The Cabin Air Filter serves as a safeguard between exterior airborne contaminants and your INFINITI’s cabin. Thanks to its anti-bacterial and anti-odor features, authentic INFINITI HVAC Cabin Air Filters keep common pollutants like mold spores, ragweed particles, construction dust, and dander from sneaking in through your INFINITI’s heating and air conditioning system. In addition, genuine INFINITI Cabin Air Filters help inhibit small bugs and crumbled leaves from getting into your vehicle’s HVAC, impeding them from affecting your heater and air conditioner’s performance.

With time and mileage, your INFINITI’s Cabin Air Filter may get congested or worn, especially if you drive in areas poor air quality or high concentrations of allergens. Most INFINITI cars can benefit from HVAC Cabin Air Filter changes every 15,000-30,000 miles. However, one of the top ways to determine when you should get a new Cabin Air Filter for your Cabin Air Filter is by referring to the owner's manual or looking out for common signs that your current HVAC Cabin Air Filter is not doing its job efficiently. You may suspect your Cabin Air Filter is not working optimally if you notice musty odors coming from you car’s A/C vents when the A/C or heater is on. Additionally, if your INFINITI’s fan is on “high,” and the airflow is weak or non-existent, a dirty Cabin Air Filter may also be to blame. Finally, though odd sounds and a loud HVAC system are unusual with Cabin Air Filter issues, they do occur in some cases! If those in the passenger compartment notice any of these signs and your vehicle is running as usual, consider getting a replacement INFINITI Cabin Air Filter to clear the air.

Replacing a Cabin Air Filter is a service that many drivers choose to do at home or with their local INFINITI experts. If you decide to DIY a Cabin Air Filter replacement, make sure to check the owner’s manual for help locating the filter (though Cabin Air Filters are typically behind the glovebox). In the majority of cases, a screwdriver, rag, and vacuum will be essential tools for replacing your Cabin Air Filter. Yet you should follow the directions in your INFINITI’s manual to ensure you change your Cabin Air Filter correctly.
