In July, I wrote about the idea of killing Covid-19 viruses with appropriate technology. In the meantime, a lot has happened.
As the first electronic respiratory protection that kills 100% of viruses, the "Securer" should be available from fall 2022. The current status is presented in a recent press release:
"SecureAir GmbH is currently looking for technology partners who would like to produce under license and/or distribute the product or acquire the complete technology as the global market leader."
I held the current state of the product in my hands yesterday. A lot has happened here, it feels very valuable, looks good and all the reviews show that it works.

It remains exciting.
