Adopt anion technology: Effectively purify the air and remove substances including dust and odors. Effective prevention of air-conditioning related discomfort: Anions may improve metabolism, maintain fresh air, and relieve fatigue. High-quality battery charger is convenient for digital devices. Produce active oxygen molecules: The anions may release negative electric charges from oxygen molecules, making them more active. Therefore, the lungs absorb 20% more oxygen than 15% and expel more carbon dioxide. Broad spectrum and efficient ozone: Ozone may kill bacteria and will be deoxidized into oxygen without secondary pollution, which chemical agents cannot achieve. Automatic timed sterilization: Automatic timed operation of ozone, 15 minutes after startup, a cycle of sterilization is completed and the machine automatically turns off after the ion function starts. Protect eyes and refresh. Negative ions neutralize positive charges to reduce static radiation and protect your eyes. Adding fragrance: Fragrance tablets slowly release perfume.
