The pollen count is at its peak every spring and spending time both outside and inside vehicles is particularly problematic for allergy sufferers. Cabin air filters, which are generally standard, are designed to filter exhaust gases and other air pollutants. If the cabin air filter can no longer fulfill its function, more air pollutants such as dust, soot, nitrogen oxides, benzene, ozone or pollen can enter the interior of the car, for example via the air conditioning system.
