What does ISO clean room in filtration mean?


Firstly, what is ISO Certification?

ISO ( (International Organization for Standardization) is an independent, non-governmental, international organization that develops standards to ensure the quality, safety, and efficiency of products, services, and systems. They are set in place to ensure consistency, and to provide a global standard so that the entire world can compare things accurately and fairly.

So, what's an ISO clean room?

Cleanrooms are designed to keep out contaminants and participles. Once fully built and operational, it should be free of outside particles and contamination. The air inside a clean room is constantly "changed" every hour using HEPA fan filters.


Cleanrooms are classified based on the quantity and size of particles per cubic meters of air inside a controlled environment. The ISO standard includes cleanroom classes from 1 to 9, with ISO 1 being the "cleanest", and ISO 9 being the "dirtiest" class. However, it's important to note that the ISO 9 clean room standard is still cleaner than a regular room.


ISO 7 and ISO 8 are the most common classes for cleanrooms. Workers are required to wear face masks, hair and beard covers, sterile gloves, and lab coats when using an ISO 7 cleanroom to prevent contamination.


You'll see the term "ISO Class 7 cleanroom" on our product details for ZTEC G, TefTEC, TefTEC V, and TefTEC P cartridge filters. ISO 7 clean rooms provide air cleanliness levels of a maximum of 10,000 particles (≥0.5µm) per cubic foot and a minimum of 60 air changes per hour.
