根据净化需求来分，空气净化器可以分为：
According to the purification requirements, the air purifier can be divided into:
（1）纯净化型。如果位于室内湿度较适中的地区，或者对空气质量要求不太高，则选购纯净化型的空气净化器就满足需求了。
(1) purification type. If it is located in an area with moderate indoor humidity, or the air quality requirements are not too high, the purchase of purified air purifier will meet the demand.
（2）加湿净化型。如果是位于较干燥的地区、经常开空调被空调抽湿而造成室内空气干燥、或者对空气质量要求较高，则选购一台带有加湿净化功能的空气净化器，将是最适合的选择。
(2) humidification and purification type. If it is located in a dry area, the air conditioner is often turned on to be wet by the air conditioner, resulting in the drying of indoor air, or the air quality requirements are high, then choosing an air purifier with humidification and purification function will be the most suitable choice.
（3）智能型。如果喜欢自动化操作、智能监控空气质量、或者体现高贵品味、或者用来送礼需要更体面，则选购一台智能型的空气净化器便是最佳选择。
(3) intelligent. If you like automatic operation, intelligent monitoring of air quality, or embodiment of noble taste, or need to be more dignified for gift giving, an intelligent air purifier is the best choice.
（4）车载型。如果是用于轿车内空气净化，需要专门净化汽车异味、汽车甲醛等车内污染，并能够专门放置于车内的空气净化器，所以，最优选择为车载型空气净化器。
(4) vehicle type. If it is used for car air purification, it needs to specially purify car odor, car formaldehyde and other car pollution, and can be placed in the car air purifier. Therefore, the best choice is car air purifier.
（5）桌面型。即放置于桌面，净化桌面周围一定范围内的空气，保护桌面附近人的健康的空气净化器。如果经常坐在电脑前、办公桌前、或者书桌前，但是所处的室内面积不小，或者是公共场所，自己掏钱买一台大型的空气净化器并不划算，也不时尚，则桌面型的空气净化器就是较好的选择。
(5) desktop type. That is, put it on the desktop, purify the air around the desktop within a certain range, and protect the healthy air purifier near the desktop. If you often sit in front of a computer, a desk, or a desk, but the indoor area is not small, or in a public place, it is not cost-effective or fashionable to buy a large air purifier at your own expense, the desktop type air purifier is a better choice.
