How High-Efficiency Air Filters Can Help Protect Indoor Air Quality During Wildfire Season

Wildfires are increasingly becoming a threat not only to landscape and property but also to air quality across vast regions. While flames may burn thousands of miles away, the smoke from wildfires can significantly impact the air quality of distant communities. These traveling plumes carry harmful pollutants that degrade outdoor air and infiltrate indoor environments. As the frequency and intensity of wildfires escalate, dangers imposed on indoor air quality (IAQ) and human health have grown.

One of the most harmful byproducts of wildfire smoke is fine particulate matter. These microscopic particles are small enough to penetrate deep into the body, contributing to a range of health issues. Wildfires also release gases like carbon monoxide and volatile organic compounds, which complicate respiratory issues and contribute to ground-level ozone formation.

Smoke from the recent Canadian wildfires, for example, has spread more than 5,000 miles, reaching parts of Russia and Europe and releasing over 56 megatons of carbon. The smoke concentrations led to poor air quality across several U.S. states, including Michigan, Illinois, Iowa and Wisconsin.

High-efficiency air filtration is one essential strategy for protecting IAQ during wildfire events. Filters with higher Minimum Efficiency Reporting Value (MERV) ratings are designed to capture finer particles, significantly reducing the concentration of smoke and pollutants indoors. When paired with well-maintained HVAC systems, these...
