Does a Humidifier Use a Lot Of Electricity?

Having a humidifier at your home is essential for drying air or getting rid of high humidity in the house. Apart from being much useful, these humidifiers can raise a little electricity bill depending on the use and how well it is active during the day.

Apart from that, the amount of electricity consumed may depend on the factors such as; the type of humidifier in use and the size of the room plus its efficiency.

Though at some point while considering the work done, these humidifiers electricity consumption may be neglected, at the end of the day, they make a big difference in your electricity bills. To best understand what makes a humidifier consume much electricity, we need to look at some factors.

How Much Electricity does Humidifier Use?

The amount of electricity consumed by your humidifier may differ from what someone else spends all this depending on the model of humidifies in use. There are some of the models that are electricity efficient, while others can shoot up your bills. Always when buying a humidifier take a look at the kilowatt per hour statistics to determine how much electricity you need to power it up for several hours.

Purchasing a more energy-efficient humidifier is worthy and can keep your energy bills low while still enjoying its benefits. Using an old humidifier too can pose a significant threat to your electricity bills.

It would be best if you always determined the efficiency units, the model number to discover all you want. Let us take an example of a typical humidifier with an hour rating of 280watts. Then it makes it much more comfortable in determining what the charges of using a humidifier per day are? Moreover, definitely per month on your bills?

After knowing the wattage, all you have to do now is look for the bill price of 1 kilowatt per hour and multiply by the monthly usage of kilowatts. Through this you will know the cost of electricity you will pay. Example; let’s say for each kilowatt per hour its $0.010 and you run it for 10 hours a day then means it is (10 cents x 0.28kilowatts x 10h) gives you a total of$0.28

Determining the cost of running your humidifier

In determining the cost of running a humidifier depends on the type of humidifier in use. There are three types of humidifiers as follows.

Cool mist humidifiers that preferably distributes the room moisture into the room and are much popular in use. They are likely to consume less electricity for their needs 50 watts per hour to function optimally.

Thus if we use an average of 10 cents per hour per kilowatt, then it means you are likely to spend $0.05 per day if the humidifier runs for 10 hours each day.

Warm mist humidifiers are much helpful in making the room warmer notably during winter. They heat water to a boiling point, and it vaporizes. To achieve this goal, they use 260 watts of electricity per hour, and when we have the same charges of 10 cents per kilowatt, then it means if it runs per day, it will cost you about $0.26 per day for 10 hours.

Ultrasonic humidifiers: they work the same as warm mist humidifiers, and the electrical usage will be the same.

Therefore in understanding, this will enable you to choose well which humidifier you want to use depending on the cost of running up each day and maybe a month or a year so that you can plan well.

Factors that may determine the use of electricity in a humidifier:
Apart from the types of a humidifier, other factors such as efficiency, room size, and standby mode may be of great importance in determining the consumption of power on a humidifier. Let us look at them deeper so far;


How does efficiency affect electricity consumption on a humidifier? It is dependent on the more gallons of water your humidifier is likely to put in the air.

The more useful it then means the more energy it is going to use. It mostly happens with warm mist humidifiers that may need a gallon of water to vaporize and make the air warm in the room.

For Cool mist humidifiers, they only use fans and not of much energy is needed in cooling the room. The same case applies to ultrasonic humidifies that use fans though their energy consumption is higher.

Room size

Comparing a 500 sq.Ft. House to a 1000 sq.Ft.hour then it means you need more gallons of water to make it heat your room. The size of the room matters much, and thus, the smaller space is, the faster the humidifier will work, and less energy gets consumed. The larger the room, the more the energy needed over a given period for a humidifier to achieve its results.

Standby Mode

Making your humidifier stay on always will result in increments of electricity bills. Most of the humidifiers have small electronic components such as humidity sensors and timers that too need electricity to functions. If the humidifier is on, then you can be assured that the controls that in place will consume some units. Leaving your humidifier unplugged would do a little magic to lower your energy bills.

Different humidifiers have different energy consumption; it is, therefore, one’s initiative while purchasing to determine which type of humidifier to by depending on the electricity budget in place.

So it is essential to pay attention to electricity consumption and compare the efficiency of all models in place. Humidifiers play a significant role in our lives and therefore getting the best that assures low energy consumption is essential, and if you cannot, then get help from HVAC technicians.
