The major goal of Influence of Inhaler Compliance on the Treatment of Asthma Patients is to explore compliance rate outcome in adult asthmatic patients (20-80 years old) with mild to moderate persistent asthma according to American Thoracic Society (ATS) definition and diagnosis. The major endpoints include: 1. To increase the adherence rate of treatment by reminder intervention with correctly monitor patients' adherence rate by Asthma Supportive Kits 2. Eventually achieve best asthma care and management. All participants will use Asthma Supportive Kits for 24 weeks and return visit on week 5, 12, 24.
