People with respiratory illness should follow their physician`s advice for dealing with diminished air quality. N95 masks are effective at filtering out the majority of harmful air particulates. State air quality agencies highly recommend that no outdoor burning occur and that residential wood burning devices be limited as much as possible. According to state air quality agencies, prolonged periods of stagnant air can hold pollutants close to the ground where people live and breathe. Check with your local burn agency for any current restrictions in your area.
