How Do Wildfires Affect Air Quality?

In December, breathe freely. Comfortable temperatures that are between 50 and 60 degrees don’t make you overheat. Increasing precipitation eliminates dry-season issues. Additionally, the ocean breeze blows fresh, cool air to the coast. Late summer and fall are commonly hot and dry, creating danger.

In Los Angeles, 2021 wildfire season is record-setting. More than 1,200 acres of forests have burned. Thousands of Angelinos had to evacuate. Are you still staying at home? If there is no house destroying risk, apart from fast-moving bursts of fire, it’s possible.

Meanwhile, you are to:

  • stay indoors;
  • keep all doors and windows closed;
  • recognize emergency alerts;
  • have a sufficient drinking water stock at hand.
  • turn off all air circulation systems.

Contaminated outdoor air during a wildfire becomes dangerous and unhealthy. It contains toxic chemical compounds and byproducts. It easily gets inside through small cracks or joints. AC units that allow outdoor air intake may put you at higher risk.

Wildfires make difference. They induce the release of toxic contaminants and gases like carbon monoxide. EPA recommendations are practical in this case. What about your available AC systems and devices? Some of them help you to filter the smoke. The others may absorb it from outside. A simple comparison clears up your doubts.
