hi all, I am moving away and need to sell my Xiaomi air filter. I got it last winter but didn't use it much, no scratches, looks all new. It is the 1st version of Xiaomi which has bigger filter coverage. I got them RMB899+RMB169, would like to sell them RMB750 together. and there is a vase for free if you are interested. Got it last month in a designer shop.
