Strengthen Your Mask
- Effective as Surgical-Grade N95

Airborne viruses such as SARS-CoV-2 are primarily transmitted through respiratory droplets. N95 respirators block the transmission of 95% of these droplets while fabric face masks typically block 40%-60%. In a study by Northeastern University, applying Garment Shield™ to fabric face masks significantly increases their effectiveness.
