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. Available in two sizes as well as with optional adjustable straps. They have been particle tested alongside surgical masks and N95 masks and have performed well.

• Available with standard or adjustable cords, or ear loops
• 89% filtration efficiency (0.3 micron particle)

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
• May be branded with your company or organization’s logo

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. The NANO1 integrates the nano textile between two layers of woven fabric for optimal longevity of the mask.

• Three layers: Lightweight inner Nano fabric integrated with two layers of woven fabric, very breathable
• Antimicrobial treatment kills germs on contact
• 75% filtration efficiency (0.3 micron particle)
• Bendable nose piece; respirator quality fit
• Water resistant
• Available in 2 sizes
• Available with standard or adjustable cords, or ear loops
• Hand washable up to 30 washes

Similar to the NANO1, the CellBlock/NANO2 is a lightweight mask. It is an economical option that relies on just two layers: the antimicrobial and water resistant nano textile on the outside; and a woven inner lining.

• Lightweight Nano Fabric outside, woven layer inside
• Antimicrobial exterior coating kills germs on contact
• 73% filtration efficiency (0.3 micron particle)
• No nose piece; surgical mask fit
