Introduction
In pathological laboratories, maintaining a sterile and contamination-free environment is critical. One essential component of achieving this is the Mist Shower (雾淋室), a specialized purification system designed to minimize particulate contamination. This article explores its function, differences from air showers, validation methods, and compliance standards.

一、What Is a Mist Shower (雾淋室)?

A Mist Shower is a controlled decontamination chamber that uses a fine mist of disinfectant or sterile water to remove contaminants from personnel or equipment before entering cleanroom environments. Unlike traditional air showers, it combines liquid and air purification for higher efficacy in sensitive settings like病理 laboratories.

二、Key Functions of Mist Showers

  1. Decontamination
  2. Humidity Control
  3. User Safety

三、Mist Shower vs. Air Shower (风淋室): Key Differences

Feature
Mist Shower
Air Shower
Medium
Disinfectant mist + air
High-velocity HEPA-filtered air
Effectiveness
Higher for sticky contaminants
Better for dry particulates
Applications
High-risk病理 labs, BSL-3/4
Electronics, general cleanrooms

四、How to Validate Mist Shower Purification Efficiency?

  1. Particle Count Tests
  2. Microbial Sampling
  3. Airflow Visualization
  4. Compliance ChecksISO 14644-1GMP Class B/C

五、雾淋室 Meaning and Standards Compliance

“雾淋室” translates to “mist shower room,” emphasizing its liquid-based purification. Its workflow must adhere to:
  • ISO 14644
  • WHO GMP
  • OSHA 29 CFR 1910.1450

六、Mist Shower Workflow Steps

  1. Entry
  2. Mist Cycle
  3. Drying
  4. Exit
Conclusion
Mist showers offer superior decontamination for病理 laboratories, combining liquid and air purification. By adhering to international standards and rigorous validation, they ensure both safety and regulatory compliance.
