> I wonder if you'd put cotton wool, how effective it would be.

Not very. Wet wool is better, but only as long as its wet and clean.

> XIAOMI Mi Air Purifier 2 straight from China

Interesting question. Does the removal of particulates offset the health impact of its cheap plastics?



Does anyone know what the actual smell of "chinesium" comes from? The smell of artificial rubber products from china, like remelt and cancer.


I bought a mechanical product like that one time and had to leave it outside for about a month before it off gassed completely


Happened to me, too. Once with a dog house, and again with a set of car floor mats. The floor mats are still out there.


Wool fiber diameters are around 20 micron - HEPA can have glass fibers below 1 micron, and big box retail grades are often 5 - 10 micron. Smaller fibers = better filters.


> health impact of its cheap plastics

Do you mean the health impact of when the device is thrown away?


I think they mean of small plastic particles coming off the cheap device and polluting the air.


More likely they mean volatile organic compounds (VOCs)


Never heard of this. Also, how would it differ from any cheap plastics coming off any cheap fan made partly or wholly out of plastic?


Any source on that?
