Product Specifications: 200 * 120 *120mmBenefits:1 manufacturer of reactive oxygen species: negative oxygen ions can effectively activate molecular oxygen in the air to make it more active and more easily absorbed by the body， effectively preventing "Air conditioning disease."2 improvement in lung function: the body after inhalation of oxygen anions， lung can absorb oxygen 20%， while more than 15% of carbon dioxide.3 promote metabolism: activate the body enzymes， promote metabolism.4 enhanced disease resistance: ability to respond to change the body， active reticuloendothelial system function， enhance the body immunity.5 improve sleep: negative oxygen ions， can be uplifting， work efficiency， but also improve sleep， a significant analgesic effect.6 bactericidal function: negative ion generator will also generate a lot of negative ions produce small quantities of ozone， both of which combined more easily adsorbed viruses， bacteria， to produce changes in the structure or energy transfer， resulting in his death.7 fresh air， smoke and dust: negatively charged ions and floating in the air with a positively charged electrode and smoke and dust， making it a natural deposition. Dust sterilization to reduce secondhand smoke is more effective. Environmental health visible.8 protective effect: in television， high-voltage electrostatic computer， in front of a layer of ions to form an effective protective layer to reduce television， computer-generated high-voltage electrostatic damage to the eyes， effectively preventing myopia， while reducing dust and damage to the TV， computer， etc. .
