Carbon monoxide (CO) is a silent, odorless, and tasteless gas with lethal potential, and its threat becomes more pronounced during the change in seasons when colder weather prompts the use of heaters in our homes.
CO emissions can emanate from a variety of sources, including power generators, stoves, lanterns, grills, wood-burning fireplaces, gas ranges, furnaces, and even the vehicles we rely on daily. If CO accumulates indoors or inside your vehicle, it can swiftly incapacitate, often without any warning. Shockingly, over 400 people in the United States lose their lives to accidental carbon monoxide poisoning each year, as reported by the Centers for Disease Control and Prevention. The most common symptoms of CO poisoning encompass headaches, dizziness, weakness, nausea, vomiting, chest pain, and confusion.
Here, we present our recommendations for carbon monoxide detectors, along with crucial guidance to consider before you make a purchase.
