Wood Fires and Breathing Problems in Grand Rapids, Michigan

Smoke from wood fires contains tiny particles and gases that can lower indoor and outdoor air quality and affect your health. In Grand Rapids—where many homes use wood stoves or fireplaces during long, cold Michigan winters—understanding wood smoke and how to reduce exposure is especially important for protecting your lungs and heart.

Wood Smoke in Grand Rapids: What’s in It?

Main Air Pollutants in Wood Smoke

The primary air pollutants in wood smoke are:

  • Fine particles (PM2.5) – very small particles that can travel deep into your lungs and even enter your bloodstream
  • Carbon monoxide (CO) – a colorless, odorless gas that can be deadly at high levels

Other harmful pollutants in wood smoke include:

  • Nitrogen oxides (NOx)
  • Benzene
  • 1,3-butadiene
  • Formaldehyde
  • Polycyclic (polyaromatic) aromatic hydrocarbons (PAHs)

These substances contribute to poor air quality in Grand Rapids, especially on cold, still winter nights when smoke can linger close to the ground in neighborhoods.

What Affects How Much Pollution Your Wood Fire Produces?

The amount of air pollution from a wood heater or fireplace depends on several factors:

  • How the heater is used
    • More pollutants are produced:
      • During start-up
      • When the fire is smoldering (low air, lots of smoke)
      • When airflow to the heater is restricted
  • Quality of the wood
    • Wet or “green” wood (high moisture content) creates much more smoke
    • Dry, seasoned hardwood burns hotter and cleaner
  • Condition and type of appliance
    • Old, poorly performing stoves or fireplaces release more smoke
    • Cracked seals, damaged doors, and warped parts can increase indoor leaks
  • Chimney and venting
    • Clogged or dirty chimneys reduce draft and increase smoke
    • Improper installation or poor venting can push smoke and CO back into the home

In neighborhoods across Grand Rapids—from Eastown and Alger Heights to the West Side—multiple homes using smoky wood stoves on cold nights can lead to noticeable smoke haze and odor, affecting everyone’s air.

Indoor vs Outdoor Wood Smoke Exposure

You can be exposed to wood smoke:

Inside Your Home

  • From your own:
    • Wood stove
    • Fireplace
    • Wood-burning insert
  • When:
    • The heater is poorly installed or vented
    • The chimney is clogged or not cleaned regularly
    • Doors, gaskets, or flue are not sealing properly

Outside Your Home

  • From:
    • Neighbors’ wood stoves and outdoor wood boilers
    • Backyard fire pits or bonfires
    • Outdoor recreational fires
  • Smoke can:
    • Drift into nearby homes and yards
    • Enter through windows, doors, or ventilation systems

In the Grand Rapids metro area, cold, calm winter evenings and temperature inversions can trap wood smoke close to the ground, making air quality worse—especially in low-lying areas and densely populated neighborhoods.

Who Is Most Sensitive to Wood Smoke?

Most healthy people recover quickly from short-term exposure to wood smoke. However, any exposure to fine particles can affect health, and some people are more vulnerable, including:

  • People with lung conditions:
    • Asthma
    • COPD (chronic obstructive pulmonary disease)
    • Chronic bronchitis
  • People with heart and vascular conditions:
    • Coronary artery disease
    • Heart failure
    • High blood pressure
  • People with diabetes
  • Older adults (over 65)
  • Infants and young children
  • Pregnant people
  • Smokers or former smokers

In Grand Rapids, where asthma and heart disease are common chronic conditions, wood smoke can be a significant trigger, especially during peak heating season (late fall through early spring).

Symptoms of Wood Smoke Exposure

Common Symptoms

Exposure to wood smoke may cause:

  • Coughing
  • Sore or scratchy throat
  • Runny or stuffy nose
  • Itchy, burning, or watery eyes
  • Headache
  • Mild shortness of breath or chest tightness

Worsening of Existing Conditions

People who are more sensitive may experience:

  • Asthma flare-ups (wheezing, coughing, chest tightness, difficulty breathing)
  • Worsening COPD symptoms (increased cough, mucus, shortness of breath)
  • Cardiovascular effects, such as:
    • Chest pain or pressure
    • Irregular heartbeat
    • Increased risk of heart attack or stroke in those with heart disease

If you live in Grand Rapids and have asthma or heart disease, wood smoke in your neighborhood can be a serious health concern, especially on days with poor air quality.

Carbon Monoxide (CO) and Wood Heaters

What Is Carbon Monoxide?

Carbon monoxide is:

  • Colorless
  • Odorless
  • Tasteless

It cannot be detected by smell and can build up indoors without warning.

