Hi @tukebay,

Have continued to watch from the sidelines with interest and have to say I was disappointed that WRG/PO3 dropped the ball a little on their water technology, but I do understand that Air Purification would be a natural diversified step further into disruptive technology.

Having been involved in writing ASX ann's, I was not surprised to see that retraction and rewrite, especially for that marketing sentence making demands of state governments.

Regarding the COVID claims, I think you only need to look at the microfiltration to address that and see what aerosol nano particulates are captured by their filtration system and then neutralised by the FRG technology . The molecular weight for COVID ( SARS-CoV-2 3CL^pro) is 33796.64 Dalton which is 5.6120636119e-14 micrograms. Good quality Hepa filters used in Phillips portable air filtration systems will, in theory, remove 99.97% of SARS particles, being tested now, I believe. I use two Phillips units at home now.

"While Philips air purifiers have not been verified to remove SARS-CoV-2 aerosols from the air – Philips' HEPA filters can remove 99.97% of particles as small as 0.003μm [6] (equal to 3 nm), smaller than the smallest known virus [7], from the air that passes through the filter. A similar performance is expected for SARS-CoV-2 aerosols. An independent institute tested that Philips’ air purifiers can reduce the levels of Influenza A (H1N1) virus aerosols by 99.9% in a test chamber, within ten minutes after being turned on [8].

I would like to see more comprehensive technical papers released on the benefits of PO3's system over its competitors in treating aerosol viruses. Theoretically, it should work the same as 3 stage reverse osmosis systems for water. Heavy filtration (sifters) - nano filtration (collectors) - UV (bioparticulate destruction).

I have been following WRG/PO3 back since 2010. Still a little sceptical but will hold my re-investment until the product is marketable.
