The pandemic hasn't just changed how CES is delivered - it's changed what's being pushed by some of the firms.
Earlier, we saw Samsung's exercise app for TVs and robot vacuum cleaner - but hygiene in particular has been an odd focus for many.
LG, for example, spent the top of its main press conference not on its flagship TVs - but on "making your life better and cleaner". It heavily featured its portable air purifiers called Puricare, including a version that can be worn on the face like a mask.

The product was announced in August last year, but it still made a top spot on the tech firm's main annual showcase.
And then there's the AirPop Active+ Halo, a $150 mask with a smart sensor in it. The sensor - which the company calls a "halo", connects to smartphone app to monitor breathing, air quality, and whether the filter needs to be replaced. It's due to be released in North America soon.
But these companies aren't making a direct claim that their products protect against coronavirus - because evidence about whether or not it does is patchy.
Which? magazine took a look at the topic in March 2020, as the global outbreak saw sellers advertise air purification as a way to fight the virus.
Viruses are extremely small, but a top-quality air filter can in fact capture some of them. But Which? concluded: "Crucially, though, none of this has been scientifically proven yet, and, in the real world, a lot depends on factors".
The US Environmental Protection Agency says pretty much the same thing.
"When used properly", some filters can "help reduce airborne contaminants including viruses", it says.
But it's only an aid, and "by itself, air cleaning or filtration is not enough to protect people from exposure to the virus that causes Covid-19."
