Best Humidifier For Congestion

What exactly is congestion?

The technical term for nasal congestion is rhinitis. Medics use the term rhinitis to describe a condition marked by inflammation of the air passages’ inner linings. The inside of your nose has very delicate tissues. The tissues are perfectly designed to let the air move in and out with ease.

There are also tiny hairs called cilia. The cilia catch all the dirt and other unwanted particles that may be in the air you breathe. Therefore, the cilia protect your lungs from such impurities.

If the inner linings of your nose get irritated, you will have rhinitis. The irritation makes you feel that the inside of your nose passages is completely stuffed. This feeling makes it difficult for one to breathe well. You may also feel that your head is heavy because of the inability to breathe well.

In some cases, the swelling of the inner linings of your nasal cavity may be accompanied by mucus. As the mucus builds up inside the passage, you will feel the urge to blow your nose endlessly.

The irritation of the inner linings of your nasal cavity and accumulation of mucus causes a headache. The headache is because of pressure inside small spaces behind your nose called sinuses.

What Causes Congestion?

There are as many causes of nasal congestion as you can imagine. The following is a brief outline of a few things that can cause nasal congestion.

  • If the air in the room is full of contaminants, some people may easily experience nasal congestion. Pollutants may range from dust to even perfumes.
  • Common cold. Common cold is a major cause of nasal congestion. Nasal congestion occurs when one has a common cold because of the accumulation of mucus in the nasal cavity. Also, the need to keep blowing one’s nose contributes to the irritation of the nasal cavity’s inner linings. Thus, when you have a common cold, the chances are that you will also have nasal congestion.
  • Allergic reaction. Allergic reactions can also cause nasal congestion. If you are allergic to pollen and get into a room where the air has pollen, you will experience difficulties breathing because of nasal congestion.
  • Dry air. Very dry air may also cause nasal congestion. When the air indoors is very dry and cold during winter days and nights, one can easily experience nasal congestion. Dry air irritates the inside of your noses to cause inflammation.

What are the symptoms of congestion?

The symptoms of nasal congestion are clear that you can hardly mistake them for anything else. Although many people experience nasal congestion when they have a common cold, this is not always the case.

Besides, there are many other causes of nasal congestion apart from the common cold. Here are key symptoms that you can use to tell if one has nasal congestion.

swollen inner linings of the nasal passages

The soft tissue that is in the inner linings of your nose swells because of the irritation. The swelling is a natural response by the body to fight irritation.

However, the swelling makes you feel that your nasal cavities have suddenly narrowed. This feeling explains who one experiences difficulties in breathing when they have nasal congestion.


Head pains occur when one has congestion because of changes in air pressure inside the sinuses. The air pressure inside the sinuses must be maintained for you to feel well. When you have congestion, this balance gets disrupted. You will feel a sinus headache in the form of pain deep inside your head.

Stuffy and or running nose

When you have nasal congestion, you will experience a stuffy nose at one time and a running nose at the other. The stuffiness feels like mucus that is clogging the deep parts of your nasal cavity. You will also have a running nose when you have congestion.

However, blowing the nose does not help much because you will keep on feeling the urge to do it endlessly. The blowing does not clear the stuffy nose. It makes the headache worse because of the way you strain your tissues when blowing the nose.

Does humidifier help with congestion – Pros and cons of using a humidifier for congestion

A humidifier can help with nasal congestion. Here are some of how using a humidifier can be helpful if you have congestion.

  1. It helps you to sleep well. If you have a common cold or flu, sleeping will be a problem. The nasal congestion that arises from the common cold or flu will prevent you from sleeping well. A humidifier can make things easy for you. It will increase the amount of moisture in the air, which, in turn, will help you breathe better and sleep well.
  2. It helps to break the mucus. If you have accumulated mucus in the upper respiratory system and nasal congestion, using a humidifier is a good idea. As the level of humidity in the air increases, your clogged mucus will start to break. It will then be easy to clear the air passages.
  3. Soothing the passages. A humidifier can help during congestion by soothing your air passages. If you breathe in very dry air, the linings of the wall will get irritated. You can deal with this problem by breathing air that is humid enough. A humidifier can help you achieve this goal because it can maintain the recommended range’s humidity level.

Apart from the benefits of using a humidifier to clear nasal congestion, there are a few risks that you should watch out for.


If the air in your room becomes over humidified, you will feel very uncomfortable. Overhumidification can also exacerbate the symptoms of the common cold.

Luckily, modern humidifiers automatically adjust their misting performance according to the needs of the atmosphere. This mode of action prevents the humidifier from dissipating excess moisture than what is needed at any given time.

Is cool mist or warm mist better for congestion?

Both cool-mist and warm-mist humidifiers can help fight congestion. The choice of which specific type of humidifier that you need to use depends on the weather conditions.

It is cold and dry; then it would be wise to use a warm-mist humidifier. The warm mist from the humidifier will make you feel comfortable.

Go for a cool-mist humidifier when the weather is hot and dry. A cool-mist humidifier will create a slight chill in the room. This will help you feel better when it is very hot and dry outside and you have nasal congestion.

What is better for congestion – a humidifier or vaporizer?

Both a humidifier and a vaporizer can help you overcome congestion. Although these two devices look different, they help you achieve a common objective, which is to increase the amount of moisture in the air.

A vaporizer directly adds steam to the atmosphere in your house. A humidify first turns the water into a fine mist before diffusing it in the air.

If you have nasal congestion triggered by dry air in the house, you can use either a humidifier or a vaporizer. Both devices will help you feel better because they improve the quality of air in your indoor environment.

If you have a common cold and your nasal spaces are clogged, you can also use either a humidifier or a vaporizer. Any of these devices will help you feel better and overcome nasal congestion.

