Of course, it is compact, weighing only 2.27 lbs., meaning that you can easily move it from one room to another. Also, it takes the minimum amount of space.

It is true that the 0.4-gallon water tank is quite small. Still, if you plan on using the humidifier only at nighttime, filling the tank once a day will suffice.

More specifically, one tank refill should last approximately 16 hours – if you select the most powerful mist output. Aside from that, thanks to the 360-degree mist nozzle, you can choose to direct the mist wherever you want – towards the areas that actually need moisture.

As for the optional blue nightlight, some former users have found it soothing, while others said it was too bright. Therefore, it is a matter of personal choice. And while the humidifier is easy to fill, due to the rather small opening, scrubbing inside the tank can be a challenge, even with the included cleaning brush.

The integrated night light is another feature worth mentioning. It isn’t too bright so that it is disturbing, but it can be really useful for youngsters, in particular.

On the other hand, kids might knock the humidifier over rather easily. This is why it might be useful to be able to lock the top compartment. On a different note, we’ve found that changing the pads inside the aromatherapy drawer is a bit time-consuming.

Nonetheless, do note that the manufacturer recommends using distilled water with the humidifier. That’s specifically because tap water consists of chlorine and other harmful components, among other things, which have harmful effects on your health.

At the same time, even if the humidifier features a silver-ion antibacterial agent, this doesn’t eliminate the need to clean it on a regular basis. This will also improve the lifespan of the unit while ensuring that you breathe fresh, clean air.

Similar to some of the products we reviewed beforehand, this also comes with the optional night light. So, it’s entirely up to you whether you decide to actually use it or not.

The 0.7 – liter water tank ensures that the humidifier will work for 10 hours straight. That translates into continuous operation, which is useful, especially if you want to let it run during your sleep.

A potential drawback could be that the refill hole is a tad too small. Plus, it is a bit difficult to say if the screw is closed accordingly, as there’s no click or anything of the kind.

Sparoma Cool Mist HumidifierA compact humidifier is a go-to solution for solving the common problem of excessively dry indoor air.

What Are the Health Benefits of Using a Cool Mist Humidifier?

Health Benefits of Using a Cool Mist HumidifierThe health benefits of cool mist humidifiers are multifold. Not only that such a unit will add comfort to your house, but it will also enhance your health. It’s no surprise that people might want to invest in a humidifier for eczema, for example, or a humidifier for allergies because they are quite efficient in these situations.

With that in mind, let’s analyze the main benefits associated with humidifiers, shall we?

  • Battle Congestion

When the breathable air is excessively dry, this will lead to drying the membranes and nasal passages. As a result, they will be prone to irritation and swelling.

In order to respond to this, the body will produce a larger amount of nasal mucus, in order to compensate for the dryness. Expressly, the purpose of the overproduction of nasal mucus is to facilitate moisture to the affected areas.

Consequently, this is likely to trigger unpleasant, uncomfortable congestion. In this view, humidifying the indoor air could make the world of a difference.

Evidently, this will provide a comfortable breathable air, meaning that the body will no longer have to overproduce moisture. Hence, if you’re regularly dealing with congestion, a humidifier might address this problem.

  • Boost Your Immunity

Did you know that your body’s defense against harmful bacteria and viruses is represented by the mucous membranes? However, in order for these to function accordingly, they have to stay moisturized.

When you breathe overly dry air, this will imminently attract the moisture out of the membranes. That will leave them incapable of protecting you. As a result, your immunity is compromised.

Nevertheless, if the air you breathe has a proper moisture level, then the membranes will regain their moisture. As a result, your immunity will greatly benefit from this.

Your overall health will get a boost from all three main devices that we have reviewed on our home page.

  • Soothe the Symptoms of Chronic Obstructive Pulmonary Disease (COPD)

Unfortunately, chronic obstructive pulmonary disease (COPD), is an overly common condition. If you are suffering from it, then you must know that any lung irritation can have devastating effects on your overall health.

In this respect, dry air has been proven to be specifically harmful to people with this condition. This is why an appropriate humidifier can soothe the symptoms of this disease, preventing it from causing you more discomfort.

Nonetheless, note that you shouldn’t over humidify the air either, as this could trigger other unwanted complications.

  • Address the Symptoms Associated with Croup

When it comes to croup, both cool and warm steam can lessen the symptoms linked to the condition. Nevertheless, to benefit from a humidifier, it would be best to get one and locate it in an enclosed space.

In general, the steam does an excellent job of breaking down anything in the throat, whereas the cold mist is known to diminish the swelling.

  • Facilitate Breathing Comfort to Asthma Sufferers

Did you ever wonder: is a humidifier good for asthma? If you have, then you should know that the answer is “yes”. In fact, a cool-mist humidifier is believed to be more efficient for asthma sufferers.

That’s because warm air is prone to irritate the lungs. You might know by now that any lung irritation could trigger asthma attacks. On a different note, if you’re suffering from asthma, or you’re prone to this condition, make sure you invest in a unit that allows you to adjust the humidity level accordingly.

This way, you can customize the moisture levels depending on how you feel most comfortable.

  • Diminish the Severity of Allergies

Are you dealing with allergies? We know how unpleasant allergies can be; especially since they are unpredictable, and they can break havoc on you without any additional notice. In fact, allergies are known to cause a common condition – namely allergic rhinitis.

This condition triggers nasal irritation, congestion, and inflammation. This is why it might be a sensible choice to invest in a humidifier, as such a unit does an excellent job of treating the symptoms of rhinitis.

