We developed our CellBlock/TT1 mask to standout from the crowd and offer the best protection possible in a hand-sewn mask. The design features a tri-layer construction and includes an inner non-woven filter material. The bendable nose piece and well-formed design provides a respirator-type fit.

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

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.

• Three layers: Lightweight inner Nano fabric integrated with two layers of woven fabric, very breathable
• Antimicrobial treatment kills germs on contact
