 Many Alaskans rely on burning wood to offset the high cost of energy. But burning wood produces smoke that's made up of tiny particles called PM2.5, which travel through the air, get into the eyes, and into the deep parts of the lungs, which can result in reduced lung function, asthma, bronchitis, and respiratory infections. Burn wise and breathe easy by burning properly seasoned wood, having your wood stove inspected every year, and changing out your old wood stove with one that uses cleaner burning technology.
