How often must HEPA filters be recertified?

  1. Every 6 months and when a PEC has been moved

  2. Annually and when a PEC has been moved

  3. Every 12 months regardless of PEC movement

  4. Every 2 years and after major repairs

The correct answer is: Every 6 months and when a PEC has been moved

HEPA filters in a pharmacy must be recertified every 6 months and when a Primary Engineering Control (PEC) has been moved. This is crucial to ensure the filters are functioning properly and maintaining the required air quality standards in the pharmacy setting. Option A is correct because regular recertification helps guarantee the effectiveness of the HEPA filters in removing contaminants and providing a clean environment for compounding medications. Options B, C, and D are incorrect because they do not align with the recommended frequency of recertification specifically tied to PEC movement and maintaining safety standards.
