after fires destroyed multiple neighborhoods across Los Angeles County, residents were greeted with clear, blue skies this week. The Air Quality Index (AQI), which measures the concentration of pollutants in the air,suggested that the air was clean and healthy. However, many Angelenos remain skeptical, as their physical reactions tell a different story.
A Frogtown resident, miles away from the fires, reports that her asthma continues to flare up despite wearing a mask and using an air purifier. Similarly, a Los Feliz resident shared with Yahoo Life that the AQI readings in his area have been better than before the fires, which he finds “hard to believe.” He added, “Despite the good to moderate readings, I’m still feeling a burn in my nostrils and dryness in my throat.” This raises the question: is the AQI truly a reliable measure of air quality?
### What is the Air Quality Index?
The Air Quality Index is a tool developed by the Environmental protection Agency (EPA) to communicate outdoor air quality. It operates on a scale from 0 to 500, with higher numbers indicating greater health risks. An AQI value of 50 or below is considered good, while values above 300 are deemed hazardous.
| AQI Range | Air Quality Level | Health implications |
|———–|——————-|———————|
| 0 – 50 | Good | Minimal risk |
| 51 – 100 | Moderate | Acceptable, but may pose risks to sensitive groups |
| 101 - 150 | Unhealthy for Sensitive Groups | Increased health effects for sensitive individuals |
| 151 – 200 | Unhealthy | Health effects for everyone |
| 201 – 300 | Very Unhealthy | Serious health effects |
| 301+ | Hazardous | Emergency conditions |
While the AQI provides a general overview, it may not capture localized or specific health impacts. Experts caution that relying solely on the AQI can be misleading,especially in areas affected by wildfires or other localized pollution sources. For a more extensive understanding, residents are encouraged to monitor their symptoms and consider additional air quality resources.

The AQI is divided into six categories, each represented by a specific color and corresponding health implications:
| AQI Range | Category | Health Impact |
|—————|———————–|———————————————————————————–|
| 0–50 | Good | Air quality is satisfactory, posing little to no risk. |
| 51–100 | Moderate | Air quality is acceptable, but may pose risks for unusually sensitive individuals.|
| 101–150 | Unhealthy for Sensitive Groups | Children, the elderly, and those with respiratory conditions may be affected. |
| 151–200 | Unhealthy | Everyone may begin to experience health effects. |
| 201–300 | Very Unhealthy | Health warnings of emergency conditions; the entire population is likely affected.|
| 301+ | Hazardous | Health alert: everyone may experience serious health effects. |
Who Is Most at Risk?
When the AQI exceeds 100,the air is considered unhealthy,particularly for sensitive groups such as children,the elderly,and individuals with respiratory conditions. As the AQI rises, the risks extend to the general population. For example, an AQI of 150 or higher can lead to respiratory issues, eye irritation, and other health concerns for everyone.
Visualizing the AQI
the CDC’s Air Quality Index chart provides a clear visual depiction of these categories, using six distinct colors to indicate the level of risk. This tool is invaluable for understanding current air quality conditions and taking appropriate precautions.

