The 50 Top Carbon Monoxide Detectors

by Caitlin McCormack | Last Updated Feb. 15th, 2016

Carbon monoxide (CO) is a colorless, odorless gas produced by combustion fumes originating from a stove or your home’s heating system, which can cause sudden illness or even death.

Common symptoms of carbon monoxide poisoning include: nausea, vomiting, headaches, weakness, dizziness, chest pain and confusion. If CO levels rise quickly or exposure continues, it can lead to unconsciousness and fatality.

However, by simply installing a carbon monoxide detector in your home, you and your family can be alerted to dangerous levels of carbon monoxide and escape to fresh air and safety before something tragic happens.

In fact, depending on where in America you live, it might already be the law that you need to have a carbon monoxide detector installed in your home – and more and more new home constructions are making it mandatory to install carbon monoxide detectors as well.

Given that carbon monoxide poisoning is one of the most common preventable causes of death in the United States, it makes sense to install a carbon monoxide detector in your home to help keep your family safe.
