Many people are now starting to realize the benefits of investing in air purifiers for their home to get rid of the contaminants and pollutants that could potentially cause harm to their own or their family’s health. Increasing numbers of people are starting to recognize that they can enjoy better health by investing in air purifiers that remove pollen, dander, dust, tobacco smoke, mold spores and other small particles from the air, so it makes sense that in some places where air pollution is a serious problem the idea of having a larger version could be the ideal solution to the population’s problems.
China’s Air Pollution Problem
China is one of the countries that is known to have a major problem with air pollution in its major cities, and the problem is causing health problems for many of the population. Now, the Chinese government have decided to take steps to rectify the problem so that the people who live in these highly polluted areas can enjoy better health.
The Chinese government have pinpointed the city of Xi’an in the north west of the country as a pollution hotspot, and have now constructed an enormous air purifier which is designed to combat the problem of air pollution in that area. The purifier is 328 feet in height and, since its first day of operation, it has so far managed to produce over 353 cubic feet of fresh and cleaned air every day. The result is that the air quality in the four square mile area surrounding the purifier tower has improved noticeably.
While the large white cylindrical tower is the most noticeable thing about the air purification system it is, for want of a better word, the tip of the iceberg. This is claimed to be the largest system for air purification anywhere in the world, with a huge greenhouse network at the base of the tower where the polluted air is brought in and heated up by the trapped solar energy from the sun. As the hot air rises naturally, it moves up through the numerous cleaning filters in the tower.
The tower is run by the Chinese Academy of Sciences’ Institute of Earth Environment, and they are monitoring its effects on the local environment very closely. Over 12 sensors are in use tracking the levels of pollution and they have revealed that the air purifying tower has reduced the number of dangerous particles in the air by 15% during times of heaviest pollution.
Based on the success of this project so far, researchers are already working on the plans for a much bigger tower measuring 1640 feet in height which could clean all of the air over a small city. This could be extremely beneficial in China, since the nation’s problem with smog has become a serious issue. Beijing has tried to resolve the problem by recently announcing that a plan was underway to replace the city’s 67000 taxis which run on gas with those which are electrically powered, and air purifying bicycles are already in place in the capital. Beijing’s authorities have also worked with a Dutch designer called Dan Roosegard on developing a tower which sucks in smog and which measures 23 feet in height – although this is much smaller than the new air purifier tower in Xi’an.
Dutch Developments In Air Purification
Although China’s Xi’an purifier towers claim to be the world’s biggest air purifier, this may only be in terms of its height. This is because in The Netherlands, a group of Dutch inventors have recently unveiled their latest invention – a big outdoor air vacuum cleaner which can filter huge amounts of contaminants from the air.
The purifier is capable of cleaning around 800,000 cubic metres of air every hour, with huge columns of air passing through the air filter and coming out clear. The industrial filter used for the vacuum cleaner was showcased in an exhibition in the Dutch capital city, Amsterdam. It is a huge 8 metre long industrial filter that is made from steel and when it is placed on the top of a building it functions in the same way as an enormous vacuum cleaner.
The developers behind the project claim that it can suck air into its filter from a radius of 300 metres, and from a height of 7 kilometres above it. It can also filter out 95% of the ultra-fine particles in the air and 100% of its fine particles, both of which are known to cause harm to the public’s health.
Burning fuels like wood and industrial combustion cause fine particles to be released into the atmosphere, while ultra-fine particles come from vehicle emissions and aeroplanes. Since 90% of people living in Europe are allegedly exposed to such a high level of harmful particles, the invention of this huge filter is quite timely.
It is interesting to note that Daan Roosegaarde, a Dutch designer worked on the Beijing Smog Free Tower and its ozone-free ion technology, helping to spread the knowledge from the Netherlands to the other side of the world which suffers from a serious pollution problem of its own.
The Importance Of Clean Air
Cleaner air is a priority for countries around the world, since both developed and developing nations are experiencing an increase in pollution in their environments, and especially within densely populated cities. By installing large air purifier towers like the one in Xi’an, cities could well find that public health is given a much needed boost and the local populations suffer from fewer respiratory problems, allergies and even more serious conditions that are now being associated with a high level of air pollution.
While it’s fascinating and exciting to see countries taking such drastic measures to cut down on airborne pollution, the best thing most of us can do is start small. Health-conscious consumers can install air purifiers in their own homes to cut down on the number of potentially harmful contaminants in their home environments to improve their quality of air within their own houses and to reduce the incidence of allergies within their own family.
