The Odourless Invisible Killer
Most carbon monoxide sensors that are designed for residential applications (that is also being suggested by Zerorez) are not very accurate in that its tolerances are larger than they should be and their sampling time intervals are too wide. Most CO detectors only start detecting levels above 30 ppm. Today the UCLA Medical Center, EPA, ASHRAE and Health Canada all agree that breathing air containing over 10 ppm of CO is very unhealthy air.
Common brand of Carbon Monoxide detectors include First Alert or Kiddie which, for most of their models, has a sampling time of up to 15 minutes when the sensor is exposed to 400 ppm. At these levels, CO can cause death within hours and may render the occupants unconscious and not likely to respond to any alarms. Personally, I would not be purchasing these brands.

With most detector units, they only start detecting levels above 30 ppm. Some of the CO monitoring units, that do cost more, can detect and show digitally show the actual readings as low as 5 ppm. This is a smarter option as it provides protection to chronic CO exposure especially pregnant woman, infants, elderly people, young children or have a health condition such as heart condition or respiratory trouble.

Standards Used by Most CO Detectors
There are requirements for CO detectors for follow set by Underwriters Laboratories and Canadian Standards Association or UL/CSA.
0-29 ppm No audible or visual alarm. Displays 0.
30-69 ppm No audible alarm, Displays only ambient CO level.
70-149 ppm Alarm sounds in up to 4 hours.
150-399 ppm Alarm sounds in up to 50 minutes.
400 ppm+ Alarm sounds in up to 15 minutes.
400 ppm is enough to kill a person yet the associations that govern the rules for manufactures state that 399 ppm can take up to 50 minutes for the detector to sound even a warning. When you take the time to actually understand this and the ramifications this has to ones life, you can make smarter decisions. Choose a low level monitoring device rather than a detection device.
What is even more alarming is the length of time that new units may take to start alarming being up to 30 days. What this actually means is, a newly installed CO detector, even exposed to deadly levels of Carbon Monoxide, may not start beeping immediately. Immediately is defined as within a 30 day period.
The last comment about CO detectors to consider is that they do not provide any type of reliable or useful information. One really has no idea if they are beeping due to a lack of power, calibration, sensor or unit failure, what the true levels are and what to do. A low level monitor is a smarter choice.
