January, February, and December are the most dangerous months for carbon monoxide illnesses and deaths (according to the CDC). Carbon monoxide is an odorless, colorless, and poisonous gas that often strikes with minimal warning signs and may be produced by malfunctioning equipment such as furnaces, water heaters, clothes dryers, generators, wood burning stoves, and more.
Carbon monoxide monitors are an extremely useful defense mechanism used to alert homeowners to carbon monoxide exposure. However, not all CO monitors are the same. Some CO monitors are not low-level detectors. This means that some types of detectors may not sound a warning alarm until 70 parts per million or more. These levels are already dangerous for the very young, old, or ill.
Please consider a low-level carbon monoxide monitor such as the NSI 3000 which monitors and displays levels as low as 5 parts per million and alarms as low as 15 parts per million.
The EPA states that 9 parts per million is the maximum allowable CO level over an 8-hour period. The World Health Organization states that 15 to 30 parts per million is the level at which harmful effects may begin to appear.
