Improper use may lead to diseases.

The reporter learned from several major hospitals that the daily outpatient volume of respiratory department has tripled than usual. According to the doctor, since the winter, the incidence of influenza, asthma, bronchitis and other diseases has increased significantly, which is closely related to the dry climate and the increase of inhalable particles. However, some patients get sick because of improper daily use of humidifiers.

In this regard, the reporter consulted some experts. A person in charge of Duya humidifier said that when using the humidifier, the indoor humidity should be controlled well, and the healthy humidity environment is 45%-65%. Under such humidity conditions, the human body feels most comfortable, and various germs are not easy to spread. When the humidity is higher than 65%, it will make the human respiratory system and mucous membrane uncomfortable, and the immunity will decrease, leading to the virus taking advantage of it. He reminded that the use of humidifiers should not be lazy, and the water should be cleaned and replaced every day, otherwise the microorganisms produced in the water will also affect health when discharged into the air. In addition, room ventilation is also very important. Only regular ventilation can effectively prevent respiratory diseases.

Humidification phenomenon

The problem of "white powder" puzzles consumers

At present, the price of ultrasonic humidifier ranges from 100 yuan to 500 yuan, which is a low-end product with low technology content, accounting for more than 80% of the whole humidifier market share. Although the price is cheap, it is not easy to use ultrasonic humidifier in Beijing. Families who use humidifiers often find that furniture and household appliances are covered with a layer of "white powder" after getting up in the morning, which is very troublesome to wipe, and may cause wear and tear on the surfaces of furniture and household appliances for a long time.

Experts say that this is caused by the ultrasonic humidifier atomizing water into ultrafine particles of 1-5 microns through the high-frequency oscillation of the water mist generator, and then diffusing the water mist into the air. Because the mineral content of tap water in Beijing reaches 24 mg per liter, which is 3 to 4 times higher than that of most cities in the south and 10 times higher than the foreign drinking water standard. Ultrasonic humidifier sprays water mist into the air, and also brings minerals from tap water into the air, which is called "white powder".

Wen Hui, executive deputy general manager of Duya Humidifier Company, told reporters that the solution to this problem is to clean the smoke machine regularly, usually once every half a month to once a month. If you find it troublesome to clean the machine, you can also pour pure water or cold boiled water below 40℃ into the machine, which can reduce the appearance of "white powder" to some extent.

Humidifier beauty

Water mist beauty has no scientific basis.

In an electronics store, the salesperson told the reporter that the "water mist" humidifier can have the functions of automatic humidity balance and automatic protection without water, and can replenish water and beautify the skin.

For this theory of hydrating, Dr. Chen from beijing jishuitan hospital Dermatology Department believes that hydrating the skin can only be done from the inside out. Because the skin has a protective film, it is impossible for water to penetrate into the skin from the outside. The "skin hydration" that the beauty industry has been talking about is actually just "skin moisture protection". "How does a humidifier replenish moisture to the skin from the outside?" Dr. Chen expressed doubts.

Humidifier investigation

Seven adults don't know how to use it correctly.

Yesterday (65438+February 65438+March), the reporter interviewed 20 people at random (8 males and 8 females 12), 9 of whom had humidifiers at home and 7 used them frequently. But no one can correctly answer the question "how to prevent the ultrasonic humidifier from producing white powder". Only one person knows that the purifying humidifier needs to spend extra money to replace the core every year. The reporter also found that among the six women who have humidifiers at home, five have used the water mist of humidifiers for beauty experience.

In such a simple random survey, the reporter found that many consumers don't really know about humidifiers, and there are many incorrect places in use.

Tips for purchasing humidifier

There are many kinds of humidifiers, each with its own advantages and disadvantages, so how to choose?

1, depending on the regional water quality. It does not matter which water quality is good; If the water quality is poor or the air quality in the room that needs humidification is poor, pure electricity or electric heating should be chosen.

2. Follow your heart. If you like the dreamy feeling of being in a fairyland with a slow mist, then choose ultrasonic spray; If you like refreshing and hate foggy feeling, pure style is the ideal choice.

3, the water tank must be carefully selected. When selecting, you should carefully observe whether the appearance and interior of the water tank are in good condition and whether the capacity of the water tank can meet your own needs. The water tank is too small, so we have to get up in the middle of the night to add water. The water tank is too big and the water is stored for a long time, which is easy to cause "secondary pollution".

4. The service life of humidifier is related to the core component-oscillating plate. At present, the high-quality oscillators on the market can be used for 4000-6000 hours, the ordinary life is below 3000 hours, and the inferior oscillators can only be used for hundreds of hours.

5. After-sales service should not be underestimated. When buying, you must choose the brand of a professional manufacturer. Du Ya, Aipu, Alan in China and Jerry abroad are all good.

■ correlation

Three types of humidifiers dominate the market.

Although there are various humidifiers on the market now, they can be classified into three categories:

1. ultrasonic humidifier: water is atomized into ultrafine particles of 1-5 microns by ultrasonic high-frequency oscillation, and the water mist is diffused into the air by pneumatic device, thus achieving the purpose of humidifying the air evenly.

Advantages: high humidification intensity, uniform humidification, high humidification efficiency, power saving and long service life, which has been deeply loved by consumers. The disadvantage is that it requires high water quality. If the water quality is hard, there will be white powder and scale, and the white powder will cause some damage to furniture and household appliances.

2. Pure humidifier: Pure humidification technology is a high-tech in the field of humidification today. It uses molecular selective volatilization technology to remove impurities in water, and sends pure water molecules into the air through pneumatic devices to achieve the purpose of humidifying the air.

Advantages: no requirement for water quality, no white powder phenomenon, no scaling after humidification, especially suitable for poor water quality in North China. In addition, it also has a certain role in purifying the air. Disadvantages are relatively loud noise and high price.

3. Electric humidifier: it is the simplest humidification method in technology. It uses a heater to heat water to the boiling point, generating steam and releasing it into the air for humidification.

Advantages: large amount of humidification, no requirement for water quality, no white powder and low price. Disadvantages are high power consumption, no dry burning, low safety factor and easy scaling on humidifier.

How to use humidifier correctly

Humidifier is a small household appliance often used in winter. It is very important to use it correctly if you want to fulfill your duties and serve for a long time.

1, preferably placed on a stable plane of 0.5- 1.5 meters, away from heat sources, corrosive substances and furniture, and away from direct sunlight.

2. Don't use empty boxes. When moving, drain the water in the water tank and don't turn it upside down. Don't use it in the frozen state, you should use clean water below 40℃.

3. It is best to use special humidifier cleaning solution or white vinegar to clean the ultrasonic humidifier regularly. The electric humidifier needs to clean the scale in the water tank regularly. The pure humidifier is easy to maintain, just change the evaporator and filter every 1-2 years.

Note: Do not put the machine into water when cleaning; The cleaning water temperature shall not exceed 50℃; Don't scrape off the scale with hard objects, and don't clean the fuselage and parts with detergent, kerosene and alcohol to avoid damaging the parts.

4. When the humidifier is not used for a long time, the residual water in the sink and water tank should be poured out, and all parts should be cleaned, dried and then put into the original packaging box for collection.
