In recent years, due to the country's high regard for air quality and its continuous efforts to deal with air pollution, the overall air quality in China has been significantly improved. The severe smog days have gone forever.
Although outdoor pollution is governed, while we are pleased with the continuous improvement of outdoor air quality, we can not forget about the indoor air quality that is closely related to ourselves. Because the improvement of outdoor air quality does not mean that there is no problem with the indoor air .
It is well-known that indoors as a relatively closed place is very easy to breed bacteria, microorganisms and other pollutants .In addition, indoor or dust, particulate matter, allergens, the accumulation of pollutants, which again particles as the indoor most common 'visit By' .
Particles (also known as dust), is uniformly dispersed in the air of various solid or liquid particles, can be divided into primary particles and secondary particles, of which secondary particles are mostly sulfur dioxide and nitrogen oxides, the human body Respiratory system stimuli, which in turn induce a series of respiratory diseases.
At this point, some people may say that the original particles so terrible. Indeed the dangers of particulate matter can not be underestimated, but even more terrible is the small particles in the particulate matter. Then some people have to ask, is where the fine particulate matter? ?
That fine particles in the end is how the case? In order to solve everyone's doubts, Xiao Bian today to give you a good grilled a par fine things, so that everyone has a profound understanding of it.
What is fine particles?
First of all, fine particles in aerodynamics refers to the equivalent diameter of 2.5 microns or less of a class of particles, it can be suspended in the air for a long time, when the concentration of air in the higher concentration of fine particles represent the more serious air pollution. Due to its long residence time and long transport distance in the atmosphere, it is easy to cause serious harm to human health due to its small particle size and large area, which are easily attached by toxic and harmful substances.
Also worth mentioning is the often overlooked air of less than or equal to 0.3 microns of solid particles (PM0.3) It not only has all the characteristics of the above PM2.5, more serious is the release of PM0.3 The range is far more than 1000 km, so compared to the traditional PM2.5 fine particles, PM0.3 on human health and atmospheric environmental quality will be greater.
The source of fine particles
There are two main sources of fine particulate matter, one is naturally occurring fine particles from the soil in nature, pollen, bacteria and volcanic ash or coal dust volcano eruption, and the second is caused by man-made, which includes fuel combustion, Secondhand smoke, car exhaust and other fine particles produced.Often ignored by PM0.3, for example, the source is very wide, can be described as covering all aspects of our lives.In the outdoor more than 90% PM0.3 Exhaust gas from power plants, factories and automobiles, as well as heavy metals such as mercury, cadmium, lead, etc. For home use, PM0.3 mainly comes from decoration, home furnishing, paints and adhesives, etc. It can be seen that indoor or outdoor , PM0.3 small particles really can be described as ubiquitous, always accompanied by us, affecting our health.
Hazard of fine particles
PM0.3 small particles in addition to a wide range of sources, its harm should not be underestimated .First because PM0.3 diameter is small, so only through breathing into the lungs and obstruction of alveoli PM2.5 compared to its can be described as' All-pervasive ', can damage the body's multiple systems and organs. This includes breathing, immunity, blood and circulation system. First of all, when the PM0.3 into the human circulatory system, the cardiovascular, brain and more An important organ harmful, resulting in a series of cardiovascular and cerebrovascular diseases, followed by mixed with formaldehyde, benzene and other organic compounds PM0.3 is also one of the chief 'culprit' of leukemia, nasal cancer, colorectal cancer, brain tumor. Not only that, PM0.3 fine particles can also cause a series of lung cancer, liver cancer, lymphoma and other cancers.This shows that the damage of PM0.3 is very huge.
How to prevent and control small particles
For small particles to solve the protective measures can be broadly divided into the following two points, the first time out to wear masks to prevent the inhalation of fine particulate matter, indoor planting some green plants to adsorb the indoor air of small particles. The second can be directly Airtight indoor use of air purifier, equipped with filter air conditioning and other purification equipment to filter out small particles.
However, for a wide range of sources and endangering PM0.3, the first method is powerless, so as technology advances, for home indoors to prevent PM2.5 / 0.3 and other small particles, the use of purification equipment are subject to More and more users of friends of all ages, among them again HEPA filter air purifier effect is the most obvious.
The above is the relevant science popularization of small particles, I believe everyone on what is the small particles (PM0.3), what are the hazards of small particles and how to prevent have a deep understanding .But only know these scientific knowledge is still not enough , The choice of appropriate protective measures is crucial.
How to prevent small particles we also mentioned that now more and more consumers prefer to use purification equipment to deal with small particles, which inside the HEPA filter air purifier with its significant purification effect to become the majority of users Friends of the first choice, so now you are only one difference from the clean air HEPA filter air purifier.
But now the air purifier market quite a mixed bag, the market is also a wide range of air purifiers, then how do we choose a number of air purifiers in a reliable HEPA filter air purifier? To solve this problem, Xiao Bian today also recommended for everyone an air purifier.
Dustie Air Purifier Sweden Dustie air purifier is the first to use a unique double-inlet fuselage structure design, coupled with the quadruple filtration system (including HEPA filter), for pollen, dust, PM2.5 / 0.3 and other small particles effective Filtration, filtration efficiency is as high as 99% .In addition its a Dustie DAC700 air purifier on the fine particulate matter filtering effect is particularly significant, of which a PM2.5 a filtration rate of up to 100%, PM0.3 of A filter rate is as high as 99% .In addition it is worth mentioning that the Dustie DAC700 air purifier also won the Swedish allergy and asthma Association's official certification recommended, is allergic, patients with history of asthma 'gospel', you can rest assured use.
So when you are still for the small particles of harmful effects on family members, in order to continue the haze affect respiratory concerns, may wish to try Sweden Dustie air purifier.It is your winter air purification perfect.
