Air Quality

Healthy air is a vital component of healthy communities. Everyone deserves to breathe safe, healthy air. Unhealthy air that contains pollutants like particulate matter (or particle pollution), ozone, nitrogen dioxide and sulfur dioxide can lead to the following health issues for children:

  • Asthma attacks
  • Decreased lung function/slowed lung function growth
  • Development of asthma
  • Increased hospital admissions and ED visits for asthma
  • Increased severity of asthma attacks
  • Lung disease

Environmental Protection Agency (EPA) Grant for Community Air Monitoring

In 2023, the Environmental Protection Agency (EPA) awarded us $500,000 for a 3-year project that aims to create a community-based network of neighborhood-level air quality monitoring stations in Milwaukee, Wisconsin, focusing on neighborhoods with high asthma burdens. We are excited to launch the Love My Air program in Milwaukee in fall 2023! Through this program, we will install air quality sensors at select schools in the Milwaukee Public Schools district. We will engage schools in air quality monitoring activities through involvement in air quality campaigns (like anti-idling), student engagement and leadership, school STEAM curriculum/community science monitoring using sensors, and education and awareness programs for students, families and the community. The community will also receive education about how to access the neighborhood-level air quality data from those sensors, what the data means, and the action steps tied to that data so that residents have both the tools and knowledge necessary to respond to asthma-related air quality risk factors.


The Love My Air program relies on partnerships with state and local entities to accomplish its goals.

Visit What Makes Outdoor Air Unhealthy | American Lung Association for more info about each of these pollutants.

  • Children and teens whose lungs are still developing
  • Older adults
  • People who live and work near busy highways or factories; due to systemic racism and environmental injustice, this tends to be people of color and/or people with lower incomes
  • People with cardiovascular disease or diabetes
  • People with lung diseases like asthma
  • Check the daily air pollution forecast | Check now
  • If you drive to school, turn off your engine while dropping off or picking up students – idling vehicles give off higher levels of harmful air pollution
  • Walk, bike or carpool to school
  • When pollution levels are high, take steps to protect your health:
    • Avoid exercising/playing outdoors
    • Avoid opening windows
    • Keep your quick-relief asthma medication on hand if you are active outdoors

The Air Quality Index, or AQI, is used to warn the public when air pollution is dangerous and can be found at (View AQI table)
