Maintaining your 2022 Nissan Altima's cabin air filter is crucial for ensuring clean air inside your vehicle, optimizing HVAC system performance, and protecting the health of all passengers. This comprehensive guide will walk you through everything you need to know about locating, selecting, and replacing your cabin air filter, helping you breathe easier and drive more comfortably.

Understanding the Cabin Air Filter's Role

Your 2022 Nissan Altima's cabin air filter serves as the first line of defense against airborne pollutants entering your vehicle's interior. Positioned within the HVAC system, this component traps dust, pollen, mold spores, and other contaminants before they can circulate through your ventilation system.

Recognizing when to replace your cabin air filter can prevent more significant issues down the road. Several telltale indicators suggest your filter may be clogged or dirty:

• ​Reduced airflow​ from your vents, even when the fan is set to high speed
• ​Unpleasant odors​ when you first turn on your heating or air conditioning system
• ​Increased dust accumulation​ on your vehicle's interior surfaces
• ​Poor defrosting or defogging performance​ on your windshield and windows
• ​Allergy symptoms​ such as sneezing or coughing while driving

If you notice any of these signs, it's time to inspect and likely replace your cabin air filter to restore your Altima's interior air quality and HVAC performance .

Recommended Replacement Interval

For your 2022 Nissan Altima, most manufacturers recommend replacing the cabin air filter every 12,000 to 15,000 miles or approximately once a year . However, this interval can vary based on your driving conditions.
