空气净化器发展历程
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

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 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.
