How to Use a Bathroom Vent to Blow in Clean Air

As the weather gets colder, you shut your windows and doors to keep in the heat. Although this helps you save money on your heating bill, it can create a stuffy home. The smells from cooking, pets and dirty laundry all combine to make your home smell and feel stale. One way to freshen your home is to open your windows and let in air from the outside. Using your bathroom exhaust fan helps to speed up the circulation of fresh air. As the outside air is pulled in, the exhaust fan moves it out.

Instructions

- 1
  Use an outdoor thermometer to check the outside temperature. Turn the thermostats in your home down a few degrees below the outside temperature. This keeps your heat from turning on and wasting energy as you air out your home.

  Open a window in each room that is on the same floor as the bathroom. Open the bathroom window, as well as any storm windows. All the windows should be up at least 2 inches. For maximum airflow, open them all the way.

  Turn on the bathroom exhaust fan. Let it pull in air for at least 20 minutes. Depending on how strong your exhaust fan is, you should feel some air flowing in from the windows.

  Turn the exhaust fan off once your home's air smells and feels freshened. Shut all windows and storm windows before you turn your thermostats back to their normal settings.
