Have you heard the point about air fresherners being bad for your car's system as the chemicals being sucked in by the air intake is corroding the metal pieces in the car's air con. Have you ever noticed when the air fresherners spill on any plastic, it stains and eats into the material. So my point is - imagine inhaling this smell/chemical into you lungs ????

That's why I started using air ionizers instead, both no smell and good for driver and passengers. Go look into the thread on Neo Tec air ionizers in this forum on cars. Cheers
