How to Keep Wildfire Smoke Out of Your House—and Why It’s So Important
Wildfire smoke is a complex mixture of harmful pollutants, including fine particulate matter (PM2.5), carbon monoxide, volatile organic compounds (VOCs), and other toxic gases.
These pollutants are small enough to penetrate deep into the respiratory system and even enter the bloodstream, causing significant health concerns.
Entry Points: How Wildfire Smoke Gets Into Your House
Wildfire smoke can enter homes through open windows, doors, and poorly sealed gaps around vents, chimneys, and foundations. Once inside, these particles linger, making it challenging to maintain a healthy indoor environment without proper mitigation measures.
Health Risks When Wildfire Smoke Enters Your House
The infiltration of wildfire smoke leads to poor indoor air quality, which can cause or exacerbate a range of health issues, particularly for vulnerable groups like children, the elderly, and those with pre-existing respiratory or cardiovascular conditions.
Symptoms may include wheezing, coughing, shortness of breath, and chest pain. Prolonged exposure can lead to more severe complications, emphasizing the importance of effective indoor air quality management.