Understanding Air Quality Index (AQI): What It Tells Us and What It Doesn’t
The air Quality Index (AQI) is a widely used tool to measure air pollution levels and their potential health impacts. however, while it provides valuable insights, it doesn’t tell the full story of air quality.Experts explain what AQI measures, its limitations, and why it’s essential to look beyond this metric for a comprehensive understanding of air pollution.
What Does AQI Measure?
The AQI is based on measurements of criteria air pollutants (CAPs), such as PM2.5 and ozone, according to dr. Chen, a professor in the Department of Environmental and Occupational Health at the University of Nevada, Las Vegas School of Public Health.
- PM2.5: These are fine particulate matter particles measuring 2.5 micrometers or smaller in diameter. Due to their tiny size, thay can penetrate deep into the lungs and even enter the bloodstream, posing notable health risks.
- Ozone: This gas forms when pollutants react in sunlight. It can irritate the lungs, inflame airways, and worsen conditions like asthma, emphysema, and chronic bronchitis.
While a high AQI indicates unsafe air quality, Dr. Chen notes that “a low AQI does not guarantee healthy air quality.” This is as AQI focuses on specific pollutants and may not account for other harmful substances in the air.
How Reliable Are AQI Readings?
The reliability of AQI readings depends on the accuracy of the air monitors used. Amy macpherson, a spokesperson for the California Air Resources Board (CARB), explains that while some AQI readings are based on low-cost sensor data, others rely on regulatory-grade air monitors.
“The regulatory-grade air monitors used to calculate AQI are extensively calibrated and maintained to rigorous standards,” MacPherson says. “CARB is confident that these AQI readings are accurate.”
However, the use of low-cost sensors in some areas may result in less precise measurements, highlighting the importance of understanding the source of AQI data.
What Doesn’t AQI Tell Us?
While AQI is a useful tool, it has limitations. Dr. Chen points out that AQI does not include hazardous air pollutants (HAPs), which are chemicals that may be present in lower concentrations but are more toxic in nature. The Environmental Protection Agency (EPA) has a separate monitoring program for HAPs,as they require specialized measurement techniques.Additionally, AQI cannot account for exposure to air pollutants through ingestion. Such as, when pollutants settle on water or food, they can enter the body through consumption. “Specific toxic air measurements are usually conducted on demand when there is a concern,” Dr.Chen explains.
Key Takeaways
| Aspect | Details |
|————————–|—————————————————————————–|
| What AQI Measures | PM2.5, ozone, and other criteria air pollutants (CAPs). |
| Limitations | Excludes hazardous air pollutants (HAPs) and ingestion-based exposure. |
| Reliability | Depends on the type of air monitors used; regulatory-grade monitors are most accurate. |
Why Look Beyond AQI?
Understanding air quality requires more than just checking the AQI.While it provides a snapshot of pollution levels, it doesn’t capture the full spectrum of risks, especially from toxic chemicals or indirect exposure pathways. For a more comprehensive assessment, experts recommend considering additional data sources, such as EPA’s HAPs monitoring program and localized air quality studies.
By staying informed and aware of these nuances, individuals can better protect their health and make informed decisions about outdoor activities, especially in areas prone to air pollution.
Call to Action: Check your local AQI regularly, but also explore additional air quality resources to get a complete picture of your environment. Stay informed, stay safe!
How to Accurately Assess Air quality at Home: Beyond the AQI
When it comes to monitoring air quality, the Air Quality Index (AQI) has long been a go-to resource for many. However, experts are now highlighting its limitations, especially when it comes to localized pollution. Shahir Masri,an assistant specialist in air pollution exposure assessment and epidemiology at the UC Irvine Program in Public Health,explains that the AQI often fails to capture hyper-localized air quality issues.
“The AQI can’t tell us about very localized air pollution,” Masri tells Yahoo Life.“Is there a small factory near your house? That may cause elevated exposures in your neighborhood, for instance, which cannot be captured by the regional EPA monitor.”
This limitation becomes particularly evident during events like wildfires, where smoke plumes can shift unpredictably. “During a major, short-lived wildfire, individual residents may experience higher PM2.5 exposures than what is reflected by the AQI,” Masri explains.
The Bigger Picture: Regional Air Quality Maps
For a more comprehensive view, Masri recommends using the AQI regional map, which provides a broader viewpoint on air quality across neighboring areas. This tool can help residents understand how localized pollution might differ from regional averages.
Meanwhile, agencies like the California Air Resources Board (CARB) are working to address these gaps. CARB collaborates with the South Coast Air Quality Management District, which operates air toxics monitors in the Los Angeles area. However, as MacPherson notes, “The methodology for collecting, analyzing, and reporting air toxics data is complicated and time-intensive, meaning it takes days or weeks to report air toxics data as compared to minutes or hours for particulate matter data.”
Low-Cost Sensors: A Game-Changer for Home Monitoring
While the AQI remains a valuable resource, technological advancements are offering new ways for individuals to monitor air quality at home. “Recent technological innovation has led to the development and deployment of thousands of low-cost air pollution sensors,” Masri says. These devices are affordable, mobile, and easy to maintain, making them an excellent option for those concerned about their air quality.
One standout example is PurpleAir, a company that began deploying low-cost air quality sensors in 2017. These sensors now provide real-time PM2.5 data across the U.S. and internationally. Available for purchase on the company’s website for around $209, PurpleAir devices have been validated for their accuracy in monitoring PM2.5 levels.
Similarly, Atmotube offers small, mobile sensors at a comparable price point of approximately $179. Both devices are praised for their precision and ease of use, empowering individuals to take control of their air quality monitoring.
| Device | Price | Key Feature |
|——————-|———–|————————————-|

| Atmotube Sensor | $179 | Compact, mobile design |
Why Localized Monitoring Matters
Localized air quality monitoring is crucial, especially in areas with nearby industrial facilities or during environmental crises like wildfires. Traditional AQI measurements, which average data over 24-hour windows, may not reflect short-term spikes in pollution. This is where personal air quality sensors shine, offering real-time data that can help individuals make informed decisions about their health and safety.
For outdoor air quality, Chen recommends relying on EPA air monitoring stations, which measure criteria air pollutants and sometimes include more specific measurements. However, for those seeking immediate, localized insights, low-cost sensors like those from PurpleAir and Atmotube are becoming indispensable tools.
Take Control of Your Air Quality
