PHG Koninklijke Philips NV

LONDON--Dutch conglomerate Royal Philips N.V. (PHIA.AMS) and Alibaba Group (BABA), China's newly-listed e-commerce giant, said Tuesday they launched a "smart" air purifier that will let customers mitigate the problems of air pollution in China's megacities.

Alibaba will support Philips' air purifier with cloud computing services to store and process data from the connected device, allowing users to operate it in real time, as the first project under a new agreement to collaborate on IT-infrastructure services.

The device can send alerts to the users' mobile device when the indoor air quality reaches unhealthy levels or when its filter needs to be replaced.
