Sinus problems can be caused by many reasons. Some are caused by bacteria and viruses while some are caused by environmental factors such as excessively dry air. Sinus problems caused by bacteria and viruses are more commonly known as sinusitis which is an infection of the sinus while excessively dry air would cause dry sinuses. 

SInus problems can lead to dry nose passages, discomfort during breathing, nosebleeds, stuffy nose, thick discharge from nose and tenderness around the eyes, cheeks and forehead. If these symptoms sound familiar then you may have sinus problems!

One really simple way to reduce your sinus problem is to make sure your home humidity is not too low. Using a humidifier would easily maintain your home humidity at an optimum level and help tremendously with your sinus problems.

HuPro Premium Ultrasonic Cool And Warm Humidifier

Best Overall Humidifier For Sinus Problems

Product Overview

  • Coverage area: up to 500 sq. ft./ 47 sq. m
  • Water tank capacity: 1 gallons /4 litre
  • Running time: 30 hours
  • Dimensions: 14” x 11.2” x 10.5”
  • Weight: 8.48 lb

The HuPro Premium Ultrasonic Cool and Warm Humidifier is a dual mist humidifier that can cover an area up to 500 sq. ft. with its 4 gallon water tank. This large capacity humidifier has a running time of 30 hours between refills allowing users to use it through the night without waking up to refill it. If it does run out of water during the night, the auto shutoff feature kicks in, ensuring the safety of the unit and the user. As an ultrasonic humidifier, this model is also very quiet, registering only about 30 dB on the highest speed setting. This makes it an ideal choice for babies, seniors and sensitive sleepers.

In terms of functionality, the dual mist feature allows users to choose between cool or warm mist depending on their preference for the day. The smart humidification system incorporates three types of humidity control, auto mode, constant humidity and 5 speed levels. There is also an essential oils tray for homeowners who love to indulge in some aromatherapy at the end of a tiring day.

One particular feature that caught our attention was the triple purification unit that consisted of  a ceramic filter, UV light and air ionization. The ceramic filter contains active carbon and mineral pellets that will absorb impurities from the water as it passes through the filter resulting in cleaner and fresher air. The great thing about this filter is that it never needs replacement so you never have to worry about replacement schedules or fork out additional cash for replacement filters.  Another feature that aids the cleansing of air is the air ionization. It produces 300 million cleansing negative ions per minute to decontaminate the water of fungus, virus and fungi. Combine that with an UV light that prevents odor in the water and you have a winner!

For ease of use, I really love that it is a top refilling humidifier because that is just so convenient for homeowners to refill without much effort and without any mess. The water tank also has an extra-wide opening for easy filling and cleaning

One gripe I have with this humidifier is that the mist shoots straight up and some droplets will just drop down and wet the surface the humidifier is sitting on. It would have been better if the mist can be directed away from the humidifier and further away. It still does a good job but users will need to make sure they protect the floor with a rug or a tray so that water does not collect. Besides wetting the floor, this also causes the humidistat to register a higher humidity than what the room really is.


  • Quiet
  • Auto shut off feature
  • Triple purification feature
  • Good coverage area
  • Easy to refill water and clean


  • Tends to wet the surface/floor that it sits on
  • Humidistat can be inaccurate because the mist is saturated near the unit

What the fans love: “Easy to clean due to the removable water bin. Virtually silent. No fans or other noise. Love the little warming tray to put some scented oil. Keeps the master bedroom humidity at 45% ( up from 33% naturally ) and has solved respiration problems due to dry air. Bought a second one for the office.”

Best Humidifier For Sinus Problems Buyers’ Guide

Is Dry Air Affecting My Sinuses?

Cold dry air leads to dehydration at the surfaces of our respiratory systems and surface dehydration causes a wide range of harmful effects to our airway. These effects include degeneration of cells and over-stimulation of the immune system leading to heightened responses to the cold dry air. These heightened responses manifest as sinus problems such as nosebleeds, stuffy nose and so on.

When the airway surfaces are dry, it also increases the adherence of bacteria to the surface and allows greater penetration of foreign particles. All these further contribute to more symptoms of sinusitis.

Besides an increased susceptibility to bacteria, viruses also thrive in low humidity conditions. Viruses demonstrate the greatest activity and survival at a low relative humidity level of 20% which decreases rapidly when the humidity level is increased to 60%.

Is Humidifier Good For Sinus Problems?

Yes! A resounding Yes! Humidifiers work wonders for sinus problems. 

Arundel’s study in 1986 on indirect health effects also tells us that there is increased incidence of respiratory diseases in winter. This is especially so when the humidity level goes below 20%

Therefore, having a humidifier would be extremely useful as it can correct the humidity levels during the colder months which are also drier usually. 

