What is the difference between an air purifier and a medical air disinfection machine?

Air purifiers and air disinfectors are two different appliances. They both aim to improve indoor air quality, but their specific working principles and functions are different. Here are the differences between them:

working principle

Air disinfection machines usually use technologies such as ultraviolet light, ozone or electrolysis to release active substances that can sterilize and disinfect, in order to kill bacteria, viruses and other microorganisms in the air.

The air purifier mainly captures, decomposes, and adsorbs particles and pollutants in the air through filters, electronic static electricity, photocatalysts, etc., thereby removing odors, PM2.5 and other pollutants in the indoor air to achieve purification. Air effect.


The main function of the air disinfection machine is to kill harmful microorganisms such as bacteria and viruses in the air to achieve disinfection, deodorization and other effects. Therefore, it is widely used in hospitals, kindergartens, nursing homes and other places as well as in some families to ensure people’s health and safety.

The main function of an air purifier is to remove harmful substances in the air, such as PM2.5, formaldehyde and other harmful substances, while reducing indoor odors to improve indoor air quality. Therefore, it is usually used in homes, offices, classrooms and other places where air purification is required.

Design and use

Since the air sterilizer mainly targets microorganisms, it can usually be conveniently placed in various places, including tables, floors, walls, etc.

Air purifiers require a relatively fixed location and usually require electricity or battery power, so they are slightly inferior to air disinfection machines in terms of mobility.

Application scenarios

Air disinfection machines are mainly used in high-risk places such as hospitals, kindergartens, nursing homes, and some homes to kill harmful microorganisms such as bacteria and viruses in the air, thereby ensuring people’s health and safety.

Air purifiers are more suitable for homes, offices, classrooms and other places with densely populated areas and many pollution sources to remove harmful substances such as particulate matter and odors from indoor air to improve indoor air quality.

In short, air purifiers and air disinfectors are different in terms of working principles, functions, designs and application scenarios. When choosing to purchase, you need to make comprehensive considerations based on actual needs and choose products that meet standards to achieve better air purification or disinfection effects.
