The Basics of Warm Mist Humidifiers

  • How does a warm mist humidifier work?

best warm mist humidifiersBy now, you probably know the aim of a humidifier – to increase the humidity in a room, home or building, and make you feel comfortable and put an end to coughing. Dry air can have several impacts on your health. For example, it can give you cracked skin, a sore throat, or it can increase your allergies and aggravate your sickness symptoms.

For that reason, purchasing a humidifier could be ideal, especially during winter. As the weather gets colder, you would want to stay inside the house more. So, you will need something that will reduce the cold weather effects. It doesn’t only help with cold weather symptoms, though. It’s also a great ally for people with asthma, and for people with allergies.

A warm mist humidifier is a great investment. Most of these products are vaporizers, meaning that they boil water and create moisture by releasing steam. This way, they maintain your home’s humidity at a proper level and they increase the warmth of the room.

Also, most of them work with no noise. A warm mist humidifier doesn’t require a fan in order to distribute moisture, meaning that you can sleep like a baby even when it’s turned on during the night.

The way it works is pretty simple. It boils the water in the tank until it vaporizes. Consequently, it moisturizes the air in your room, and it maintains the humidity as well as the warmth.

Moreover, it fights off the mold and bacteria that develops in the tank, so you don’t have to worry about them. This thing makes warm mist humidifiers very healthy and beneficial. They can be used as steam medications too, but you should consult a physician before that, so he/she can advise you on that. In addition, if you are struggling with allergy or asthma symptoms, you can use warm mist humidifiers, as they work for that too.

These types of humidifiers also work without you having to replace the filters. Another great thing is the fact that they can collect any minerals that are leftover from the heated water.

  • What is the difference between a cool and warm mist humidifier?

cool and warm mist humidifierWhen it comes to mist humidifiers, you have two options – warm and cold ones. Although both of them pretty much have the same goal – keeping a room’s humidity – they are different in the way they operate.

Now, the names are pretty descriptive – a cool mist humidifier sprays cold mist, whereas a warm mist humidifier sprays warm one. Still, which are the other differences you should know about, to decide on the best whole house humidifiers for you. Here’s a list.

  1. Working Style

Cold mist humidifiers come in two types: evaporative and ultrasonic.

The ultrasonic humidifier uses vibrated technology that helps it break water down into small droplets, which then turn into cool mist particles. They are less noisy compared to evaporative ones. Evaporative ones, on the other hand, increase humidity with the fan and wick filter. Basically, the water in the tank flows to the wick filter, which is blown by the fan and, as a result, turns into cool mist.

At the same time, warm mist humidifiers are different. They boil the water, and then vaporize it in the air, making your room feel warm.

  1. Noise

Because cool mist humidifiers use a fan to generate the mist, they tend to be noisier, meaning you may want to consider some earplugs if you let them on while sleeping.

On the other hand, warm mist humidifiers are very quiet. They don’t use a fan, as they boil the water in order to create warm mist and release it into the air. The only sound you will hear is from the boiling water, or the sound it does when the water is being dispensed and ready to heat.

  1. Price

Warm mist humidifiers require heating elements because they generate warm mist and can keep a room’s warmth. For that reason, they tend to be more expensive.

Cool mist humidifiers are less expensive due to the lack of heating elements.

  1. Electricity

Because of the heating elements, warm mist humidifiers require more electricity in order to function properly. At the same time, cool mist ones require less electricity, because they own no heating elements, so they are more merciful with your electricity bill.

  1. Mold and Bacteria

As already mentioned earlier in the article, warm mist humidifiers have the advantage of killing bacteria and getting rid of mold due to boiling the water. They can be a very healthy investment, as they don’t make you inhale bacteria. They still need to be cleaned regularly, as the hard water residue can become a problem.

However, cold mist ones are more at risk of growing bacteria and mold. Because of that, they are a less healthy choice. Moreover, you have to clean them regularly as well, in order to keep mold and bacteria away.

