This article will tell you how much does it cost to run a dehumidifier? the short answer is – The monthly cost of running a dehumidifier depends on the capacity of the unit, your home’s temperature, and humidity, and how often you run it. Generally, units with higher capacities (measured in pints per day) will cost more to operate than smaller ones.

Energy efficiency is the trend that is going along for modern homes and to maintain it, we are keeping our residences sealed-tight all the time. But as a backside, it may cause indoor humidity and there you need a dehumidifier. As it needs electricity to run,

Humidity is a common issue but when it is too high for a long period, germs and molds will start to grow. To prevent excess humidity, ventilation at home is necessary but it is a matter of question that you can sufficiently do it or not. If not, then you should go for a dehumidifier.

If you need to cover a small space, then a non-electric dehumidifier will do the job but for a large space, the electric dehumidifier is the best solution. The cost of running dehumidifiers is our concern in this article.

How Much Does It Cost to Run A Dehumidifier?

To know the answer, we’ll need to be clear about a few factors. We’ll discuss them step by step to get the right explanation.

Electric Dehumidifier How It Works?

Before heading to the brief discussion, let’s understand the working process of a dehumidifier. There is a metal surface in it that stays cool all the time. Humid air turns cold if it touches the metal surface. Water will start to condensate on the metal as the cold air contains less water than warm air.

No products found.

In it, there is a plastic bucket that catches the condensation. You can empty the bucket whenever you want. Most of the dehumidifier runs in this process but you have to take care of the efficiency before buying any.

How Long Should You Run a Dehumidifier?

Room size and humidity level – these are the two main factors that will define how often you should run the dehumidifier. If you have shifted to a new house, then you have to run it for a longer period every day as the humidity level will be high.

To prevent mold and other bacteria, a humidity level between 40 to 60 percent is recommended. If the level reaches below, then it is an opportunity for you to test different settings to adjust the level that suits your house the best.

To set the preferred levels, some best-quality dehumidifiers have timer and humidistat. For these, you have to set the level, and whenever the level is achieved it will turn off automatically. There is nothing manual in it.

Running the dehumidifier 24 hours a day will damage the internal parts and as a result, the longevity will decrease. Moreover, the cost is also an issue here. Therefore, running it 24/7 is not recommended but picking a cost-effective dehumidifier is the wisest thing to do.

What Is the Energy Star Rating in a Dehumidifier?

If a dehumidifier has an energy star rating that means it will use 20% less energy than a regular one. So, it will be efficient for you to pick a dehumidifier with a quality unit and energy star rating.

Based on capacity, the rating system divides dehumidifiers into two categories. An energy factor of 1.90 or more is needed if the capacity is <75 pints per day. For 75 and 180 pints, 2.80 is mandatory. The less, the more power consumes by a dehumidifier.

How Much Energy Does a Dehumidifier Use?

For any electric appliance, it is important to know the amount of energy it consumes and the same is for the dehumidifier of your home. How perfectly the units are using this energy is also a vital thing to know.

If you take a look at the manual or the label, you will find out the energy consumption rate of your appliance. Energy factors also indicate its efficiency.

Based on the amount of removing water per kWh, the energy factor of a dehumidifier depends. The data provided by the energy star website is also a reliable source to know about the energy factors.

You must know that the large dehumidifiers serve better than the smaller dehumidifiers. For a low-cost go, the ones with a high energy factor must not be the ideal option for you. Battery-used dehumidifiers are the best for limited space.

The Operating Cost of an Electric Dehumidifier (Approximate)

Usually, an average model dehumidifier works at 280 watts per hour. If you use it for an hour with a power rate of 15 cents/kW, the unit will use 4.2 cents in total. Now, if you keep it on for twelve hours daily, the total bill for a day will be 50.4 cents.

This whole cost idea is estimated. You might have to use it even more or much less a day. So, the numbers will vary then. The cost to run a dehumidifier for the basement will be the same as the living room. Hopefully, you have a clear idea about the operating expense of an electric dehumidifier.

How to Reduce the Cost of a Dehumidifier?

Hopefully, you have taken a look at the above energy consumption rate and operating cost. Now, you must have realized that no matter how small the size of your dehumidifier is, at the end a bill will come in front that may make you uneasy. For your convenience, there are few tips given below to help you reduce the cost.

• The Right Size: The right size means the capacity of the dehumidifier. It can be also defined as PPD (pints per day) and how perfectly it is covering the room. For optimal working, getting the right size is very important.

The first thing is where you are going to use it? Based on the size of the room, you have to choose the capacity. You can go for 50 pints or 30 pints but the challenge is to pick that covers perfectly.

• Natural Air Circulation: The more air circulates in your home, the less you need the dehumidifier. Having it does not mean that you never have to run the ceiling fans or table fans. Sometimes, nothing is better than natural wind.

The main reason for humidity is the moisture inside your house. So, if you allow a few more wind passing scopes then the inside atmosphere will be good and you can cut a share of the cost of running the dehumidifier.

• Energy-Efficient Dehumidifiers: If you want to cut the electric bill, then you should pick the energy-efficient dehumidifiers. You can save up to 20% with these. As the purchasing cost will be almost the same compared the regular models, going for the energy-efficient is the wise decision.

• Humidity Reduce: By looking after a few facts, you can reduce the humidity level of your house without the help of a dehumidifier. A bad drainage system outside your home will increase the humidity. So, you should never allow water to stay outside or do anything that creates a blockage for water passing.

Leaks in the house are one of the reasons for rising humidity. So, repairing the leaks will make you use the dehumidifier less than before.

• Use Moisture Absorber:

Desiccants or moisture absorbers are very effective. There are different sizes and models and you can choose any based on your need. If you have a dehumidifier at your home, then bringing in a small desiccant will do the job perfectly. Remember that, this is not a replacement for the dehumidifier.

• Limited Use of Dehumidifiers: When the atmosphere is cold, the refrigerant dehumidifiers will not work at their best. During the cold season, the coils take more time to heat up, and as a result, they will consume more energy than before. So, in colder months you should use the desiccants more and do not run dehumidifiers for a long time.
