Nowadays, people pay more attention to health care. Humidifier will be placed in a dry place to increase air humidity, but humidifier must be used scientifically. Generally speaking, water is added to the humidifier. However, some people think that it is not advisable to add vinegar or Banlangen to the humidifier to prevent colds and improve immunity, and some even add perfume and disinfectant. Staying in such an exciting air environment for a long time will increase the burden on the respiratory system and cause allergies or respiratory diseases.

In 2003, the SARS virus was rampant. My parents didn't know where they heard it at that time. They put an electric stove at home and cooked some vinegar, which smelled strong all day. My brother has had asthma since he was a child, and he hasn't committed it for many years, but there was no SARS during that time, but the asthma was more serious. Never blindly listen to some folk remedies and fiddle with them yourself.
