Why is a humidifier good for people suffering from sinusitis?

Dry air and low humidity levels are not good for your sinuses. In fact, dry air can cause the mucus in the sinuses to dry up, become congested and hard. This can lead to painful inflammations of the sinuses.

Many people have recurring sinus problems at night time when trying to sleep.

A humidifier can help keep the humidity levels in your home or bedroom at healthy levels and thus prevent this congestion, pain, and problems.

The humidifier can help people suffering from sinus problems by:

  • Ensuring deeper and uninterrupted sleep
  • Promoting easier breathing
  • Reduction of sinus inflammations and pain, allergies and asthma attacks
  • Reduction of the risk of nosebleeds
  • Relief of throat pain, coughing, and nasal congestion
  • Preventing dry and itchy skin

Plus, running a humidifier at home will also make your pets and indoor plants feel better and more comfortable, as well as protect your hardwood floors and other wooden furniture from drying up and cracking.

How to tell whether the air inside is too dry?

Obviously, the best way to determine the humidity of the air indoors is to measure it with a hygrometer. If it reads a result of under 30%, then the humidity is definitely too low and particularly unpleasant and unhealthy for people with sinus problems, asthma and allergies.

But, keep in mind that having a humidity level, which is too high, is not healthy either.

With humidity of over 50%, the growth of mold, mildew, fungus and dust mites is boosted.

The fact is, you don’t really need a hygrometer to determine that the air inside is too dry if you notice the following:

  • Your skin is dry and itchy
  • Your mouth and throat are dry
  • You have unexplained nosebleeds in the morning
  • There is a lot of static electricity in your home, on your hair, clothes, and furniture

Types of humidifiers for sinus problems

The humidifiers which can help relieve and prevent sinus inflammations and sinusitis vary in type and form.

Here are the main types of humidifiers by capacity:

Whole-house humidifiers

These are usually supplied to your furnace or supply line, and humidify the air as it passes through them while the heating system is working.

These are usually easy to maintain and ensure that the entire home is humidified adequately with minimal effort.

Single room humidifiers

These are smaller and more portable types of humidifiers that will humidify the air in a certain area or room in the home or office.

They are usually less expensive and easier to fit and move around the home.

A humidifier like this is useful if you want to ensure that the moisture of the air only of a specific room is adequately humidified.

Here are the main types of humidifiers by the technology used

Cool mist humidifiers

These are also known as evaporative wick humidifiers and work by sucking in the dry air, passing it through a wick filter, and releasing it back into the room in the form of invisible cool mist via a fan.

The advantage of this type of humidifiers is that they actually clean the air through the filtration system as it passes through the wick filter. This means cleaner air and fewer respiratory or sinus problems.

Cool mist humidifiers are more suitable for areas with a hot and dry climate. They can help cool the air and also moisturize it, which means you can save money for air conditioning.

Warm mist humidifiers

This type is perfect for the wintertime when it is cold outdoors and dry inside.

They work via a gentle boiling process which heats the water and releases it in the form of warm vapors in the air.

Thanks to the boiling process, a large percentage of the airborne bacteria, allergens, and other harmful microorganisms get destroyed and clean air is released back to the room.

Some of the warm mist humidifiers have special essential oil evaporative cups that you can use for aromatherapy or inhalations for sinus congestion, throat pain, and cold relief.

Ultrasonic humidifiers

These are the newest of all types of humidifiers. They use a special transducer which, through vibrations at ultrasonic speed, breaks down the water into a light, pure, and refreshing mist that is released in the air.

Ultrasonic humidifiers are very quiet, bacteria-free and are low maintenance.

They are perfect for people suffering from sinus infections and problems.


These are similar to the warm mist humidifiers and produce warm and soothing vapor through a boiling process. Thanks to the boiling, the impurities from the water are removed before it is released into the air.

They are the most affordable types, and while they don’t have removable water tanks, they are easy to maintain and clean.

Features to look for when shopping for a humidifier for sinus problems

As you can see from our reviews of the quality humidifiers for sinus problems, we have listed several features that are among the most important ones to keep in mind when shopping for a humidifier for sinus problems or for any other reason.


Each of these units has a specific runtime, which is the amount of time it can produce mist or vapor before needing to be refilled.

