The 4th of July is one of the most beloved American holidays. Families gather for cookouts, fireworks light up the night sky, and neighborhoods come alive with celebration. But while we’re enjoying the show, there’s something invisible lingering in the air — fireworks-related air pollution.
Yes, fireworks can significantly impact air quality. For individuals with asthma, allergies, or respiratory conditions, the effects can last long after the final spark fades. The good news? There are simple, no-cost ways to protect your indoor air — including free air purifiers and energy-saving upgrades through NYS Energy Audits.
NYS Energy Audits has been helping NYC families stay comfortable, safe and save on energy bills for over 15 years. Qualifying households can receive FREE upgrades like free air purifiers, air sealing, thermostats and more. See if you qualify HERE.
The Hidden Side of Fireworks: What’s Really in the Smoke?
Fireworks contain a mix of metallic compounds, sulfur, charcoal, and oxidizers. When ignited, they release more than just beautiful colors — they also emit:
- PM2.5 (Fine Particulate Matter): Tiny particles that can travel deep into your lungs and bloodstream.
- Heavy Metals: Including barium (green), strontium (red), and copper (blue), which give fireworks their colors but can irritate lungs and affect health.
- Carbon dioxide and other gases: Contributing to greenhouse emissions and overall poor air quality.
According to the Environmental Protection Agency (EPA), air pollution levels spike on and immediately after July 4th, with PM2.5 levels rising up to 42% higher than normal in some areas. These particles can linger in the air for hours — or even days — depending on the weather.
Who’s Most at Risk?
While everyone is exposed to air pollution, certain groups are more vulnerable:
- Children and older adults
- Individuals with asthma, COPD, or seasonal allergies
- People with heart or respiratory conditions
- Those living in cities or close to fireworks shows
Even if you’re generally healthy, you might notice post-firework symptoms like:
- Trouble breathing, especially at night
- Coughing or wheezing
- Sinus pressure or congestion
- Eye or throat irritation
How to Protect Your Home’s Air Quality After Fireworks
You can’t stop the neighborhood fireworks, but you can protect your home’s air. Here are three smart steps:
1. Keep Windows Closed
Keep all windows and doors closed for at least 24–48 hours after fireworks. This prevents polluted outdoor air from circulating inside your home.
2. Use an Air Purifier
High-quality HEPA air purifiers help trap fine particles, smoke residue, and allergens. They’re especially helpful after holidays like the 4th of July or during peak allergy season.
