Adopt anion technology: Extremely purify the air and remove the substances including dust, odors, , etc. Effective prevention of air-conditioning diseases: anions may improve metabolism, maintain a air, relieve fatigue. Battery charger High quality is a handy for digital . Produce active oxygen molecules: The anions may release the negative electric charges from oxygen molecules to make them more active. Therefore, the lungs absorb 20% more than 15% oxygen and expel more carbon dioxide. Broad spectrum and efficient ozone: ozone may kill , and will be deoxidized into oxygen in without secondary pollution, which the chemical agents can not achieve. Automatic timed sterilization: automatic timed operation of ozone, 15 minutes after the start, a time of sterilization is finished and the machine automatically after the ion starts to work off. Protect eyes and refresh. Negative ion positive charge related to reduce the static radiation and protect your eyes. Adding any fragrance: fragrance tablets that slowly release perfume adopted.
