What do the ions marked on the air purifier mean?

Ion means negative ion, so this is a negative ion air purifier. Negative ion air purifier: it is an environment-optimized electrical appliance that uses negative ions generated by itself to purify, remove dust, deodorize and sterilize the air. The difference between it and the traditional air purifier is that negative ions are used as action factors to actively capture harmful substances in the air, while the traditional air purifier uses fans to exhaust air and filters dust, which is called the purification principle of passive adsorption filtration. The filter screen needs to be replaced regularly, while the negative ion air purifier does not need consumables.

Compared with atmospheric coarse particles, PM2.5 has a small particle size, is rich in a large number of toxic and harmful substances, stays in the atmosphere for a long time and has a long transportation distance, which has a great impact on human health and atmospheric environmental quality. Because the smaller the particle diameter, the deeper it enters the respiratory tract. Particles with a diameter of 10 micron are usually deposited in the upper respiratory tract, while particles below 2 microns can penetrate into bronchi and alveoli, directly affecting the ventilation function of the lungs and leaving the body in a state of hypoxia. In the face of pm2.5 pollution, the traditional filter air purifier cannot remove pm2.5.

Special high-energy and high-ozone ultraviolet beams are used to irradiate malodorous gases, which can crack malodorous gases such as ammonia, trimethylamine, hydrogen sulfide, methyl hydrogen sulfide, methyl mercaptan, methyl sulfide, dimethyl disulfide, carbon disulfide, styrene, sulfide molecular bonds such as H2S, VOC, benzene, toluene and xylene, so that free pollutant molecules can be oxidized and combined with ozone to form harmless or low-harm compounds such as CO2 and H2O.

Free oxygen, namely active oxygen, is generated by decomposing oxygen molecules in the air with high-energy and high ozone ultraviolet beams. Because of the imbalance of positive and negative electrons carried by free oxygen, it needs to be combined with oxygen molecules to generate ozone.
