The difference between air purifier and air disinfection machine

In recent decades, industry has developed rapidly, and environmental pollution problems have arisen, and more and more people's health has been affected. People are also paying more and more attention to the cleanliness of the atmospheric environment. New technology machines for disinfecting and sterilizing air such as air purifiers and air sterilizers have gradually entered some families. However, many consumers do not understand the principles and effects of this new technology, and worry that it will cost a lot of money to buy this new technology machine. Discuss with them today the difference and scope of application!

air purifier

Also known as "air cleaner", air freshener, refers to the ability to adsorb, decompose or convert various air pollutants (generally including dust, pollen, odor, formaldehyde and other decoration pollution) such as plaster Laozhuang plaster lamp is a kind A natural negative ion source that volatilizes negative ions called "air vitamins" to improve indoor air quality.

Air disinfection machine

An air sterilizer is a machine that sterilizes air. In addition to killing bacteria, viruses, molds, spores and other so-called sterilization, some models can also remove formaldehyde, phenol and other organic pollutants in indoor air, but also can kill or filter allergens such as pollen. At the same time, the smoke and smoke smell caused by smoking, the bad smell of the bathroom, and the body odor of the person are effectively removed.

Thereby playing the role of purifying the air, significantly improving the air quality, keeping the indoor air naturally fresh; in addition, the ozone can increase the oxygen content in the air, which can promote blood circulation, improve metabolism and prevent disease. Its usage rate is also relatively high.

According to the different sterilization methods, the current air disinfection machines on the market can be roughly divided into the following categories:

High pressure discharge ozone disinfection machine

The high-pressure discharge type ozone sterilizer manufactures a high-voltage corona electric field using a high-voltage current of a certain frequency to electrochemically react oxygen molecules in an electric field or around an electric field, thereby producing ozone. According to the high-voltage electric frequency of the generator, it can be divided into three types: power frequency (50-60Hz), intermediate frequency (400-1000Hz) and high frequency (>1000Hz). Among them, the power frequency generator is large in size and high in power consumption, and is currently rare on the market. The medium and high frequency generators have relatively small volume, low power consumption, and large ozone output, which are relatively common on the market.

Ultraviolet air disinfection machine

The ultraviolet sterilizer irradiates oxygen molecules with ultraviolet rays of a specific wavelength to decompose oxygen molecules to generate ozone. When the ultraviolet disinfection machine is working, the ultraviolet rays illuminate the bacteria in the air and microorganisms such as viruses, and the components of the DNA present in the microorganisms are destroyed, and the microorganisms such as bacteria and viruses are lost or the ability to reproduce.

Plasma air disinfection machine

The sterilization principle of the plasma air sterilizer uses a bipolar plasma electrostatic field to decompose and break the negatively charged bacteria, polarize and adsorb the dust, and then combine with the drug-impregnated activated carbon and electrostatic net and photocatalytic catalytic equipment. The secondary sterilization filtration is achieved, and a large amount of rapid circulation movement is performed through the treated clean air, so that the controlled environment is in the standard of no bacteria and no dust.

The experimental results show that the bactericidal effect of the plasma air sterilizer is fast and thorough. The sterilization rate of natural bacteria in the air reaches 100% in 30 minutes, and 99% in E. coli, Staphylococcus aureus and Candida albicans in 40 minutes. In general, plasma air disinfection and purification technology is a new technology that integrates physics, chemistry, biology and environmental science.

The air disinfection machine has a high utilization rate in hospitals and other places. It is mainly used for air disinfection in ordinary operating rooms, delivery rooms, baby rooms, supply room aseptic areas, intensive care units, laboratory, ICU and other places. Of course, in addition to hospitals, schools, kindergartens, canteens, shopping malls, libraries, nursing homes and other public places that are relatively dense and prone to cross-infection require the use of air disinfection machines.

To this end, Vision Medical has launched a plasma air sterilizer that covers three major fields, including medical, commercial, and civilian applications, and provides a full range of air purification and disinfection solutions to achieve local space bacteria, viruses, particulate matter, Control of all air parameters such as harmful gases and oxygen concentrations.
