Activated Charcoal Button on Climate Control....




It is not recommended to have it on all the time. Only when needed. Supposedly it will reduce airflow and heating up or cooling the interior vehicle will be effected. I also believe it will shut off after so many minutes.
I believe it is quite expensive. How do you know when it is time to replace it? When those odors keep on coming?




Does the filter "wear out"? I imagine it would lose its effectivness eventually.
There is a determined replacment interval that your service book should list.
