# Air out

> <p><span>The air inside your home can be more polluted than the air outside, so it's important to let fresh air in often. We recommend opening windows or doors for 2 periods of 5 minutes each day to get some fresh air flowing. You could try doing this in the morning and before bedtime while you brush your teeth.</span></p>
