Most manufacturers recommend changing the filter at least once a year or every 12,000 to 15,000 miles, but this can vary based on driving conditions. Regular replacement ensures optimal airflow and filter performance, keeping the cabin air clean.
• Brand Reputation: Opt for filters from reputable brands known for their quality and performance. Researching customer reviews and product ratings can provide insights into the effectiveness of a specific filter. Well-established brands often invest in research and development to produce filters that meet or exceed industry standards.
