Warm Mist Humidifier Buying Guide
Warm mist humidifiers are quite common among allergy sufferers or people looking to add warm, humid air into their rooms. But is it the best option for you? This buying guide should help you make an informed decision.
What is a Warm Mist Humidifier?
A warm mist humidifier is a device that adds warm moist air into a room. While keeping the recommended humidity levels in a room, it also warms it up.
This is an added advantage because the warm air you breathe inside your home isn’t only safe, but also warm enough to keep you comfortable during the cold winter season. However, humidifiers shouldn’t be used as the primary heating source. So, it’s ideal if you invest in an electric space heater.
How does a Warm Mist Humidifier Work?
The purpose of any humidifier is to increase humidity in a room, home, or building. Humidity is essentially water in the air.
When the air inside your home is dry (low humidity), you are exposed to all kinds of health risk, including but not limited to respiratory ailments such as asthma, bronchitis, sinusitis, and nosebleeds and general dehydration.
Dry air can also cause skin irritation and eye itching and is associated with increased allergies, sore throat, and aggravated sickness symptoms. Humidifiers introduce sufficient humidity into the air around the home to prevent these health problems.
Warm mist humidifiers introduce mist (moist air) into our rooms by creating steam in an enclosed system and then releasing the steam into our rooms.
A basic warm mist humidifier would also be considered a vaporizer. It boils water, which at over 100 degrees turns into vapor. The vapor is then pushed out of the boiling tank into our rooms.
This mechanism often results in two main benefits; humidification and home heating. Since the vapor from warm mist humidifiers is hot, once released into the room, it spreads that heat throughout the room, warming the people within the area in the process.
There are a few things you need to know about the operation of warm mist humidifiers though. These include;
- Most don’t have filters: Evaporative humidifiers contain special filters that play a central role in the creation of mist. Most warm mist humidifiers, on the other hand, don’t have filters. Instead, they use boilers.
- You can opt for dual mist options: Instead of buying a pure warm mist humidifier, you can purchase a dual mist model. Mostly available in the ultrasonic form, dual mist humidifiers come with two separate settings; cool mist and warm mist. To get warm mist humidification, all you have to do is switch ON the warm mist settings.
Types of Warm Mist Humidifiers
There are two main categories of warm mist humidifiers;
-
Steam Vaporizer Humidifiers
Steam vaporizer humidifiers heat or boil water at very high temperatures to produce steam. The steam is then released into the surrounding air to increase humidity levels. If need be, medicinal inhalants can be introduced into the steam vapor to help lessen coughs and viral infections such as a common cold.
The main advantage of this type of humidifiers is that the heating process kills all germs, bacteria, and harmful viruses that would otherwise be introduced into indoor air. The result is clean, warm, and healthy moisture released into the room at a steady rate to hydrate your air while simultaneously warming the room.
One serious drawback, however, is heating hazards. During the heating process, parts of the vaporizer can become very hot. This makes vaporizers a significant safety risk for pets and young children and a potential threat even for adults.
A low-quality vaporizer would be even more unsafe as the heat source is likely to be poorly designed. This can result in overheating during use, putting room occupants at risk of burns and the home at risk of a fire. In a nutshell;
Advantages
- Fewer health concerns since germs are killed during heating
- Provides warmth and humidity to the environment
- No filters to worry about
Drawbacks
- Regular cleaning required to remove mineral deposits
- The heating surface gets hot, increasing the risk of burns
- Consumes a lot of energy
- Risk of fire hazard is higher
-
Ultrasonic Warm Mist Humidifiers
The main difference between steam vaporizer humidifiers and ultrasonic warm mist humidifiers is that the latter use a diaphragm to blow the warm air into your room. The diaphragm vibrates at high speed to break down water into mist.
Advantages
- Much quieter than steam/vaporizer models
- The humidifier uses less energy compared to steam/vaporizer models
- Easier to maintain
Drawbacks
- More expensive compared to steam/vaporizer models
- Cannot humidify large spaces
- Requires regular cleaning to prevent the build-up of mold
Pros and Cons of Warm Mist Humidifiers
Warm mist humidifiers are very effective at their job. But, they also come with a few drawbacks. The following are their top advantages and disadvantages.
Advantages
- Kill mold and bacteria: Warm mist humidifiers kill mold and bacteria in the tank before dispersing the vapor into the atmosphere. The heating element also sterilizes the water when boiling. As such, the vapor from these humidifiers is healthy and safe.
- They are silent: Vaporizer/steam models don’t have a fan, or if they do, it’s usually a small, quiet fan. This significantly reduces noise output. Ultrasonic models, meanwhile, don’t have a fan at all. The only sound they produce is ultrasonic vibration.
