The Gases You Can’t See Are Often the Most Dangerous

Carbon monoxide is the most immediately life-threatening indoor air pollutant. It is colorless, odorless, and produced by any combustion source — gas furnaces, wood stoves, fireplaces, gas ranges, and vehicles in attached garages.

Carbon dioxide, while not immediately toxic, is a critical ventilation indicator. When CO2 rises above 1,000 ppm — common in sealed Alaska homes during winter — occupants experience fatigue, difficulty concentrating, and headaches.

Every Anchorage Home with Any of the Following Should Be Tested:

• Wood stove or fireplace
• Gas furnace, water heater, or range
• Attached garage
• Multiple occupants and limited winter ventilation
• Symptoms of fatigue that worsen during winter
