American Lung Association Reports 2025 "State Of The Air" Findings

Each year since 2000 the American Lung Association (ALA) has published their “State of the Air” report. Recently the ALA released the 2025 edition filled with information about air quality across the United States. Here’s an overview of what they found.

Air Pollution Is Still A Growing Problem

Despite efforts to curb air pollution sources, environmental circumstances have made air pollution levels worse. Incidents such as wildfires have been made worse due to extreme heat and drought conditions. All of these combined to make particle pollution and ozone levels a problem for larger areas of the United States. Per the ALA unhealthy levels of ozone and particle pollution now affect almost half of the entire United States population (156.1 million people).

 

Particle Pollution Is Still A Problem

The report looks at both short and long term particle pollution levels. Short term particle pollution spikes have been mostly tied to wildfire activity across the country. Due to the nature of wildfire smoke to drift across far distances, more people are being exposed to smoke particles than in previous years. 2024 saw the most ever recorded number of particle pollution days in the “very unhealthy” range. 

 

In regard to year-round particle pollution levels the ALA reports that over 85 million people live in areas with high particle pollution levels. This is actually an improvement over last year’s report which found 90.7 million people were affected. Unsurprisingly the ALA found that particle pollution sources such as highway traffic, burning fossil fuels, oil/gas drilling, and heavy industry were the biggest causes of air pollution.

 

Ozone Pollution Is On The Rise Again

After years of declining levels, unfortunately ozone pollution is on the rise again. The ALA estimates that nearly 125 million people live in areas with unhealthy levels of ozone. Some areas saw large swings in ozone levels to the detriment of health conditions. Wildfires were a large part of the reasons behind these rising ozone levels. High temperatures combined with wildfire generated pollutants to create the perfect ozone forming conditions.

 

What Can We Do?

So how can we stop air pollution? The ALA stresses protecting the U.S. Environmental Protection Agency (EPA) as a major tool in the fight against air pollution. It is through the EPA that the ALA is able to access air pollution monitoring data that keeps the public informed. Recent staffing cuts at the EPA jeopardize the collection of this data. The EPA is also part of preventing pollution at the source through planning, inspections and regulatory guidelines.

Fall Leaf Burning and Air Quality

Fall Leaf Burning and Air Quality

Backyard burning is pretty much exactly what it sounds like. On their own properties, people burn vegetative waste or household trash that would typically be recycled or sent to a landfill. Burning can happen in a barrel, homemade burn box, wood stove, outdoor boiler, or an open pit [1][1].

Some people think of backyard burning as a nostalgic autumn tradition and convenient, affordable way to get rid of leaves and waste. Others don't think about it at all … until the smoke from their neighbor's burn pile shows up in the air around and inside their home.

Smoking Is Making a Comeback. What Does That Mean for Your Air?

Smoking Is Making a Comeback. What Does That Mean for Your Air?

Cigarettes are having a cultural moment again. For a while, they seemed destined to become a relic of another era. Then came vaping, sleek electronic devices, flavored nicotine, a way to smoke almost anywhere, and a whole new aesthetic. 

Now, the pendulum appears to be swinging again.

Recent cultural coverage has pointed renewed interest in something trendsetters are calling analog smoking, especially among younger consumers. Cigarettes are showing up in fashion, celebrity imagery, nightlife culture, and social media feeds, alongside terms like cigfluencers, Gen Z smoking, and even vape fatigue.

Living and Breathing with Lyme Disease

Living and Breathing with Lyme Disease

When you were a kid and had never seen "Lyme disease" spelled out before, you might have assumed it had something to do with little green citrus fruits. (No? Just me?) 

Turns out, the disease is named for Lyme, Connecticut, where the first cluster of cases was documented back in 1977. Unfortunately, Lyme disease has spread far beyond Lyme's town limits: Today, it's been reported in almost every U.S. state, but the Northeast, Mid-Atlantic, and Upper Midwest regions see the most cases. It also exists in Asia, Europe, and other parts of the world [1, 2][1, 2].

What You Should Know About Humidifiers

What You Should Know About Humidifiers

Clean air isn't just about clearing out particles and volatile organic compounds. Humidity is an important component of indoor air quality (IAQ), and the United States Environmental Protection Agency (EPA) lists monitoring and adjusting humidity as a way to improve the air in your home [1][1]. 

Plus, research suggests that indoor humidity could play a bigger role in your health than you might think. Experimental studies show that too much or too little humidity can create conditions that make it easier for germs and allergens to stick around [2][2].

Hurricane Season Starts Outside. The Air Prep Starts at Home.

Hurricane prep usually starts with the obvious: batteries, bottled water, flashlights, medications, and a plan for where to go if conditions turn dangerous. But hurricane season home preparation should also include the air inside your home.

Outside In: How Your Yard Affects Your Indoor Air Quality

Counterintuitively, a big part of maintaining good indoor air quality (IAQ) is being more mindful of the air outside your home. That's because half of what's in the air outside can make its way inside [1][1].

From pollen and mold spores to pesticides and other lawn treatments, lots of different outdoor contaminants find their way into the air you breathe when you're chilling on the couch, eating lunch at the kitchen table, or even tucked under the covers in bed.
