How To Keep Lungs Healthy
Reduce indoor air pollution
Indoor air pollution can damage the lungs and worsen asthma and allergies. To reduce indoor air pollution, a person can follow these measures:
- Use an Environmental Protection Agency-approved air filter, and replace it every 60–90 days.
- Test the home for mold if there is visible mold or a moldy smell.
- Test the home for radon.
- Avoid using chemicals with a strong odor in an unventilated space.
- Wear a mask when painting or working with strong chemicals.
- Do not allow people to smoke inside the home.
- Keep doors and windows closed when the air outside is very polluted.
