FAQ:

Q: What is a good level for a carbon monoxide detector?

A: For the best carbon monoxide detector placement, place them at knee level – often the height of a sleeper’s nose and mouth. If you have children and pets, place them at chest height or as high as needed to keep them out of reach.

Q: Do you really need a carbon monoxide detector?

A: Because the gas has no scent or color, it’s important to have a carbon monoxide detector in the home. Unless all of your appliances are run with electricity or batteries, you need a carbon monoxide detector to keep yourself, your family, and your pets safe.

Q: Where is the best place to mount a CO detector?

A: The best bet is to mount your carbon monoxide detector on the ceiling just like you would with a typical smoke detector. Keep your CO detector mounted away from bathrooms, laundry rooms, or any other area that gets more humid than the rest of the house.

Q: How much does a carbon monoxide detector cost?

A: Typical costs: Stand-alone carbon monoxide detectors typically cost $20-$50. Some carbon monoxide detectors are combined with smoke detectors. Carbon monoxide alarms for the hearing impaired frequently include strobe lights and cost more than typical alarms.
