Air filters are devices which use fibrous materials to remove solid contaminates from the air, such as mold, pollen, bacteria, and dust. Vehicles use two different types of air filters: automotive cabin air filters and internal combustion air filters.
Cabin Air Filter
The cabin air filter cleans pollen, dust, and other contaminates from the climate control air flow (air conditioning and heating). If working properly, the filter makes sure that the air circulating inside the car is free from the harmful elements. If these filters are not replaced periodically, AC performance can be negatively affected. In extreme cases, a clogged filter can even pose a potential health risk for the driver and any passengers. It's recommended that the cabin air filter be changed every 12,000 miles, or at least once a year, whichever comes first. The internal combustion air filter prevents contaminates from entering an engine's cylinders, which could cause extra mechanical wear as well as contaminating the engine's oil. If the air flowing though the engine isn't adequately filtered, the effects can lead to excessive fuel consumption and low engine power, eventually requiring expensive repairs.
Internal Combustion Filter
Are you one of the many drivers who neglect’s to change their car’s air filter on a regular basis? With the purchase of a new car, your sales person will normally include a maintenance schedule of things to have completed such as oil changes, tire rotations, battery checks and other standard items while your car is under warranty. Amid respiratory concerns about outdoor air pollution, a vehicle’s air filter functions similarly to your lungs. A clogged air filter comes from gradual buildup of dirt and debris. It is recommended that you change your air filter every 12,000 to 15,000 miles.
