The Purolator PBC45871 BOSS Premium Cabin Air Filter with Febreze Freshness is engineered to enhance the air quality within Nissan Altima and Murano vehicles. This filter employs a triple-layer protection system that effectively captures up to 99% of airborne contaminants, including pollen, dirt, soot, and other fine dust particles. The integration of Febreze Freshness technology not only neutralizes odors but also imparts a subtle, clean scent to the cabin environment. An antimicrobial layer within the filter prevents the growth of mold and bacteria, ensuring a healthier atmosphere for occupants. Designed to maintain optimal airflow, this filter supports the efficient operation of the vehicle's HVAC system, contributing to improved defroster performance and overall comfort. For optimal results, it is recommended to replace the cabin air filter annually or more frequently in harsh or dusty environments. This filter meets or exceeds original equipment (OE) performance requirements, providing a reliable solution for maintaining a clean and fresh cabin environment in Nissan Altima and Murano models.
