What indicators should be considered when choosing lights for sterile rooms?

Choosing a cleanroom light is not just about choosing a high-brightness type, but also about meeting strict requirements for dustproof, anti-static and cleanability. A substandard lighting system can cause an uncontrolled environment, cross-contamination and violate GMP, ISO 14644 standards.

Causes of moldy HEPA filters in clean rooms

The reason why HEPA filters get moldy is not only due to humid environments or improper maintenance, but also due to substandard HVAC system design. When the “lungs” of a clean room are attacked by mold, not only does the filtration efficiency decrease, but it also directly threatens the sterility of the entire production area.

Installing Pass Box in wrong position: Risk of cross-infection

Installing the Pass Box in the wrong position is a common mistake in cleanroom design, causing a serious risk of cross-contamination between areas. When the air flow direction, pressure difference and proper arrangement of clean-dirty areas are not followed, the Pass Box loses its isolation effect, directly affecting production quality.
