How to Get the Best Warm Mist Humidifier

Family in Room with Modern Air Humidifier

A humidifier consists of different parts, and there are also numerous models on the market. There are a few things you should know before purchasing one of these humidifiers. We’ll take a quick look at some of them. 

The Type

The first and most important thing you should check is the type of humidifier you’re getting.

The common types of humidifiers are warm mist and cool mist humidifiers. There are individual brands that make each type, and there are some that make a combination of both.

The warm mist humidifier is great for the cold seasons like winter when you want your room to be warm and cozy. The warm mist humidifier produces warm mist and keeps your room at a suitable temperature. 

On the other hand, the cool mist humidifier is designed to produce cool air. The cool mist humidifier is designed for hot periods like summer, and they don’t require much energy compared to warm air humidifiers. 

Also, some brands of humidifiers can produce both warm and cool mist, such as some of the products we reviewed above. When picking a humidifier, we recommend you choose one that can produce cool and warm mist.

If you select one that only produces one mist type, you will need to spend extra when the season changes. However, if your humidifier can dispense warm and cool mist, you don’t have to worry about spending extra. 

Tank Capacity 

From the product descriptions we’ve provided earlier, you can see that there are different sizes of humidifier tanks. The tank is a very important component of the humidifier, and it decides the amount of water it can hold at a time. 

The tank capacity also plays a huge role in deciding how long the device will last before a refill and the size of the room it can cover. These are some things you must consider along with the tank capacity. 

Some common tank capacities include six liters, one gallon, and two gallons. The capacity can also be classified into large, medium, and small tanks. 

If you plan to use the humidifier in a small room, you can get a device with a small tank that won’t take a lot of space. One-gallon humidifiers are a good choice for small to medium rooms and will be very effective. 

If the room is large, you will need a humidifier with a large tank capacity. We recommend going for a humidifier with six liters or two gallons. 

Ease of Use 

The ease of use refers to how comfortable you are using the humidifier and different factors determine the ease of use. Some of these factors include:


The refill is part of the factors determining the humidifier’s ease of use. You will want to get a humidifier that is easy to refill within a short time. The time it takes to refill the device is based on the tank’s design. 

Some tanks have a top-fill design that features a large opening at the top. To refill this type of humidifier, all you need to do is open the top and pour water until the tank is full. 

There are also detachable tanks, and these tanks need to be removed before you can refill them. To remove a detachable tank, you will need to twist and turn different parts, which can take some time. 

Some tanks are both top-fill and detachable. You can choose these types because they are easier to refill and clean. 


Another factor to consider under ease of use is cleaning. You don’t want a humidifier that will stress you out when it’s time to clean. The main part that requires cleaning is the tank. 

Humidifiers with detachable tanks are easier to clean and maintain. You can easily remove the tank from the rest of the device and wash them separately and thoroughly. Humidifiers with undetachable tanks are harder to clean and require more caution when handling. 

It is better to go for a humidifier with a detachable tank and a top-fill design. Humidifiers like that are easy to refill via the top-fill system, and you can easily wash the tank by detaching them from the humidifier. 


The filter is another important component of the humidifier and is responsible for producing clean mist. There are different types of humidifier filters, each with advantages and disadvantages. 

Long-lasting filters are designed to be used for extended periods, and you hardly need to change them. The ceramic filter is an example of a long-lasting filter, and you can see the application in some of the products we’ve listed. 

Some filters need to be changed frequently to achieve the desired results. Humidifiers with these short-lived filters are less expensive than those with longer-lasting filters and are easier to find. 

On the other hand, humidifiers with filters requiring constant replacement pose a lot of work to maintain. You need to get filters frequently and open your humidifiers. However, the long-lasting humidifiers don’t need much maintenance, and you can keep using them for a long time. 

Another type of humidifier doesn’t require a filter, and we call these filter-free humidifiers. Filter-free humidifiers have nozzles designed to act as filters, and some come with disinfectant additives. 

We recommend long-lasting filters or filter-free humidifiers. They require less stress and are easy to maintain. 

Noise and Energy Consumption 

Many people overlook this, but noise and energy consumption are factors that should be considered.

We’ve encountered some humidifiers that give out a lot of noise due to fan rotation and other working components. We’ve also seen some devices operating without much sound or noise. 

When getting a humidifier, it is best to go for one that hardly makes noise. A noisy humidifier can be very annoying, especially when you need to sleep or in the middle of the night. We recommend that you test the product before making a purchase and ensure it isn’t loud.

