1Negative ions themselves have a negative charge. When they encounter dust and other particles in the air, the positive and negative phases gather, thereby condensing the dust and other substances into clusters, increasing the weight of the dust and making it fall on the ground, thus achieving the effect of purifying the air. 2Negative ions are a natural factor which have a good effect on improving sleep. 3Negative oxygen ions can effectively strengthen the ciliary movement of the tracheal mucosal epithelium, affect the activity of respiratory enzymes in the epithelial villi, and improve the secretion function of the alveoli and the ventilation and ventilation function of the lung. 4With a portable lanyard, easy to carry, purifying the surrounding air at any time. 5With 2000000/m negative ion concentration, USB rechargeable, you will get high quality air and reduce unpleasant smell anytime.
