contamination control

There has been an increase in diseases caused by airborne infections such as influenza A/H1N1 or SARS in the recent years. Airborne infection isolation rooms are commonly used to limit the spread of airborne infections. The challenge today is that there is only a limited number of airborne infection isolation rooms in each hospital (class P4). The rooms are expensive to build and airflow control to avoid contamination is often complicated.

The particle-free conditions provided by cleanrooms are vital for much of modern manufacturingindustry. There has been a substantial increase in the working environment of cleanroom. Specialgarments are therefore dressed in all cleanrooms to control particles and microbiological contaminationdispersed from personnel in cleanrooms. However, more tightly-woven fabrics of cleanroom garmentswill result in thermal comfort dissatisfaction. In this study, field tests of a cleanroom have been carriedout in our newly constructed MEMS laboratory.
