Ratings & Reviews+

First Alert Battery Carbon Monoxide Alarm is rated 4.4 out of 5 by 8.
Rated 5 out of 5 by from A Must Have One of 3 working units in my residence. This one sits in the furnace area. Comes ready to use, take it out of the box, activate the battery and it's on guard. Peace of mind is worth the price.
