PurolatorONE Advanced Air Filter A25042

The PurolatorONE Advanced Air Filter A25042 is designed for passenger cars and light trucks. It traps up to 99% of dirt, dust, soot and other debris to protect the engine from damage. Regular replacement helps maintain peak engine performance and efficiency.

Replaces filter at 12 months or 12,000 miles

A new filter replaces the old unit at the recommended interval of 12 months or 12,000 miles. The jump is worth it when the existing filter is clogged, as a fresh filter can improve fuel efficiency and acceleration by up to 11% according to a U.S. DOE study. Changing the filter regularly prevents engine wear.

Practical limits of paper filter media

The filter uses paper media that traps contaminants but cannot be cleaned or reused. It must be replaced once saturated or at the mileage interval. It does not address oil changes, spark plugs or other maintenance items. Buyers who need a washable or performance-oriented filter should look elsewhere.
