How to Choose Carbon Monoxide Detectors
Consider Power Source
Think about how the carbon monoxide detector will be powered. Battery-powered detectors are portable. Plug-in models provide constant power. A mix of both offers flexibility.
Check Alarm Volume
Look for a detector with at least an 85 dB alarm. This volume is loud enough to wake you up during the night. The louder the alarm, the better the safety.
Look for Features
Advanced features like peak level memory are helpful. This feature shows the last detected carbon monoxide levels. It’s useful to know if there has been a CO issue recently.
Size and Portability
If you need a carbon monoxide detector for multiple locations, choose a portable model. Ensure it fits easily in your garage or anywhere else you might want to use it.
Installation Ease
Choose a model that is easy to install. Some simply plug into an outlet, while others need mounting. Consider your comfort level with installation and choose accordingly.
