Kimberly-Clark Professional announces its Kimtech Pure M3 Sterile Pouch Facemask, recommended for use in ISO Class 5 or higher cleanrooms. The mask’s pouch design and large breathing chamber reduces particle build-up and its tight seal helps reduce goggle fogging. Made of apertured, low-lint polyethylene film for protection against contamination, the mask contains no natural rubber latex. The masks are individually packaged, triple bagged for extra protection, and gamma irradiated with a sterility assurance level (SAL) of 10-6.
