Indoor air quality is when we talk about the air that we breathe inside buildings, like houses or schools. Just like we need good food to keep our bodies healthy, we need clean air to keep our bodies healthy too.
The air inside buildings can have lots of tiny things in it that we can't see, like mold, dust, chemicals, and even germs. These things can make us sick, especially if we breathe them in a lot.
So, people who build or take care of buildings need to make sure that the air inside is clean and healthy for us to breathe. They can do this by using special air filters, cleaning and fixing things that might be causing problems, or even adding plants to help clean the air!
It's super important to have good indoor air quality because the air we breathe can affect our health and how we feel. So, always remember to take deep breaths of fresh, clean air!
