Best Carbon Monoxide Detector

Carbon Monoxide is a deadly gas which is colorless and odorless. In most fatal home fires, it’s carbon monoxide which kills victims long before they succumb to smoke inhalation or are burned by the fire.
 
Early symptoms of carbon monoxide poisoning are similar to the flu, making it difficult to detect by symptoms alone. These symptoms can include a dull headache, weakness, dizziness, nausea, shortness of breath, confusion, blurred vision and chest pain. Since most people are more familiar with the flu than with CO2 poisoning, they assume their symptoms are flu-related, prolonging their exposure to the gas making them sick; this can be a fatal error.
 
Unlike smoke, which is fatal if the concentration in the air is high enough, carbon monoxide usually builds up in the system over time. One can get carbon monoxide poisoning from either a low concentration of carbon monoxide over a long period of time or a high concentration over a short period of time. Therefore, carbon monoxide detectors need to determine the average level of carbon monoxide in the environment over time, determining if it is high enough to cause problems.
 
Smoke detectors don't detect carbon monoxide. If you have a smokeless fire going or a contained fire, it’s possible for carbon monoxide levels to reach fatal levels without a smoke detector going off. This could also occur with vehicle exhaust, a leaky furnace or an improperly vented hot water heater for example.
 
Ideally, you should have both carbon monoxide detectors and smoke detectors in your home. A minimum of one per floor is recommended, with additional detectors installed in bedrooms. Although this make for a lot of detectors, it provides the best protection for your family. Having a detector go off in the basement, when everyone is asleep on the second floor of the house doesn't help anyone.
 
Carbon monoxide detectors can run off of your house current, battery or a combination of the two. In the cases where a detector uses both, the battery serves as a power backup for the AC house current. That way, you’re always guaranteed a working detector, even in a power outage nor worry about the battery dying at the wrong time.
 
The best carbon monoxide detectors are now using Lithium-Ion batteries for prolonged battery life and they’ll also have a test button-like a smoke detector. Some models are now made so several units can be interconnected with one another; if one alarm goes off, it will alert and activate the others in your home.

Nest Protect Smoke Plus Carbon Monoxide Detector S2001BW

Nest has take carbon monoxide and smoke detection to a new level with a combination unit which tells you exactly what's going on, where it's going on and how much danger you're in. In addition to sounding the alarm, this interconnected detector tells you by voice what the problem is and where it’s located. It will even warn you when levels are rising, but haven’t yet reached a dangerous level. The alarm also connects to your Nest thermostat, turning off the gas to the furnace if there is an alarm and you can even monitor your home while away via smart phone. An color-change indicator for self tests, battery levels, and the low battery helps eliminate confusion.

First Alert SCO7CN-C Child Awakening Smoke and Carbon Monoxide Alarm

First Alert recognizes children can be hard to awaken, so they’ve designed this alarm to wake even the soundest sleeper. This combination smoke and carbon monoxide detector operates off of battery power and includes a voice alarm, as well as an audio alarm, to tell you where the danger is and how severe it is. The unit has been designed to use low power, so that the two AA batteries powering it will last for up to ten years. Smoke detection is accomplished via photoelectric technology and CO detection is via electrochemical sensors.

Rich the Tool Man

Before embarking on the current stage of my life, I spent 15 years as a Manufacturing Engineer in both the medical equipment field (medical electronics) and automotive engineering (city transit buses). After that, I owned a small construction company, mostly doing residential remodeling and commercial tenant finishes. I am no longer in either of these fields, but still get my hands plenty dirty as a consummate do-it-yourselfer; working on everything from remodeling my own home to rebuilding my car’s engines. My hobby (when I can find the time) is woodworking; making everything from toilet paper holders, to shelves, to music stands for my own home. My wife long ago gave up the idea that a two car garage is for parking two cars; it is my workshop.

While I cannot claim to having worked professionally with all types of tools, I have worked professionally with some. This comes from my previous careers, where I had to specify, buy and at times live with those decisions. Additionally, I would have to say that my engineering background has given me a thorough understanding of the construction of such tools. So, while I may not have used a particular type of tool personally, I have the knowledge to cut through all the advertising hype and statistics; in order to get at the truth of how well a tool will operate and last.

In my current career as a writer, I've written over 90 books. This includes my own titles and those I've written on contract. I've also written a complete website on how to build your own home.
