You Cook

Cooking creates gases like carbon monoxide, formaldehyde, etc., which mix up with the atmosphere to pollute your house. Whatever you use to cook- gas, wood or electric stove, everything will contaminate the air given that they are a source of heat. Adding on to that, heating oil and fat at high temperature also releases pollutants.


Air from the Outside

After all, you cannot close your windows and door all the time. You sometimes need to welcome the outdoor air, but the problem is that pollutants also sneak their way in. Later on, they get trapped inside your house. However, you can manage this by talking with your home renovator contractor and installing well-placed ventilation.
