Tired of always having to change the filters in your humidifier? It’s not only a pain, but it’s also not the best thing for the earth.

This is where humidifiers that don’t need a screen come in.

They are good for the environment and save you money in the long run.

In this piece, I’ll talk about filterless humidifiers and explain why they’re the best choice for people who want to save time, money, and the environment.

So, take a seat, put your feet up, and let’s talk about the benefits of filterless humidifiers.

Air Moisture and Energy Efficiency

Controlling Moisture for Energy Efficiency

Moisture can get into a building in a number of ways, like when air leaks in or when water vapor moves through the air.

Moisture control is important for saving energy because it can make a home more comfy, make it cheaper to heat and cool, and stop mold from growing.

Keeping moisture under control in a home will make air sealing and insulation work better, which in turn will help keep wetness under control.

Air Moisture and Energy Efficiency

Warm air can hold more water vapor than cold air, and when warm, wet air is cooled, it can’t hold as much water vapor, so the extra turns into liquid water.

This is what makes cold objects “sweat.” The percentage humidity of the air should be below 50% so that condensation doesn’t happen.

Moisture can also move through a home’s walls, ceilings, and floors when air and mist move through them.

This can cause mold to grow, wood to rot, or insects to move in.

Unwanted Air Flow and Energy Efficiency

Even if a building is shut off from the outside, letting in air that you don’t want can make it less energy efficient.

Moisture that moves through a building surface through the air is a much bigger and more important source than vapor diffusion.

The best way to stop wetness from being carried by the air is to make sure that air can’t get in or out of the building.

Proper insulation can also slow the flow of heat by making it harder for the heat to move.

Humidifiers for Energy Efficiency

Humidifiers use water mist or steam to add moisture to the air.

This can help people with dry throats, irritated eyes or noses, or breathing problems.

Among other things, they can help avoid the flu and cut down on snoring.

Keeping the right amount of wetness in the air is important for saving energy and making sure people are comfortable.

Moisture is a big part of how comfortable we feel, and in the winter, buildings are most comfortable when the temperature is between 68°F and 75°F and the relative humidity is between 30% and 60%.

Maintaining Optimal Humidity Levels

If you add humidity to the air, less water will escape from your body.

This can help keep the nose and throat moist.

This can be especially helpful in the dry winter months, when the cold air dries out the lungs, nose, and lips.

Too much humidity, on the other hand, can cause condensation, which can lead to mold and other problems.

Energy Star suggests keeping the humidity level inside between 30% and 40% to save energy and keep people comfortable.

Benefits of Humidifiers

Humidifiers can help with things around the house.

Houseplants that like water might get healthier, and wood floors or furniture might last longer.

Humidity can also keep wallpaper from breaking and stop static electricity from building up.

Air that is humid can also feel warmer than air that is dry.

This could help someone save money on their heating bills in the winter.

If you need to add moisture to the air, use energy-efficient methods like adiabatic (no heat) humidification, which uses much less energy and doesn’t heat the air.

Humidifiers and Energy Efficiency

Humidifiers are machines that add water vapor to the air in a room to make it less dry.

They can help ease dryness symptoms and even help with flu or cold symptoms like sore throats and stuffy noses.

People who want to save money on their energy bills and reduce their carbon footprint should get a fan that uses less energy.

Types of Humidifiers

Ultrasonic and evaporative are the two main types of humidifiers.

Ultrasonic humidifiers use high-frequency sound waves to make a very fine mist of water, which is then released into the room to add moisture.

They are quieter than evaporative humidifiers, and most of them don’t have a filter, which saves money on running costs.

Energy Star has found that cool mist or warm mist humidifiers that don’t use ultrasonic technology use more energy than ultrasonic humidifiers.

Evaporative humidifiers have been around for a long time and are thought to be the most popular type of humidifier.

They use a fan to speed up how fast water evaporates and make it more wet.

Features to Consider

There are a few important things to look for in an energy-efficient humidifier.

First, look at the power on the product information page.

A good portable humidifier that makes cool mist uses less than 30 watts.

Second, look for a humidistat.

This device tracks how humid the room is and turns on and off the humidifier as needed.

“Portable humidifiers that don’t have a humidistat will keep running until they run out of water,” says Energy Star.

Third, think about how easy it is to use, how loud it is, and how hard the water is that the humidifier puts out.

Last, decide if you just want to humidify one room or the whole house.

Choosing the Right Size

Consider the size of the room you want to use the humidifier in and the amount of humidity you want to achieve to find the right size and capacity for your needs.

When picking a humidifier, the size of the room is the most important thing to think about.

To find the right humidifier, measure the size of your room in square feet and then look at the scores, which are set up by the size of the room they are meant for.

For example, if you are using a humidifier in a small room like a bathroom or office, you won’t need as big of a humidifier as someone who is using it in a bigger room like a living room or bedroom.

