Carbon Monoxide Detectors

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be deadly if inhaled in high concentrations. It is produced by the incomplete combustion of fuels such as gas, oil, wood, and coal. Carbon monoxide poisoning can cause symptoms such as headaches, dizziness, nausea, and fatigue, and can lead to unconsciousness and even death.

A carbon monoxide detector is an essential safety device that can alert you to the presence of this dangerous gas in your home. In this buying guide, we will discuss the different types of carbon monoxide detectors, key considerations to keep in mind when choosing one, important features to look for, typical prices, and tips for using and maintaining your detector.

There are several types of carbon monoxide detectors available on the market, including:

1. Biomimetic sensor detectors: These detectors use a gel that changes color when it absorbs carbon monoxide. They are affordable and reliable, but may not be as sensitive as other types of detectors.

2. Electrochemical sensor detectors: These detectors use electrodes to detect carbon monoxide in the air. They are highly sensitive and accurate, but can be more expensive.

3. Metal oxide semiconductor detectors: These detectors use a silica chip that reacts with carbon monoxide. They are affordable and durable, but may not be as sensitive as other types of detectors.

4. Photoelectric sensor detectors: These detectors use a light source and a sensor to detect carbon monoxide. They are effective at detecting smoldering fires as well as carbon monoxide, but can be more expensive.

5. Combination detectors: These detectors combine carbon monoxide detection with smoke detection in a single unit. They are convenient and can save space, but may be more expensive and may not be as sensitive as standalone detectors.

When choosing a carbon monoxide detector, there are several key considerations to keep in mind:

1. Power source: Carbon monoxide detectors can be powered by batteries, plug-in outlets, or hardwiring. Battery-powered detectors are portable and easy to install, but require regular battery replacement. Plug-in detectors are easy to use and do not require battery replacement, but may not work during power outages. Hardwired detectors are the most reliable and do not require battery replacement, but require professional installation.

2. Sensitivity: The sensitivity of a carbon monoxide detector is measured in parts per million (ppm). Look for a detector that can detect low levels of carbon monoxide (30 ppm or less) and has an alarm that sounds at 70 ppm or less.

3. Certification: Look for a carbon monoxide detector that is certified by a reputable organization such as Underwriters Laboratories (UL). This ensures that the detector has been tested and meets safety standards.

4. Features: Look for features such as a digital display, a peak level memory, and a test/reset button. These features can make it easier to use and maintain your detector.

Here are some features to look for when choosing a carbon monoxide detector:

1. Digital display: A digital display can show you the current and peak levels of carbon monoxide in your home.

2. Peak level memory: This feature can store the highest level of carbon monoxide detected by the detector.

3. Test/reset button: This button allows you to test the detector and reset it after an alarm has sounded.

4. Interconnectivity: This feature allows multiple detectors to communicate with each other and sound alarms simultaneously.

5. Smart features: Some carbon monoxide detectors have smart features such as Wi-Fi connectivity and mobile alerts.

The price of a carbon monoxide detector can vary depending on the type, features, and brand. Biomimetic sensor detectors can cost as little as $20, while electrochemical sensor detectors can cost $50 or more. Combination detectors can cost $50 to $100 or more. It is important to choose a detector that fits your budget and meets your needs.

Here are some tips for using and maintaining your carbon monoxide detector:

1. Install a carbon monoxide detector on every floor of your home and near sleeping areas.

2. Test your detector regularly and replace batteries as needed.

3. Replace your detector every 5 to 7 years or according to the manufacturer's instructions.

4. Keep your detector clean and free of dust and debris.

5. Know the symptoms of carbon monoxide poisoning and seek medical attention if necessary.

Q: Do I need a carbon monoxide detector if I have a smoke detector?

A: Yes, smoke detectors and carbon monoxide detectors serve different purposes. A smoke detector detects smoke from a fire, while a carbon monoxide detector detects carbon monoxide from a fuel-burning appliance.

Q: Can a carbon monoxide detector detect natural gas leaks?

A: No, a carbon monoxide detector cannot detect natural gas leaks. You will need a separate gas detector for that.

Q: Can I install a carbon monoxide detector myself?

A: Yes, you can install a battery-powered or plug-in carbon monoxide detector yourself. However, hardwired detectors should be installed by a professional.

Q: How often should I replace my carbon monoxide detector?

A: Carbon monoxide detectors should be replaced every 5 to 7 years or according to the manufacturer's instructions.

Q: What should I do if my carbon monoxide detector goes off?

A: If your carbon monoxide detector goes off, evacuate your home immediately and call 911.
