For sterile compounding, what is the required air quality?

  1. ISO 5 or better

  2. ISO 7 or better

  3. ISO 9

  4. There is no specific requirement

The correct answer is: ISO 5 or better

The required air quality for sterile compounding is ISO 5 or better. This means that the air should have no more than 3,520 particles per cubic meter that are larger than 0.5 microns. Option B is incorrect because ISO 7 allows for 352,000 particles per cubic meter which is significantly higher than ISO 5. Option C is also incorrect because ISO 9 allows for even more particles, 35.2 million per cubic meter. Option D is incorrect because there is indeed a specific requirement for air quality in sterile compounding, and it is ISO 5 or better.
