You can check your relative humidity level using a device called a hygrometer.
It is not recommended because the humidifier may not be able to raise the relative humidity levels in an area larger than recommended to an adequate level.
A comfortable everyday humidity level should be between 40-60%.
It is recommended that you clean your humidifier weekly.

You should run your humidifier on the highest setting if your room is very dry. Once you are at a more comfortable humidity you can turn your output setting to a lower setting.
The humidifier may not be able to raise the room humidity level because it will be trying to humidify a larger area than recommended for this product.
When a humidifier is used infrequently, in very dry places or for the first time in a season, it can take quite a while for the humidity level in the room/space to rise. The reason for this is that everything in the room (walls, furniture, floors, etc) is dried out and will suck up any moisture that is in the air. Only once the items in the room or space have absorbed the needed level of moisture will the humidity level start to rise in the air.
This humidifier is equipped with a top fill feature. You can fill your humidifier using a pitcher or container of water and pouring into the funnel area located on top of your humidifier. You should stop filling when your water level reaches the "Full" tabs inside the funnel area, and/or water level in the water window is at the full mark.
