Cleanrooms are 10,000 times cleaner than a hospital operating room. It takes an incredible amount of technology to achieve and maintain such cleanliness. Huge air filtration systems completely change the air in cleanrooms about 10 times per minute, reducing the changes that there are airborne particles that might harm the product. Keeping the environment clean, however, is only half of the story.What about the people who work in the cleanrooms? The thousands of people who all wear “bunny suits” to protect products from from human particles such as skin flakes or hairs. A bunny suit is made of unique, non-linting, anti-static fabric and is worn over street clothes. Suiting up is a rather involved process, not to mention that every time you enter and leave a cleanroom you have to repeat the steps below:

Store personal items

  1. Discard any gum, candy, ect.
  2. Remove any makeup with cleanroom soap and water

Now not all cleanrooms will follow this exact regimen, but it does give you an idea of what is involved for employees entering a cleanroom. Each step gets the user “cleaner” without contaminating the next layer.

When leaving a cleanroom these steps are taken in opposite order and each layer is disposed of properly. Suits, helmets, and goggles can be cleaned and reused or disposed of. Gloves are almost always one time use items, same with hairnets, bouffants, beard covers, and shoe covers; all are one time use items.
