The Purolator PBC36174 Premium Cabin Air Filter is engineered to enhance the air quality within vehicle cabins by providing advanced filtration capabilities. Designed with a triple-layer protection system, this filter effectively blocks and controls odors, filters out fine dust particles, and prevents the growth of mold and bacteria on the filter itself. Its dimensions of 9.76 inches in length, 7.95 inches in width, and 1.38 inches in height make it suitable for a variety of vehicles, including popular models from Ford and Lincoln. The filter's construction includes a particulate layer that captures up to 99% of fine particles such as road dirt, brake dust, soot, pollen, and other inert allergens, thereby improving HVAC and defroster performance. Additionally, the filter incorporates Febreze Freshness technology, offering an unscented solution for fresh, clean air without introducing additional fragrances. For optimal performance, it is recommended to replace the cabin air filter every 12 months or 12,000 miles, or more frequently in harsh or dusty environments. This maintenance ensures the continued effectiveness of the filter in providing cleaner, fresher air for vehicle occupants.
