European Standards
It is essential to only use a CO alarm that is officially approved to EN50291-1:2010 - The European Standard for Domestic Carbon Monoxide Alarms. Without this certification, there is no guarantee that a CO alarm is capable of doing the job it is designed to do. This means that if a CO leak occurs, you may not be alerted to it, putting your life and your family's lives at risk. Always ensure you avoid using a device that does not have this accreditation or a device that states it is "designed to meet EN50291-1:2010" as only an official approval will guarantee a device's performance.
