Air purifier - kuukiseijouki

Japanese: 空気清浄機 - くうきせいじょうき
Air purifier - kuukiseijouki

A device that removes fine particles such as dust and purifies polluted air. It is also called an air cleaner. Dust in the air is mechanically removed by passing it through a fibrous or sponge filter, but a further method is to pass the air between high-voltage electrodes to charge the fine particles and have them adsorb to the electrodes, or adsorption by activated charcoal is also used for deodorization. Air purifiers were not very popular until recently because ordinary homes can be ventilated by opening and closing windows, and it is not easy to purify gases to prevent gas poisoning. However, with the spread of air conditioners, they have begun to be used in automobiles, and recently, with consideration for non-smokers and people with allergies and growing health consciousness, they are also available for office and home use.

Japanese:

塵埃(じんあい)などの微粒子を取り除き、汚れた空気を浄化する装置。エアクリーナーともいう。空気中の塵埃は繊維状やスポンジ状のフィルターを通して機械的に取り除くが、さらに空気を高電圧の電極の間に通して、微粒子を荷電し、電極に吸着させる方法が用いられたり、脱臭のために活性炭による吸着が併用されることがある。なお、空気清浄機は、一般の住宅が窓の開閉によって換気ができること、ガス中毒を防ぐようなガスの浄化作用が簡単にはできないことなどから、最近まではあまり普及していなかったが、エアコンの普及に伴って自動車に用いられるようになり、最近は嫌煙者、アレルギー性疾患者への配慮、健康志向の高まりで、事務所用、家庭用も出回っている。