Humidifier or Dehumidifier for Congestion

Both a humidifier and dehumidifier can help you if you have congestion. However, it depends on several factors, including the cause of the congestion, allergic reactions, and the season.

A humidifier increases the amount of moisture in the air. You may want to use one of the air in your room is dry. A dehumidifier improves the quality of air in the house by removing excess moisture. Excessively humid air is as bad as dry air.

If the congestion is caused by an allergic reaction related to dry and cold air, you can use a humidifier to help ease the congestion. The humidifier will increase the amount of moisture in the air in the house.

As a result of the increase in moisture, you will be able to breathe better than when you are exposed to dry air. In the end, the congestion in your nasal cavity will ease.

If the congestion results from one being allergic to excessively humid air, a dehumidifier will be the right device to use. The dehumidifier will reduce the amount of moisture in the air. Once the air in the house becomes less humid, the allergic reaction will stop. In the end, the congestion in the nasal spaces will clear.

Other Remedies for Congestion

There are many other remedies for congestion apart from using either a humidifier or a dehumidifier. Most of these remedies help you to cope with the effects of congestion better before you eventually overcome it. Some help you by reducing the irritation in the inner walls of your nose, which causes congestion.

  • Taking a decongestant. Over the counter, decongestants are quite effective in helping you overcome nasal congestion. They work by reducing the flow of blood to the inner linings of your nasal cavity. With reduced blood flow, the irritation and swelling eventually die off.
  • Using a nasal spray. Nasal sprays work by directly helping to relieve the irritation in the inside of your nasal cavity. Just as decongestants, nasal sprays are readily available.
  • Sleeping with your head raised. If you use pillows to raise your head’s position, there will be less accumulation of mucus in your upper respiratory system. Doing this will help you sleep well and eventually overcome the nasal congestion.
  • Taking antihistamines. Antihistamines help to relieve the symptoms of nasal congestion if an allergic reaction causes the congestion. Antihistamines help your body stop overreacting to small pollutants or anything else you may be allergic to. Therefore, taking them is a good way of fighting nasal congestion.

Things to consider when choosing a humidifier for congestion

Choosing the right humidifier for congestion can be difficult if you are not particular about what you are looking for. Humidifiers vary in terms of their missing capacity, general design, runtimes, and control features. Here are a few things that you should look out for when buying a humidifier for congestion.


The capacity of a humidifier refers to its ability to diffuse mist. A high-capacity humidifier can dissipate large amounts of mist within short periods. Such humidifiers are ideal for large rooms. Low-capacity humidifiers disperse small amounts of mist within a short time. Such humidifiers are suitable for small rooms. Any humidifier that can dissipate an average of 500 ml in an hour is perfect.


Humidifiers, like any other electrical device, pose a small level of danger. The most common type of accident related to the humidifier is overheating. The devices can easily get damaged if they overheat. Luckily, modern brands of humidifiers have several inbuilt safety features to prevent this type of accident.

Go for humidifiers with advanced inbuilt safety features, including auto shut off and low water level warning. The auto shut off feature prevents overheating because it triggers the humidifier to automatically go off when the water tank is empty or removed.

The low water level warning feature comprises a sensor and a small red light. When the water level in the reservoir goes down, the sensor triggers the red light to switch on. When this happens, you can always replenish the water tank when the red-light indicator goes on.


It is easier to operate a humidifier that has few controls than one which has several. The best humidifiers in terms of ease of control have one knob that you can use to adjust their misting performance. The knob should be placed at a visible place, and that one can reach effortlessly.

Some humidifiers have advanced control features, including a remote control and a LED display. It is very convenient to use a remote control to adjust the misting performance of your humidifier. The touch functionality is also entirely accurate and convenient to use.


If you are going for a room humidifier, it is good to choose one that you can carry effortlessly. Room humidifiers need to be moved from one place to another. Whole-house humidifiers can effectively humidify the air in all the rooms of a small house. Choose humidifiers that are lightweight and with a compact design. It will be easy to move such humidifiers around the house.

The size of the water tank

Humidifiers that have large water tanks are better than those with small water reservoirs. Refilling the humidifier water tank takes some minutes. It would be cumbersome to keep on refilling the water tank when using your humidifier. To avoid this problem, go for humidifiers with large water tanks that can hold six or more liters at ago.

Additional features

Modern humidifiers come with a range of additional features. The most common other features in humidifiers are the essential oil tray and night mode. Companies that add these features on their humidifiers market the devices as 3-in-1. It is because you can use the device as a humidifier, diffuser, and source of special light at night.

The essential oil tray allows you to use the humidifier for scenting or aromatherapy. The essential oils get dissipated with the mist into the air in the room. The night mode feature entails bulbs that release a soothing light at night. For some humidifiers, one can adjust the light’s color and effects to suit their mood at night.

Choose humidifiers that have such additional features for your ultimate comfort. The night mode is critical if you intend to use the humidifier in bedrooms. It helps to soothe you and make you sleep quickly and soundly.

If you intend to use it in the kids’ bedroom, choose the humidifier with enhanced night lights. Some humidifiers can create the impression of a starry-filled night in the room. This and many other features may be particularly exciting to the kids at night.

You should avoid using hard water in your humidifier. Hard water has minerals that ultimately find their way to the atmosphere in your house if you put the water in a humidifier.

Also, the water tank design makes things easy when you need to clean every component of your humidifier. You can reach every part of the humidifier with your soft-bristled brush once you open the top.

Although this humidifier can be of great use whenever you need warm or cool mist in the house, it may increase your power bills. The heating element that boils the water before it is turned into warm mist consumes a lot of electric power.
