No bactericide can be added to the humidifier.
The amount and concentration of bactericide directly sprayed in the air or in daily use are small and low, and generally, it will not endanger health. However, the humidifier will enter the air through atomization, and the concentration will increase greatly. After being inhaled into the human body, the chemical reagents in it will stimulate the epithelial cells of the lungs and bronchi, and the cells will be damaged after long-term use, causing diseases of different degrees.
