The Good News

You now understand why air quality matters. So what can you do about it?

The good news: there are actions at every level—personal, household, school, and community—that can make a real difference!

Level 1: Personal Actions

Action How It Helps Difficulty
Check AQI before outdoor activities Avoid high exposure times Easy
Reduce outdoor exertion on bad air days Less air inhaled = less exposure Easy
Use N95/KN95 mask on smoky days Filters out PM2.5 Easy
Walk/bike/transit instead of driving Reduces your contribution to pollution Medium
Share air quality info with others Helps more people protect themselves Easy

Level 2: Household Actions

Action How It Helps Cost
Use range hood when cooking Removes cooking particles at source Free (if you have one)
Upgrade HVAC filter to MERV-13+ Filters air circulating through home $15-30/filter
Use portable HEPA air purifier Cleans air in a specific room $100-300
Build a Corsi-Rosenthal box DIY air cleaner, very effective $50-80
Avoid candles, incense, smoking indoors Eliminates major indoor PM sources Free

Unit 5 Summary

Health Burden

Air pollution is a top global health risk, causing 7 million deaths/year. The AQI helps us understand daily risk.

Respiratory Effects

Asthma and allergies are triggered and worsened by air pollution. 25 million Americans have asthma.

Systemic Effects

Air pollution affects heart, brain, and other organs. More deaths from heart disease than lung disease.

Environmental Justice

Pollution exposure is unequal. Low-income communities and communities of color face higher burdens.

Key Takeaway

Knowledge is power. Now that you understand how air quality affects health, you can take action at every level—from personal choices to community advocacy. Clean air is not just an environmental issue; it's a health issue and a justice issue. Every action you take to improve air quality helps protect yourself, your family, and your community.
