Most modern cars come equipped with two air filters: an engine air filter and a cabin air filter.
Engine air filters are designed to filter dirt particles, bugs, and other contaminants from the outside air as it passes into the engine’s intake manifold, where oxygen from the filtered air mixes with fuel to power the vehicle through a combustion process. Naturally, engine air filters lose effectiveness over time as they collect contaminants from the air, thus requiring regular replacement. Failure to replace an engine air filter that has reached is the end of its life can result in poor engine performance and decreased fuel efficiency.
Cabin air filters, on the other hand, are designed to filter dust, pollen, and other allergens from air passing through the heating and air conditioning system into the interior of the vehicle. Like engine air filters, cabin air filters also lose effectiveness over time and require regular replacement. Regularly changing your cabin air filter ensures that the air you breathe is clean and free of odors, increases the longevity of your vehicle’s heating and air conditioning systems, and promotes safety and improved visibility when driving.
At Wilton Auto and Tire Center, we recommend having both the engine air filter and cabin air filter changed either once a year or every 12,000 miles, whichever comes first. It is important to note that environment also plays a role in determining the life span of your air filters. For example, if you regularly travel on dirt or other unpaved roads, your air filters will be exposed to more dust and debris than if you drive primarily on paved roads, thus requiring more frequent replacements. By scheduling your vehicle for service and preventative maintenance at regular intervals, you allow your auto repair technician the opportunity to inspect your engine and cabin air filters regularly and provide recommendations on when your air filters should be changed based on you and your vehicle’s particular needs.