Shopping for a Humidifier

When buying a humidifier, pay attention to the range of square footage listed on the box or on the product page.

That’s how big the unit is, and it will tell you if the humidifier is right for the room.

If you want to use the humidifier in a room instead of a whole floor, you should first figure out how big the room is in square feet and then choose a machine that can cover 100-200 square feet.

feet bigger than that, so that no matter what amount of moisture output you choose.

There are a lot of different kinds and sizes of humidifiers on the market, so it shouldn’t be too hard to find one that fits your needs.

You can use a humidifier sizing tool to figure out how big of a humidifier you need for your needs.

Once you know the “Load / Gallons Per Day” for your home, you can choose a steam, flow through, or drum humidifier that is made to produce the Gallons Per Day that your home needs.

You can save money on your energy bills and reduce your carbon footprint by choosing a humidifier that uses less energy and is the right size for your room.

Choosing the Right Humidifier

Maintaining Healthy Humidity Levels for Energy Efficiency

The health, comfort, and quality of indoor areas are all affected by the quality of the air inside.

The amount of wetness in the air inside has a big effect on the quality of the air inside.

Most of the time, a hygrometer is used to measure humidity and record it as relative humidity.

This is the percentage of water vapor in the air compared to the total amount of water vapor that air at a certain temperature can hold.

Effects of High Humidity Levels

Pollutants in the air can build up in places with high humidity, making the air quality worse.

Higher humidity can make materials easier to emit and speed up the rate at which they emit volatile organic chemicals.


VOCs are a group of chemicals that can hurt your health in the short and long run.

Effects of Poor Indoor Air Quality on Energy Consumption

Energy use can also be affected by the quality of the air inside.

When the air quality inside is bad, the HVAC system has to work harder to keep the temperature and humidity at a reasonable level.

This uses more energy.

For instance, if the air is too humid, the HVAC system has to work harder to get rid of the extra moisture, which can cause more energy to be used.

If the air is too dry, on the other hand, the HVAC system has to work harder to add moisture to the air, which can also use more energy.

Proper Maintenance of Humidifiers

Keeping a fan in good shape can help it use less energy and save money.

One way to keep a humidifier in good shape is to change the filter as often as the maker says, or more often if the filter is dirty.

Using distilled or demineralized water can also help keep humidifiers free of dangerous mold and bacteria, which can help bacteria grow and make deposits inside the humidifier that help bacteria grow.

Minerals in tap water can look like white dust on furniture and can be inhaled.

Keeping the area around humidifiers dry can also help keep them from getting damp or wet, which can cause people to use them less.

Humidifier Efficiency

Another thing that can help you save money and use less energy is how well your humidifier works.

The more water the humidifier puts into the air, the better it works.

So, efficiency is the amount of energy, measured in watt-hours, needed to release one gallon (or liter) of water into the air.

Because they have fans, cool mist and ultrasonic humidifiers can fill a room faster and more efficiently.

But humidifiers with hot elements use a lot more energy and can make the device cost more and use more energy.

Ultrasonic humidifiers and other technologies that work well and cost less.

Using Energy-Efficient Technologies

Using tools that save energy and money can also help save energy and money.

In the past, steam was made in server rooms with methods that used a lot of energy.

With steam canisters, liquid water is put into a cylinder with electrodes.

When power is sent to the wires, water boils and steam is made.

Using more efficient ways to add moisture to the air, such as changing the settings or buying ENERGY STAR approved humidifiers, can save a lot of energy.

For example, an ENERGY STAR-certified data center run by BNY Mellon switched its humidification set points from relative humidity to dew point.

This cut the amount of time the humidifiers ran from 80% to 20%, saving $52,000 a year and making the investment pay for itself in 1.9 years.

Ultrasonic Humidifiers: The Energy Efficient Solution

When it comes to humidifiers, ultrasonic technology is the way to go for those who prioritize energy efficiency.

Unlike traditional humidifiers that use heat to produce steam, ultrasonic humidifiers use high-frequency vibrations to turn water into a fine mist that is dispersed into the air.

This process requires significantly less energy, making ultrasonic humidifiers more cost-effective to operate and better for the environment.

Additionally, ultrasonic humidifiers are quieter and easier to maintain than their counterparts, making them a popular choice for households and offices alike.

So, if you’re looking for a way to improve the air quality in your space without breaking the bank, consider investing in an ultrasonic humidifier.

Maintaining and Optimizing Humidifiers

Types of Energy-Efficient Humidifiers

There are several ways to control the moisture in the air that use less energy than standard humidifiers. Among the choices:

  • Eco-friendly humidifiers: The EVDC3000 humidifier, for example, covers up to 750 square feet using 90% less energy than a traditional humidifier.
  • Humidifiers with humidistats: These allow you to set a chosen humidity amount, making it easy to control the amount of moisture in the air. Digital humidistats are more energy-efficient than those without.

