The outbreak of the pandemic, it makes the indoor air purifier market has good prospects, and the market share continues to increase. At present, nearly 2 million excess deaths in development may be caused by indoor air pollution. About 4% of the global diseases are related to the indoor environment. Indoor air pollution has become an invisible killer for humans.
According to relevant statistics, the number of excess deaths caused by indoor air pollution in my country each year can reach 111,000, the number of excess outpatient visits is 220,000, and the number of excess emergency visits is 4.3 million.
After experiencing “soot-type” and “photochemical smog-type” pollution, human society has entered the period of the third pollution “indoor air pollution”.
According to the test results of authoritative departments in my country, the indoor air pollution in newly-decorated bedrooms and office buildings is usually 5-10 times that of outdoor air pollution, and some even reach 100 times. In undecorated and newly renovated houses, the detection rate of the main indoor pollutants formaldehyde, benzene, TVOC and other harmful gases is 100%. Formaldehyde usually exceeds the standard by 5 times, even after 6 months, it will exceed the standard by more than 3 times. . Experiments have proved that when the amount of formaldehyde released in every 100 grams of wood-based panels is 60-100 mg, it will cause obvious harm to the human body.
Relevant departments in Beijing conducted tests on 30 renovated houses and found that the concentration of formaldehyde exceeded the standard by 73%. A survey of the indoor environment of 53 new homes in Hangzhou showed that 79% of the concentration of formaldehyde exceeded the standard. Relevant departments in Shenzhen carried out sampling tests on the indoor environmental quality of 11 units and households. The results showed that only 1 household met the standards, and the other 10 had pollution problems to varying degrees. One household had 25 times the formaldehyde exceeding the standard, and the other household had a total pollution problem. Volatile organic compounds exceed the standard by more than 6 times.
Most of the building materials, furniture products and decoration materials currently used in residential and office buildings in my country contain excessive (or severely excessive) formaldehyde, benzene, ammonia, radon, chlorinated hydrocarbons and other substances that are extremely harmful to human health, which are gradually released The organic and inorganic pollutants are not discharged to the outdoors in time and decomposed indoors, resulting in deterioration of indoor air quality and increasingly serious pollution. The harm to human physical and mental health has to a large extent exceeded that of outdoor air pollution.
According to surveys, there are currently nearly 400 million people in my country suffering from indoor pollution syndromes such as asthma, allergic rhinitis, infertility, and fetal malformations to varying degrees. Poor indoor air quality is one of the main reasons. In addition, according to a recent report by the Chinese Academy of Social Sciences, the medical expenses for physical illnesses caused by air pollution in my country are estimated to be 17.1 billion yuan, and most residents in cities spend more than 80% of their time indoors. This shows that At present, my country’s indoor air pollution is in a very serious state, and its harmfulness cannot be ignored.
It can be seen that the market prospects of air purifiers are very good, whether in China or the world, and the demand for the air purification industry is also increasing. The combination of smart home and air purification is also inevitable, so as to adapt to the development of the times.
