How we chose the best carbon monoxide detectors If your CO alarm goes off, immediately go outside and only reenter when emergency responders say it’s safe. And 800 PPM of CO can be fatal within an hour. Triple that to 150 PPM of CO and you may experience symptoms in as little as 2 – 3 hours. According to this chart, it may take between 6 – 8 hours for physical symptoms to manifest when exposed to 50 PPM of CO. If a dangerous level of CO is detected, an audible alarm, usually 85 decibels, will sound.Ĭarbon monoxide is measured in parts-per-million (PPM). While some models feature different components, they generally feature a silicon microchip that sends an electronic charge to other parts of the detector. How does a carbon monoxide detector work?Ĭarbon monoxide detectors aren’t as complicated as they seem. For ways to prevent carbon monoxide poisoning, particularly in winter when it’s most common, we have some tips on how to protect yourself. Using a battery-operated carbon monoxide detector is considered one of the most effective ways to protect yourself from CO poisoning. And though symptoms of CO poisoning include headaches, dizziness, chest pain, and vomiting, victims are unaware that they’re being poisoned until it’s too late. In a gas-filled room, inhaling carbon monoxide can render you unconscious and kill you within a few minutes, according to reports from the CDC and OSHA. If inhaled, carbon monoxide blocks your ability to absorb oxygen into your blood, and by extension vital organs including your heart and brain. Best budget: Kidde Carbon Monoxide DetectorĬarbon monoxide is an odorless, tasteless, poisonous gas that builds up when you burn fuel like gas, wood, or coal.Best smart: Google Nest Protect Smoke and Carbon Monoxide.Best plug-in detector: First Alert CO615.Best smoke and carbon monoxide detector: Kidde Smoke & Carbon Monoxide Detector.Best overall: Kidde Nighthawk Carbon Monoxide Detector.Whether you’re replacing a faulty CO alarm or upgrading an older home to meet local health codes, these are the best carbon monoxide detectors. If you don’t have one, they’re affordable and very easy to install. There’s a chance you already have a carbon monoxide detector at home, as they’re sometimes (but not always) built into smoke detectors. Without one, you risk exposing yourself and your loved ones to accidental CO poisoning, which kills more than 400 Americans yearly, according to the Centers for Disease Control (CDC). ![]() A carbon monoxide detector, or CO alarm, is an essential safety device for renters and homeowners. ![]()
