We Can Kill COVID! Here's the Proof., page-57

LOL, I just linked to 2 companies that create free radicals that kill viruses and bacteria, so no need to look any further.

BTW I wouldn't buy any of them because of the free radicals they produce.

I was initially really looking forward to purchasing some Purifloh units for my own use when I first bought shares 2 years ago. Now after a lot more research I'm not interested in any type of free radical 'air purifier' from any company.

6 years of being licensed to sell the technology and still no product, states a lot by itself..
