In the winter, the indoor air is dry. In order to increase the indoor air humidity, the humidifier has become a must-have small household appliance for many citizens to survive the winter. Recently, the reporter visited several appliance stores and found that there are many kinds of humidifiers on the market, and the functions are more refurbished. The price of various brands of high, medium and low-grade humidifiers ranges from tens of yuan to several hundred yuan and thousands of yuan. Dazzling, I don't know how to choose. Inferior humidifier into a "healthy killer" Ms. Zhang bought a humidifier for 40 yuan in the wholesale market. When she tried it, she felt very good. I didn’t expect to go home for two days and the noise became very big. I couldn’t use it at night. During the visit, the reporter learned that there are many quality problems and safety hazards in the market for miscellaneous quality humidifiers: 1, the noise is large. Inferior humidifiers generate large noise during operation. 2. Most of them do not have national testing or certification. Xiao Liu, a shopping mall humidifier counter purchaser, told reporters that the inferior humidifier is blindly pursuing cost reduction. The quality of water tanks, plastic parts and electrical accessories is not good, and most of them have no national testing or certification. 3. After-sales service cannot be guaranteed. It is difficult to get after-sales service when the quality of the brand humidifier is high. Improper use of humidifiers is harmful to health If the air humidifier is not used properly, it will also endanger health. Therefore, please note the following points when using it: 1. The humidifier should not be used for 24 hours. This is because the humidifiers are used for a long time, and various bacteria are easily grown in a humid indoor environment, and these bacteria may cause numerous respiratory diseases. 2. Do not directly add tap water to the humidifier. Because the tap water contains a variety of minerals, water and alkali, it will cause damage to the evaporator of the humidifier, affecting the service life of the humidifier. Chlorine atoms, calcium and magnesium ions in tap water may be contaminated by water mist, so it is best to use pure water or boiled water. 3. The humidifier needs to be cleaned regularly. If it is not regularly cleaned, microorganisms such as mold in the humidifier enter the airway with the mist, and then enter the respiratory tract, which is likely to cause "hypertrophic pneumonia". Therefore, it is best to change the water every day, and it is best to wash it once a week. 4, arthritis, diabetes patients with caution with air humidifier. Damp air can aggravate the condition of arthritis and diabetes, so it is generally not recommended for this type of patient. 5, the most suitable humidity is the most important. Humidity is not as big as possible, and the air humidity is too high. If it exceeds 90%, it will cause discomfort to the human respiratory system and mucous membranes, and the immunity will decrease to induce influenza, asthma, bronchitis and other diseases. The general humidity is about 40% to 60%, and the human body will feel good. Therefore, it is recommended to use a humidifier at home while monitoring the humidity in the house.
