The air pollution ATM is at 366 PM 2.5 when this post was made. The chart now tops out at 300 with the hazardous description; the US embassy got rid of the crazy bad description given that the Chinese government wasn't so happy about that.

We went all the way up to 800 and 900 last January; we got up to 424 just last week. 0-50 is considered clean air, Salt Lake City institutes burn bans whenever their AQI goes above...35. There was a scandal when it got to 55 or so last year.

This is a very neat idea, though I suspect they'll ultimately want a more powerful fan. Note that high quality air filters also have a carbon pre-filter that gets changed more often than the HEPA filter, and having one ought to make your HEPA filter last much longer, especially in somewhere like Bejing.

I'm still trying to reconcile the $300 price tag of yours with the price tag of a carbon filter (5 on amazon) HEPA filter (70 on amazon) and box fan (30 on amazon). Is there really 200 dollars worth of plastic, assembly, marketing and IP in the the whispure? Or is there one important element I'm not accounting for (perhaps fan power, fan noise, some kind of PID, or sensors to check filter health)

Can't you just do this with a normal box fan and a hepa air filter you buy for 7usd at the market?

Yes. I've been doing this for years.

It is amazing how much the air flow is cut down by the filter, though.

a quote from the movie with the mock history of dr kellogs:

health is the easy way to a fool's wallet.

that said I have 3 expensive of those filter at my home. not that one, 3 other different brands. The main factor for my purchases were silence. and ironically the only one that was silent is a discontinued sharp model that sold for $150. all the $300 models are awful. specially the blueAir one that focus all it's marketing on being silent.

Nice! I had read something similar for a wood workshop here: http://woodgears.ca/dust/air_cleaner.html Seems to be quite effective. Also, if you're into woodworking, woodgears is probably one of the best, if not the best on the net.

Hopefully that's in addition to a dust collector https://www.google.com/search?q=dust+collector

one reason might be that the market is much smaller for those then for fans or filters separately (smaller order quantities for the manufacturer = higher costs)

I think that people in Beijing and other Asian or American countries should stand up more often and force their governments to install filters on each fabric's smoke pipe and charge those who don't comply with a big fine. You can then open a petition that votes for using the money generated from that fine to for deploying fuel-less car alternatives… Come on, tell me you're helpless and dependent on your government an…

While I agree in general, one of the biggest sources (if not the biggest) of dust in Beijing's air is the desert Gobi. It will be pretty hard to build an appropriate filter. ;)

In my experience Beijing's air is really "special". Hot, humid, dusty. Not my favorite environment.

Guys at http://aaaiiirrr.com/ are doing the same thing, but Open source.

I don't see anything on their website. Looks like a new install of wordpress.
