Weather changes tend to trigger allergies, for a variety of reasons. For example, high winds result in an increase in the carrying and distribution of various pollens and moulds that can trigger allergic reactions; rain can increase the amount of mould spores; and a sudden spike in summer heat can dry out or irritate nasal passages, also triggering allergic reactions and asthma attacks. This can lead to dangerous situations while driving, since a sneezing driver is a blind driver. That’s why people suffering from pollen allergy should keep the windows closed while driving. To prevent the allergenic pollen to get into the car through the ventilation or air-conditioning systems, most cars are nowadays equipped with a cabin filter. In an effective manner it keeps pollen, dust and even pollution out of the passenger compartment. Nevertheless – just as with any filter – the effect of the cabin filter also decreases once the filter capacity is exhausted.

“Annual On-Time Filter Replacement Prior to Pollen Season Provides Protection”

In order to achieve an optimum filter effect during the critical pollen season, the cabin filter should be replaced once a year, Bosch filter experts recommend, too. In this context exchanging the standard filter by an activated-carbon filter is well worth it. Its activated carbon layer – made out of coconut shells absorbs gaseous pollution thanks to its spongy structure. In addition to pollen and fine particulates, Bosch activated-car- bon cabin filters even retain stinking and harmful gases such as ozone or nitric oxide. Any workshop can quickly and easily replace the filter or the standard filter by an activated-carbon filter.
