Recently, the bad air conditions in various places have aroused the attention of all parties, and it is regarded as a "healthy guardian" market that protects the indoor environment. However, the variety of air purifiers on the market is varied, and the terminology is difficult to understand. Consumers cannot judge how the purification effect is. So, in the face of a wide range of products, how should we choose?
A look at the purification method - the composite purification method is more comprehensive
The reporter learned that the purification method is divided into three categories: passive purification, active purification and composite purification. Passive purification can only draw pollutants from the air into the machine and filter the air through the filter. Active purification can take the initiative to remove bacteria and odors from every corner of the room. The composite purification type combines the above two forms, and the purification can achieve better results.
Second, look at purification technology - give up the choice of ozone technology
Air purifiers are divided into a variety of different technologies and media, such as negative ion technology, ozone technology, and plasma ion group technology.
The main principle of negative ion technology is to use electrostatic discharge negative ions to absorb the dust in the concentrated air, which acts as a dust-reducing effect and has a certain killing effect on bacteria.
Ozone technology reacts very quickly to the inactivation of bacteria, and sterilization is thorough, but excessive ozone is a serious hazard to human health.
The "Pure Ion Group" space purification technology is a technology uniquely created by Sharp Corporation in 2000. It produces the same positive and negative ions as the natural world by plasma discharge. The net ion group consisting of positive and negative ions adheres to the surface of the floating bacteria to purify it. The effect of the air.
Third look at the filter - try to choose more than four layers of filters
The filter is the core component of the air purifier. There are many indoor environmental problems, such as odor, PM2.5, and formaldehyde. A good air purifier solves different problems through multiple filtration. The reporter visited a number of counters, the air purifier filter of each brand generally has three or four layers, like the Sharp Purifier without humidification, there are four layers of filters, and there are five layers with humidification. The first layer is a pre-filter that can filter out 500 micron particles; the second layer is a deodorizing filter that can effectively remove odors; the third layer is effective for decoration pollution and can effectively remove indoor air. Formaldehyde; the fourth layer of the screen is a HEPA filter.
Fourth, look at air purification efficiency - choose high air volume, high wind speed products
There is also a decisive factor in the effectiveness of the purification process, which is the replacement efficiency of the purifier for indoor air. The air conversion efficiency is determined by the airflow design. If you want to achieve a complete and balanced purification effect, it is best to choose the airflow guidance design with high air volume, high wind speed and oblique blowing to reduce the loss of air volume, so that the purification technology can be released to each room. The corners play to a maximum effect.
Five look at the humidification method - natural vaporization is healthier
Many humidifiers on the market use "atomization and humidification" technology. Such humidifiers generally have no sensors, and the problem of excessive humidification often occurs, even if the humidity has exceeded 60% or 70%, it will blindly humidify. Studies have shown that if the humidity is higher than 60%, it will promote the breeding of mold, bacteria, mites and the like.
Another humidification method different from "atomization humidification" is "natural vaporization". Natural vaporization releases pure water molecules closer to nature, does not produce water mist, and humidifies more evenly, which is more conducive to human health and no secondary pollution.
After-sales service is critical - after-sales service needs
The cleaning and replacement of the filter screen has a significant effect on the purification effect. Therefore, we must choose a manufacturer with perfect after-sales service. The after-sales service of major manufacturers is not the same. Sharp said to reporters that in addition to providing various after-sales services as prescribed by the state, Sharp also set up a special line of "Sharp Plasma Ion Group Purification" to provide air disinfection machines and purifiers. And use the Plasmacluster Group for technical consultation. Midea said that the current product is based on the national requirements for after-sales service specifications for household appliances, and implements the three-pack policy. Yadu said that the air purifier, the existing after-sales service network covers more than 20 provinces and cities, and can be on-site service.
Lu Jianbo, deputy secretary-general of the China Electronics Chamber of Commerce, said that the air purifiers currently on the market are mixed. Consumers should consider the purification methods, purification technology, filter screen, airflow design, humidification function and so on. In addition, it is best to choose a branded product that can provide inspection reports from third-party authorities to ensure its purification and safety. Business reporter Sun Congying
