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.

- Store personal items
