Air sterilizers and air purifiers are common household appliances which are mainly used to improve indoor environmental quality. Although both products can improve indoor air quality, they have some differences in terms of function, working principle, application scenarios and product design.
Working Principle
The working principle of air sterilizers is to use ultraviolet light, ozone or electrolysis to produce active substances with oxidizing or bactericidal effects to achieve the purpose of disinfection. Its main advantage is that it can effectively kill viruses, bacteria and other microorganisms in the air, thus reducing the risk of indoor infectious diseases. However, air sterilizers also have some drawbacks, such as the possibility of generating foul odors, loud noise and other problems.
The working principle of air purifier, on the other hand, is to capture, decompose and adsorb airborne particles and pollutants through filters, electronic electrostatics and photocatalysts, so as to realize the effect of purifying air. The main advantage of air purifiers is that they can remove a variety of pollutants, such as PM2.5, formaldehyde and other harmful substances, and reduce odors and other problems in the air. But air purifiers also have some disadvantages, such as poor filtering effect on large particles.
Application Scenarios
Because of the above working principle and characteristics, air sterilizers are mainly used in high-risk places such as epidemic prevention and control, hospitals, nursing homes, kindergartens and other places to kill germs, viruses and other harmful microorganisms in the air. Air purifiers, on the other hand, are more suitable for homes, offices, classrooms and other densely populated places with many sources of pollution to reduce chemical pollutants, particles and other harmful substances in the air.
Product design
In terms of product design, air sterilizers usually use ultraviolet light, ozone and other technologies, which are smaller, lighter and easier to move. Air purifiers, on the other hand, are usually larger than air sanitizers, require a certain amount of space, and need to be powered by electricity or batteries. In addition, air purifiers are often equipped with multiple filters for better purification.
Safety
Air sterilizers and air purifiers are electrical products, and safety is a very important consideration. Some low-quality sterilizers and purifiers may have adverse effects on the human body, such as radiation, heat and other problems. Therefore, when buying, you need to choose products made by regular manufacturers and pay attention to check the safety certification mark of the product.
In summary, there are some differences between air sterilizers and air purifiers in terms of function, working principle, application scenarios and product design, and they each have advantages and disadvantages. Therefore, when choosing to buy, you need to make comprehensive consideration according to the actual needs, and pay attention to choose regular products in order to better improve indoor air quality.
