Garment Shield™ Premium Stain Repellent

In a study by Northeastern University, applying Garment Shield™ to fabric face masks significantly increases their effectiveness, and produced filtration efficiency equivalent to that of a surgical-grade N95 respirator.

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%.

Garment Shield can be used on Cotton, Wool, Polyester, Denim, and Spandex. Not recommended for use on Silk.

Yes, fabrics can be laundered as normal.

These are cancer causing chemicals in which you should keep away from your skin. We do not recommend using these types of chemicals.

Garment Shield repels against liquid spills or stains. Garment Shield is not intended to fully repel grease or oil-based stains.

If properly applied, Garment Shield can last up to six months. We recommend reapplying Garment Shield after every 1-3 wash cycles for maximum repellency.

Short Answer: Because Garment Shield does not have fluorochemicals in the chemistry. Most other "clear" sprays contain these dangerous PFAS.
