Carbon Monoxide Detectors BUYING GUIDE

  • KEY CONSIDERATIONS

    Digital Display

    Some carbon monoxide detectors have digital displays that show the current concentration of CO in parts per million (PPM), and may show other readings such as temperature and humidity. All detectors certified by the Underwriters Laboratory (UL) must sound an alarm when concentrations reach 70 PPM, which is considered unsafe for the average person, though levels as high as 30 PPM can be dangerous for children, pregnant women, or those with heart issues. Detectors with digital displays can also keep you aware of spikes in CO levels while you’re away from home.

    Power Source

    Carbon monoxide detectors are powered in two ways: with batteries or through a wired connection. Battery powered detectors have the benefit of being cheaper and more portable, as well as the ability to remain working during a power failure. However, they will need their batteries replaced every six months. Hardwired detectors require little to no maintenance, but require an experienced technician to install them correctly. These models carry the added benefit of being able to be linked together to form an alarm network for your entire home or business.

    Battery Backup

    If you decide to go with a hardwired carbon monoxide detector, make sure that it comes with an adequate backup battery in case of power failure in your home or business. Because these batteries are only used in case of emergency, they tend to last the lifetime of the detector – anywhere from five to 10 years.

    Smart Connectivity

    With advances in wireless technology, certain “smart” carbon monoxide detectors have added alarm connectivity features to battery-powered detectors. This allows you to place multiple detectors on each floor of your home and sync them so when one detector trips, they will all sound an alarm. Be prepared to pay more for this convenience.

    Date of Manufacture

    All UL-certified carbon monoxide detectors will have a printed date of manufacture on their packages. Because the sensors on these detectors are sensitive and wear out over time, it’s important to only use ones that are as close to this date as possible.

  • PRICE BREAKDOWN

    Basic carbon monoxide detectors start around $25 to $30 for battery-powered models without a digital display. Prices increase as the number of features increase, with hardwired and portable devices that utilize digital displays with temperature and humidity readings typically going for around $50. Smart carbon monoxide detectors with wireless connectivity and mobile-app capability can be had for $99 and up, but are really only worth it if you’re willing to commit to purchasing multiple units. Truly portable, professional-grade carbon monoxide detectors with extended sensor ranges start around $170, and can reach close to $200 with added waterproof and shockproof features.

Other Considerations

  • Annoying self-testing alarm. Some customers complain that the First Alert PRC700 Smoke and Carbon Monoxide Alarm will conduct self-tests randomly, sometimes in the middle of the night.
  • Not approved in Massachusetts. At least one user claims that the First Alert PRC700 Smoke and Carbon Monoxide Alarm is not approved for use in the state of Massachusetts because it does not have a voice alert that describes if it is smoke or CO gas being detected.
  • Short life span. While the specifications for the First Alert PRC700 Smoke and Carbon Monoxide Alarm say it has a 10-year limited warranty, many customers found that their units only lasted two to three years before indicating they needed to be replaced.

Best Hardwired Carbon Monoxide Detector

why buy?

Many brands of carbon monoxide detectors offer both battery powered and hardwired models for your convenience. The main difference is that hardwired carbon monoxide detectors must be connected to your home’s electrical system by a professional, making them virtually maintenance-free. They can be wired together to create a network of alarms that will all sound even if only one detector is tripped, something most battery powered detectors can’t do. They tend to be more accurate and offer 24/7 monitoring by emergency service centers – though this tends to make them more of an upfront investment.

Top Pick

  • Battery life. Because the Kidde KN-COB-IC Hardwire Carbon Monoxide Alarm is hardwired into the building’s electrical system, the backup battery is only used during power outages. Reviewers say this means they rarely hear the “low battery” alarm.
  • Distinct alarm sound. Several customers mention that the Kidde KN-COB-IC Hardwire Carbon Monoxide Alarm has a unique alarm tone that sets it apart from the other smoke or heat alarms in their homes or businesses.

Other Considerations

  • Discoloration. A handful of users write that the Kidde KN-COB-IC Hardwire Carbon Monoxide Alarm has a plastic housing that turns yellowish-brown after a few years.
  • One-way interconnectivity. Customers who have the Kidde KN-COB-IC Hardwire Carbon Monoxide Alarm connected with other detectors say the alarms don’t work as intended. When other alarms go off, this device will also sound, but if this CO detector is tripped, it will not send a signal to make other devices (such as smoke or heat alarms) sound alarms. It only works that way with other CO detectors.

Best Smoke and Carbon Monoxide Detector

why buy?

Combination smoke and carbon monoxide detectors are designed to guard against both smoke and CO inhalation without the need to install additional detectors. Many of these products have multiple LED alerts to signal which threat is detected, and come in battery operated or hardwired versions. However, what they offer in convenience, they tend to lack in features, taking a more “middle of the road” approach to smoke and carbon monoxide detection.

  • LED indicator. Customers appreciate that the Kidde KN-COSM-BA Combination Smoke/Carbon Monoxide Alarm has a green LED indicator light that blinks every 60 seconds to let them know it’s on and working properly. The red indicator light blinks faster during an actual alarm.
  • Hush mode. Many users like that the Kidde KN-COSM-BA Combination Smoke/Carbon Monoxide Alarm can be quickly silenced with the press of a button, which comes in handy if there’s a false alarm.

Other Considerations

  • Expired detectors. Some reviewers complain that they were sold out-of-date detectors. Always check the packaging and alarm itself to determine when it was manufactured and return units that are too old.
  • Chews through batteries. Several customers say that the Kidde KN-COSM-BA Combination Smoke/Carbon Monoxide Alarm requires a lot of power, with two AA batteries lasting less than a month in some cases.

Best Carbon Monoxide Detector for Vehicles

why buy?

Just as you’d expect to have a carbon monoxide detector in your house, you should have one to protect your recreational vehicles as well. In fact, the Recreation Vehicle Industry Association requires that any vehicle equipped with a generator – such as a motor home, caravan or houseboat – have a working carbon monoxide detector installed. Luckily, these models are very simple to install, requiring only a 9V or 12V battery depending on their size. Battery life is typically around one year, and most models will flash an LED warning light when it needs to be replaced.

  • LED indicator lights. The Safe-T-Alert 40-442-P-WT Propane/LP Gas Detector uses indicator lights to clearly alert users to danger or specify when the unit needs to be replaced, which many customers say they appreciate.

Other Considerations

  • Requires DC wiring knowledge. Some reviewers say they were confused during installation because they are not familiar with wiring devices like the Safe-T-Alert 40-442-P-WT Propane/LP Gas Detector that use direct current (DC) instead of alternating current (AC).
  • Limited lifespan. According to a few reviewers, all carbon monoxide detectors with the “-P” designation (like this one) are designed to stop working only five years after being connected to a power source. This is apparently based on new RV regulations.

Best Portable Carbon Monoxide Detector

why buy?

Portable carbon monoxide detectors are especially useful for everyone from frequent travelers to construction and building maintenance technicians. Though they tend to be more expensive than the average home unit, they come with many more features built-in, including waterproofing, a larger CO sensor range and additional sensors for humidity and temperature. Portable carbon monoxide detectors are battery powered, and can last several years with regular use. Typically, they are used in industrial applications by firefighters and HVAC technicians, but can also be handy for those that spend a lot of time in hotels and other temporary housing that may lack built-in carbon monoxide detectors.
