A persistent cough can ruin your day, not to mention a good night’s sleep. While over-the-counter medication or homemade cough remedies help, I remember inhaling vapor from a steam bowl relieved chesty cough during my younger days. Now, for convenience, people are turning to electrical devices for comfort. In this case, the humidifier, based on the same concept using vapor or moisture. You ought to know there are several types of humidifiers – warm mist and cool mist and further categorized into ultrasonic and evaporative. Before you get one, find out which type of humidifier is good for cough. But what if I tell you a humidifier can make a cough worse. I will explain as you read on.
Firstly, you have to know
Types of Humidifiers & Pros and Cons
Generally, there are 3 types of humidifiers
- Warm mist
- Cool mist
- – Evaporative
- – Ultrasonic
Let’s look into these 3 individually including their pros and cons.
1. Warm Mist Humidifier
It uses a heating element to boil water and make steam. As a result, the rooms’ air is slightly warm. The unit can be used with certain medicated products to improve cough relief.
The Good. A warm mist humidifier is better for reducing bacteria and germs, and its moisture saturation is higher. Since it operates without an internal fan, it is quieter than the cool mist machine. Also, the warm air may be nice to warm winter air.
The bad. It requires more energy and the heat can be dangerous if you have children around or pets. Furthermore, heat can possibly aggravate eczema symptoms in severe cases.
2. Cool Mist Evaporative Humidifier
This machine uses a fan to draw air through a wick filter and then releases the vapor in the air, giving a chilling effect in the room. Great for use during the hot and humid summertime.
The good. This is safer for children and pets as it does not have the heating element of a warm mist machine. Without it is more energy-efficient.
The bad. Cool mist humidifier can accumulate bacteria and mold growth more easily if not maintained properly. The wick filter needs cleaning and replacing. That is the task many people dislike. For a sound-sensitive person, the noise due to the fan can be disturbing.
3. Cool Mist Ultrasonic Humidifier
It uses a high-speed vibrating plate to turn water into a fine mist.
The good. Without fans and gurgling water, this may be the quietest humidifiers. Cleaning is hassle-free, just rinse the tank and internals.
The bad. An ultrasonic humidifier works without a filter thus minerals present in tap water are carried into the air along with the water droplets when it is in operation. These minerals may settle out of the air and leave fine white dust on surfaces near the humidifier. In this case, only use distilled water to run the machine.
A question you probably have in mind,
How Does Humidifier Help with Cough
Dry air can aggravate a dry cough. As a humidifier adds moisture to the air, it can provide relief.
When you have a chesty cough, you will want to cough up mucus or phlegm. However, young children may not be able to do so effectively. During the winter, the air is dry and coupled with the use of indoor heating, the dryness can make mucus more difficult to cough up or blow your nose. For these reasons, adding humidity to the air makes sense.
The next question I see. Is warm mist or cool mist humidifier better?
Warm mist and cool mist humidifiers are equally effective in humidifying the air in your home. Both are helpful in easing respiratory discomfort related to cough and colds. Nonetheless, by the time the vapors reaches your airways, the temperature is the same regardless it started out warm or cool.
8 Things to Consider When Buying Yours
Choosing your humidifier depends on how you plan on using it. Take into consideration children at home or pets. Are you using it in the bedroom or living hall?
Here are the factors to keep in mind when buying yours.
Where you live is important in deciding which machine you should choose.
Climate. If you live in a colder location, it is better that you look at warm mist humidifiers since the warm vapors help increase the temperature of the room to make you more comfortable. In this case, you may save a bit on your heating bills. On the contrary, living in a warmer location, you may consider getting a cool mist unit because it helps reduce the temperature of your room.
Water quality. Some humidifier brands will recommend to simply use tap water to fill the tank. Take note the ultrasonic cool mist humidifier is not suitable for hard water areas because it does not operate with a filter. A research, found doing so, resulted in more harmful particles emitted into your room. This will lead to more respiratory issues. If your choice of humidifier is an ultrasonic unit for certain reasons, always fill the tank with distilled water.
Where will you be placing the humidifier? An economical tabletop humidifier is sufficed for your bedroom but how big is the room. You need to know the capacity of the humidifier and its space coverage. A console humidifier is needed to be able to humidify your entire living hall. Most medium-priced humidifiers can handle rooms approximately 200-500 square feet, but the more expensive ones can easily double or triple that figure.
Whom is the humidifier intended for? A cool mist humidifier is best used with children and the elderly. You do not want them to accidentally knock over a warm mist humidifier and risk scalding. And how about those curious pets? If you think a warm mist humidifier works better for you, make sure it is placed at the safest location.