Energy consumption is another key factor. You don’t want to get a humidifier that consumes more power than you can afford. Before buying the product, check the specifications on the pack for the power rating and other relevant information. 

Moisture Output 

The moisture output refers to the amount of moisture released per time. You need to check the moisture output because it will determine how fast it will take for the whole room to be humidified.

The moisture output works hand in hand with the size of the room. Before you get any product, have an estimate of the room size and use it to determine the moisture output that will be effective. 

If you want to use the humidifier for a large room, it is better to go for a product with a high moisture output. A high moisture output will ensure the mist circulates the space faster and save you energy consumption. If you use a humidifier with low moisture output for a large room, it will take a long time for the mist to diffuse and consume more power. 

If you’re planning to use the humidifier for a small space, one with a low moisture output should suffice. Although the output is low, the humid mist will still travel around the room faster because of its small size. Getting a device with high moisture output for a small room would be wasteful. 

You can check the moisture output of the desired product on the package. It should be listed with other useful information. 


Runtime is the amount of time the humidifier can work before needing the next refill. 

The runtime is largely determined by the tank capacity and the moisture output. It is best to go for a product with a long runtime since it will save you the stress of refilling the tank after short intervals. 

We recommend getting a humidifier with a runtime of up to 48 hours. We’ve seen some products that boast a runtime of up to 100 hours. If you want a humidifier with a long runtime, look at the tank capacity and the output. 

Humidifiers with larger tanks are capable of lasting longer because they can hold more water. However, you can adjust the moisture output for a longer runtime. The runtime will be longer if the device has a large tank of about six liters and the moisture output is high.

You can still enjoy a long runtime if the tank capacity is low. In this case, we recommend you reduce the moisture output to the lowest setting to ensure that your humidifier lasts longer. 

Room Size 

The room size also goes a long way in determining the type of humidifier you buy. The humidifier you get should be able to circulate the room in a short time and without consuming too much power. 

You must know the room size to get a humidifier. Large rooms require devices with large capacity and output. Smaller rooms don’t need a humidifier with a large tank capacity. You can use a medium or low output humidifier in a smaller room.

Night Mode 

Night mode is a feature that facilitates a better sleeping experience when using the humidifier.

Night mode turns off all the humidifier’s lights and reduces the noise produced in some models. We advise that you go for a brand that offers night mode because it will make it easy for you to sleep with the humidifier running. 

Some products don’t come with a night mode, especially with some older versions. If you’re not easily disturbed when sleeping, you can use a humidifier without night mode. If you’re a light sleeper, we recommend you get a humidifier with night mode. 

Humidifiers with night mode are great for a kid’s room or nursery. You won’t have to worry about the humidifier waking up small children.


Some new models of humidifiers come with timers, and the humidifier automatically shuts off after the timer runs out. This timer feature saves energy and ensures that your humidifier gets some rest. 

It is advisable to go for a product with a timer because it will save you a lot of energy and is also good for the maintenance of the humidifier. 

Cool Mist vs. Warm Mist Humidifiers 

Cool Mist vs. Warm Mist Humidifiers

Cool and warm humidifiers both produce mist, but what is the difference between these two products? 

The Air Produced 

Cool air humidifiers are designed to produce cool air and are suitable for warm seasons or dry seasons. On the other hand, the warm mist humidifiers produce warm mist and are suitable for colder seasons. 

Mode of Operation 

The function of the warm mist humidifier is to release warm, moist air and raise the room’s temperature to a certain degree. For the warm mist device to operate, it needs to warm the water in the tank before dispensing. 

The warm mist humidifier is designed with a heating element. The heating element is the key component that raises the temperature of the water. The heated water is dispersed as steam or warm mist around the room. 

On the other hand, the cool mist humidifier comes with a fan. The fan is the component responsible for cooling the water and circulating it into the air. 

We can see the difference in the mode of operation from the explanation provided above: warm mist humidifiers use a heating element while cold mist humidifiers use a fan. 

Energy Consumption 

From the mode of operation, there is another difference: energy consumption. Warm air humidifiers tend to use more energy than cold air humidifiers, and this is due to their mode of operation. 

Warm air humidifiers use a heating element, which needs to raise the temperature of the water. All these effects cause the warm mist humidifiers to consume much more energy and have a higher power rating. 

On the other hand, the cool mist humidifier uses a fan to cool air and circulate cool moisture around the room. The cool air humidifier doesn’t use as much energy as the warm air humidifier and has a lower power rating. 


Another major difference is in the noise production. Warm mist humidifiers are quieter than cool mist humidifiers. 

