The Best SimpliSafe Carbon Monoxide Detector

SimpliSafe’s Carbon Monoxide Detector is a lifesaving device that detects the poisonous gas in the air and alerts you to the danger before it’s too late. It’s important to remember that carbon monoxide can’t be seen, smelled, or tasted but it can kill in minutes. Our carbon monoxide detector’s long-lasting battery is easy to replace and doesn’t require expensive wiring.

Carbon monoxide (CO) is an odorless, colorless gas that can be deadly. Don’t let your family become a statistic. Keep them safe with the SimpliSafe Carbon Monoxide Detector. This plug-in detector monitors the air for CO and alerts you when it’s detected, so you can take action before it’s too late. It also detects smoke and other threats, so you have a complete home security system at your fingertips.

Why Is Carbon Monoxide Dangerous

One of the most dangerous substances in the air, carbon monoxide isn’t caused by normal cabin heating or your furnace malfunctioning. It’s produced by car exhaust, poorly vented gas appliances and natural gas pipes. Since carbon monoxide doesn’t have any odor, it’s spread is faster than many other poisonous gases. It can easily get inside your home, even if you’re not aware it’s there.

CO is extremely dangerous to people and animals. Carbon monoxide poisoning can kill you in as little as a few hours. The SimpliSafe Carbon Monoxide Detector Most carbon monoxide detectors detect CO using carbon monoxide sensors. This device, however, includes a battery backup, so if your power is out, it’s still working.

How Well Does It Work

The way I see it, the carbon monoxide detector has a safe range of 20ppm to 400ppm. When it’s in the middle of that range, it will not sound and will not send a signal to the phone. I do not have an actual carbon monoxide detector in my house, but the SimpliSafe worked very well.

SimpliSafe Carbon Monoxide Detector Review

SimpliSafe Carbon Monoxide Detector battery will last up to 3-5 years. If the alarm battery is low, the alarm may just vibrate. So far, that hasn’t happened. The alarm will turn on when it detects CO and the carbon monoxide alarm will sound for 15 seconds. It can send a text message to your phone and it will play a recorded beeping noise until the CO level is low enough to take action. The alarm will reset after one hour.

Carbon Monoxide is the leading cause of accidental poisoning deaths, especially among senior citizens. This device uses infrared detection to indicate the presence of carbon monoxide gas and possible health problems, including heart failure, respiratory failure, and paralysis.

The SimpliSafe Carbon Monoxide detector we received was a return, but we are grateful for the gift. It’s smaller than other detectors we’ve had, but still provides effective alerts. The glow of the light is also enough for us to know it is on and working, but not enough to give us the true idea of the level of danger in the room.

I still have it placed throughout the house for immediate alerts. I was surprised to find the detector does not require a line of sight for operation. With many other detectors, the alarm unit has to be within 6 feet of the detector. However, the SimpliSafe detector has a wall-mountable case.
