Xiaomi Company has released a compact air purifier Mi Air Purifier 2. Unlike the first version of the device, the power of the new cleaner cut. Effectively Mi Air Purifier 2 will be able to work only in rooms up to 29 square meters. For large rooms we recommend using several cleaners simultaneously. The device is able to clean 330 cubic meters of air per hour. At the same time it collects 99.5% of the particles with a diameter up to 0.3 micrometer. Room area of 23 square meters cleared in less than 10 minutes. Such devices are extremely relevant to the major cities of China, especially in Beijing. Recall himself Mr.Jack Ma, founder of Alibaba, complained about the horrible pollution and terrifying ecological situation in the region.