The cool mist humidifier uses a fan to cool and circulate water, and the fan tends to give off some noise. However, the warm mist humidifier operates with a heating element, and it hardly gives off any noise. 

How to Deep Clean Your Warm Mist Humidifier 

After getting the perfect warm mist humidifier, you must take proper care of the device. Cleaning your humidifier is one of the ways you can take care of it, and it’s important to do this regularly to ensure that the humidifier works properly.

Clean the Removable Parts 

To clean your humidifier, the first step is to clean all the components that can be detached, such as the tank. Let’s look at these steps in detail.

Unplug the Humidifier 

Before attempting to do anything with the device, take some safety measures. Turn off the humidifier and leave it for some minutes. You should start the cleaning process only after the humidifier has cooled completely. 

Remove the Detachable Parts 

After the device has cooled completely, you can take it apart. Separate the detachable parts. You can look at the instruction manual to learn which parts are removable. 

Make a Vinegar Bath and Soak

We recommend using vinegar because it is an effective cleaning agent and also won’t negatively affect the humidifier. Prepare a large bath or sink and fill it with vinegar. 

Once you’ve prepared your bath, drop the removable parts of the humidifier in the vinegar and allow them to soak for 30 minutes.

Wash and Rinse 

Once you’ve soaked the parts for 30 minutes, the dirt, residue, and mildew should have become loose and easy to wash. Get a sponge and use it to scrub the parts completely until they are clean. 

After washing, remove the parts from the bath and rinse them extensively with distilled water. Dry them with a clean cloth and leave them to dry. 

Clean the Inside 

After you’ve washed the removable parts of the humidifier, the next step is cleaning the inside of the device. 

Get the Water Out 

You can’t wash your humidifier effectively if there is residual water inside. You need to remove any trace of water completely, and you can do this by shaking or upturning the humidifier. 

Fill With White Vinegar 

After you’ve completely removed the water content from the device, pour white vinegar into the reservoir. Leave the vinegar in the reservoir for about 30 minutes.

Get a Toothbrush 

Once you’ve soaked the insides of the humidifier in vinegar, use a toothbrush to clean the interior properly. We recommend a toothbrush because the brush can reach hard corners and you can apply a reasonable amount of force when cleaning.

Focus your scrubbing on the parts where mildew and residues are concentrated. 

Rinse and Reassemble 

After you’ve cleaned the insides with a toothbrush, empty the vinegar. Then, rinse the humidifier with clean water until there is no trace of vinegar. After rinsing, leave the humidifier to dry and then reassemble the parts correctly. 

Remember to follow your user’s manual if you’re having a hard time reassembling the humidifier. 

Tips When Using Your Warm Mist Humidifier 

Humidifier Moisturizing Air as Woman Reads

We’ve prepared some more tips that will help you make the best use of your humidifier. They include:

Empty the Tank Frequently 

It is advisable to change the water in your tank frequently. Most times, we want to wait for the water in the tank to run out before we refill it. However, leaving water in the tank for extended periods can encourage the growth of bacteria and mold. 

To ensure your health and safety, it is better if you change the water each time you want to use the humidifier. Also, don’t use just any type of water in the humidifier. Use distilled water or purified water. 

Keep Away From Fabric 

The warm mist humidifier produces warm and humid air, and these conditions are suitable for the growth of microbes. We advise that you avoid placing the humidifier on upholstery, fabric, or any other material that can support the growth of mold. 

Also, ensure that the humidifier is not spraying directly on fabric or upholstery to prevent the growth of mold. 

Use Caution Around Kids 

Warm mist humidifiers are more dangerous than cold mist humidifiers because of the heating element. We don’t advise leaving a warm mist humidifier where your kids can easily access it because it is a burn hazard. 

If you’re going to put a warm mist humidifier in your kid’s room, then place it in a location where they can’t reach it. 

Best Warm Mist Humidifier Brands

If you’re considering what brand of humidifier will be sufficient, you should consider the LEVOIT smart humidifiers and the Hupro brand. 


This brand produces some of the best humidifiers, and some of their products consist of both warm and cool mist humidifiers. 

We’ve looked at one of their products in our list earlier, and it’s easy to see why they are among the top smart humidifier choices. 


HuPro is another brand that has upped the humidifier game, and they have produced some of the best products out there. 

The HuPro Pro 771 is an example of a product that will make a great addition to your home.

Wrapping It Up

You can easily beat the cold weather by getting a warm mist humidifier for your living space. Warm mist humidifiers are great for maintaining a cozy atmosphere indoors and are also useful for fighting a cough and nasal congestion.
