Airflow flap

How long do you think it takes to switch from outside fresh air to recirculated?

Say, you come to traffic jam after some old diesel truck or van and you know now it will blow out a black cloud of exhaust gases. Do you want to keep air clean in your car by closing outside air hole? If you already see gases that may be late :-)

Cutting outside air - slow, 5 sec. Because actual closing the port by flap is at the end of process.

Opening - super fast, less than 1 sec.
