Can you point to any ASX announcement that mentions Covid??
An ASX announcement is where the company must release any market sensitive information.

"Not affected by the air humidity and can operate in conditions of up to 100% humidity."
What has that to do with anything??Re-read that carefully, no-one has claimed that the device will be 'affected' by humidity..
Changes in humidity will affect the free radicals produced, according to the company itself!!

The company's own documentation clearly states that different humidity levels will produce a range of free radicals, varying from mostly ozone in dry air to more hydroxyl radicals in high humidity, which I have linked to in the past...

pg 6
"However, in a dry gas one can selectively generate O* radicals leading to ozone production."
(This is because in dry gas there is no hydrogen atoms to form the OH free radicals with.)

pg 10
"However, having high amount moisture in the feed air is a pre-requisite to generate high amount of OH* radicals."

That's company documentation, not a google search...
