Best Carbon Monoxide Alarm

A carbon monoxide detector is a must have in any household. They provide heightened security and protect your loved one from the dangers of any gas leaks.

Among the top five detectors mentioned above the best detector, in our opinion, is the Nest Protect (2nd gen). I’m quite fond of the whole Nest line of devices. I love the advanced use of technology paired with everyday household items.

To me, and I believe to anyone, it’s incredible to have alerts sent straight to your phone especially to the hearing impaired. It has a vibrant LED screen and is wired for a longer use. Not to mention, it has built-in backup batteries in case of a power outage for more durable protection.

Although it may be pricier than most carbon monoxide detectors, it is well worth the money. As a matter of fact, the only cons of this device is that it may be more difficult to set up with older people and it costs a little bit more than a standard device.

I would highly suggest this Nest Protect device to people who are more familiar with technology such as smartphone and tablets. I also suggest that if you plan on purchasing this device to do your research in making sure it properly suits your home since it needs to be wired in.
