As the weather gets hotter, the air conditioner, which has been idle for a year, has once again become the main electrical appliance of the family. However, if the air conditioner is not used properly, the microorganisms in it may also become a hidden killer of human health. Today, let's follow the experts from Beijing CDC to see the correct way to turn on the air conditioner. Pathogenic bacteria settling in the air conditioner Great impact on health In fact, microorganisms in air conditioners mainly come from indoor air. If we don't keep the room clean and tidy, often ventilate and clean the air conditioner regularly, then we are likely to get sick due to close contact with pathogenic bacteria. Zhang Yajie, deputy director of the Environmental Health Institute of the Municipal Center for Disease Control and prevention, said that the health status of air conditioners can have a great impact on our health. The incidents of people's health damage caused by pathogenic bacteria polluting air conditioners have spread all over the world, and have attracted the great attention of governments all over the world. For the central air-conditioning and ventilation system, China already has national health standards and strict health supervision system to ensure public health. The sanitary condition of household air conditioners requires people to improve their awareness and maintain them regularly, so as to achieve the purpose of disease prevention. Before the air conditioner is activated Remember to clean first During daily cleaning, if you open the cover of the air conditioner and remove the filter screen of the air conditioner that has been used at home for a year, you will find that it is full of dust and cotton like substances, which makes people feel particularly dirty. However, there is such a group of creatures in the world who particularly like such an environment. They are microorganisms invisible to the naked eye. Once these microorganisms occupy the air conditioning filter screen, they will seize the opportunity to rapidly reproduce on the filter screen, which is also ready for them to better enter the next position. When we turn on such an unwashed air conditioner, a large number of microorganisms are blown into the indoor air. A healthy person is knocked down by the invisibility of microorganisms after inhaling enough microorganisms to cause disease unconsciously. Therefore, it is suggested that the air conditioner should be simply cleaned before it is not reopened for a long time. Especially for the weak and sick at home, cleaning work should be strengthened. "Clearing lung" for air conditioner Immersion disinfection is the key How can I take a clean bath for the air conditioner? The steps are as follows: The first step is to cut off the power supply, wipe the outer surface of the air conditioner with a semi dry rag, then open the air conditioner panel, find the air conditioner filter screen, gently remove it, wipe the inside of the air conditioner with a dry rag, scrub the removed air conditioner filter screen with tap water, or if possible, soak it in disinfectant before brushing the air conditioner filter screen. Zhang Yajie, the deputy chief technician, introduced that the total number of bacteria on the air conditioning filter screen can be greatly reduced by washing the air conditioning filter screen directly with clean water. However, the air conditioning filter screen soaked in disinfectant can reach the degree that bacteria cannot be detected, which shows that the cleaning effect of soaking disinfectant is better. Second, the cleaned filter screen should be placed in a well ventilated place to dry, but avoid direct sunlight. The third step is to install the dry filter screen of the air conditioner into the air conditioner. Of course, when you don't use the air conditioner for a long time, you'd better put a "coat" - dust cover on the air conditioner and cover it well. It is specially reminded that while ensuring the cleanness of the air conditioner, everyone should also maintain a good hygienic environment in the air-conditioned room. Because microorganisms can be transferred between the ground, indoor air and air conditioning filter screen in the form of aerosols. (outlook new era)