Of course, the whole home humidifier on our list does not have such a limit and will run continuously 24/7 if you want it to.

But the other humidifiers have limited water tank capacities, as well as different mist output settings, which determine the runtime they have per refill.

If you are looking for a humidifier that will run all night continuously while you sleep, or all day long, then opt for one which has a runtime of at least 12 to 15 hours.

Remember that the runtime depends on the intensity and settings you are planning to use the humidifier on. The higher the output – the shorter the runtime will be.

Water tank capacity

This is the measure of the amount of water that the tank of the humidifier can hold.

Naturally, the more compact units have smaller tanks.

Before considering how large a tank capacity you need, you should consider the pros and cons of having a larger or smaller tank.

Larger tanks will need to be refilled less regularly, but the longer the water stays stagnant inside, the higher the risk of mildew and mold growth.

Smaller tanks will last for fewer hours and will need more often refilling, but they are usually easier to clean. on the other hand, if they cannot provide you with the humidity time you want, opt for a larger one.

Filtering properties

Many humidifiers do not have filters, which can cause impurities to be dispersed in the air with the mist. If you have a dust allergy or respiratory problems caused by airborne pollutants, you should opt for a humidifier with a reliable filtration system.

The majority of the ultrasonic humidifiers lack filters because they use special technology to release the moisture in the air, which doesn’t require a filter.

Warm mist humidifiers remove many of the impurities by boiling them, so they are probably the most suitable type for homes where there are people with allergies, respiratory problems, or weak immune systems.

In any case, you will need to wash and sanitize the water tank and unit at least once a week to be on the safe side.

Room size coverage

In order to ensure that the air in the room or area is adequately humidified, you should opt for a humidifier that has a capacity for it. it is a good idea to choose one which has a larger capacity than the space you have designated, to stay on the safe side.

Noise level

Pay attention to the noise level of the humidifier you are about to buy because you don’t want to end up with a device that will disturb and annoy you more than help you with your sinus problems.

Choose a whisper-quiet humidifier if you are going to use it in your bedroom or the nursery. Or opt for the quietest possible one if you are sensitive to noise.


If you have sinus problems or even if you are perfectly healthy, you wouldn’t want to deal with a humidifier which is hard to clean, right?

Humidifiers do require regular cleaning because if they are left dirty, they can become ideal breeding grounds to mold, bacteria and other potentially harmful microorganisms which can make your condition worse.

Look for a humidifier with a tank with a wide opening, which is easy to reach in and clean. Also, all the parts through which the water passes should be able to be disassembled and cleaned too.

Ease of use

Choose a device that you will feel comfortable using, adjusting and setting.

This will make life easier for you, especially if you decide to turn it on or adjust the settings in the middle of the night.


Choose an appliance that will fit the space you have allotted for it. If you want one which you can hold on your nightstand, then opt for a compact one. These though are less powerful and will not be as efficient if your bedroom is too large.

A portable humidifier for a whole room may take up more space, but it has a higher capacity and will be able to achieve the humidity levels you want.

Whole-home humidifiers are designed to fit into most standard furnaces but you should check yours just in case to make sure that you are getting a properly sized one.

Keep in mind that you will need to keep the humidifier away from furniture, cabinets, and others which can be damaged by the mist or vapor if they are too close to the unit.


We all wish that the appliances we invest our money in will last an entire lifetime, but unfortunately, this is rarely the case.

This is why you should choose a humidifier that is sold with a more extended warranty.

This will give you peace of mind that any problem which occurs during the warranty period will be taken care of without you having to pay for repairs or parts.

Always check what the manufacturer has included as covered by the warranty, and which types of problems are excluded from it.

Extra features

The different humidifiers have different bonus features, some of which are pretty useful for people battling sinus problems.

One useful feature is the aromatherapy or essential oil one. This means that you can use the humidifier for inhalations of eucalyptus, or other essential oils and medical vapors, which help relieve congestion, colds, and sinus inflammations.

Also, you can use the aromatherapy feature for relaxing or creating a more welcoming atmosphere in your home.

Another feature you should look for is the automatic shut off option. This is for the safety of the humidifier, as well as for your own safety.

This feature will ensure that the unit switches itself off automatically if low water levels are detected. This can help avoid the humidifier from burning, overheating, or causing a fire in your home.

