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

Comfortable and effective face masks from CellBlock FCS.

The CellBlock/NANO+ Comfort Mask has become the gold standard in a reusable mask. It utilizes a thin layer of nano fabric that has been treated with an antimicrobial exterior coating, which kills germs on contact and provides water resistance. The NANO+ features three layers with each providing optimal benefit:

  • Outer Layer: double-coated with nanoparticulates to safely neutralize 99.5% of bacteria; water resistant, yet breathable
  • Filter Layer: 3.5oz poly filter layer provides additional filtration
  • Inner Layer: soft cotton for comfort against the face
  • Bendable nose piece and well-formed design provides a respirator-quality fit.
  • Hand washable up to 30 washes = great cost savings over disposable masks
  • Trusted supplier — CellBlock manufactures 100% of its masks in North America
  • 85% filtration efficiency (0.3 micron particle)
  • Available in 4 styles and 2 sizes
  • Exceeds CDC guidelines

The CellBlock/NANO1 was also been recently developed to meet the demand for lighter weight masks. It utilizes a thin layer of nano fabric that has been treated with an antimicrobial exterior coating, which kills germs on contact and provides a degree of water resistance.
