Additionally, consider attending industry trade shows and conferences for networking opportunities.
Request quotes and compare features to find a supplier that meets your specific needs.

How is an ISO 8 cleanroom classified?

An ISO 8 cleanroom is classified based on its maximum allowable particle concentration. Specifically, it must not exceed:

• 3,520 particles per cubic meter for 0.5 µm size
• 29 particles per cubic meter for 5 µm size
  This classification ensures that the cleanroom meets necessary cleanliness standards for specific applications.

How often should cleanroom filters be replaced?

Cleanroom filters should typically be replaced every 6 to 12 months.
However, this frequency may vary based on usage and environmental conditions.
Regular monitoring of filter performance is essential for maintaining optimal air quality and compliance.

How can I enhance the safety of cleanroom operations?
