车载空气净化器

车载空气净化器，又叫车用空气净化器、汽车空气净化器，是指专用于净化汽车内空气中的PM2.5、有毒有害气体(甲醛、苯系物、TVOC等)、异味、细菌病毒等车内污染的空气净化设备。

车载空气净化器工作原理

车载净化器也叫车用净化器或车载空气净化器,通常由高压产生电路负离子发生器、微风扇、空气过滤器等系统组成。 它的工作原理如下：机器内的微风扇(又称通风机)使车内空气循环流动，污染的空气通过机内的PM2.5过滤网和活性炭滤芯后将各种污染物过滤或吸附，然后经过装在出风口的负离子发生器(工作时负离子发生器中的高压产生直流负高压)，将空气不断电离，产生大量负离子，被微风扇送出，形成负离子气流，达到清洁、净化空气的目的。

车载空气净化器类型

滤网型车载空气净化器

滤网型车载空气净化器可以有效净化汽车内的灰尘、甲醛、苯、细菌等有害物质。

静电集尘型车载空气净化器

静电集尘型车载空气净化器是需要与其它器材配合才能达到高效的净化效果，因为静电集尘型车载空气净化器并不能完全吸附并消除异味，也无法完全分解有毒化学气体。同时，其净化效果和净化效率会随着悬浮微粒的累积增加而递减，需要经常清洗集尘板以恢复其效果与效率，故维护成本较高。

臭氧车载空气净化器

臭氧车载空气净化器是工作原理是产生出来臭氧来净化车内空气，以达到改善车内空气质量的效果。虽然，臭氧对细菌有一定的效果，特别是针对胺、烟碱、细菌等。但在使用此类型车载空气净化器时，要适当注意车厢内臭氧的浓度，因为臭氧如果浓度过高时，会产生二次污染，对人体健康产生危害。

净离子群车载空气净化器

净离子群车载空气净化器使用净离子群发生器喷洒出独特、安全的净离子群,去除甲醛、苯、细菌、异味以及过敏原等;轿车专用车技，运用康达效应，使净离子群到达车厢内的每一角落，净化不遗角落;使用约长达17，500小时才需要换离子发生器。

水过滤车载空气净化器

水过滤的原理主要模拟大自然的降雨过程，通常降雨的时候会产生雷电，这时候会有大量的臭氧产生，会对空气中的病毒和细菌进行杀灭，同时雨水对空气中的颗粒物进行湿沉降，所以雨后我们呼吸到的空

气都是非常清新的没有污染的。水过滤车载空气净化器主要是通过涡轮风扇直接吸入到风槽里面这时银离子和负离子对空气进行杀菌消毒，然后再将空气排入水槽里面进行湿沉降，最后通过涡轮抽风机将水槽里面经过净化的空气排出，排出去的空气因为经过了水的湿沉降，所以空气中含有一定的水分，相当于一个自然的空气加湿器。

车载空气净化器产品特点

1)多重功效，超效净化

空气净化器拥有多重净化功能：负离子+超级活性炭。能够主动净化车内每个部位，能够有效杀害空气中的有害病菌、细菌，祛除灰尘、烟尘及异味。

2)杀菌抗病，拒绝流感

负离子能够有效的预防疾病，杀菌，改善肺功能，促进新陈代谢。茶树精油，是几个世纪以来澳洲土著居民的消炎杀菌灵药，它通过破坏细菌、病毒的细胞组织及能量源，能有效消灭车内的细菌病毒。

3)天然香薰，提神醒脑

柠檬茶树精油是澳洲独有的一种植物，稀有、珍贵。清新的柠檬香带有木质低调，提神醒脑，舒解压力，令人心情舒畅愉快。

4)加湿美肤，干燥不在

适当的湿度是健康生活的必备条件，开车的过程中容易因空调造成干燥、皮肤紧绷。喉咙咽干的现象。安程悠乐森空气净化器的加湿功能可改善干燥的车内环境，保持肌肤水润嫩滑，同时还能降低空气中的浮尘颗粒，去除静电。

5)空气接触，便捷易用

贴心空气触控设计，按键简单、易懂，轻松触动健康生活。简约杯型设计，放在汽车水杯位上，直接插在点烟器使用即可，不需要占用额外空间。实用轻巧，随取随用。

6)时尚设计，便捷应用

空气净化器产品外观设计前沿时尚，瓶盖采用施华洛世奇元素点缀而成，光彩夺目。为爱车带来独特装饰，尽享奢华品味。更有10款星座幸运颜色可选，满足不同个性要求。
