How can I tell if a CO alarm is approved?

CO alarms are approved by an independent testing company such as Underwriters’ Laboratories (UL).  Be sure to look for the approval label when buying CO alarms. Most of the CO alarms currently sold do meet these standards but it is a good idea to check and make sure they meet the standard before you purchase the alarms.