Warm mist and ultrasonic are the quietest types of humidifiers because they do not operate using a fan. It is the fan that creates the noise. On a low setting, it may be quieter but on high, it may disturb your sleep. You also need to know a warm mist humidifier may make some gurgling sounds as the water heats.
4. Water Tank Size
Most humidifiers have a 2-3 days capacity when operating on the lowest setting. Some will only last hours thus need constant refilling. If you intend to leave it running all night, would you be frustrated? I will. So, take note of the water tank capacity.
Also, will it be easy for you to remove and refill the tank? You want to fill and fit the water tank without spilling. Imagine a tank filled with water, it will be quite heavy depending on the size and you trying to reattach to the machine. It may not be done smoothly thus spills commonplace. I have experienced this with my cooler fan, more work. This leads to the next factor,
5. Ease of Cleaning
Maintaining your humidifier is important to avoid harmful bacteria from entering your home and, mold and mildew growth. You must look at the design and shape of the water tank because some odd shapes have hard to reach places to clean effectively. Though some humidifiers especially table-top are exquisitely designed, cleaning can be difficult if not impossible.
6. Good to Have Features
More features, more pricey and that’s a fact. Some machines come with features you may hardly use but some are actually good to have. Here are a few you should consider.
Auto shut-off is a very common feature in many electrical appliances or devices. For a humidifier, it will auto shut off when the water level is low. This comes in handy in case you actually forget to refill the tank where most units need to every 2-3 days.
A humidistat senses changes to the amount of moisture in the air. Based on the readings, the humidistat turns off the humidifier after the desired humidity level has been achieved. On the other hand, turns on when the air is dry. It is important to maintain a healthy moisture level in your home thus a humidistat is a useful feature to have. If a unit you have eyes on does not come with a humidistat, you may consider buying a hygrometer (cost around $10) to monitor your room’s humidity levels.
A timer lets you set your humidifier to on or off at a particular time. This is ideal if you wish to minimize electricity bills while still able to get clean moisturized air.
Water tank indicator signals you when to refill the tank. If you are a forgetful person, this may be good to have. Else, the auto shut off would suffice. Choose either one or have them both.
Filter indicator is a feature you must consider carefully. The filter is vital in cleaning the air. If it becomes clogged with pollutants, they will end up being dispersed back into the air in your home. For this reason, knowing when the filter needs cleaning or changing is important.
7. Aroma Diffuser
Some humidifiers come with a separate compartment, allowing you to add aromatherapy oils, essential oils or medicinal additives. This means they humidify and scent your room while attending to conditions such as cough and cold. Aromatherapy oils are known to reduce stress level and headaches, good for sleep and relaxation. Medicinal additives such as lemon oils, tea tree and menthol may help ease nasal congestion.
The price of a humidifier for home use can range anywhere from $30 to over $300. Surely, you want to get one that fit the purpose without breaking a bank. If you only want to humidify a specific area of your home, for example, a bedroom or work/reading corner, a tabletop unit is sufficient for the task. There is some nicely designed tabletop humidifier to blend in with the design or concept of your room and this will cost more. Designer series may look exquisite but ensure the unit is easy to clean without unreachable corners.
Now that you have a very good idea of how you are going to use the humidifier and the factors to look out for, let’s find out what your options are.

All in all
Choosing the right humidifier can be overwhelming considering all the choices and features available. Ultimately, the decision is yours and I hope all the factors brought up here plus the list of best humidifiers for home use gives you the confidence to choose wisely.
You should always keep in mind why you are buying a humidifier. Is it for cough relief and other nasal related problems? Are you prone to dry and itchy skin? Or simple need it for better sleep? Plants and pets also need good humidity level to stay healthy.
While it is good to have a powerful console humidifier, you need to understand too much humidity can cause health issues. High humidity levels can create dampness in the air and this encourages the growth of mold, mildew and harmful bacteria.
The use of a humidifier, if the humidity level is not checked and the machine not cleaned properly can make a cough worse and may increase the risk of catching a cold or flu.
Mayo Clinic recommends that humidity stays between 30% – 50%. A hygrometer can determine the humidity level in your room. If the humidifier does not come with this feature, you can easily get one at hardware stores or on Amazon. Make sure you are properly regulating the output of your humidifier. Test the humidity daily, particularly if someone at your home has allergies, asthma or respiratory problems.
Besides using a humidifier for cough relief, herbs and spices are good too. Find out how to make home remedies for cough using herbs and spices you probably already have in your kitchen. Read here.
