Air Quality: Solution 2 – Avoid Poor Air Quality


Big Idea: It is important to avoid poor air quality days by staying indoors and closing doors and windows.

Talking Points:

  • On these days, put the air conditioner on “re-circulate” mode in the home and when commuting to work or school in a car.
  • Research shows that HEPA filters in HVAC systems and portable room cleaners are effective in removing small particles from the air. Get the appropriate sized HVAC filter, and change filters regularly to ensure they are effective.
  • If you or someone in your home has asthma, consider maintaining a “clean room” where the person with asthma can spend most of their time on high pollution days. In this space, regularly clean surfaces, use a HEPA vacuum, and keep pets, tobacco smoke, and other asthma triggers out.
  • Finally, remember that people with asthma should have their medications readily available at all times.
