No, this can damage the machine.
Especially in winter, when the air in our homes and our workspaces can be extra dry. A humidifier simply makes the air more humid. A person who feels dry mucous membranes has asthma, allergies, or a respiratory infection can use a humidifier. Many also experience that their mucous membranes are not as dry when they add moisture to the indoor air during the winter. If the humidity is below 40-50% RH for a long period.
When the relative humidity is below 50% RH, it is recommended to use a humidifier. Normally the relative humidity is 15-30% during late autumn and winter, so it is mainly during autumn and winter that a humidifier should be used.
In the winter, the air in our homes, and our workplace, becomes extra dry. During this season, when the outdoor air is cold, the indoor air cannot carry as much moisture. When the air is ventilated, and heated to the indoor temperature we want, the relative humidity becomes even lower. The dry air can cause itchy, dry eyes, itchy hands which can sometimes cause stinging dry cracks or cracked cuticles. But also dry sinuses and mucous membranes, which for some can lead to discomfort in the nose and throat that makes us more susceptible to viruses and bacteria. A humidifier raises the humidity in the room and reduces the inconvenience caused by dry air.
An ultrasonic humidifier has a diaphragm that breaks down the water molecules so that visible steam is blown out with the fan. Then the fog is usually at room temperature, as neither cold nor heat is added. A hybrid is usually a combination of hot and cold steam. It has a heating element in which heats the water so that the steam that comes out feels more tropical and warm.
