How To Protect Yourself From Wildfire Smoke as St. Cloud Air Quality Hits Hazardous Levels

(KNSI) — Wildfire smoke has pushed air quality in the St. Cloud area to the hazardous maroon category, a level the state considers dangerous for everyone, and the Minnesota Department of Health has advice for getting through it.

The MDH says people should stay indoors when possible, keep windows and doors closed, and use an air filter. The department recommends running the air conditioning on recirculate with the fresh-air intake closed, using a MERV 13-rated filter or higher in the home’s HVAC system and changing it monthly or more often during periods of poor air quality. Portable HEPA air cleaners also help. Another option is a homemade Corsi-Rosenthal Box air purifier, built from a box fan, duct tape and filters.

For those without air conditioning, the MDH recommends going to an air-conditioned public space, such as a community center or public library.

For anyone who has to be outdoors, including people who work outside, health experts strongly encourage limiting time spent outside and cutting back on activity, especially exercise, and taking breaks in clean indoor air. Inside a vehicle, the ventilation system should run on recirculate with the windows and sunroof closed.

The MDH also says to take it easy, and take care of yourself and others by paying attention to changes in breathing and overall health such as coughing, scratchy throat, stinging eyes and sinus irritation. More dangerous signs of exposure are shortness of breath, wheezing, chest pain, rapid heartbeat, severe fatigue and headaches. The department urges people to check on friends, family and neighbors, especially those who are older and live alone.

For people with asthma or conditions like COPD, MDH experts recommend keeping a rescue inhaler close by and following a medical or asthma action plan.
