Why low-level CO detection

Why Choose a Low-Level Carbon Monoxide Detector for Home, Travel, and Work?

Most store-bought CO alarms are built to the UL 2034 standard, which doesn't require them to sound until carbon monoxide reaches 70 ppm. Low-level CO monitors show you what's in the air much sooner.
