Buying Guide

A humidifier can be a great way to relieve the symptoms of a cough or cold, but with so many models on the market, it can be tricky to find the best one. So, here we’ve compiled a buying guide with the features to consider and answers to some common questions to help you.

How does a humidifier help coughs?

6 Best Humidifiers for Coughs, Sore Sinuses and Itchy Throats

When people have a cough, it tends to dry out their throats and nasal passageways. This is more likely if the humidity in your home is too low and many people purchase a humidifier to correct this issue. When the humidity is raised the symptoms of coughs, colds and sore throats are eased significantly. The throat is moistened and any inflammation in the nasal passage is reduced. When the air is more humid sinus congestion is alleviated and most people find that this leads to a more restful night of sleep. If you have a larger bedroom the Levoit LV600HH Humidifier for Large Room is the best humidifier for coughing at night according to many users.

Features to consider when choosing a humidifier for coughs

With so many humidifier options on the market, it can be a challenge to buy the right one. So, here we’ll look at the features to consider before you make your final purchase decision.

Type

Most modern humidifiers can produce both warm and cold mist throughout the day and night. As you might expect, a colder mist is very soothing during the hotter summer months and a warmer mist is a refreshing option when the weather is cold outside.
Most people use their humidifier during the coldest times of the year to combat the effects of the cold and flu season. So, it’s a great idea to ensure that the humidifier that you purchase has the warm mist functionality that you need. If you need a humidifier for a larger room or office or even an entire apartment, the treated air particles will be at room temperature before they reach you. So, it makes sense to get a humidifier that has enough coverage to meet your individual needs or double up and get an extra humidifier for a different area of your home or office. A humidifier with warm mist capability will contain a heating element and it’s a good idea to keep kids and pets away from the unit when it’s operating.

Water tank capacity

The water tank capacity of your chosen humidifier is important for a couple of key reasons. Firstly, the water tank size will determine how much warm or cold mist the unit can distribute into the atmosphere of your indoor space. A humidifier with a larger water capacity can be used to moisten larger areas for longer periods of time. Secondly, a large water tank capacity means that you won’t need to refill the tank as frequently as a smaller water tank. A humidifier with a larger water tank will be more effective and efficient compared to a smaller unit. That being said, a humidifier with a larger water tank tends to be larger, bulkier and heavier than smaller humidifier units.

Runtime

6 Best Humidifiers for Coughs, Sore Sinuses and Itchy Throats

The runtime or mist time refers to the time period that the humidifier can mist before the water tank runs dry. Most modern humidifiers such as the Elechomes UC5501 Ultrasonic Humidifier have multiple settings to select. So, if you notice that the advertising states that a particular humidifier has a runtime of up to 20 hours this is probably true on the lowest setting only. That same unit used on a higher setting may have a shorter runtime of up to 10-12 hours or less. So, if you’re planning to use your humidifier at night you’re going to need a model with a runtime of at least 8-10 hours to cover your sleeping and waking routine.

Coverage area

We briefly touched upon this earlier, every humidifier model will cover a maximum area and it’s important to bear this in mind before you make a purchase. A smaller humidifier could sit on a desk or table and it may have enough coverage to humidify a small room only. The largest humidifiers such as a furnace humidifier would be large enough to cover an entire home. Most domestic humidifiers fall somewhere in between these two extremes but it’s a great idea to match the humidifier coverage to the size of your home. This will ensure that your new humidifier is effective and efficient for that space.

Generally, small rooms are up to 250 square feet, while medium rooms are up to 400 square feet and anything up to 600 square feet is classed as a large room.

Noise level

Even the quietest humidifiers such as the Hupro Premium Ultrasonic Humidifier generate some noise when operating. If you need a humidifier in your bedroom it’s important to consider the operating noise. We all need a calm and quiet bedroom to get a full and relaxing night of rest. Generally speaking, the larger a humidifier is, the noisier it will be and this is another good reason to carefully size your humidifier. It’s also worth noting that evaporative and warm mist models tend to be louder as well. This is due to the heating elements and extra components needed to distribute the heated mist. If you’re very sensitive to sounds at night the Vicks Warm Mist Humidifier V750 is a great model to choose.

Essential oil compatibility

Many people enjoy using essential oils, they add an intoxicating aroma to your indoor spaces and they can help users to relax after a stressful day. If you’re new to essential oils or a regular user you want to purchase a humidifier model that has a diffusing option for your favorite essential oils. Some Humidifier models such as the Levoit LV600HH Humidifier for Large Room are very effective at diffusing essential oils and you can save time and money by only purchasing a single unit for humidifying and diffusing.

Ease of cleaning

6 Best Humidifiers for Coughs, Sore Sinuses and Itchy Throats

Every humidifier will require regular cleaning and the water tank will need to be refilled. A humidifier is designed to distribute clean mist to alleviate the effects of dry air on the nose and throat. If the unit is dirty this will make the humidifier less effective and it may even exacerbate the problem. So, when you purchase a new humidifier it makes sense to get a model that’s easy to clean and refill.

Other features

There are humidifiers such as the PurSteam 2.2L Ultrasonic Cool Mist Humidifier that are basic in terms of features and yet effective as a simple humidifying system. Generally speaking, the more basic modern humidifiers are less expensive than those with all the extra features. But, there may be some extra features that you don’t want to miss out on because they can be a game changer.

A prime example of a useful feature is the automatic shutoff function which is a great safety measure when you’re using the unit in a bedroom.  A humidifier with auto shutoff can be left running all night because it will automatically shut down if the unit is overheating.
The last thing that you want is a humidifier that overheats in your kids bedroom at night and this could have tragic consequences. We think that an auto shutoff feature should be regarded as a must have on your next humidifier model.

A timer function that can adjust the intensity levels at different times during the day and night is another great feature. This will help the user to get the exact level of cool or warm mist when they need it most without any need to constantly fiddle with the unit.

Some modern humidifiers have a filtration system that can be effective for those with severe respiratory complaints and allergies. But, for most users this is overkill and using filters can add a great deal of expense and hassle. Choosing a filterless humidifier will suffice for most homes and these types of models are usually easier to use and maintain.

Finally, you want a humidifier that has a longer warranty to ensure your peace of mind. A humidifier is a complex piece of electronic equipment and it can fail from time to time. So, it’s always a great idea to have a solid guarantee and a longer warranty shows that the manufacturer has confidence in that humidifier model.

FAQ

Providing you keep your humidifier clean and free of bacteria, using it should not make a cough or your cold symptoms worse.

It depends on the season. However, since you’re more likely to have a cough in winter, you’re more likely to find warm mist more soothing.

Experts agree that it is safe to run a humidifier all night. However, you need to be aware of how your body and home react to the humidity.

Our Verdict

As you can see, there are some fantastic humidifier models on the market. From the affordable Vicks Warm Mist Humidifier V750, which is easy to clean and use, while offering a medicinal inhalant functionality to the Levoit LV600HH Humidifier that has an excellent capacity for larger rooms and longer misting sessions, even with essential oils.

However, the stand out as the best humidifier for coughs has to be our editor’s pick, the Elechomes UC5501 Ultrasonic Humidifier. This fantastic model offers a large coverage area with quiet operation. Additionally, the compatibility with essential oils means that you can use this humidifier for relaxing aromatherapy sessions. Although it is one of the more costly options on this list, the UC5501 is certainly worth the investment.