Natural Humidity Solutions

Make a homemade humidifier out of a drinking glass, bowl, or other container, a stick, a sponge or cloth, and some water.

This is a more natural way to increase the humidity in your home.

Put a fan behind the setup and turn it down so that the water vapor can flow back into the house.

Place several homemade humidifiers around the house in a smart way.

Choosing the Right Humidifier

When buying a humidifier, you can choose between warm-mist, cool-mist, and ultrasonic models, which come in both desktop and portable sizes.

Your HVAC system can also include a whole-house humidifier.

Consider switching to an ENERGY STAR® humidifier to use less energy and get the most out of it while lowering your energy bill.

Optimizing Humidifier Settings

To find the best mix between comfort and energy efficiency when setting up your humidifier, think about the following:

  • Humidity level: Maintain a relative humidity (RH) level between 40-60% on an average annual basis and 35% during the heating season in dry climates. The EPA recommends maintaining between 30-50% humidity for the best indoor air quality.
  • Humidifier size: Ensure you buy a humidifier that is the right size for the space where it will be used. A humidifier that is too large or too small can create an imbalance in moisture levels.
  • Water source: Fill your humidifier with distilled water only to prevent irritation from inhaled minerals. Change the humidifier water often and don’t allow film or deposits to develop inside.
  • Temperature: Choose between dispersing warmer or cooler air based on your comfort preferences and the environment in which you are sleeping.
  • Maintenance: Keep the area around humidifiers dry, and clean them regularly. Follow instructions for central humidifiers if you have one built into your central heating and cooling system.

By thinking about these things, you can set your humidifier so that it gives you the most warmth while using the least amount of energy.

Smart Home Technologies for Air Moisture Control

Air Quality Monitors

Energy efficiency depends on keeping the right amount of humidity.

A meter for air quality can tell how much humidity is in the air and let you know if it is too high or too low.

The Airthings 4200 House Kit and the Amazon Smart Air Quality Monitor are two ways to keep track of the quality of the air inside on your computer, tablet, or smartphone.

Smart Home Energy Management Systems (SHEMS)

Controlling the amount of wetness in the air is another way that smart home energy management systems (SHEMS) can help save energy.

The ENERGY STAR SHEMS program recognizes smart home solutions that make it easier to use less energy, use less energy, and keep track of how much energy you use.

An ENERGY STAR SHEMS package needs, at the very least, a smart thermostat that is ENERGY STAR certified, lighting, and a way to watch and control plug loads.

The package can also include other goods and services, such as ENERGY STAR appliances, EV chargers, and smart security.

By controlling and tracking energy use in real time, SHEMS makes it easier to use energy.

This can help lower energy bills and improve energy efficiency.

Measuring Energy Consumption

The first step in making a home more energy efficient generally in terms of humidity is to measure how much energy it uses.

You can do this by hiring an energy inspector in your area or by using free tools and calculators online.

Focus on Insulation

The second step is to focus on insulation to reduce heating and cooling needs.

In new buildings, high-performance insulation and non-traditional wall systems can be used to do this.

In old buildings, air leaks can be stopped by changing doors and windows.

Use Energy-Efficient and Weatherization Upgrades

The third step is to make energy-efficient and weatherization improvements, such as adding insulation, using LED lighting, and installing a heat pump, which lowers energy use and makes the home more comfortable.

These changes can also help reduce the amount of moisture in the air by stopping moisture from building up inside the building.

Use a Ventilation System

The fourth step is to use a ventilation device to keep the air clean and stop moisture from building up.

Heat recovery ventilators are machines that use the air leaving a building to heat the air coming into the building.

Benefits of Improving Energy Efficiency

Improving a home’s energy efficiency can save money on energy bills, make the electric grid more stable and reliable, and help the environment, the neighborhood, and your health.

It is also important in the fight against climate change, since standard power plants burn fossil fuels that release greenhouse gases and add to air pollution.

Note: Please keep in mind that the estimate in this article is based on information available when it was written.

It’s just for informational purposes and shouldn’t be taken as a promise of how much things will cost.

Prices, rates, and fees can change because of things like market changes, changes in regional costs, inflation, and other unforeseen circumstances.


In conclusion, energy-efficient humidifiers are a great investment for people who want to save money on their energy bills and have less of an effect on the environment.

By not needing filters, these humidifiers save you money on repair costs and make less waste.

Plus, they work just as well, if not better, than standard humidifiers.

But let’s take a step back and ask ourselves why we even need humidifiers.

Dry air can cause problems with your face, throat, and lungs, among other things.

When you buy a humidifier that uses less energy, you not only save money and reduce waste, but you also improve your health and well-being as a whole.

So, if you already have a humidifier or are thinking about getting one, think about the long-term benefits of getting one that uses less energy and doesn’t need a filter.

You will not only be helping the earth, but you will also be making your own life better.

Take care of the earth, and she’ll take care of you, says an old proverb.
