Question about Xiaomi Smart Air Purifier 4 Lite

The Mi Smart Air Purifier 4 Lite from Xiaomi is a powerful device for air purification, but its suitability for rooms with vapours from resin 3D printers is limited.

Here are some important points to consider:
- The air purifier has a three-layer filter technology that filters 99.97% of particles down to 0.3 μm, including dust, pollen, smoke and VOCs (Volatile Organic Compounds).
- It also contains activated carbon, which is optimised for the removal of odours and harmful gases such as VOCs. However, effectiveness could vary with specific chemicals and vapours from resin 3D printers.
- There are concerns that the filters of the Xiaomi Air Purifier 4 Lite could wear out quickly, especially if they come into contact with more aggressive chemicals. This could shorten the service life of the filter and make regular filter changes necessary.

To summarise: While the Mi Smart Air Purifier 4 Lite can filter some chemicals and vapours, it may not be the best choice for rooms with heavy exposure to resin 3D printer vapours. It might make sense to look at specialised air purifiers designed explicitly for such applications.
