The main purpose of the cabin filter is to protect against the polluted air (dust, soot, flue gas, bacteria, pollen, etc) that we breathe inside our cars without even being aware of it. These micro particles cause an increase in allergies and other respiratory diseases, thus UFI Filters recommends regular replacement of the filter element in order to ensure the wellbeing and health of the vehicle’s occupants.
Replacement is recommended in order to maintain the high performance of the filter. When the filter start clogging it looses its filtration efficiency and looses pressure drop.
Direct consequences of a bad air quality in the cabin are:
- allergy, itchy throat, sneezing while driving;
- driver fatigue after a prolonged period of conduction;
- poor visibility – excessive condensation is generated on the glass.
The exact concentration of dust in the atmosphere and the proportion harmful particles depends on variable factors such as the weather conditions and the geographical area. While such factors are rather changeable, it is estimated that there is an average of between 10 to 80 billion suspended particles per cubic meter (m³) of air that we breathe. In spring, and particularly after a rainy winter, this figure increases due to the increase in pollen.
Due to the “tunnel effect”, the concentration of particles so harmful for our health may get six times higher inside our car.
“Tunnel effect”: exhaust gases present in the air and those of the vehicle in front get into the passenger compartment, due to the low filtration efficiency of the filter or to a clogged filter.
