No one here is saying this is a cure for coronavirus. But as a protective measure the air filter has been tested in the past to capture viruses and bacteria including the initial strain of coronavirus(it hasn’t been tested yet on the new virus but the function of the filter should likely be the same as it captures tiny particles). Obviously it’s not a cure to someone infected but can clean the air if the virus is airborne.
Where do you see that here prytel. I would say this is 10 times better than a heppa filter hence the high price which is a good price for what you're getting.
