FAQs About Cleanroom Design

Q: Are There Any Standard Cleanroom Design Requirements?


  • HEPA filtration air flow per ISO 14644-1 / US FED STD 209E cleanroom standards
  • Low velocity vertical laminar HEPA filtered air flows to maximize cleanroom effectiveness and efficiency (see cleanroom air flow diagram)
  • Low all air returns to create vertical ceiling to floor HEPA filtered air flow – sweeping particulates down to floor level then out of cleanroom
  • Positive air pressure vs. outside cleanroom to prevent contamination from entering cleanroom.
  • Magnehelic gauges to monitor and measure room pressure
  • Cleanroom classified gowning room so workers can put on cleanroom smock, booties, and hoods to reduce particulates in cleanroom
  • Cleanroom classified material transfer room or interlocked pass thru to avoid introducing particulates into the cleanroom when bringing material in or out.
  • Cleanroom heat welded vinyl or epoxy flooring to ensure flooring is not source of particulates
  • Cleanroom vinyl coated ceiling tiles to ensure ceiling is not source of particulates
  • Cleanroom sealed ceiling lighting to ensure ceiling is not source of particulates
Q: What is a Pharmaceutical Cleanroom?

A: Pharmaceutical manufacturers are subject to FDA validation of their manufacturing which typically specify use of a clean room to ensure the quality of the manufactured pharmaceutical product. Sterility is highest priority. Pharmaceutical cleanrooms focus on both non viable (inanimate) and viable (live) contamination. They typically use laser particle counters to measure non viable contamination levels and settling plates with culture media to measure viable contamination levels. Pharmaceutical cleanrooms use aggressive chemical and UV light cleaning techniques to maintain sterility.

Q: What is The Purpose of a Cleanroom?

A: Cleanrooms are used in any industry that wants to control contamination in their facility. It is common to see pharmaceutical cleanrooms, medical device cleanrooms, semiconductor cleanrooms, electronic cleanrooms, aerospace cleanrooms, food cleanrooms, USP797 compounding pharmacy cleanrooms and biotech cleanrooms. Cleanrooms are also used by the government such as national labs, defense industries, and R&D labs at universities.

Q: What Are Cleanroom Requirements?

A: Most common cleanroom requirements include cleanroom classification, size, number of rooms, cleanroom flooring, cleanroom ceiling height, cleanroom chemical resistance, and cleanroom temperature and humidity.
