Recently, many places in the country have encountered smog weather. On November 26, Zhang Ziyi sent Weibo to say that Beijing was heavily smoggy. Her daughter would not breathe when she wears a mask. She worried about her child’s health and immediately took the plane and left Beijing. In this weather, parents will worry about their children’s health. They want to leave the cities with serious air pollution and work and live in the clean, fresh air. However, in real life, you can do it. How many people can there be? Most people are not so chic, they can only “squat” to stay in the city of gray and continue to live. Since you can’t walk, how should everyone protect themselves? Especially how to protect children? There are many harmful substances in foggy days. Children with allergic asthma and allergic rhinitis should pay more attention to this kind of weather. When exposed to polluted air, the respiratory tract is stimulated, it is easy to aggravate respiratory symptoms, so we must make good precautions in advance: minimize the outing, reduce strenuous exercise, be sure to wear professional masks, clean the indoor air when going out, and protect indoors. Air quality; adults should take off their coats when they go home, wash their hands and then touch the children, try to avoid all behaviors that can directly harm the child’s health. The smog has come again, what we can do is to prevent it and protect the breathing and health of ourselves and our family. Nowadays more and more people use air purifiers, but the air purifier products are slightly stranger to ordinary consumers. In daily use, we should pay attention to avoid the following seven misunderstandings – Misunderstanding 1: Air purifier is placed against the wall I believe that after many consumers purchase an air purifier, most users will place it against the wall. What you don’t know is that in order to achieve the desired whole house purification effect, the air purifier should be placed away from the wall or furniture, preferably in the center of the house or at least 1.5 to 2 meters away from the wall. Otherwise, the airflow generated by the purifier will be blocked, resulting in a smaller purification range and worse performance. In addition, placing against the wall will also absorb the dirt hidden in the corner, affecting the life of the purifier. Misunderstanding 2: The distance between the purifier and the person is too close When the purifier is working, there are more harmful gases around it. Therefore, do not place it too close to people. It should be properly raised to avoid contact with children. An electrostatic adsorption type purifier that allows airborne contaminants to adhere to the electrode plates during operation. However, if the design is not reasonable enough, a small amount of ozone will be released, and more than a certain amount will stimulate the respiratory system. When using this purifier, it is best not to stay in the room, and to close it after entering the house, because ozone can be quickly restored in space and will not remain for a long time. Misunderstanding 3: Change the filter from time to time Just like the mask is dirty, you have to change it. The filter of the air purifier should also be replaced in time. Even in the case of good air quality, the filter screen should be replaced more in a while, otherwise, the filter material will release harmful substances after being saturated, and instead become a “source of pollution”. Therefore, it is necessary to regularly maintain the product and replace the filter. Misunderstanding 4: Put the humidifier next to the purifier Many friends have both humidifiers and air purifiers in their homes. Many users use air purifiers and turn on the humidifier at the same time. In fact, it has been found that if the humidifier is placed next to the air purifier, the indicator light of the purifier will be alarmed, and the air quality index will rise rapidly. It seems that the two will interfere with each other. If the humidifier is not pure water, but tap water, since tap water contains more minerals and impurities, chlorine molecules and microorganisms in the water may be blown into the air with the mist sprayed from the humidifier to form a source of pollution. If the tap water has a high hardness, the water mist may have white powder, which may also pollute the indoor air. Therefore, it is recommended that you use pure water if you use a humidifier. If using tap water, it is recommended to keep enough distance with the air purifier. Misunderstanding 5: Usually not used, smog genius open purifier The prevalence of air purifiers is caused by persistent haze weather. However, we also mentioned above that for the cleaning of air, not only the smog is pollution, dust, odor, bacteria, chemical gases, etc. all have adverse effects on the human body, and the role of the air purifier is positive. It is the removal of these harmful pollutants. Especially for the newly renovated homes, the vulnerable people who are sensitive to air, such as the elderly, children and so on, the air purifier can still play a role. Of course, if the weather is fine outside, it is recommended that everyone’s indoors be ventilated and maintain a certain humidity so that fresh air can flow indoors. Sometimes such indoor air quality is clearer than that of an air purifier that is open all year round. Misunderstanding 6: Air purifier shows excellent time, no need The power consumption of air purifiers is generally not high, and the power consumption of mainstream products generally does not exceed 70W, which is still very power-saving. When the air quality is poor, when using the purifier to see the display shows excellent air quality, please do not turn off the purifier immediately. It is recommended to turn it off again for 1~2 hours. Misunderstanding 7: When opening the air purifier, do not close the door and window For indoor pollution control, there are many factors influencing the source of pollution, and it is not only based on air purifiers. For example, in Beijing where smog is frequent, if there is continuous smog, first close the window, open the door as little as possible, and create a relatively closed space for the indoor battalion; secondly, adjust the indoor temperature and humidity conditions, and pass the humidifier and water in winter. The method will increase the relative humidity and prevent the room from dusting. It is more effective to use an air purifier under such circumstances. Otherwise, the source of pollution will continue to come through the window, even if the air purifier is always on, the effect will be greatly reduced.
