  • HVAC Expert Andy Fox Shares Essential Filter Replacement Tips
    Andy advises replacing 1” filters every three months and 4-5” filters every 6-12 months. "Dust, dander, and smoke can clog filters," he warns, risking system damage. Use distilled water in humidifiers to prevent mineral buildup. Consider longer-lived filters and use apps or seasonal changes as reminders. Immediate replacement is needed if the system struggles or airflow decreases.
