Q8: Does CO Shield monitor indoor CO levels?
A: No. CO Shield is not a substitute for an indoor carbon monoxide alarm. CO Shield will NOT detect in-home CO levels. To monitor indoor CO levels, follow the manufacturer’s instructions to install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with battery back-up.
