Steam vaporizers are devices that convert water into steam, which can be inhaled to help relieve respiratory issues. They work by heating water to create vapor, which can soothe irritated airways and provide moisture to dry environments. These vaporizers are often used in homes, especially during cold and flu seasons. Many steam vaporizers come with features like adjustable humidity levels and built-in filters. They are commonly used in conjunction with medications for conditions such as asthma or bronchitis. Users should ensure proper cleaning to prevent mold and bacteria growth, maintaining a safe environment for inhalation.
