Where There's Smoke There's Poor IAQ

Wildfires are burning across the country in increasing frequency and severity. Climate change has created warmer and drier climates, particularly in the West. These conditions create a year-round environment where wildlife activity is more likely. This reality is reflected in the numbers. In 2026, the United States reported 39,520 fires, damaging 3,633,827 acres—a record high.

When the outdoor air is contaminated, indoor environments are threatened. An indoor air quality (IAQ) study found that interior spaces retain harmful volatile organic compounds (VOCs) following a fire. The smoke, chemicals, and odors that linger long after a wildfire can impact the respiratory health of building occupants. Moreover, poor IAQ can also affect productivity by 3 to 9 percent, factoring into employee absenteeism rates.

The Environmental Protection Agency (EPA) recommends the following guidelines to safeguard indoor environments by addressing SMOKE:

S – Stay Informed
Follow advisory guidance on outdoor air quality during wildfire events.

M – Minimize exposure
Preserve IAQ by implementing and monitoring high-efficiency HVAC filters.

O – Optimize systems
Monitor filtration systems or air conditioners to prevent contamination.

K – Keep supplies
Gather, utilize, and restock emergency supplies like extra air filters, N95 respirators, and more.

E – Establish clean environments
Maintain safe and healthy indoor spaces by keeping doors and windows closed.
