Mist Shower and Air Shower in Cleanrooms

In controlled environments such as cleanrooms, the entry of airborne particles and microbes can pose serious risks. To prevent contamination, Air Shower and Mist Shower systems are used.

Mist Shower

A Mist Shower uses fine water mist or disinfectant solution to clean the surfaces of clothing and equipment, removing both particles and microbial contaminants.

How it works:

  • Personnel enter the chamber and the door closes.
  • Nozzles spray a fine mist of water or disinfectant over clothing and equipment.
  • Particles and microbes are washed away and captured by the filtration system.
  • The process usually takes a few seconds up to one minute.

Benefits:

  • Thorough cleaning of particles and microbes from surfaces
  • Reduces microbial contamination risks
  • Can be used in combination with an Air Shower for comprehensive decontamination

Air Shower

An Air Shower is a small chamber placed between the external environment and the cleanroom. It uses HEPA- or ULPA-filtered high-velocity air to remove particles from personnel and equipment.

How it works:

  • Personnel enter the chamber and the door closes.
  • Nozzles on the walls blow high-speed, filtered air over clothing and bodies.
  • Dust, hair, and other particles are removed from surfaces.
  • The process typically lasts 20 to 60 seconds.

Benefits:

  • Reduces particle contamination entering the cleanroom
  • Enhances safety of products and environment
  • Helps maintain ISO and GMP standards
