air circulation in cars

kahit po air tight ang kotse, basta gumagana nang maayos ang air conditioning system, di magkakaroon ng CO2 build-up...

the air conditioning system traps significant amount of the carbon out of the CO2 (on the evaporator), then gives the fresh air again out of the louvers...

If you may have noticed, kahit na never kang nagbubukas ng bintana sa kotse, lakas pa rin ng dust sa loob which is actually because of the carbon out of the people's breath.... same dust that's being caught on the aircon's air filter and evaporator coil...

I hope this helps....
