SHEMA97 face mask assessment

2/1/21: Looking into the effectiveness of this popular face mask seen on TV with sports figures.

Wrong Approach: This is the text accompanying this good looking mask. Maybe good for dust, but not liquid droplets.

“HelmetFitting.com’s SHEMA97 Functional Active Mask uses nano fabric technology to protect the respiratory system from harmful substances and infectious sources. The micro dust proof fabric helps prevent the inhalation of airborne dust and potential virus-laden particles with a 97.1% fine dust filter rate. Its special purpose fabric filters particles down to one micron for superior protection.

Error: The virus is not dust. It is not a dry substance. It does not travel alone. It travels in water droplet which easily goes through this mask.

Proof it for yourself. Put the mask on and place a mirror in front of the mask. Cough. You will see the moisture on the surface of the mirror.

Then put some tap water on the outside of the mask and inhale with your mouth open. You will sense the water come into your mouth.

Good for dust. Not likely good for virus.
