How to choose an air sterilizer?

　　1. Qualification and Certification

　　Some people may not know that in fact, not everyone can produce air sterilizers. If they want to produce air sterilizers, they need to have a "Sanitary License for Disinfection Product Manufacturing Enterprises"; and the listing and sales of air sterilizers need to be reviewed and filed by the National Health and Family Planning Commission. In addition, it is necessary to confirm whether the relevant air sterilizer is certified, which can be inquired on the information service platform of the national disinfection product online record.

　　2. Purification and disinfection technology

　　Purification and disinfection are divided into two types: 1 is passive adsorption, which only filters and adsorbs, but does not eliminate bacteria and viruses; 2 is active killing, mainly UV, plasma, photocatalyst, etc., to actively eliminate bacteria and viruses; the air disinfection currently on the market Part of the machine is a combination of passive adsorption and active killing technologies, which can complement each other.

　　3. Look at the specific parameters and efficiency

　　According to the working principle, the larger the circulating air volume, the faster the gas circulation speed, and the larger the applicable space; the higher the filter level, the smaller the volume of particles that can be adsorbed, which can prevent bacteria from being killed. Or the cell tissue of microorganisms will cause secondary pollution to the air; the higher the efficiency of killing microorganisms in the corresponding time, the better. It is worth noting that the product must be corroborated by a corresponding third-party test report, so as to avoid being deceived.

　　4. Decibel (DB) size

　　The decibel is also the noise. When the circulating air volume is larger, the smaller the DB value, the better; if it is to be used in a resting place such as a bedroom, it should be noted that the minimum DB value under the maximum power is less than 60DB.

　　5. Cost of use and after-sale service

　　Because most air sterilizers use a filter type, the filter needs to be replaced regularly, which will result in a certain cost of use. Therefore, you can choose an air sterilizer with long filter life, low replacement cost and perfect after-sales service.
