  • 1. How long does the filter last?

    It is recommended to replace the filter every 6–8 months.

  • 2. How loud is the purifier?

    Noise range: 30-60dB. It is as loud as a fan when it’s on high mode, but you can barely hear it when it’s on night mode.

  • 3. What is the applicable area?

    It is recommended for large room of 40㎡. The purifier is big enough for home and office. It is not recommended to put it in rooms larger than 40㎡ because this will affect the effectiveness of air purification.

  • 4. Does this filter remove cigarette smoke and smell well?

    This air purifier absorbs the smoke from cigarettes and cigars. But it can only reduce the smell, not completely remove it. The charcoal filter will absorb the smell for the first time. After some time, when the filter saturates, this smell will be desorbed from the filter. Please change the filter more frequently.
