How to Replace the Cabin Air Filter in a Mercury Marinerby David Clair
Every model year of the Mercury Mariner is equipped with a cabin air filter. The purpose of the cabin air filter in the Mariner is to prevent dust and allergens from entering the car's ventilation system where it could reach the passenger cabin. Mercury recommends replacing the cabin filter every 10,000 miles, or every 12 months. If the Mariner is frequently driven on dirt roads or in heavy traffic conditions, the filter will get dirty faster. A clean cabin air filter increases air flow throughout the air conditioning system and keeps the air in the passenger area clean.
