CellBlock Fire-Rated Comfort Masks

CellBlock Comfort Masks

CellBlock FCS designed these reusable face masks to address the persistent shortage of supplies for health care workers, first responders, and essential personnel during the COVID-19 pandemic.

Our Comfort Masks offering has continued to expand. These high-quality masks are now available in four sizes, three styles and numerous capabilities to accommodate the emerging needs of businesses and individuals. Our original TT1 mask is still the best with the highest particulate efficiency and a respirator-quality fit. However, many people have difficulty tolerating a layered mask, especially during the hot summer months. CellBlock has developed a wider array of thoughtfully designed and effective masks to address this concern.

  • Choose from three filter weights
  • Antimicrobial options increase effectiveness by killing germs on contact without sacrificing breathability
  • Lightweight options allow compliance in lower-risk situations where a filtered mask is not required
