Driving around the neighborhood or cruising on the freeway would be better if your air inside the car is purified. Sure, there’s the automotive air conditioning but it really doesn’t help a lot in purifying the air within the cabin.
Not all pollen, dirt, allergens and what not are captured by your car’s air conditioning unit. This is why the extra step I’m talking about is crucial especially for those who are suffering from allergies and asthma. It never hurts to add a layer of extra protection, prevention is way better than cure.
