Designed to meet clean room standards, these coveralls act as a barrier between the worker and the room to prevent pollutants, such as dust particles and microbes, from contaminating a space. 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. They provide full body coverage and have a zipper down the front.

Tyvek polyethylene is made of heat- and pressure-bonded fibers for a material that’s soft yet strong. It holds up to occasional contact with nonhazardous liquids, such as water and paint spray. These coveralls are disposable. They have elastic cuffs to help keep liquids from splashing in.

Polyester greatly outlasts Tyvek polyethylene. It resists abrasion and liquid splashes and is reusable when laundered to clean room standards—lasts for up to 100 washes. Must be laundered prior to first use. These coveralls have knit cuffs to keep sleeves in place and prevent liquids from splashing in, as well as snaps on the collar and snaps on the pant cuffs to modify the fit.
