In autumn, many consumers decide to buy a humidifier to avoid unpleasant sensations such as dry throat and tight skin after waking up every morning. However, few people know that improper use can affect their health and the lifespan of other household appliances in their home. Therefore, when buying and using a humidifier, pay attention to the following points:
type
According to the classification, ultrasonic air humidifier can be roughly divided into three types: electric heating, ultrasonic humidification and pure humidification. Electric humidifiers humidify by evaporating moisture with electric heating. Hot steam burns easily. Due to the impossibility of dry burning and the low safety factor, it is basically excluded from the primary market.
Ultrasonic humidifiers use ultrasonic high-frequency vibrations to disperse water into ultrafine particles and disperse water mist through a pneumatic device. It has advantages such as high humidification performance, low cost, 1/10 to 1/15 input power of electric humidifier and automatic waterless protection. However, this type of humidifier has water quality requirements, usually clean water, otherwise scale may appear.
Pure humidification is suitable for households with hard water (ie water with a high content of calcium and magnesium ions). This type of product removes calcium and magnesium ions from water using molecular sieve evaporation technology. However, such products are generally about 200 yuan more expensive than ultrasonic humidifiers.

Performance comparison is important
Once you've decided on the type of product you need, test the effectiveness of your humidifier. Some heating equipment experts believe that for humidifiers that use a spray form to spray water mist, an easy way to test the spray effect is to screw the amount of mist into the central block, and the amount of water mist is recommended to observe whether it is fine, transparent and growing. During this time, keep your palm at a distance of 20 cm from the spray nozzle and spray continuously for 15 seconds. If you feel that your palms are moist and do not drip water droplets, it means that the spray effect can meet the requirements of uniform, dense and fast hydration. A certain amount of noise is generated during the use of the humidifier. Too much noise disturbs normal sleep and rest.
A humidifier with automatic humidity control is also recommended. A humidifier that automatically turns on and off according to the humidity preset by the user to keep the humidity constant.

Beware of improper use that affects your health
Some health experts say that during the dry fall and winter seasons, when many people use humidifiers in their rooms all night, the humidity in their rooms can be too high, which can lead to flu, asthma and other diseases in the elderly. states that it is possible to get diseases like bronchitis.
General humidity is most comfortable between 40% RH and 60% RH, which does not affect your health. When the humidity is 55% RH, it is difficult for bacteria to multiply, but when the humidity exceeds 65% RH, it causes discomfort in the respiratory system and mucous membranes of humans and weakens the immune system. On the other hand, if the humidity is lower than 20% relative humidity, the amount of particles that can be inhaled indoors will increase, making people more susceptible to colds. Therefore, by using a humidifier with an automatic constant humidity function, you can effectively avoid problems with excessive and insufficient humidity.
To maintain optimal humidity, the specific conditions in the room must be taken into account. A humidifier with a humidifying capacity of 270 ML/H or more is suitable for a room of 20 square meters, and a product with a humidifying capacity of 540 ML/H should be selected for a room of 40 or 50 square meters. square meters.
In addition, change the water in the humidifier daily and preferably clean it once a week to prevent the spread of microorganisms from the water into the air. Among them, it is best to regularly clean the ultrasonic humidifier with humidifier cleaning solution or white vinegar. Use water up to 40°C and do not add other chemicals. As for clean humidifiers, you only need to replace the vaporizer and filter once every one to two years.
