[Negative oxygen ion function] The built-in negative oxygen ion generator can not only purify the air, but also improve the alveolar ventilation function and increase the oxygen absorption rate.
[Simultaneous oxygen intake for two people] 93% high oxygen concentration, stable oxygen output, even if two people use it at the same time, still high oxygen concentration.
[One-row button remote control] Intimate infrared remote control, which can control a distance of about 18 meters, the elderly do not need to get up frequently. The protruding button design can be controlled at night.
[Low-noise cooling fan] Using high-end noise reduction technology, the noise is more thorough, and ultra-low noise does not affect sleep. The operating noise is less than 30db.
[Multi-layer filter] The oxygen system performs coarse filtering, fine filtering, and three-stage bacteria filtering on the input air, and the filtered oxygen is fresh and clean.