You may also want to opt for a humidifier that has a remote control. This will allow you to adjust the settings from a distance which is very useful when you are working, relaxing or sleeping.

A built-in humidistat and sensor will enable the humidifier to detect the humidity levels itself and then shut itself off when the limit is reached, or turn itself on when the humidity levels start to drop.

Many of the new humidifiers also can double as nightlights, which is an excellent feature if you will be using the unit in your bedroom, your child’s room, or the nursery. But make sure you choose one which can have its light switched off if you are a light sleeper and do not want to be disturbed by indicator lights.

How to relieve your sinus problems

A humidifier is an excellent first step to start battling your ongoing sinus problems, but there are other things which you can do to relieve the pain and discomfort from a sinus infection, and reducing the symptoms of chronic sinusitis.

Here are some of the remedies and treatments you can try:

Staying hydrated

Not only does it help to breathe moister air when you have a sinus infection, but you will want to drink a lot of water, which will help you flush out the viruses from your body.

Also, hydrate your nose and sinuses by using an over-the-counter or home-made saline nasal spray. It doesn’t contain any harmful chemicals and can help break up the congestion and allow you to breathe easier and sleep better.

Use steam to break up the congestion. Taking a hot shower or bath or inhaling the steam from boiling water (from a safe distance) can do wonders for sinus problems.

Warm mist humidifiers and vaporizers can be used for these periodic inhalations.

Use essential oils

You can rub a drop or two of eucalyptus oil on the roof of your mouth for congestion relief. After that, drink a glass of water.

You can also add the eucalyptus oil to the essential oils tray of your humidifier, so you can inhale it over time, as the warm mist is released.

Other essential oils that are known to relieve sinus problems include peppermint, thyme, tea tree, lemon and lavender.

Do nasal irrigations

Use a neti pot to ease the symptoms of sinusitis. This is especially helpful if you suffer from chronic sinusitis.

The general directions for using a neti pot are to fill it up with a saline solution, include your head over the sink and carefully pour the solution down one of your nostrils. After that repeat the process with the other nostril.

You can actually make your own homemade saline solution by mixing the following common ingredients:

¼ pint of water

¼ teaspoon of salt

¼ teaspoon of baking soda

Use warm compresses

By applying warm and moist compresses in the area around your nose, eyes, or cheeks where you feel the pain and pressure can help alleviate it. It can also help improve the drainage and clean the nasal passages.

OTC medications

If home remedies don’t seem to be helping, you should speak to your pharmacist about available over-the-counter medications. Sudafed is an efficient OTC decongestant that can relieve your symptoms by reducing the inflammation and swelling of a sinus infection, as well as the drainage from them.

You can treat sinus pain with aspirin, ibuprofen, or acetaminophen, commonly available as Tylenol, Motrin or Advil.

If your congestion is a result of an allergic reaction, then taking OTC antihistamines may alleviate the symptoms.

Go to the doctor for a prescription

If your sinusitis doesn’t seem to be getting better with OTC medications, it may be time to ask your doctor for a prescription.

What kind of medication will be prescribed to you depends on whether you have a bacterial sinus infection or a virus.

Symptoms of sinus infections

Some of the most common signs that you have a sinus infection include:

  • Nasal congestion
  • Mucus coming down the throat from the nose
  • A green-colored discharge from the nose
  • Tenderness or pain on the bridge of the nose and under the eyes
  • Mild pain in the temples or forehead
  • Fatigue
  • Fever
  • Cough
  • A bad taste in the mouth

Preventing sinus infections

The best way to stay clear of sinus problems is prevention. This is why you need to know what the common causes of sinus infections are.

These include:

  • Common cold
  • Allergen exposure
  • Hay fever
  • Rhinitis, which is not caused by allergens
  • Air pressure shifts and changes

In order to prevent these, you should do the following:

  • Maintain good hygiene and wash your hands after going out, using public transportation or after being in crowded places
  • Make sure you get all required immunizations in time
  • Do not come into contact with people with colds or those suffering from upper respiratory infections
  • Do not smoke, and do not go to places where there is secondary smoke
  • Get sufficient rest if you feel like you have a cold
  • Use a proper humidifier at home and your office
