The Xiaomi Y-600 device is partially suitable for removing cigarette smoke, but it has some limitations regarding this function.

- The device has a 3-layer filter arrangement consisting of a pre-filter, a fine dust filter and an activated carbon filter. The activated carbon filter is specially designed to eliminate unpleasant odours, including smoke.
- The activated carbon filter in the Xiaomi Y-600 can therefore help to reduce cigarette smoke and other unpleasant odours.

However, it is important to note that the effectiveness of the filter depends on various factors, such as the intensity of the smoke and regular filter maintenance.
