OLD POLLEN FILTER VS NEW
A pure example of why you should have your cars pollen filter changed while servicing your car once a year.
Not only is it bad for your car to have a dirty pollen filter but it is also bad for your health. The cabin air filter helps trap pollen, bacteria, dust and exhaust gases that may find their way into a vehicle’s air conditioning and heating and ventilation systems. The filter also prevents leaves, bugs and other debris from entering the heating, ventilating and air-conditioning (HVAC) system. Particulate and exhaust fumes such as fine dust, diesel soot, pollen bacteria and nitrogen oxides enter the vehicle through the vents and concentrations of these toxic substances inside can be higher than at the side of the road in urban traffic conditions. A dirty or clogged cabin air filter can cause musty odors in the vehicle and cause contaminants to become so concentrated in the cabin that passengers actually breathe in more fumes and particles when riding in the car compared to walking down the street. A restricted cabin air filter can also impair airflow in the HVAC system, possibly causing interior heating and cooling problems, important for staying comfortable this winter. Over time, the heater and air conditioner may also become damaged by corrosion.