As mentioned above, bacteria and viruses are also more active and virulent when the environment is dry. Their activity is especially pronounced when humidity levels drop below 20%. Using a humidifier to increase the humidity levels predictable is the easiest way to prevent these harmful pathogens from messing with our sinuses.

What Is The Best Humidity Level For Sinus Problems

The most ideal and most comfortable humidity level to aim for is between 40% to 60% relative humidity. Studies have shown that this is the most optimum range of humidity for human health and comfort. 

While it may seem logical that higher humidity will be better for sinus health as it can prevent dry sinuses, there are also issues associated with excessively high humidity.. Excessive humidity can cause other problems like increased growth of mold, fungus and viruses.

What Type Of Humidifier Is Best For Sinus Problems

Humidifiers can be broadly categorized into 4 main types

  • Evaporative
  • Ultrasonics
  • Steam Vaporizer
  • Air washer

While each type of humidifier has its pros and cons, homeowners will be glad to know that there are no specific type of humidifiers that are just for sinus problems. In other words, all 4 types of humidifiers can be used if you are suffering from dry eyes. However, each type has their own unique selling points that may be applicable to other aspects of your life. Do read on to find out more. However, if you need answers fast, you can just check out the table of comparison below!

Comparison of humidifier types


In essence, evaporative humidifiers work by evaporation of the water in the humidifier and releases it as a cool mist. Inside most evaporative humidifiers is a wick that absorbs the water in the humidifier. A fan then evaporates the water in the wick giving us water vapour and increasing the humidity in the room. For those who are unfamiliar with what a wick is, it is a porous cylindrical structure that has a large surface area which allows maximum water absorption and water evaporation.

The wick also acts like a filter to filter out any impurities or contaminants in the water being used in the humidifier. Due to the presence of this wick filter, the type of water used in an evaporative humidifier is less restrictive than an ultrasonic humidifier which does not use a filter. Generally, you can use normal tap water in an evaporative humidifier without any issues. Wicks are usually quite large in size and therefore you will find that most evaporative humidifiers are bulkier in size and also heavier.

Another advantage of evaporative humidifiers is that it can never over-humidify the air because it works by evaporation. If the ambient air is already saturated with water, evaporation will not be able to occur no matter how much the fan blows at the water. 

The purchase cost of an evaporative humidifier is usually the lowest among the different types of humidifiers but the operating cost is the highest from the replacement of wicks and filters. It is recommended that filters be replaced every 3 to 6 monthly depending on the usage of your humidifiers. Different humidifiers may also have different recommendations so it would be best to check in with the manufacturers if you are intending to get an evaporative humidifier.

Evaporative humidifiers also tend to be louder due to the running fan that is used to evaporate the water in the humidifier. Some humidifiers can register noise level up to 50 dB at their highest speed settings. If you are intending to use your humidifier in your bedroom or if you are very sensitive to noise then an evaporative humidifier may not be for you.

Steam Humidifiers/Vaporizer/Warm Mist

Vaporizer humidifiers basically boil the water in the humidifier into steam before releasing it into the air. As you can probably imagine, the mist from a vaporizer can get quite hot and hence it is also known as a warm mist humidifier. Vaporizer or warm mist humidifiers are very popular among homeowners suffering from allergies or asthma because the warm mist usually has a more soothing and comforting effect on sensitive airways than cool mist humidifiers. 

Due to the heating of the water in the vaporizer, most bacteria in the water are also eliminated and the mist coming from these humidifiers are generally cleaner and healthier compared to an ultrasonic humidifier. 

Vaporizer steam humidifiers typically do not come with fans and hence there are no moving parts. Therefore they are usually silent and fit the bill for a quiet humidifier. 

Vaporizers typically do not have filters and can be considered if you need a filterless humidifier.

Ultrasonics Humidifier 

An ultrasonic humidifier is a nebulizer that uses high frequency vibrations to break water down into ultra-fine droplets which then get released into the air as a mist. Depending on the specific model, the mist may be a cool mist or a warm mist. An easy way to see if a humidifier is an ultrasonic humidifier is to see if there is a mist plume coming out from the model. If there is a mist plume, it is usually an ultrasonic humidifier. 

An ultrasonic humidifier does not have a wick like an evaporative humidifier and typically does not have any filter as well. As such, they are usually less bulky and lighter. However, because of the lack of a filter to absorb impurities and contaminants, it is recommended to use either distilled water or filtered water in the humidifier. If hard water such as tap water is used, ultrasonic humidifiers may dispel white dust into the air due to the mineral contents in the water. 

