Pollen Filters(A/C Air Filters)
pollen filters means a filter that cleans air coming into the car. a different function. When people refer to pollen filters they normally mean a filter that cleans air coming into the car. Cabin filters on the other hand are taken to mean filters that treat the incoming air and the recirculated air. In this website we refer to both terms in a generic sense, and any reference to one, means both types. Cars will generally have either a pollen filter or a cabin filter, rather than both.
echnically pollen air filters are quite straightforward. Many originals ones used heat bonded non-woven synthetic fibres and were cased in moulded plastic frames. The media was usually pleated in order to maximise the area of media available to the airflow, which prolongs pollen filter performance and its life.
Most modern pollen filters have dispensed with the plastic frame and use instead a 'melt blown' synthetic card frame, and melt blown synthetic media. These type of filters rely much more on the filter housing when installed, for their structural integrity, compared to the old plastic framed variants, which were very strong in their own right.
