What do you know about indoor air pollution? What role does the air purifier play?
Under the ravages of indoor air pollution, more and more indoor air problems have been reported by the media. The respiratory health problems of the whole people are at the forefront. People are paying attention to indoor air quality safety and recognizing the importance of health and the environment.
So, what are the indoor air pollution?
First, formaldehyde is mainly derived from building materials, furniture, various adhesive coatings and synthetic fabrics. Among them, mainly from wood-based panels. Formaldehyde is a volatile organic compound that has a strong pungent odor.
Second, the benzene and benzene series toluene and xylene are colorless and aromatic, and are present in the vapor state in the air. In the interior decoration, due to improper selection of decoration materials or unreasonable construction process, it is easy to form indoor benzene and benzene-based pollution.
Third, volatile organic compounds (VOCs) are mainly derived from interior materials, fuels, and the like.
First, heavy metals, heavy metals in the air are present in atmospheric particulates, while atmospheric particulates with a particle size of less than 10um contain high levels of heavy metals.
Second, gaseous inorganic pollutants have a strong pungent odor and are highly soluble in water, mainly from additives and brighteners in interior decorative materials.
Biological pollution is mainly caused by the moisture and mildew walls in the living room, domestic garbage, pets, indoor flowers, carpets, air conditioners, furniture, etc. The main pollutants are bacteria and germs.
What are the hazards of indoor air pollution to the human body?
1.Causing frequent respiratory diseases
Indoor air pollution can lead to acute and chronic changes in lung function, which can increase the filtration of respiratory symptoms, such as bronchitis and asthma.
2.Increase allergic diseases
A common symptom is allergic rhinitis. The most serious allergic disease caused by allergens and stimuli in the air is allergic asthma, which can be caused by allergens or irritants in indoor air pollutants.
Smoke, cockroaches, polycyclic aromatic hydrocarbons, asbestos, benzene and formaldehyde, and certain insecticides all have carcinogenic effects. Although the true hazard to human health is not clear, there is a potential hazard, so their concentration should be minimized in indoor air.
4.Poisoning the central nervous system
It is well known that nerve cells of the central nervous system do not have the ability to regenerate, and usually toxic damage is irreversible. Therefore, harmful substances such as formaldehyde and smog are more harmful to the central nervous system than most other tissues.
5.Endangering cardiovascular and cerebrovascular
Indoor harmful gases such as second-hand smoke and carbon monoxide can cause cardiovascular symptoms and cardiovascular diseases, leading to increased morbidity and mortality of cardiovascular diseases.
How to avoid the danger of indoor air pollution?
1.Decoration choice of environmentally friendly materials
Those who are preparing to decorate new houses pay attention to the environmental protection of interior decoration materials, because a considerable part of indoor environmental pollution is caused by improper materials used in the decoration process, such as inferior fiberboard, plywood, paint, paint, adhesive, furniture, carpet, etc. A large amount of organic gas pollutants will be released. Therefore, in the decoration process, try to use formaldehyde-free viscose, benzene-free thinner, formaldehyde-free large core board, veneer, etc., to improve the indoor air quality level after renovation.
2.Often open window ventilation
Frequent ventilation and ventilation are the most economical way to prevent indoor environmental pollution. Regardless of whether there is anyone in the house, it should be ventilated as much as possible. On the one hand, it is conducive to the discharge of indoor pollutants, and on the other hand, the toxic and harmful gases in the decoration materials can be released as soon as possible.
3.Using an air purifier
Selecting an effective indoor air purification facility, air purification devices with different functions, such as air purifiers, can be selected according to different pollutions of living room, kitchen and sanitation. The air purifier promotes the circulation of air through the ventilation system, and the air to be filtered flows into the 3-4 layer filter from the air inlet, adsorbs and decomposes the formaldehyde molecules in the air, and reduces the pollutants in the air through continuous circulation. Finally, the purpose of purifying the air is achieved.
4.Maintain a certain humidity and temperature in the indoor environment
Humidity and temperature are too high, most of the pollutants are emitted from the decoration materials quickly, which is disadvantageous when there is a person indoors, and the humidity is too high, which is beneficial to the proliferation of microorganisms such as bacteria. However, when there is no one in the house, for example, when taking a trip, some measures can be taken to increase the humidity.
In summary, indoor pollutants are diverse and can cause harm to various organs of the human body. For health, we try to choose ventilation. When it is not convenient to ventilate, we can use air purifier to remove indoor pollution and improve indoor air quality. To ensure quality of life.
