How often should the laminar air flow hood be certified?

• A. Daily
• B. Weekly
• C. Every 6 months
• D. Annually

Answer: (C)

Regular verification of a laminar air flow hood is needed to ensure it continues delivering clean, sterile air and protecting the compounded products from contamination. Over time, airflow can drift and the HEPA filter can lose efficiency; room conditions, movement, or recent maintenance can affect performance. Because of these factors, a formal certification is performed every six months. This semiannual timing helps catch drift early while fitting practical maintenance schedules. Certifications are done by qualified personnel using proper testing methods to confirm airflow patterns, filter integrity, and containment. Daily or weekly checks are useful for spotting obvious problems, but they do not replace the formal certification. Waiting until annually could allow performance changes to go unnoticed.
