Humidifier User Guide

　　In autumn, in order to avoid the discomfort of dry throat and skin tightness when getting up every morning, many consumers will choose to buy air humidifiers. But few people know that improper use can affect their own health and the lifespan of other appliances in the home. Therefore, for the purchase and use of humidifiers, the following points should be paid attention to:

　　■Type Electric heating, ultrasonic, and pure humidification From the classification of humidifiers, it can be roughly divided into three types: electric heating, ultrasonic humidification and pure humidification. Electric humidifiers achieve humidification by evaporating water through electric heating. Hot steam is easy to scald people. Due to the shortcomings of inability to dry burn and low safety factor, it has been basically eliminated in the primary market. Ultrasonic humidifiers use ultrasonic high-frequency vibration to atomize water into ultra-fine particles, and then diffuse the water mist through a pneumatic device. Its advantages are that the humidification is effective, the price is more economical, the power consumption is only 1/10 to 1/15 of the electric humidifier, and there is automatic protection without water. However, this type of humidifier has requirements for water quality, generally pure water. Pure humidification is suitable for households with hard tap water (that is, water containing more calcium and magnesium ions). This type of product removes calcium and magnesium ions from water through molecular sieve evaporation technology. However, such products are generally more expensive than ultrasonic humidifiers.

　　■ Purchase Performance comparison is very important Once you have determined the type of product you need, you should test the performance of the humidifier. Some heating equipment experts have suggested that for humidifiers that use spray form to spread water mist, the simple way to test the atomization effect is to screw the amount of mist to the middle block and observe whether the water mist is fine, transparent and rising. At this time, you can place your palm at a distance of 20 cm from the spray port, and spray continuously for 15 seconds. If you can feel the palm of your hand moist and no water droplets drip, it means that the atomization effect can meet the requirements of uniform, dense and rapid humidification.

　　■Beware of improper use, which affects health. Some health care experts said that in the dry autumn and winter, many people use humidifiers in the room all night, which may easily cause the room humidity to be too high, and induce the elderly to suffer from flu, asthma, bronchitis, etc. disease. When the general humidity is 40%RH-60%RH, people feel most comfortable, and it does not affect health. When the air humidity is 55% RH, it is difficult for germs to spread, but if the air humidity is higher than 65% RH, it will cause discomfort to the human respiratory system and mucous membranes, and reduce immunity. On the other hand, if the air humidity is lower than 20% RH, the inhalable particulate matter in the room increases, and it is easy for people to catch a cold. Therefore, using a humidifier with automatic constant humidity function can effectively avoid the problem of excessive or insufficient humidity. To maintain the most appropriate amount of humidification, you need to consider the specific conditions of the room. A humidifier with a humidification capacity of more than 270ML/H is suitable for a room of 20 square meters, and a product with a humidification capacity of 540ML/H should be selected for a room of 40 or 50 square meters.

Among them, the ultrasonic humidifier is regularly cleaned with a special humidifier cleaning solution or white vinegar. The water used should be below 40 ° C, and other types of chemicals should not be added. As for pure humidifiers, you only need to replace the evaporator and filter every one to two years.

　　The function of the humidifier is to increase the water content in the air, but it should be noted that the spray type and thermal evaporation type are useless, except for wetting the ground.
