MADISON, WI — With the onset of cooler temperatures, people across the country are winterizing their homes — sealing windows and servicing their furnace. Aprilaire notes that they should also be testing and, if necessary, replacing their carbon monoxide (CO) alarms.
Carbon monoxide poisoning is the number one cause of unintentional poisoning deaths in the world, says the company. There are many sources of CO, and it is not a concern that is exclusive to the winter months. Carbon monoxide poisonings and fatalities happen year-around.