CO levels in your home can rise when:

  • A wood stove, fireplace, or wood boiler is:
    • Poorly installed
    • Improperly vented
    • Damaged or leaking
  • The chimney or flue is blocked or not drafting properly
  • There is not enough fresh air in the room

Symptoms of Carbon Monoxide Exposure

At low to moderate levels, CO exposure can cause:

  • Headache
  • Dizziness
  • Fatigue or weakness
  • Trouble concentrating
  • Nausea (feeling sick)
  • Flu-like symptoms without a fever

At higher levels, CO exposure can cause:

  • Confusion
  • Drowsiness or difficulty staying awake
  • Chest pain
  • Shortness of breath
  • Loss of consciousness
  • Permanent damage to the brain and heart
  • Death

Be alert to symptoms such as unusual drowsiness, confusion, or sudden severe headache—these can indicate dangerously high CO levels and are a medical emergency.

If you suspect CO poisoning in Grand Rapids:

  • Leave the home immediately
  • Call 911
  • Do not re-enter until emergency services say it is safe

Other Wood Smoke Pollutants and Health Effects

In addition to fine particles and carbon monoxide, wood smoke contains:

  • Benzene
  • 1,3-butadiene
  • Formaldehyde
  • Polycyclic aromatic hydrocarbons (PAHs)

Health effects from these pollutants can include:

  • Eye, nose, and throat irritation
  • Headaches
  • Worsening of respiratory and nervous system conditions
  • Potential effects on:
    • Reproductive system
    • Developmental health (in children and during pregnancy)
    • Immune system

Studies show that some of these pollutants are known or suspected carcinogens (cancer-causing substances).

Health Precautions for Wood Heater Use in Grand Rapids

If you use a wood stove or fireplace in your Grand Rapids home, you can reduce health risks and neighborhood smoke by following these steps.

Choose Safer Equipment

  • Use heaters that meet current U.S. EPA emission standards or equivalent efficiency standards
  • Have your wood stove, insert, or fireplace:
    • Professionally installed according to Michigan building codes
    • Inspected and approved by a qualified technician or local building authority

Burn the Right Fuel

  • Burn only:
    • Dry, seasoned firewood
    • Untreated, unpainted wood
  • Never burn:
    • Plastics or foam
    • Painted, stained, or treated wood
    • Wood treated with copper chrome arsenate (CCA)
    • Garbage, cardboard, or glossy paper

These materials can release highly toxic fumes in addition to regular wood smoke.

Operate Your Heater Properly

  • Follow the manufacturer’s instructions carefully
  • Start fires with kindling and small pieces of dry wood
  • Keep the fire burning hot and bright, not slow and smoldering
  • Avoid “turning down” the air so low that the fire barely burns—this creates heavy smoke
  • Do not overload the firebox with wood

Maintain Your Heater and Chimney

  • Arrange for regular chimney cleaning (at least once a year before winter)
  • Have a professional:
    • Check for creosote buildup
    • Inspect for blockages, cracks, or leaks
    • Verify proper draft and ventilation
  • Replace worn door seals and gaskets

Ensure Adequate Fresh Air

To prevent CO buildup:

  • Allow fresh air into the room:
    • Keep interior doors in your home open to improve airflow
    • If there are no wall vents in the room with the heater, open a window slightly (a few centimeters) when the stove is in use
  • Avoid using exhaust fans (bathroom, kitchen) that can interfere with draft while the stove is operating, unless you have adequate make-up air

Consider Cleaner Heating Options

If wood smoke is a problem in your home or neighborhood:

  • Consider switching to:
    • High-efficiency gas furnace or flued gas heater
    • Electric heat pump or baseboard heating
  • If you must use wood, consider upgrading to a newer, low-emission, EPA-certified wood stove

These options can significantly reduce indoor and outdoor air pollution in Grand Rapids neighborhoods.

Protecting Yourself During Times of Heavy Outdoor Wood Smoke

On some winter days or nights in Grand Rapids, outdoor wood smoke from multiple homes, fire pits, or nearby rural burns can become noticeable.

To reduce health risks when outdoor wood smoke is a problem:

  • Check local air quality reports
    • Look for updates from the Kent County Health Department, Michigan Department of Environment, Great Lakes, and Energy (EGLE), or local Grand Rapids weather and news outlets
  • Stay indoors when smoke is heavy
    • Keep windows and external doors closed
    • Use an air purifier with a HEPA filter if available
  • Reduce outdoor physical activity
    • Avoid strenuous exercise outdoors when you can see or smell smoke
  • Use cleaner indoor air practices
    • Avoid burning candles or incense
    • Do not smoke indoors
    • Avoid vacuuming without a HEPA filter, which can stir up particles

If You Have Heart or Lung Disease

If you live in Grand Rapids and have asthma, COPD, or heart disease:

  • Take your prescribed medications as directed
  • Keep your rescue inhaler (for asthma) or other emergency medications with you
  • At the first sign of symptoms (coughing, wheezing, chest pain, unusual shortness of breath):
    • Stop physical activity
    • Move to a cleaner indoor environment
    • Follow your asthma or COPD action plan if you have one
  • Seek medical advice if symptoms are:
    • Getting worse
    • Not improving with your usual treatment
    • Severe or sudden

Call 911 immediately if you experience:

  • Severe difficulty breathing
  • Chest pain or pressure
  • Confusion, fainting, or signs of a possible heart attack or stroke
