Why does the Mijia Smart Air Purifier 6 have an odor?

If the Mijia Smart Air Purifier 6 has an odor, please refer to the following information:
New device odor:
The shock-absorbing foam inside the packaging has a slight natural material odor. Because the purifier is in contact with the foam for a long time, it can also absorb some of this smell. The odor will naturally dissipate after the packaging is opened for a while and poses no harm to the human body.
The new device can emit some harmless odors due to the composite filter used. When first started, you can notice smells from the main materials and residual auxiliaries from the manufacturing process. These odors will gradually fade after some usage. This is normal and poses no harm to your health. To speed up odor removal, it is recommended to run the purifier at the highest fan speed in a well-ventilated area for some time. Please use it with confidence.
Odor after more than one month of use:
During usage, the filter absorbs pollutants, which can cause slight odors. Prolonged use and relatively humid environments can also contribute to odor generation. People sensitive to smells can notice this. It is recommended to run the purifier at the highest fan speed for a period, after which the odor will lessen. This odor is not harmful to the human body.
To avoid the risk of a sour smell caused by a damp filter, it is suggested that people in high-humidity areas keep the purifier running continuously and clean the bottom pre-filter approximately every two weeks.
Note:
The filter included with the air purifier is sealed in plastic packaging at the factory to prevent contamination during storage and transportation. When first unsealed, the filter has a slight odor, which will diminish after some use. This is normal and does not pose any harm to your health.
