Buying Guide: Choosing a Kitchen Alternative

Keep these points in mind before you buy.

CO alarm vs. gas alarm

A CO alarm senses carbon monoxide from burning fuel. An explosive gas alarm senses natural gas or propane leaks. Combo units like Kidde’s do both.

CO-only or smoke and CO combo

Combo alarms save ceiling space and batteries; separate alarms let you place CO detectors lower or plug them into outlets.