  • Keep the Little One’s Comfortable

Many people consider investing in a humidifier when they first become parents. That’s because babies are overly sensitive, especially when it comes to sudden changes in the environment. At the same time, when the air is overly dry, babies are likely to develop various skin conditions.

Another concern could be that of congestion – which is why a humidifier will certainly come in handy. With that in mind, if the baby breathes comfortably, that means he/she is likely to sleep better, and uninterruptedly, which is a perk for sleep-deprived parents.

  • Relieve Severe Skin Conditions

Did you know that one of the main triggers of dry skin and eczema is dry air? Hence, by humidifying the air, you can prevent the worsening of the condition. Essentially, the moisture in the air diminishes the feeling of itchiness and unpleasant tightness.

Choosing the Right Humidifier for Your Needs: Portable vs. Single Room vs. Whole House Units

best humidifiers for bedroomSo, what should you choose from a portable humidifier, a whole-house humidifier, or a single room humidifier? To help you, we’d like to shortly outline the main characteristics of each device. Evidently, your needs should eventually dictate your decision.

Firstly, the main benefit of a whole-house unit is that, once it is installed and linked to your house’s system, it requires little to no maintenance at all. At the same time, it covers your entire house, meaning that you can control the moisture level inside your entire house. However, the upfront cost is considerable, not to mention that you have to factor in the professional installation, which is required in most cases.

In regards to portable units, these usually come on wheels, allowing you to move them around the house. Typically, such a unit is powerful enough to humidify two rooms or so. Some might be more powerful, depending on the specifications of the products. While they might be more powerful than whole-house units, they take up a lot of space, while being quite pricey, as well.

Meanwhile, a single room humidifier usually requires a lower upfront investment. Such a unit also allows you to control the humidity levels but in a much more restricted space. It is highly suitable for a bedroom, office, so on and so forth, having its limitations in terms of space coverage.

Choosing between Warm and Cool Mist Humidifiers: Which One Can Combat Coughing?

cool mist humidifier reviewsEven if we’ve focused primarily on cool mist humidifiers, we’d like to address a common question, namely what is more beneficial: a warm or cool mist unit? More specifically, which one is better for coughing or respiratory problems?

Expressly, we couldn’t say that one category is superior to the other, as each one comes with its specifications. Nevertheless, a type of unit might be better suited for you, depending on your needs.

For example, in the case of respiratory problems and coughing, you should know that warm air – namely warm and moist air, could trigger the aggravation of the condition. However, in general, by the time the vapor reaches the lower airways, the mist will be the same temperature as the air, no matter if it started out cool or warm.

On a different note, if you are concerned about bacteria and mold, then a warm mist humidifier is a better alternative. That’s because such a unit kills mold and bacteria while the water is boiled.

Should You Get a Humidifier that Has a Filter or One that Doesn’t?

As you know by now, there are numerous humidifiers on the market – some have filters, some don’t. The question that naturally follows is: which option is better? With that in mind, let’s assess the main characteristics of humidifiers with and without filters.

With a Filter

  • If you’re suffering from allergies, asthma, COPD, or other conditions, it might be more sensible to get a unit with a filter. At the same time, if you want to get a humidifier for a nursery or children’s room, the inclusion of a filter will ensure that the air is as clean as it can be.
  • Mineral dust, which is also referred to as white dust, is contained in the filter. Therefore, it won’t end up on your furniture, curtains, so on and so forth.
  • Generally speaking, filtered humidifiers are more conveniently priced than their counterparts.
  • These models are usually easier to operate since they have a straightforward, basic design.
  • Humidifiers equipped with filters also have fans, which produce a very specific noise. Some people could find that noise comforting. But it’s definitely a matter of personal preference.

Without a Filter

  • Humidifiers that don’t have a filter don’t require a fan. Therefore, they are much quieter than their counterparts. So, if you are a light sleeper, such a unit might be better suited for you.
  • They are easier to maintain, considering that they don’t require a lot of cleaning.
  • Since you don’t have to replace the filter on a regular basis, you could save money over the course of time.
  • Usually, if you choose a unit without a filter, this would require you to utilize distilled water.
  • Getting such a unit might require you to use another form of air purification, such as filters on your HVAC system. Another option could be investing in an air purifier.
  • Units without filters typically come with a range of advanced characteristics.

The Main Types of Cool Mist Humidifiers

Now we’d like to talk about the main types of humidifiers and how they work. Let’s see what you should know in this respect.

  1. Evaporative Humidifier

Many people are undecided between evaporative and ultrasonic humidifiers. When it comes to an evaporative unit, there is a wick inside the appliance, whose purpose is to pull the water from the tank and up to the top of the wick. Afterward, the air is dispersed by a fan, leading to evaporation.

For the most part, evaporative humidifiers are considered to be the most common type. Usually, these units come with a filter, requiring filter maintenance.

  1. Air Washer Humidifier

In reference to air washer humidifiers, such a device is a mixture of air humidifiers and air purifiers. Thus, it adds therapeutic moisture to the breathable air, while eliminating allergy-triggering elements from the air.

  1. Ultrasonic Humidifier

Moving on, an ultrasonic humidifier transfers the water through a transducer. Essentially, the transducer breaks the molecules apart, which leads to creating a very fine mist. The highlight of these units is that they operate more quietly, and, usually, they don’t have a filter.

  1. Steam Vapor Humidifier

And lastly, steam vapor humidifiers depend on electricity to create steam. This type of unit isn’t recommended for families with children. That’s because the hot water inside the humidifier can be spilled and cause complications.
