Can a Bowl of Water Act As a Humidifier?

Can a bowl of water act as a humidifier?

Sometimes, you do not need to run the humidifier if you just want to raise the humidity slightly, say, from 45 to 50%.

If your Pure Enrichment humidifier has failed and you cannot order a new one right away, you might try a DIY method to raise the indoor humidity level.

So, can you humidify a room with a bowl of water? Placing a shallow, wide bowl of water in the center of the room can help to raise the humidity level. The bowl should be large enough depending on the size of the room or you can use several of them.

In another article, we looked at ways to humidify a room naturally. Using a bowl of water is one of the ways. So yes, it is possible to increase moisture content in the air, without using a humidifier.

How many bowls of water do you need to raise humidity?

First, you need to know how much you need to raise the humidity in your room. To know this, you should use a hygrometer. It measures the level of relative humidity indoors accurately.

If you need to raise the humidity level a great deal, you can use several bowls of water in a room, at different points. More bowls of water are going to raise the moisture content in the air faster.

You can also place the bowls around the perimeter of the room. To increase humidity, the water in the pans has to evaporate.

Evaporation is the loss of moisture to the drier surroundings in the form of water vapor. In this case, the water evaporates from the bowls to the surrounding air.

If the indoor air is too dry and you need to raise the moisture level faster, you can try to enhance the evaporation process. You can do this by placing a bowl close to the heating vents.

If you have hot water, you can pour it in the bowl and place it in the room that you want to raise the moisture level. As the steam evaporates, the humidity level is going to rise. This will do a faster job than using cold water.

Best placement for a water bowl to increase humidity

If you have high humidity outside, you could open the windows so that the humid air can flow in and help to raise indoor air moisture level.

However, most of the time, the air outside your home will be drier than what you have indoors. Keep the windows closed so that the dry air stays outside.

If you have a window that faces the sunshine, you can place the bowl of water on or close to the window. The heat from the sun will make the water evaporate faster.

At best, using this method of raising humidity in the room is slow, but it works. The important thing is to increase the rate of evaporation.

Shallow vs deep bowl for increasing humidity

The best thing here is to use a shallow bowl so that the water can evaporate faster. It is already a slow process for raising the humidity level in your indoor air. However, it can become even slower if you use a deep bowl.

Make the bowl wide and shallow. That way, most of the water is in contact with the drier air, thus increasing the rate of evaporation. A couple of hours later, you will definitely feel the change in the quality of the air in the room.

Long story short, a shallow and wider bowl will raise the humidity level easily while a deep bowl will take longer.

Raising the indoor temperature can also help

Several times in this blog, we have mentioned how warm air holds more moisture than cold air. There is a close relationship between temperature and humidity.

If the air is too dry indoors, you can use a bowl with water. To make the evaporation faster, turn on the heater. In summer, it is warmer, so that air holds more moisture. That’s why humidity is always high.

Keep checking the humidity level using a hygrometer. Do not let it exceed 50%. If it gets to 60%, mold colonies can start developing.

Can A Bowl of Water Act As A Humidifier FAQ

If you are still not sure about the effectiveness of using a bowl of water to humidify a room, here are a few frequently asked questions with more information:

Does putting a bowl of water humidify a room?

Use a wide and shallow bowl or pan as opposed to a regular bowl. That way, more of the water will be in contact with the air and it will evaporate faster, increasing humidity faster.

Will a pan of water humidify a room?

A shallow, wide pan is better at raising the humidity of a room than a deep bowl. Air is in contact with all of the water so it starts evaporating faster. The only problem is that on hot days, you might have to refill the pan more often.

How do you make a homemade humidifier?

Find a black vase and fill it to about 1/3 with water. Place it on the windowsill facing the sun. Black color retains heat so it gets hotter faster. As the water evaporates, the humidity in the room starts to rise.


Can a bowl of water act as a humidifier and be effective at increasing the level of humidity in your room. It is a slow process, so you have to be patient.
