Hazards of humidifier
Indoor air humidification can be carried out by sprinkling water and placing water basin, but the most convenient way is to use humidifier. Many families buy humidifiers and turn them on 24 hours a day. However, experts pointed out that the improper use of humidifier will not only not purify the air, but also increase the possibility of suffering from respiratory diseases.
When using the humidifier, it must be cleaned regularly, otherwise the mold and other microorganisms in the humidifier enter the air with the vapor mist, and then enter the human respiratory tract, which is easy to suffer from humidifier pneumonia. In addition, the humidity of the air is not the higher the better. In winter, the humidity that the human body feels more comfortable is about 50%. If the air humidity is too high, people will feel chest tightness and dyspnea, so it is better to humidify moderately.
In order to improve the indoor dry environment, many families use humidifiers. While people enjoy the humid air, indoor bacteria also grow and propagate in such an environment. These bacteria are the main culprit causing pneumonia and respiratory diseases. This disease, which doctors call humidifier pneumonia, is similar to the common air conditioning diseases in summer. It is caused by harmful microorganisms entering the human respiratory tract through the air and causing inflammation. Once the temperature and humidity are suitable, the microorganisms floating in the air and scattered in the dust and articles will grow and multiply rapidly. The elderly and children with relatively weak resistance are easy to be infected after inhaling the bacteria. In addition to bacteria, common indoor microorganisms in winter include mold and actinomycetes, which can cause pneumonia or respiratory diseases, and phlegm cough caused by such diseases can also accelerate the spread of bacteria.
If the air humidifier is not used correctly, it will also cause certain harm to the human body. Experts remind users to pay attention to the following points when using:
1. Clean the humidifier regularly according to the instructions. If the humidifier itself is not sanitary, bacteria will float in the air with water vapor, which will also cause harm to human health.
2. Patients with arthritis and diabetes should use air humidifier carefully.
3. Adjust the humidity of the humidifier according to the weather and indoor and outdoor temperature at any time.
4. Do not add tap water directly into the humidifier.
How to choose the right humidifier
First of all, we must try our best to select some big brand products. The outlets of big brand after-sales service are set in place. Some small manufacturers only sell products, regardless of after-sales maintenance and other services, or there are few maintenance service outlets, which can not effectively guarantee the timeliness of service.
Secondly, when buying humidifier, don't be induced by sales personnel of some manufacturers. We must look at the internal structure of the product, for example, the setting of fan, the product without fan can not be called professional humidifier; whether the machine manufacturing materials are healthy and environmental protection, etc.
Third, when the humidifier product is running, it will produce a certain amount of noise. The noise itself is also a kind of auditory pollution. If the noise is too high, it will affect the normal sleep and rest. High quality humidifier, the noise will be correspondingly low. When purchasing, you can use the way of trial comparison.
Fourth, the plastic used in the case of humidifier products is also very important. In order to reduce the cost of products, some manufacturers use secondary processing plastics, which have poor quality and pollution problems. As a humidifier to improve indoor air quality, if the use of seriously polluted plastics is contrary to the original intention of the product, the harm degree may be far greater than the positive role of the product itself.
Fifth, when using humidifier, we should pay attention to the control of humidity. According to the experimental determination, when the humidity is 40% rh-60% RH, people feel most suitable and beneficial to health. Therefore, it is better to choose the humidifier with the function of automatic constant humidity. Only when the indoor humidity is lower than the standard range, the machine will start humidification. If the indoor humidity is higher than the standard range, the fog amount will be reduced to stop humidification. If the humidifier without automatic constant humidity function is used, it is better to put a hygrometer in the room to know the air humidity at any time and adjust the working condition of the humidifier according to the humidity.
Sixth, try to choose the humidifier with adjustable amount of humidification mist and bottled pure water, so as to eliminate the "white powder" phenomenon.
How to use humidifier
1. Various humidifiers have different requirements for water quality. For example, pure water should be used for pure humidifier, purified water or distilled water should be used for ultrasonic humidifier, and ordinary water should be used for electric heating humidifier.
2. When using the humidifier, the larger the humidifier is, the better. In fact, it should not be too low or too high. It should be kept between 40% RH and 60% RH. The humidification volume of the humidifier should be controlled between 300 ~ 350 ml / h.
3. The water tank, energy exchange plate and other parts that are easy to scale should be cleaned once a week. Soft cloth, soft brush and water can be used to clean the parts. It is not allowed to use detergent, kerosene, alcohol to clean the body and parts, and hard objects are not allowed to scrape the scale to avoid damaging the parts.
4. The water in the water tank of the humidifier may be used up at any time and the machine will be damaged by idling and dry burning. Therefore, try to use the products with automatic protection function of water shortage, and at the same time, pay attention to observe the water storage in the water tank at ordinary times, and give timely supplement.
5. The humidifier should be placed on the plane 0.5 ~ 1.5 m above the ground, away from heat sources and corrosion. It is strictly forbidden to touch the nozzle in order to prevent scalding. In case of any fault, it should be stopped for maintenance immediately.
Attention should also be paid to:
1. The ambient temperature is 10-40 ℃.
2. For the first time, it should be placed at room temperature for half an hour before starting.
3. Keep away from other household appliances when the machine is working.
4. Use clean water with a temperature below 40 ℃.
5. Do not place the humidifier on empty objects to avoid common frequency resonance noise.
6. Do not add non professional production line or supervised additives into water.
7. Do not start the machine without water. Ultrasonic humidifier uses transducer to convert electrical energy into mechanical energy, and generates 1.7 million times / second high-frequency oscillation through oscillation circuit, which directly vibrates water into ultrafine particles ≤ 5 μ m, and then diffuses water molecules into surrounding air through pneumatic device. When the transducer is working, its surface is easy to produce scale. If the transducer is not regularly maintained and cleaned, the load of the transducer will be increased, indicating that the machine can not work normally. It is recommended to use distilled water and purified water, which can effectively prolong the service life of the machine.
