Valutek’s Cleanroom Facemasks come in a variety of styles and offer comfort and quality. The mouth is the No. 1 particle generator on an operator, where contamination can originate in the form of skin flakes, spittle mucous, bacteria, hair follicles, residual contamination (such as smoke) and makeup. And since the head is often in very close proximity to the product, contamination from this area must be virtually eliminated. The most popular Valutek Cleanroom Facemask is the 3-ply polypropylene 7-inch face mask. It is disposable, lightweight and comfortable, comes with an adjustable aluminum nosepiece and with ear loop options of knit, covered round and tie. It is constructed of non-woven, non-linting material that is appropriate for Class 100 critical environments.
