It is dry in autumn and winter in the north. How to improve the indoor dry environment

Dryness is the natural enemy of furniture, floors, and wallpaper. In winter, owners need to make reasonable treatment plans based on different symptoms that appear in the indoor environment to ensure a healthy and comfortable home life. Symptom 1: Increase in dust and other harmful substances Symptoms: Dust and other harmful substances in the air of Shenyang fly freely in winter. Heating will also lead to an increase in indoor sulfur dioxide, nitrogen dioxide and other harmful gases, aggravating indoor air pollution. Treatment plan: Irregular cleaning to reduce air pollution. In order to reduce indoor dust, the owner should clean the room frequently, not to mention the dead corners of the kitchen and bathroom. In addition to using a vacuum cleaner to clean the dust from every corner of the room, you also need to regularly remove dust from the surfaces of furniture, home appliances, clothing, and fabric products. Fabric sofas, carpets, and bedding are used more frequently, and there is more dust adhering to them, which can easily breed mold and mites, thus affecting the health of the owner. Therefore, the sofa should be dusted once a week. The armrests, cushions and gaps are the areas that need to be cleaned. When cleaning, you should first use a dry towel to pat away the floating dust, and then use a wet towel to wipe the cloth surface. The sofa cover should also be removed and cleaned once a year. Bedding also needs to be changed every two weeks, and bedding needs to be dried in the sun regularly for 2 to 3 hours to kill bacteria adsorbed on its surface. Symptom 2: Slow air flow Symptom: The temperature in Shenyang is low in winter. In order to keep out the cold, windows need to be closed to keep warm, so the indoor air flow is slow. However, if the indoor ventilation is poor, the carbon dioxide exhaled by the human body will accumulate indoors and cannot be discharged, thus affecting human health. Treatment plan: Regular ventilation to keep indoor air fresh Ventilation is one of the most effective ways to improve indoor air quality, because fresh outdoor air can dilute harmful gases, so owners should regularly open windows for ventilation to accelerate indoor air flow. Emphasizing ventilation does not mean opening the windows all day long. The time and number of window openings within a day can be adjusted according to the size of the room and weather conditions. Under normal circumstances, the window should be opened no less than twice a day for no less than 15 minutes each time. If the room is small, it is windy or cold outside, the window opening time should be shorter; otherwise, the window opening time should be longer; if the outside faces the road and there are more pollutants, you can open the window earlier for ventilation, and open the window earlier each time. The window time should not be too long. Symptom 3: Low indoor humidity Symptoms: The dry climate in Shenyang in winter, coupled with heating, results in relatively low indoor humidity, the floor is easily deformed, and the furniture is prone to cracks. Moreover, in a dry environment, influenza viruses can easily spread, causing pharyngitis, bronchitis, asthma and other illnesses in the owner. Treatment plan: a two-pronged approach of green plants and humidifiers National indoor air quality standards require: indoor air humidity standards in winter are 30% to 60%. The owner can place green plants in the room. Green plants themselves are humidifiers that spit out oxygen. Placing plants in different locations in the house can ensure a uniform and healthy humidification effect. If the room is larger, you can choose large-leaved subtropical plants, such as iron tree, pothos, etc.; while for smaller rooms, you should choose small plants such as clivia and spider plant. In addition, using a humidifier can also achieve the purpose of increasing indoor humidity. It is worth noting that neither ultrasonic humidifiers nor electric humidifiers can be placed too close to the human body. Because ultrasonic humidifiers emit cold mist when turned on, which can easily cause the owner to catch a cold; while electric humidifiers release hot air, which can easily burn the owner.
