BUTTE COUNTY, Calif. - The Butte County Air Quality Management District (BCAQMD) and Butte County Public Health Department (BCPHD) would like to remind community members that wildfire smoke in Butte County is possible throughout the dry season. Wildfire smoke can be created
locally or travel hundreds of miles to reach our area.

The major air pollutant of concern during wildfires is fine particulate matter (PM2.5). While all persons may experience varying degrees of symptoms, people at increased risk include young children, older adults, pregnant women, people who smoke, people who work outside, and people with respiratory conditions. Symptoms of exposure to wildfire smoke may include but are not limited to, coughing, watery and itchy eyes, headaches, and difficulty breathing.

BCAQMD and BCPHD recommend residents take the following steps to reduce your exposure to smoke during future wildfire smoke events:

  • Check with your doctor about what you should do during smoke events if any family member has heart or lung disease, including asthma. Have a plan to manage your condition.
  • Consider keeping several spare high-efficiency filters in storage if you have a central air system. HVAC filters should be rated MERV-13 (or equivalent) or higher to filter out smoke particles.
  • Ask your air conditioning service professional how to close the fresh-air intake if your central air system or room air conditioner has one.
  • Consider purchasing one or more portable high-efficiency (or HEPA) filters if you cannot filter indoor air through a central air system to help create one or more “clean rooms.” Avoid air purifiers that generate ozone.
  • Know where to find air quality information. The Butte County Air Quality Management District’s website ( has daily air quality forecasts as well as links to real-time air quality data. is the primary resource for air quality conditions throughout the nation.

Cooler and cloudier today, record heat expected today, then the chance for high fire danger or showers next week.
