Considerations for ISO class 8 cleanrooms

High Efficiency Particulate Air (HEPA) Filtration is 99.99% efficient at 0.3 micron and should be considered when looking to achieve ISO class 8.

Monobloc panel, hardwall and softwall cleanroom envelopes are all effective at achieving the environment required for ISO class 8.

If organisations are working towards GMP grades, monobloc is the most effective solution, as it can accommodate required features such as interlocked doors and coved floors.
