Hey everyone, we've got an air quality alert happening in Ely, Minnesota, so let's dive into what's going on. This article will break down the details of the alert, what PM2.5 is, and what you can do to stay safe.

Understanding the Air Quality Alert in Ely

As of July 20, 2025, at 02:53 CDT, the air quality in Ely, Minnesota, has triggered an alert. The 1-hour Air Quality Index (AQI) reading has hit 163 for PM2.5, which means the air quality is unhealthy. Two monitors are reporting AQI values above 90, raising concerns for sensitive groups and the general population. Let's break down what this means for you and what actions you might want to consider.

What is AQI and Why Does It Matter?

The Air Quality Index (AQI) is a scale used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. It focuses on health effects you may experience within a few hours or days after breathing polluted air. The EPA calculates the AQI for five major air pollutants regulated by the Clean Air Act: ground-level ozone, particle pollution (also known as particulate matter), carbon monoxide, sulfur dioxide, and nitrogen dioxide.

The AQI ranges from 0 to 500, with different levels indicating varying degrees of air pollution and associated health risks. Here’s a quick breakdown:

  • 0-50: Good – Air quality is satisfactory, and air pollution poses little or no risk.
  • 51-100: Moderate – Air quality is acceptable; however, for some pollutants, there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
  • 101-150: Unhealthy for Sensitive Groups – Members of sensitive groups may experience health effects. The general public is less likely to be affected.
  • 151-200: Unhealthy – Everyone may begin to experience health effects; members of sensitive groups may experience more serious effects.
  • 201-300: Very Unhealthy – Health alert: everyone may experience more serious health effects.
  • 301-500: Hazardous – Health warnings of emergency conditions. The entire population is more likely to be affected.

In Ely's case, an AQI of 163 falls into the Unhealthy category, meaning everyone may begin to experience health effects, and sensitive groups may experience more serious issues. It’s crucial to understand what this means and take necessary precautions.

What is PM2.5?

PM2.5 refers to fine particulate matter that has a diameter of 2.5 micrometers or less. To give you an idea of how tiny that is, it’s about 30 times smaller than the average human hair! These microscopic particles can come from a variety of sources, including:

  • Combustion sources: Power plants, industrial processes, vehicle exhaust, and wood burning.
  • Natural sources: Wildfires and dust storms.
  • Secondary formation: Chemical reactions in the atmosphere involving pollutants like sulfur dioxide and nitrogen oxides.

Because PM2.5 particles are so small, they can travel deep into the respiratory tract, reaching the lungs and even entering the bloodstream. This can lead to a range of health problems, particularly for those with existing respiratory or cardiovascular conditions. Exposure to high levels of PM2.5 can trigger asthma attacks, worsen heart conditions, and increase the risk of respiratory infections. It's especially harmful to sensitive groups like children, the elderly, and people with lung or heart disease.

The Specifics: Ely's PM2.5 Reading

The reading of 163 for PM2.5 in Ely is concerning. This level of air pollution can cause a range of health issues, making it important to take immediate action. When PM2.5 levels are high, it means there are a lot of these tiny particles floating in the air, increasing the risk of inhaling them. High PM2.5 levels often lead to hazy conditions and reduced visibility, which can be a visual indicator of the pollution levels.

Health Impacts of High PM2.5 Levels

Understanding the health impacts of high PM2.5 levels is crucial for protecting yourself and your loved ones. PM2.5 particles are small enough to be inhaled deeply into the lungs, causing a variety of respiratory and cardiovascular issues. The severity of these effects can vary depending on the concentration of PM2.5 in the air, the duration of exposure, and an individual's overall health.

Respiratory Issues:

  • Asthma: High PM2.5 levels can trigger asthma attacks and make breathing difficult for those with asthma.
  • Bronchitis: Exposure to PM2.5 can irritate the airways and cause inflammation, leading to bronchitis symptoms such as coughing, wheezing, and shortness of breath.
  • Chronic Obstructive Pulmonary Disease (COPD): PM2.5 can exacerbate COPD symptoms, making it harder for individuals with this condition to breathe.
  • Respiratory Infections: Prolonged exposure to PM2.5 can weaken the immune system, increasing susceptibility to respiratory infections such as pneumonia and the flu.

