Considering how much backlash there is around valved respirators, a purification system that blasts aerosolized droplets of spit out into the air seems like an obvious failure
I think the target market is less “COVID” and more “Beijing air pollution”.
A lot of negativity here but I guess the target market is locations where the air pollution is bad enough that the benefits of escaping it outweigh looking like an extra from a sci-fi B-movie. I remember hearing on the radio in London how air pollution was going to be very bad one day approaching 10 on some scale. A scientist was being interviewed and was asked "Where would the pollution in Beijing be on this scale?"…
Any day there AQI is below 100 in any of the Indian metros is a good day.
Visited most cities in India (Delhi, Mumbai, Hyderabad, Bangalore) and the pollution is atrocious. I wanted to return back but had to stay on due to a business trip. I can't imagine why/how anyone would want to live in any of the big cities in India. Love the country though.
There is a strong within our executive team to offshore to Latin American countries.
A.K.A 'Snot Cannon' I can see this has having the similar type of negative public health impact as the Dyson Blade dryers in public toilets, simply circulating fecal matter further in an enclosed space. Naomi Wu with the critique: https://twitter.com/RealSexyCyborg/status/150912514143903334...
This seems like a stretch. Barring some rather unexpected effect, this device will not change the amount of aerosolized pathogen emitted by a person. At most it will change the distribution — the aerosols will be presumably be mixed into a larger volume of air. So maybe they will spread somewhat father, but, if so, they’ll be more dilute.

This Dyson device does not have source control, and yes, it is a super-spreader device.
There is proof that such devices are super spreading tools: hospital administrators wore a blow up costume in to a Kaiser Hospital ER and caused a huge COVID-19 outbreak.
This was when contact tracing was in effect in California.

Earlier quoted context omitted.
Your breath (what you exhale) always contains substantial amounts of moisture (and yes, potentially virions). It does not matter if you speak or not. It does not matter if the environment is cold or not. There is no "simple warm air" out of your lungs. I agree with mtn_nerd, you must be trolling. Considering your choice of words, you're probably well aware of that.
The breath you see in cold weather is not aerosols but condensed moisture. I don't know how pointing out this trivial fact can be construed as trolling.

BTW, if any HNers know of any existing headphones with good noise isolating microphones, please let me know.
When reality has become so weird that half of HN can't detect an (albeit early) April fools' joke... Anyway, good job Dyson!
Joke's on me. Reality is weird.