- Health benefits: Just like cool mist models, warm mist humidifiers carry significant health benefits. These include reducing nosebleeds, sore throat, and chapped lips. Warm mist humidifiers also reduce the amount of flu and cold viruses in the air and are suitable for dry skin.
- Eliminate allergens: For people with allergies, warm mist humidifiers remove allergens from the air better than cool mist models.
- House warming benefits: Above all, warm mist humidifiers are famous for their home-heating qualities.
Drawbacks
- Risk of burning: Since warm mist humidifiers involve heating to very high temperatures, the risk of burning an ever-present danger.
- House fires: Like other appliances that use electric heating elements, warm mist humidifiers can also cause house fires.
- Bacterial and mold build-up: Where the device isn’t properly maintained, mold and bacterial build-up are likely. This can result in coughs and colds.
- White ash: Warm mist humidifiers produce white ash as residue. This white ash can settle on items in the house, causing an unpleasant scene.
Warm Mist Versus Cool Mist Humidifiers: Which One is Better for Coughs, Babies, and Sinuses?
Both warm mist and cool mist humidifiers are equally effective at adding moisture to the air. However, there is a lot to ponder about when you decide to use a humidifier to ease coughing, sinus problems, and in babies rooms.
In this section, we will discuss and help you choose one that is ideal for your situation.
– Warm vs. Cool Mist Humidifiers for Coughs
Both warm mist and cool mist humidifiers can prove helpful for coughs and sore throat problems.
In warm mist humidifiers, since the water is boiled to 100 degrees, there is reduced risk of allergens and bacteria spreading in the room. The warm mist has also been shown to be soothing for coughing people – it makes breathing easier. Moreover, medications can be introduced into the mist for further health benefits.
Cool mist humidifiers are just as effective. Physicians have found that the cool mist alleviates inflammation in the airway, making it easier to breathe for people with coughs. The cool mist is also suitable for cough-related problems such as nasal congestion, inflamed nasal membranes, and sore throat.
– Warm Mist vs. Cool Mist Humidifiers for Babies
Both warm mist and cool mist humidifiers are effective at humidifying a baby’s room. By the time the moisture reaches your baby’s lower airways, it’s the same temperature regardless of whether the original moisture was warm or cold.
Since warm mist humidifiers become hot when in operation, though, they aren’t ideal for the baby’s room. Instead, opt for ultrasonic cool mist humidifiers. Also, cool mist humidifiers are better at easing coughs and congestion in children with cold.
One crucial thing you need to remember, however, is maintenance. Cleaning your humidifier prevents mineral buildup and the growth of bacteria and molds. Emptying the tank and drying all surfaces of the appliance daily is recommended.
– Warm Mist vs. Cool Mist Humidifiers for Sinuses
During the winter months, the air becomes dry both indoors and outdoors. Inhaling this dry air can be bad for your sinuses. Dry air can cause thicker mucus, blocked sinus passage, cracked nostrils, and general irritation. These conditions can lead to sinus infection.
The mist released from humidifiers can help alleviate this problem as it helps moisten the air and thins out the mucus inside your nose and sinuses.
Unsurprisingly, both warm mist and cool mist humidifiers are quite effective at this. Both provide the moisture necessary to humidify the air. What’s important is maintenance. A dirty, ill-maintained humidifier is even worse than having no humidifier.
Factors to Consider When Buying a Warm Mist Humidifier
Now that we’ve covered the basics, let’s look at a few factors you need to consider when buying a warm mist humidifier;
-
Size
Warm mist humidifiers come in various sizes depending on your needs. The most popular options are portable and tabletop models. The reason portable options are popular is that they are ideal for single-room humidification and generally safer.
Other than portable and tabletop models, you can also choose a large room or whole house furnace humidifiers. These units can add moisture to a single large room, medium-sized house, or apartment.
The largest options in this category are in-duct humidifiers. These usually serve as your central humidification system, distributing warm mist evenly throughout all the rooms in a house.
Other than in-duct systems, you can also opt for whole-house steam humidifiers which are larger than tabletop models. Console humidifiers may not serve an entire apartment, but they can efficiently distribute mist throughout a 1,700 square feet area. These larger humidifiers can be connected to the central water system, so you don’t have to worry about refilling the tank.
-
How Much Humidity do you Want?
Although humidity is good, only the right level is healthy. Too much moisture in the house can cause dampness. Combine this with the warmth produced by warm mist humidifiers, and you have the perfect conditions for mold and bacterial growth. Moisture can also affect wooden surfaces. When wooden furniture is exposed to a damp environment for extended periods, warping and rotting are possible.
