Finally, a major news outlet (CBS News) does a short segment on a very practical way to potentially greatly reduce COVID infections. I've wondered for months why simple methods like this aren't being used almost universally. Seems to me it could prevent most COVID infections. Ironically, the CBS News anchor (Norah O'Donnell) doesn't really seem to recognize the significance of something so simple being so (apparently) highly effective.

New air purifiers filter at least 90% of COVID-carrying particles, researchers say

"It's a very fixable problem," Prather said. "Once you acknowledge it's in the air, you can remove it using really simple methods like this."

In theory it seems like a good idea, and I sometimes use my HEPA filter air purifier when people visit.

But you really need to conduct a trial so see if air purifiers can reduce coronavirus spread in real-world conditions. It's no good the government buying millions of air filters for use in schools, bars, restaurants, shops and other public places if they are not really effective.

Such a trial appears to have been started in schools in the UK, with results expect by the end of the year.
