The Purolator PBC25870 Cabin Air Filter with Febreze Freshness is engineered to enhance the air quality within vehicle cabins by effectively capturing airborne contaminants. This filter features a triple-layer protection system comprising a particulate layer, activated charcoal layer, and an antimicrobial layer. The particulate layer blocks up to 99% of fine particles such as road dirt, brake dust, soot, pollen, and other inert allergens, preventing them from entering the vehicle's cabin. The activated charcoal layer absorbs odors and gases, while the antimicrobial layer inhibits the growth of bacteria and mold on the filter, ensuring cleaner air circulation. Unlike HEPA filters, the Purolator BOSS filter maintains optimal airflow through the HVAC system, thereby supporting the performance of the air conditioning, heating, and defroster systems. This design ensures that the filter does not impede airflow, which is crucial for maintaining the efficiency of the vehicle's climate control systems. The filter is unscented, providing fresh, clean air without introducing additional fragrances. It is recommended to replace the cabin air filter every 12 months or 12,000 miles, or more frequently in harsh or dusty environments, to maintain optimal performance. The Purolator PBC25870 is compatible with a wide range of vehicles, including popular domestic and import models, making it a versatile choice for fleet operators seeking to improve cabin air quality across various vehicle types.
