"Humidifier pneumonia" You can't blame the humidifier
Humidifier can indeed relieve the discomfort caused by dry indoor air and low humidity. However, if is used improperly, it may also cause respiratory diseases in our bodies, which is medically called "humidifier pneumonia". This is because harmful microorganisms enter the human respiratory tract after being atomized by a humidifier and triggers a series of respiratory diseases caused by inflammation, such as colds, bronchitis , asthma, etc. Common symptoms are nasal congestion, cough, phlegm, asthma, fever, etc.

In fact, the existence of "humidifier pneumonia" is not the fault of the humidifier itself, but the improper use of the humidifier, such as:
1) Humidifier is not cleaned in time, so it is easy for 1 to absorb and breed bacteria and viruses. then passes through the humidifier and turns into a bacteria-containing mist and is inhaled into the respiratory tract, thereby causing various respiratory diseases.
2) Humidification for too long, causing excessive air humidity. is conducive to the growth of bacteria and viruses in the air, entering the lungs with breathing, causing respiratory symptoms.
3) The humidifier uses a humidifier with poor water quality and contains bacterial viruses, etc. passes through the humidifier to form bacterial water mist and inhales into the lungs, which may also lead to a series of respiratory diseases.
these people It is not recommended to use humidifier
In addition to the use method, we do not recommend using humidifiers for the following groups due to special physical conditions and physical conditions:
1) People with rheumatism and rheumatoid arthritis should use humidifier with caution, because humidifiers will increase humidity in the air and easily induce the onset of such diseases.
2) People with chronic lung disease , such as bronchitis, asthma, COPD , etc., need to be used with caution, because improper use of humidifiers can easily induce the onset of such respiratory diseases.

3) The elderly and children should be used with caution, because the elderly and children have poor respiratory mucosa resistance and high air humidity, which is easy to breed bacteria, viruses and other respiratory diseases.
Master the correct method. Use the humidifier well.
In addition to the above people, when the air is turned on for a long time and when the air is dry after heating in winter, you can use a humidifier to improve the air humidity and alleviate and avoid discomfort such as skin dehydration, dry mouth and tongue.It is only when using it, pay attention to good methods to avoid the "side effects" it brings while utilizing the advantages of humidifier:
1) Generally speaking, keeping the air humidity at 40%-60% is a relatively comfortable state. You can prepare an hygrometer at home, and then adjust and use the humidifier according to the specific situation of the day to keep the room within the appropriate humidity range.
2) There are also some considerations for the location of the humidifier: first, you must stay away from the power socket at home, and it is best to place it at a height of about one meter from the ground. This is not only safe, but also more conducive to the distribution of water mist generated by the humidifier and balance humidity.

3) The water in the humidifier should be replaced every day. cannot use tap water. It is generally recommended to use pure water to avoid the bacteria in the tap water spreading into the air through the water mist in the humidifier, causing respiratory diseases.
4) Do not add vinegar, essential oil, perfume , etc. to the humidifier. These ingredients are atomized and inhaled into the lungs, which can easily induce allergic rhinitis or asthma.
5) The humidifier must be kept clean. Generally, it is necessary to clean the humidifier once after about 3 days: first soak and disinfect with hot water, then rinse with running water, and finally wipe off the scale with a clean cloth. Also, be careful that the small grooves in the humidifier should be cleaned as much as possible.
6) If you are idle for a long time, be sure to pour out the wastewater, air-dry the water tank, and store it for later use.

Most products are first in demand before they will be developed and produced, and enter our daily life with their own mission. As for its use effect, it must be comprehensively judged based on whether the usage method is reasonable. If it really cannot be used, or the harm outweighs the benefits, it will naturally be continuously upgraded and optimized, or directly eliminated by the market. What we need to do is to make rational use of all the tools around us to make our living environment more comfortable and beautiful.