Ultrasonic humidifiers have the highest humidity output among all the types of humidifier because it actively breaks down water into fine droplets and forcefully discharges it into the air. Theoretically, there is the risk of over-humidifying the air but most humidifiers have an inbuilt humidistat to prevent that from happening.

In terms of price, ultrasonic humidifiers usually cost more upfront but have the lowest operating cost because there is no need for filter replacement every 3 to 6 months. 

Ultrasonic humidifiers also do not typically come with fans and do not contain much moving parts. They are usually pretty quiet during operation and generally do not register noise levels above 40 dB. 

 Air Washer

Air washers are 2-in-1 appliances that combine a humidifier and an air purifier together in one unit. Besides being able to control the humidity in the air, air washers also clean the air by filtering large particles, pollen and contaminants from the air. With a combination of these two functions, the indoor air quality in your house will be maintained at a comfortable and healthy level. For those suffering from asthma or allergies, this might be your best bet yet.

In order to perform the air purification and humidification, airwashers usually have inbuilt fans and discs. These moving parts contribute the higher noise levels that are seen with airwasher.

Is Cool Mist Or Warm Mist Better For Sinus Problems

If I have to choose between the two types of mist for my humidifier, I would go with warm mist. Warm mist is generated by boiling water to get steam and this process of boiling can remove harmful bacteria from the water before releasing it into the air. Since the humidifier does not have a humidifier to remove pollutants, boiling it helps to reduce some of the bacteria load that may be in the water.

That being said, do not get overly worried because you own a cool mist humidifier now. If you use clean water and maintain your humidifier regularly, there would not be much harmful pollutants or bacteria in your water anyway.

Another reason for favoring warm mist is that it is generally more comfortable for homeowners who suffer from sinus problems and other allergic conditions. 

According to research, the most ideal room temperature for people suffering from respiratory diseases is between 64.4°F / 18°C to 68.8°F / 21°C. Studies show that people who lived in homes in which the ambient room temperature was at least 68.8°F / 21°C for at least 9 hours per day had significantly better respiratory health. 

“…increasing warmth leads to improvements in health for most respiratory disease … warmer temperatures improves the respiratory symptoms of children with asthma”.

Philippa Howden-Chapman, Director of the Housing and Health Research Programme, University of Otago, New Zealand


For those  intending to use the humidifier in different rooms in the house or transporting  it between your office and home then portability becomes an important consideration to watch out for. 

Evaporative humidifiers and air washers are usually bulkier and heavier due to the extra components they have in their bodies and this reduces their portability. These units may be better suited for a fixed position in a house or room. 

Ultrasonic humidifiers and vaporizer are generally more compact and lighter and can be transported between rooms easily. 

Ease Of Maintenance

This refers to the ease of refilling water and the ease of cleaning. Most humidifiers will require a refill of water every 24 hour depending on the capacity of the water tank. For something that you have to do frequently, it makes sense to find a model that allows easy refilling that is fast, efficient and neat. Usually, a top refill model is easier to do refilling as you just need to cover the top lid and pour in water. Generally, bottom refills tend to be messier and more of a hassle.

Humidifiers usually need a good thorough wash once every week. Depending on the model of the humidifier, the cleaning may take anything from 10 minutes to 30 minutes. When choosing a humidifier that is easy to clean, avoid units with many components or units with many small parts that are difficult to access. Some models come with specialized brush to allow users to reach difficult to access areas. The water tank should have a large access hole which allows the users to place the whole hand in for easy scrubbing.

If a humidifier cannot be cleaned properly, there will be buildup of lime, mold and fungus and these particles can get released into the air when the humidifier is working. 

When choosing a humidifier for something so sensitive such as the sinuses and nose, definitely go for a unit that can be cleansed easily and thoroughly. This ensures that the water that is released is clean, fresh and healthy. 

Running Time

For homeowners looking for a humidifier to use overnight during their sleep, the wise thing to do is to find a humidifier that can at least run continuously overnight without the need for a refill. Homeowners can look at the running time of the humidifier when choosing their humidifier. At least 12 hours on their highest setting is recommended for overnight usage. Some units boast a long running time but only on the lowest setting. So… read the fine print!

Essential Oil Compatibility

When looking at alternative therapies, one cannot overlook aromatherapy. Aromatherapy using essential oils has gained traction in recent years for its therapeutic effects in many fields such as pain relief, mental wellness and so on. SInus problem is also one of the areas in which essential oils may come in useful. 

Lavender oil can reduce swelling of the airway and decrease the chance of bronchospasms. Eucalyptus oil and tea tree oil not only reduce inflammation but also help to loosen up sticky mucus.. Clove oil, chamomile oil and thyme oil are also excellent choices for sufferers of sinusitis.