  1. Replacements

Whereas warm mist humidifiers don’t need filter replacement, evaporative ones do, because they require a fan. Therefore, you will have to replace it from time to time.

  1. Risks

Although it’s not always likely to happen, warm mist humidifiers are more dangerous compared to cold ones. If you have a child that is always running around the house, the humidifier can become a danger, especially if not placed safely.

If it is tipped over because of a mistake, the hot water can cause serious burns and injuries, which can be very dangerous, especially for children and pets. Because of that, you need to pay extra attention and think about a safe place where you could keep it.

Meanwhile, a cold mist humidifier is safer from that point of view. It doesn’t boil the water, meaning there’s no danger in case it’s tipped over.

Therefore, warm and cool mist humidifiers are pretty different from each other, even though they both aim to keep your house humid enough. They work differently, have certain risks and their prices differ, as well. So, choosing the most popular cold mist humidifiers or warm humidifiers is up to you.

  • If you don’t clean the humidifier properly, bacteria can grow and cause coughs and colds. Although warm mist humidifiers are known to kill bacteria in the tank, that doesn’t mean they don’t require cleaning. In order to keep fungal growth away from your device, it needs daily and weekly cleaning.
  • If you allow the unit to expel too much moisture, it can lead to mold on your walls. It does this through condensation, so you should be careful at how you use the device.

Warm Mist Humidifiers for Babies

Warm Mist Humidifiers for BabiesIf you have a baby, choosing the right humidifier is essential. The reason is the fact that babies should be safe and happy, and a good humidifier can ensure that.

If the baby room needs to get moisturized, then placing a humidifier in the room can be a good idea. Warm mist humidifiers have the advantage of being very quiet, so if the baby sleeps, the device won’t wake him/her up.

Additionally, they are healthy and don’t vaporize any bacteria in the air, as they kill them in the tank, meaning the air your baby breathes will be bacteria-free.

However, as mentioned, this doesn’t come without risks. Should the device fall, the baby can get injured, and considering how sensitive babies are, they could get serious burns. You want to keep your baby safe, so placing the humidifier accordingly should be taken into consideration. Make sure you put it somewhere away from the baby, where it’s won’t do any damage if it falls.

How to Clean Your Warm Mist Humidifier?

Because it tends to accumulate mold and bacteria over time, it’s essential to keep your humidifier clean. Moreover, a clean device is a healthy one. It may kill bacteria in the tank before releasing the mist, but that doesn’t mean cleaning it is not essential. Therefore, here is how you can maintain your device:

  • Every Day

If you use the warm mist humidifier every day, it’s important to clean it daily, so it doesn’t accumulate bacteria. Due to the warm and moist environment, this could happen, and it could become very unhealthy.

In order to clean it daily, you need to turn it off and let it cool down before you start the cleaning process because it’s too hot and you may burn your skin. After each use, drain and rinse the water tank.

Each day, after this is performed, you should wipe the medicine chamber, water tank, heater, water tray, and other parts. Use a soft and clean cloth for this.

Make sure that there is no water left in the chambers after you use and clean it.

  • Every Week

Weekly cleaning is also important in maintaining the device. This process is more complex and it takes longer than the daily procedure.

So, you should turn your humidifier off and wait for it to cool down. After that, you can disassemble it. Take the water tray and soak it in equal parts vinegar and water. Do this for about 20 minutes. After this time passes, take a soft, clean cloth to rinse and dry it.

The next step is pouring white vinegar into the heating chamber. Again, this is a process that should take about 20 minutes, so let it sit there for that long. Afterward, take a clean cloth damped with vinegar and use it to remove any limescale deposits from the heating chamber.

Rinse the heating chamber but don’t submerge. However, make sure you don’t use any solutions other than vinegar to clean these parts. So, stay away from soaps or other similar products. You may place the cooling chamber, water tray and medicine cup in the top rack of a dishwasher, though.
