Best Carbon Monoxide Detectors Buying Guide
Before choosing the best carbon monoxide detector you should consider the following options:
1. Battery-powered or plug-in: Most carbon monoxide detectors are battery-powered. If your home uses gas for cooking or heating, you should buy a carbon monoxide detector that has a long-lasting battery.
If your home has a fixed fuel-fired heater, then a plug-in detector will work. A plug-in detector will usually have a battery as a backup.
2. Interconnected or single: An interconnected detector will be part of a network with other detectors in your home. All of the interconnected detectors are triggered at the same time.
They are useful in large homes where there may be a gas leak in one part of the house and the occupants could move to a different area of the house and be exposed to the gas.
There are two types of interconnected detectors: D link and parallel link. A D link detector will sound even if one of the other detectors in the network is not working. A parallel link detector will only sound if all of the other detectors in the network are triggered.
3. Audible alarm or visual alarm: Not all carbon monoxide detectors have a sound alarm. If your home is completely silent, such as if you are deaf, then you should buy a detector with a visual alarm.
But if you have a working alarm in your house, such as a smoke alarm, then a detector without a sound alarm will be sufficient.
4. Number of beeps: Not all carbon monoxide detectors make a noise when they detect the gas in the home. Some have a visual alarm and some have both a sound alarm and a visual alarm.
If your detector has a sound alarm, then you should buy one with a number of beeps to indicate the level of danger. The more beeps, the higher the level of danger.
What else you should know about the best carbon monoxide detectors
1. What are the best carbon monoxide detectors on the market?
Some of the best carbon monoxide detectors on the market are the Kidde Nighthawk Plug-In Carbon Monoxide Alarm, the First Alert CO606 Carbon Monoxide Alarm, and the Honeywell 5808W3 Wireless Photoelectric Smoke and Heat Alarm.
2. How do carbon monoxide detectors work?
Carbon monoxide detectors work by measuring the amount of carbon monoxide in the air. If the level of carbon monoxide gets too high, the detector will sound an alarm to warn people to get out of the area.
3. What are the symptoms of carbon monoxide poisoning?
The symptoms of carbon monoxide poisoning are headaches, dizziness, nausea, shortness of breath, and confusion.
4. How can I prevent carbon monoxide poisoning?
There are a few things you can do to prevent carbon monoxide poisoning:
– Make sure all fuel-burning appliances in your home are properly vented.
– Do not use a gas stove to heat your home.
– Do not use a charcoal grill indoors.
– Do not leave a car running in an attached garage, even if the garage door is open.
5. What should I do if my carbon monoxide detector goes off?
If your carbon monoxide detector goes off, you should leave the house immediately and call 911.
