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. The mask design features a tri-layer construction and includes an inner non-woven filter material. 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.
While the CellBlock|TT1 mask are considered to be disposable, they may be cleaned several times for repeat use. This makes them an economical choice.