Cardiovascular Issues:

  • Heart Attacks: High levels of PM2.5 can increase the risk of heart attacks, particularly in individuals with pre-existing heart conditions.
  • Strokes: PM2.5 can contribute to the formation of blood clots, increasing the risk of strokes.
  • Irregular Heartbeat: Exposure to PM2.5 can disrupt the normal rhythm of the heart, leading to irregular heartbeats.
  • High Blood Pressure: PM2.5 can cause inflammation and constriction of blood vessels, leading to elevated blood pressure.

Sensitive Groups at Higher Risk

Certain groups of people are more vulnerable to the health effects of PM2.5. These sensitive groups include:

  • Children: Children's lungs are still developing, making them more susceptible to the harmful effects of PM2.5. They also tend to be more active outdoors, increasing their exposure.
  • Elderly: Older adults often have pre-existing heart or lung conditions, which can be aggravated by PM2.5 exposure.
  • Individuals with Heart or Lung Conditions: People with asthma, COPD, heart disease, or other respiratory or cardiovascular conditions are at a higher risk of experiencing adverse health effects from PM2.5.
  • Pregnant Women: Exposure to PM2.5 during pregnancy has been linked to adverse outcomes such as premature birth and low birth weight.

It's vital for these sensitive groups to take extra precautions during air quality alerts to minimize their exposure to PM2.5.

How to Protect Yourself During High PM2.5 Levels

When air quality deteriorates, like in Ely right now, it’s crucial to take steps to protect your health. Here are some practical tips to help you minimize your exposure to PM2.5 and stay safe:

1. Stay Indoors:

The easiest way to reduce your exposure to PM2.5 is to stay inside as much as possible. When air quality is poor, indoor air is generally cleaner than outdoor air. Keep windows and doors closed to prevent outdoor pollutants from entering your home. If it’s comfortable to do so, avoid activities that can generate indoor air pollution, such as cooking with gas stoves or burning candles.

2. Use Air Purifiers:

Investing in an air purifier with a HEPA (High-Efficiency Particulate Air) filter can significantly improve indoor air quality. HEPA filters are designed to capture tiny particles, including PM2.5, removing them from the air you breathe. Place air purifiers in rooms where you spend the most time, such as your bedroom and living room. Remember to replace the filters regularly to maintain optimal performance.

3. Wear a Mask Outdoors:

If you must go outside when PM2.5 levels are high, wearing a mask can help protect your respiratory system. N95 masks are the most effective at filtering out fine particles. These masks are designed to fit tightly around your nose and mouth, creating a seal that prevents pollutants from entering. Surgical masks and cloth masks provide some protection, but they are not as effective as N95 masks.

4. Limit Outdoor Activities:

Avoid strenuous outdoor activities when air quality is poor. Exercise and other physical activities increase your breathing rate, causing you to inhale more air and, consequently, more pollutants. If you must exercise, opt for indoor activities or wait until the air quality improves. For sensitive groups, even light outdoor activities should be minimized.

5. Monitor Air Quality Reports:

Stay informed about the current air quality conditions in your area by monitoring local air quality reports. Websites like the EPA’s AirNow and local news outlets provide real-time data and forecasts. This information can help you plan your activities and take necessary precautions. Sign up for air quality alerts to receive notifications when air pollution levels are high.

6. Avoid Sources of Pollution:

Reduce your exposure to PM2.5 by avoiding sources of pollution. This includes areas with heavy traffic, industrial sites, and construction zones. If you are sensitive to air pollution, consider spending time in air-conditioned spaces, such as shopping malls or libraries, during peak pollution periods.

7. Take Care of Your Health:

Maintaining good overall health can help you better cope with air pollution. Stay hydrated, eat a balanced diet, and get plenty of rest. If you have respiratory or cardiovascular conditions, follow your doctor’s recommendations and keep your medications readily available.

8. Create a Clean Air Room:

Consider creating a clean air room in your home. This is a room where you can retreat when air quality is poor. Use an air purifier in this room, and ensure that windows and doors are sealed to prevent pollutants from entering. Spend time in your clean air room during peak pollution periods, especially if you are a member of a sensitive group.

Real-Time Monitoring and Resources

Keeping an eye on real-time air quality data is essential during events like this. There are several resources available to help you stay informed:
