The device indicates Yann 190 micrograms per cubic meter. The filter is used and the device is not sufficient for the apartment. In addition, the "pollutiomètre" indicates 700 micrograms per cubic meter near the humidifier - including water is not purified. The mother does not want to do too much, she thinks he must also "adapt to living conditions in Beijing." But the diagnosis was motivated to "secure" more his home.

The air pollution every day, and still less an episode of "airpocalypse" like that of the past few days, asked about measures to protect themselves. The recommendations are to "stay inside". But without purifier, the air is in reality as poor quality and out, explain a teacher at Tailormadecc.
And there is often little better with a purifier if the apartment is not effectively insulated. In this area, Beijing has become a hotbed of innovation: all sorts of initiatives have emerged. A Swiss has developed a kind of "pollutiomètre" a very cheap meter (about 50 euros). Professionals offer to expatriates quotes pollution for several hundred euros. The French Yann Boquillod and Herve Robin, they have launched their own application, AirVisual. This gives the air quality in Beijing and 5000 cities around the world and provides forecasts to three days. "We model the weather and pollution data. An algorithm based on artificial intelligence learns the results to draw constantly new conclusions, "says Yann. Their start-up is also in the process of developing a personal device for measuring the quality of accurate and affordable air.
