The effectiveness of facial masks still is unsettled for protection from or projection of the coronavirus. Even double masking has been explored.
My assessment is as follows: The virus is in an air born droplet; going to the mask from outside or inside the mask. The droplet stays in the mask keeping the virus viable until drying. The mask is an aqueous receptacle holding the live virus in what could be considered a “Petri dish” used for harboring and culturing microbes.
The wearer of a mask is providing a water pump moving the mask in and out with speaking or even breathing. The wearer is contributing moisture to the “Petri dish”.
A publication in Lancet showed that an COVID19 infected mask would take 6 hours after removal to dry and become non-infective.
The solution is to coat any mask with a crystal that kills the virus on contact.
See www.sprayawaydoa.com. The alcohol spray kills what is there and the residual crystalline coating kills what may be coming.