For these reasons, you should buy a humidifier that generates the right amount of humidity. The recommended indoor humidity level is between30% to 50%. So, it’s important to maintain humidity levels at that. If you can find a humidifier that allows you to confirm and maintain such humidity levels, that would be brilliant. If not, purchase a hygrometer separately to help you keep track of the humidity in the home.
-
How Much Dust does it Produce?
One of the drawbacks of warm mist humidifiers is that they produce a by-product in the form of white dust. This white dust, though harmless, will be left floating around the home and often settles on furniture and other objects. The more minerals (salt) in your water, the more the white dust you’ll see.
Different models produce different amounts of white dust. So choose one that produces little dust.
-
How Much does it Cost?
There are two types of cost to keep in mind; the upfront cost of purchasing the appliance and running costs (for energy and maintenance).
With regards to purchasing costs, most warm mist humidifiers are priced in the $20 to $500 range. Typically, you’ll pay more for extra features since models with the most features offer more convenience and good user-experience.
You’ll also pay more for larger size humidifiers. Whole-home humidifiers, for example, are very expensive.
When it comes to the cost of running the appliance, most warm mist humidifiers use an electric heating element to heat the water. As such, they consume significant electrical power. It’s essential to check the power rating of the appliance to know how much energy it requires for a given period, say, every year.
How to Clean a Warm Mist Humidifier
Since warm mist humidifiers accumulate a lot of residues and attract mold and bacterial build-up, regular cleaning is necessary. We recommend maintaining a daily and weekly cleaning schedule;
-
Daily Cleaning
If you intend to use the humidifier daily, ensure to clean you clean it after every use. Turn it OFF and allow a few minutes for it to cool down. Then, drain and rinse the water tank. Also, wipe the medicine chamber, water tank, water tray, heater, and other parts with a soft, damp cloth. The chamber should be dry before the next use.
-
Weekly Cleaning
In addition to daily cleaning, once-in-a-week thorough cleaning is also necessary, which is why you should always choose an easy to clean humidifier. Begin by turning OFF the appliance and allowing it to cool. Then, proceed as follows;
- Take out the water tray and soak it in equal parts vinegar and water. Wait for 20 minutes, then rinse it and wipe with a clean cloth.
- Pour white vinegar into the heating chamber, wait for 20 minutes, and then thoroughly wipe the chamber with a soft cloth damped with vinegar.
- Rinse the chamber (without submerging). Then, wipe it again and allow it to dry. Don’t use a solution other than vinegar for this process.
Precautionary Measures when Using a Warm Mist Humidifier
Warm mist humidifiers can get hot during operation, so you need to take the necessary precautions to prevent the risk of fires and burns. Here are some things to keep in mind;
-
Get the Positioning Right
Where you place the humidifier has a massive impact on the safety of the occupants of the room. If there are children at home, position the unit out of their reach. The same applies if you have pets. Position the humidifier where the pets can’t get too close. If you’re thinking of using the humidifiers in your kid’s room, the answer is NO. Never leave a warm mist humidifier ON in your children’s room. Since the appliance expels moisture, place it in a safe spot, on a level, dry surface. Also, the humidifier shouldn’t be tilting.
-
Be careful with Cords
Electric cords are a huge problem in many homes and one of the top cause of home fires. To avoid any accidents, ensure that any cords used are tucked away safely. This applies to any wires and extensions connected to the appliance. Make sure that they aren’t in the way. Otherwise, one of the kids or pets can get entangled in the cables, creating an unnecessary safety risk.
-
Be Careful with Electricity
The risk of electrocution remains the same as with other electronic appliances. You could even say that the risk is higher for humidifiers because they use water, which is an excellent conductor of electricity. To this end, whenever you’re refilling the tank, make sure that all electric supplies to the appliance are switched off and plugged out.
-
Always Use Distilled Water
Never use tap water to refill the humidifier. Tap water is hard and comes with a lot of residues. You’ll have a lot of sediment in the unit after each use, which means you have to clean more often. Soft water can be used, but not in all humidifiers. If you’d like to use softened water, check your model to confirm that soft water is allowed. If not, stick to distilled water.
Conclusion
Many features can be the determining factor when deciding which warm mist humidifier to buy. You might love a larger tank capacity, or have a weakness for special features that make the unit more convenient. As a consumer, it’s completely up to you to decide the type of humidifier that suits your needs best. Now that you’re informed about some of the best warm mist humidifier for large rooms, the decision-making process will be a lot easier.
