1、预过滤器去除空气中的较大颗粒物，以延长静电吸附装置的清洗时间。
1. Pre-filter removes large particles in the air to prolong the cleaning time of electrostatic adsorption device.
2、静电吸附装置可以吸附空气中的微小颗粒物，当空气中的微小颗粒物通过静电吸附装置时，带上正电荷后牢固地吸附到静电吸附装置的负极集尘片上。HEPA高效过滤器可以吸附空气中的微小颗粒物，当空气中的微小颗粒物通过HEPA高效过滤器时，被吸附到HEPA高效过滤器上。
2. The electrostatic adsorption device can absorb the fine particles in the air. When the fine particles in the air pass through the electrostatic adsorption device, they are firmly adsorbed on the negative dust collector of the electrostatic adsorption device with positive charges. HEPA high efficiency filter can absorb minute particulate matter in the air. When the minute particulate matter in the air passes through HEPA high efficiency filter, it is absorbed to HEPA high efficiency filter.
3、活性碳过滤器去除空气中的有害气体，有害气体包括氨气、甲醛等。
3. Activated carbon filters remove harmful gases in the air, including ammonia and formaldehyde.
4、紫外线杀灭空气中的各种微生物(病菌)。
4. Ultraviolet rays kill all kinds of microorganisms in the air.
5、当紫外线照射其周围的光触媒时，激活光触媒过滤器从而有效分解有害气体。
5. When ultraviolet light irradiates the photocatalyst around it, the photocatalyst filter is activated to effectively decompose harmful gases.
6、负离子发生器释放负离子，使空气更加清新。
6. The negative ion generator releases negative ions to make the air cleaner.
