air is just like water for our bodies! It helps us stay healthy and feel good!
