空气净化器发展历程
Development of Air Purifier
1823年，约翰和查尔斯·迪恩发明了一种新型烟雾防护装置，可使消防队员在灭火时避免烟雾侵袭 。
In 1823, John and Charles Dean invented a new type of smoke protection device, which enables firefighters to avoid smoke attack when fighting a fire.
1854年，一个名叫约翰 斯·滕豪斯的人在前辈发明的基础上又取得新进展：通过数次尝试，他了解到向空气过滤器中加入木炭可从空气中过滤出有害和有毒气体。
In 1854, a man named Johns Tenghouse made new progress on the basis of his predecessors'invention: through several attempts, he learned that adding charcoal to air filters could filter harmful and poisonous gases out of the air.
二战期间，美国政府开始进行放射性物质研究，他们需要研制出一种方式过滤出所有有害颗粒，以保持空气清洁，使科学家可以呼吸，于是HEPA过滤器应运而生。
During World War II, the U.S. government began to study radioactive materials. They needed to diankuaiji.89ix.cn gangzhamen.89ix.cn bjlvyou.89ix.cn bjjiaxiao.89ix.cn bjhunsha.89ix.cn bjhunqing.89ix.cn develop a way to filter out all harmful particles to keep the air clean so that scientists could breathe. So HEPA filters came into being.
20世纪50、60年代，HEPA过滤器一度非常流行，HEPA是个过滤标准，即针对0.3微米的颗粒物，有超过99.97%的过滤效率，它讲求的单次过滤效率。在空气净化器中，达到HEPA标准的滤网风阻太高，而并不适用。
In the 1950s and 1960s, HEPA filters were once very popular. HEPA was a filtration standard, which aimed at 0.3 micron particulate matter. It had a filtration efficiency of over 99.97%, and its single filtration efficiency was emphasized. In the air purifier, the air resistance of the filter which meets the HEPA standard is too high, and it is not applicable.
20世纪80年代 ，空气净化的重点已经转向空气净化方式，如家庭空气净化器。过去的过滤器在去除 空气中的恶臭、有毒化学品和有毒气体方面非常好，但不能去除霉菌孢子、病毒或细菌，而新的家庭和写字间用空气净化器，不仅 能清洁空气中的有毒气体，还能净化空气，去除空气中的细菌、病毒、灰尘、花粉、霉菌孢子等。
In the 1980s, the focus of air purification has shifted to air purification methods, such as home air purifiers. In the past, filters were very good at removing odors, toxic chemicals and toxic gases in the air, but they could not remove fungal spores, viruses or bacteria. The new air purifier for households and offices could not only clean the toxic gases in the air, but also purify the air and remove bacteria, viruses, dust, pollen and fungal spores in the air.
从二十世纪90年代后期开始，随着除菌除臭需求增加，空气净化器领域掀起了一股“抗菌热”。空气净化器也在1996年采用光催化剂滤芯提高了除菌除臭性能。
Since the late 1990s, with the increasing demand for deodorization and deodorization, the field of air purifiers has set off a "anti-bacterial fever". The air purifier also used photocatalyst filter element in 1996 to improve the performance of deodorization and bacteria removal.
在2002年以后，受到SARS的蔓延、新型流感流行等影响，人们对空气净化器抗病毒的需求越来越大。开发并为空气净化器配备了“流光能”技术。该技空气净化器术是利用分解（氧化）滤芯捕捉细菌和病毒。
After 2002, people's demand for anti-virus air purifier is increasing due to the spread of SARS and the new influenza epidemic. Developed and equipped with "streamer energy" technology for air purifier. The technology of air purifier uses decomposition (oxidation) filter to capture bacteria and viruses.
2008年，在清除空气中有害物质的对策之外，为了满足消除房间干燥的需求，空气净化器又增加了“加湿功能”。
In 2008, in addition to eliminating harmful substances in the air, in order to meet the needs of eliminating room drying, the air purifier added a "humidifying function".
截至2013年，市场上绝大多数的空气净化器，特别是万元以下的空气净化器，其颗粒物滤网都不能称之为“HEPA”。
As of 2013, most of the air purifiers on the market, especially those under 10,000 yuan, can not be called HEPA.
2014年，极炭心滤芯技术首次在空气净化器行业得到运用。
In 2014, polar carbon core filter technology was first used in the air purifier industry.
