CarbonOne Safe is a plug-in home monitor. It watches the air for carbon monoxide (CO), natural gas and propane, and shows you a live reading on its screen. If levels get unsafe, it sounds a loud alarm. Here is how it works, in plain words.
Many basic alarms only show a green light until they go off. CarbonOne Safe shows the actual CO number, in parts per million (ppm), starting from zero. The CDC suggests considering a detector with a digital readout, because you can see a small rise before it becomes a problem.
There are no tools and no wiring. Plug it into a standard wall outlet and it switches on by itself. Setup takes seconds. See our setup guide for the best spots.
CarbonOne Safe has a 5-year rated life. The CDC also advises replacing CO detectors as the maker says, or every 5 years.
Safety groups like the NFPA recommend carbon monoxide alarms that carry a testing lab's label (look for UL 2034) outside each sleeping area and on every level of your home. CarbonOne Safe works well alongside them: your alarms protect each level, and CarbonOne gives you an easy live reading near gas appliances.
