Does recirculated air go through cabin air filter?
With the ventilation system in recirculation mode, most of the cabin air recirculates, and a small (but unquantified) amount of outside air enters the cabin through natural infiltration. The Saab 93 is typical of many commercial vehicles in that recirculated air does not pass repeatedly through the cabin air filter.
Where is the recirculation setting on a cabin air filter?
It seems counter-intuitive to send inside air back over all the garbage in the filter. Cabin air filters will usually filter the air on either setting if located on the cabin side of the firewall. But even in recirculation mode, outside air will make its way in.
Is the air filter under the hood recirculated?
But even in recirculation mode, outside air will make its way in. Just be sure to replace it as frequently as your manual suggests. However, filters located under the hood at the air intake will not filter recirculated air.
Where can I find the cabin air filter?
Cabin air filters will usually filter the air on either setting if located on the cabin side of the firewall. But even in recirculation mode, outside air will make its way in.
When does air pass through the cabin air filter?
In general, does air recirculated in the cabin (i.e. when the re-circulate button is engaged on the dash) pass again through the cabin air filter? I know that the cabin air filter filters outside air before it enters the passenger space, but is it also used in closed re-circulation?
