This, combined with other measurements (like washing hands frequently, no coughing in hands, or staying home when you have a cold, and proper ventilation), could be a reason to stop the lockdowns. We can go back to the office. It might also help local businesses like restaurants, cafes, small shops to be visited indoors for a longer amount of time than currently possible.

I'd like to mention this video that goes into detail about aerosols and their behaviour in unventilated areas: https://www.youtube.com/watch?v=jhM9Zt5tZjY

This isn't news this is an advertisement. Ionization of air has long been a thing that's known to kill viruses and bacteria. The problem that they totally gloss over is the production of ozone which is quite harmful to people.

It's like they are trying the "on a iPhone" gimmick to make you think this is new technology. Look around you'll find ionizers everywhere especially at shops because they reduce offensive smells in the air.

If you're looking for something in your house UV light filtration works just as well for killing viruses and bacteria, there's inexpensive home units already, and it doesn't produce ozone. The health problems from ozone aren't something you want to deal with.

It's also super expensive compared to opening the windows once in a while, and ensuring good air circulation in the first place.
