Why do we need an air disinfector? What are the conditions for it to be sold?

From December 2019 to the present, a new type of epidemic has been spreading globally. As of October 20, the epidemic data has a total of 125,337 confirmed cases in China and a total of 5,695 deaths; a total of 242 million confirmed cases abroad and a total of deaths 4.925 million people. So far, epidemic prevention and control have become normal, and many places in China have been defined as high-risk areas. We must wear masks for a long period of time when we travel, and subways and buses also have to take body temperature measurements and check health codes. It is not uncommon for residents in the city to have nucleic acid tests in high-risk areas where cases occur. During this period, people's demand for air disinfection machines is constantly being released, especially in public places such as major hospitals, schools, and enterprises. The demand for air disinfection machines is more urgent. However, many people may not understand the types, entry barriers and related parameters of air disinfection machines. Today I will sort them out for everyone.

First. Types of air disinfection

At present, there are three types of air disinfection machines popular on the market, including active method, fresh air method and circulation method. However, most air disinfection machines use the circulation method for air disinfection. The circulation method technology mainly includes electrostatic adsorption, HEPA filtration, ultraviolet and plasma technologies. Except for HEPA filtration, the other three are all non-consumable technologies. Among them, electrostatic adsorption can not only intercept bacteria and viruses, but also inactivate them, which is a better disinfection technology. In addition, in terms of installation methods, air disinfection machines are divided into wall-mounted, ceiling-mounted, mobile and other types.

Second. Entry threshold for air disinfection machine

An air disinfection machine is more advanced than an air purifier in that it not only has the air purification ability, but also has the air disinfection ability, and the air disinfection machine must obtain the sanitation license of the disinfection product manufacturer to enter the air disinfection machine market. If there is no relevant The permit to produce air disinfection machines is illegal production. Whether it is the provincial health administrative department or the local health administrative department above the county level, it will carry out daily supervision and management of the relevant air disinfection machine manufacturers.

Third. Filing of air disinfection machine

In addition to air disinfection products must have a sanitation license for the disinfection product manufacturer, they must also pass the sanitation safety evaluation and third-party authoritative inspections, and then apply to the health administration department for filing before they can be sold. In addition, the filing status of relevant air disinfection products can be obtained from the online platform "National Disinfection Product Online Filing Information Service Platform".

Four, air disinfection machine sales parameter description

1. The disinfection technology should be marked whether the disinfection technology is high-voltage static electricity, ultraviolet light, plasma or HEPA filtration, etc., and the parameter strength should be marked;

2. The air volume is in cubic meters per hour. The air volume of the air disinfection machine using the circulation method must be marked to facilitate the calculation of the number of cycles in the use occasion;

3. The disinfection effect. The air disinfection machine has a simulated field test before leaving the factory, and the sterilization of natural air bacteria shall not be less than 90%;

4. For the release of harmful substances, the data of ozone and ultraviolet leakage must be stated, and the internal air quality standard requirements must not be exceeded, such as ozone concentration less than 0.16mg/m3, ultraviolet leakage <5μW/cm2, etc.
