Importance of air sterilizers in COVID-19 prevention and control
Recently, with the continuous changes in the COVID-19 epidemic, the epidemic in Southeast Asian countries such as Singapore, Malaysia, Thailand and other places has shown an upward trend. Although vaccination and personal protection measures have effectively reduced the spread of the virus, airborne transmission is still a risk that cannot be ignored. In order to meet this challenge, the use of air sterilizers has become an increasingly important means of prevention and control. Today, let's discuss the necessity of air sterilizers in the fight against the COVID-19 epidemic.
1. Risk of airborne transmission of viruses
The new coronavirus is mainly transmitted through droplets, but more and more studies have shown that the risk of virus transmission in the air in the form of aerosols should not be underestimated. Especially in indoor closed environments and crowded places, the concentration of viruses in the air may be high. In this case, traditional cleaning and disinfection methods often cannot effectively remove viruses in the air. Therefore, it is particularly important to increase air disinfection measures.
2. Working principle of air sterilizer
Air sterilizers can effectively kill bacteria, viruses and other harmful substances in the air through technologies such as filtration, ultraviolet rays, negative ions or plasma. Its main working methods include:
HEPA filtration technology: Through high-efficiency filters, tiny particles in the air, including viruses and bacteria, can be removed.
Ultraviolet disinfection: Use ultraviolet lamps to destroy the DNA or RNA of the virus to achieve a sterilization effect.
Negative ion or plasma technology: By releasing negative ions or plasma, pollutants in the air are adsorbed and precipitated or decomposed.
3. Advantages of air sterilizers
Continuous disinfection: Unlike traditional disinfection methods (such as spraying disinfectants), air sterilizers can disinfect indoor air around the clock without interruption, reducing the chance of virus transmission.
Harmless and pollution-free: The disinfection method used by air sterilizers is harmless to the human body and avoids the health risks that may be caused by chemical disinfectants.
Improve indoor air quality: Air sterilizers can not only kill viruses, but also remove harmful gases, bacteria and allergens in the air, improve indoor air quality, and reduce the incidence of respiratory diseases.
4. Auxiliary tools for epidemic prevention and control
In the process of epidemic prevention and control, air sterilizers are not a tool to replace other protective measures, but work together with measures such as wearing masks, social distance, and hand washing. Especially in hospitals, public transportation, offices, schools and other places, air sterilizers can effectively reduce the airborne transmission of viruses and reduce the risk of infection.
5. Demand in Southeast Asia
Southeast Asian countries have a humid climate and a high population density, which poses a higher risk of epidemic spread. Especially in crowded cities or closed spaces, air sterilizers have become an important part of daily epidemic prevention work. With the fluctuations of the epidemic, countries have strengthened their attention to indoor air quality, and the demand for air sterilizers has risen sharply. Therefore, owning an efficient air sterilizer has become a must-have for many families and businesses.
As an efficient prevention and control tool, air sterilizers play an increasingly important role in the prevention and control of the new crown epidemic. It provides people with a safer living and working environment by continuously and stably purifying indoor air and reducing the spread of viruses in the air. In the context of the global fight against the epidemic, we should fully realize the importance of air sterilizers and actively adopt this prevention and control measure to contribute to controlling the epidemic and protecting public health.
