Keep clean rooms free from contaminants—these coveralls act as a full-body barrier between you and the room to keep dust, microbes, and other pollutants at bay. They’re suitable for use in clean rooms rated to both Federal Standard and ISO classes. In both systems, clean rooms with lower class ratings have fewer contaminants. Reusable when washed according to clean room standards, these coveralls can last up to 100 washes. Wash them according to clean room standards before you wear them the first time.
