Do you know what we should know about air purification?

　　 Air purification refers to the overall solution of sterilization and disinfection, dust reduction and haze removal, removal of harmful decoration residues and odors to various indoor environmental problems, improving living and office conditions, and improving physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gas, mold, particulate matter, decoration residues, and secondhand smoke.
　　 The current main air purification technologies include negative ion technology, HEPA filter, quantitative active oxygen technology, photocatalytic technology, activated carbon, and clean room projects, Green plants, etc.
　　 Anion technology is also known as unipolar ion flow technology. The negative ion flow generated by it absorbs the positively charged suspended particles in the air, causing the particles to accumulate and become heavier, causing them to leave the gas-soluble state and settle. Negative ions have a sedimentation effect on particles with a diameter of 0.001-100 microns, but for particles less than or equal to 2.5 microns, they are called fine particles, that is, PM2.5. Only high-activity and small-sized negative oxygen ions have a significant effect. The negative ion air purifier uses the characteristic of air diffusion to fill the entire room with negative ions, which can quickly remove dust and reduce dust, leaving no dead ends, and the purification effect is more thorough. It is mostly used in small household spaces.
　　HEPA filter is divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber, which can filter particles of specific particle size. Different filters and structures can be combined into different levels of filters (primary, intermediate, effective) to meet industrial or household needs, and are widely used in purification projects and fresh air systems.
　　 Quantitative active oxygen technology and photocatalytic technology both have high technical standards, and there is a certain risk of poor control. Activated carbon and green plants have limited effect when used alone, and they are generally used in combination or topically.
　　 Regular cleaning of the filter element can extend the service life
　　Air purifiers can help consumers purify indoor air, but they also need to be cleaned up in time. Appropriate wiping and dust removal of the air outlet, air inlet and internal filter element of the purifier every half a month or a month can not only extend the service life of the filter element, but also greatly reduce the maintenance cost of the product.
　　Long-term use with electricity, avoid direct contact
The use of 　　 purifiers does not produce short-term results, but is similar to large appliances such as refrigerators and air conditioners, which require long-term use. In addition, if you use an air purifier such as electrostatic electret technology, there will be a high voltage inside it, so you need to keep a certain distance from it when you use it. Do not disassemble the machine randomly.
　　It can be placed in the center indoors for good results
　　The purifier is not a large home appliance and can be moved around the house. Therefore, it should be placed in the center of the room as much as possible during normal use, so as to purify the indoor air 360 degrees. Only placing the purifier in the corner of the room will reduce the purification.
　　 After booting, it runs in strong wind and then cleans with small wind
　　 When using an air purifier at home, it is recommended to use a large windshield 30 minutes after the machine is turned on, so that the indoor air can be filtered quickly and the indoor air quality can be quickly improved. Then gradually reduce the air volume of the purifier to prevent the noise from affecting the family's daily rest.
　　 Keep doors and windows closed and properly ventilated
　　 In use, in order to avoid outdoor dust and bacteria from affecting the indoor air, it is necessary to keep the doors and windows closed, but long-term airtightness will cause air turbidity and bacterial growth. Therefore, when the outdoor pollution is light, the windows can be properly ventilated.
my country’s air pollution has evolved from coal-smoke-type pollution in the last century to regional and compound air pollution, and has become a region with serious aerosol pollution in the world. Among them, the Beijing-Tianjin-Hebei, Yangtze River Delta, Chengdu-Chongqing, and Central Plains areas are the most important global pollution , The annual average concentration of PM2.5 has exceeded 70ug/m³, more than 2 times the standard, and more than 7 times the WHO guideline value.
On the other hand, indoor pollution has become an important threat to people’s home health. Statistics from the Environmental Protection Association show that 90% of children with leukemia have had luxurious decorations in their homes, and 2.1 million children die every year from luxurious decorations; 80% of families Decoration formaldehyde exceeds the standard; 70% of pregnant women have miscarriages related to environmental pollution; the annual death toll due to indoor environmental pollution is as high as 111,000, with an average of 304 deaths per day. Indoor environmental pollution has become one of the serious impacts on modern human health.
　　We suggest that the newly renovated house must be ventilated for a long time before moving in, and some green plants and activated carbon should be properly placed in the room, so that the new house can basically achieve a healthy living environment for about half a year. If possible, you can purchase an air purifier or install a fresh air system to continuously improve the indoor environment.
