Dupont Sierra Cleanroom Facemask ML7360 BH  Box 260 Masks

Sierra™ Masks for cleanroom environments increase compliance through comfort and provide an ideal balance of bacteria and particle filtration efficiency and breathability.

Some masks compromise breathability and barrier performance. Either breathability is reduced to achieve barrier or barrier is reduced for higher breathability. With Sierra™ masks you get both breathability and barrier protection for your controlled environment needs without compromising the comfort you want.


    The ideal face mask combines high breathability with exceptional filtration efficiency. Sierra™ face masks deliver both.

    • Mask is 9″ size with bound Tyvek® ties for cleanroom use
    • Pleated rayon outer facing
    • Metal nose piece
    • One size fits most

Cleanroom Face Masks

Contamination from the mouth area provides an immense risk to products manufactured in critical environments due to the high level of micro organisms and ionic contaminants in saliva. Furthermore, facial hair and skin particles are also a problem when trying to minimise pariculate counts. Face masks greatly reduce harmful contaminant levels and CES offer a choice of face mask styles which offer a range of benefits.
