I bought 2 of these air purifiers (15.02 for 8.037 and 24.02 for 6.291), one for my bedroom, the second for my mother-in-law (after lung surgery). Immediately on the first night, they noticed a difference in the air - it became fresher due to its circulation in the room. Basically it is on automatic mode, periodically, when we are absent from the bedroom or leave the house, I turn it on at full power. Recorded a videocomparison of Xiaomi 3C and 3H cleaner models -
