How to Test Carbon Monoxide Detectors

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced whenever any fuel is burned. Because it is impossible to see, taste, or smell, CO can kill you before you are even aware it is there. That is why it is important to have working carbon monoxide detectors in your home.

There are two types of carbon monoxide detectors: battery-operated and plug-in. Battery-operated detectors can be placed anywhere in your home, while plug-in detectors must be plugged into an outlet.

It is recommended that you test your carbon monoxide detectors once a month to make sure they are working properly. There are two ways to test a carbon monoxide detector: with a CO detector tester or by using a lit candle.

Next, hold the lit candle about 6 inches away from the detector and wait for the alarm to sound.
