Cabin air filters are put there for the health of the vehicle’s occupants. The filter can trap pollen, dust, smoke and other pollutants that would otherwise enter the vehicle and possibly irritate the nose and lungs of the driver and passengers. Most of these filters are highly efficient and have electrostatically charged fibers that do an excellent job of trapping even the smallest particles (down to 0.3 microns!). A human hair, by comparison, is about 40 to 70 microns across. Most cabin air filters will stop 100 percent of all particles that are 3 microns or larger in size and 95 to 99 percent of particles in the 1 to 3 micron size range. Some cabin air filters also trap odors and are called “combination” filt... |