Air Purifier Feature

For homeowners with sinus problems, the ability to clean the air thoroughly is always a plus point. Air purifiers have been found to help in relieving sinus problems in users. They can do so by removing the allergens from the air. Such allergens include pollen, dust and smoke. By removing these potential allergens there are less triggers for the homeowners who may be suffering from sinus problems.

While having a separate air purifier would work, why not get a unit which has both humidification and air purification features? Air washers are combination units that can do both well and can be a great choice for those with sinus problems or allergies.

Noise Level

Due to the cooler temperature and drier air at night, many of us frequently wake up in the morning with dry and uncomfortable sinuses and nose. Having a humidifier running overnight would help with that tremendously. Therefore, we would most likely be using the humidifiers in our bedrooms while we sleep. 

Hence, having a quiet humidifier that runs silently is crucial for us to get a good night’s rest. When choosing quiet humidifiers, ultrasonic humidifiers and steam humidifiers are usually much quieter than their evaporative and air washer counterparts. This is because there are less moving parts in ultrasonic and steam humidifiers.

Venta LW45 Airwasher Humidifier And Air Purifier

Best Humidifier with Air Purifier For Sinus Problems

Product Overview

  • Coverage area: 860 sq. ft. / 80 sq. m.
  • Water tank capacity: 2.6 gallons / 9.8 litre
  • Essential Oils Compatibility: No
  • Refilling: Top fill
  • Running time: 24 hours
  • Dimensions: 11.8” x 13” x 17.7”
  • Weight: 13 lbs

The Venta Airwasher is both a filter-free evaporative humidifier and filter-free air purifier, all in one lightweight unit. Featuring a 2.6 gallon water tank, the Venta LW45 is able to humidify dry room air while simultaneously purifying it in space up to 860 sq. ft. Using their disc technology, the Venta Airwasher is able to remove airborne pollutants down to 0.3 microns in size. For homeowners with sinus problems and allergies, this is an indispensable feature as the unit can remove dust, pollen and pet dander efficiently from the air. This effectively reduces most types of sinus/allergy triggers in the common household.

Besides being an air purifier, we should not forget that the main function of the Venta Airwasher is a humidifier. Using evaporative technology, it is able to keep the room humidity between 30% to 50% without any risk of over-humidifying the room. By keeping the room air moist, homeowners would also find it more comfortable on their nasal passages and airway. While not completely customizable like a unit with an inbuilt humidistat, homeowners can still choose the level of humidity by choosing between 3 fan settings. 

The Venta airwasher is also pretty user-friendly. It is a top fill humidifier that allows easy refilling of water into the water tank. While most humidifiers recommend the use of distilled water to prevent lime buildup or the discharge of white powder, Venta airwashers have no issues with using hard tap water. This is because they provide a conditioner to use every 7 days to prevent lime buildup. It also helps to keep the Airwasher clean and hygienic as well as improve the evaporation/humidification process by coating the Disc Stacks. Washing is also not difficult as you just need to rinse the parts under water to clean it up.

The one grip I have is the noisy fan at the highest fan setting. The noise level ranges from 24 dB to 45 dB. If used at the lowest setting, it is perfectly fine but when used at the highest fan setting, the noise level at 45 dB is the threshold at which it might disturb you and your family.

Another limitation is the higher price point of this unit compared to other humidifiers on this review. It might not be suitable for homeowners on a budget. However, if your budget allows, this is a fantastic combo unit that is well worth your buck. WIth good humidification and air purification feature, this unit is easy to use, easy to maintain and perfect for homeowners with sinus problems.


  • Purifies air down to 0.3 microns in size
  • Has conditioner that prevent lime buildup
  • Convenient. Able to use hard tap water
  • Easy to refill with top fill design
  • Easy to clean and maintain


  • High price point
  • Not compatible with essential oils
  • Noisy fan

What their fans love: “No allergies- minimizes booger’s! We bought several of these for our whole house for wildfire season and they work great. Now we live in southern AZ and humidity levels can be 3%… the venta keeps all of us moist and breathing clean air. Great product. Once I tripped on the cord and customer service helped me fix it fast. Literally the best air purifier and humidifier ever – no water spots and it doesn’t get that humid. “

Levoit LV600HH Hybrid Ultrasonic Humidifier

Best Large Room Humidifier For Sinus Problems

Product Overview

  • Coverage area: 753 sq. ft. / 70 sq. m.
  • Water tank capacity: 1.5 gallons / 6 litre
  • Essential Oil Compatibility: Yes
  • Running time: 24 – 36 hours
  • Dimensions: 11.3’ x 7’ x 10.5’
  • Weight: 4.92 lbs

The Levoit LV600HH Hybrid Ultrasonic Humidifier is a dual mist humidifier that can put out both warm and cool mist depending on your settings. Covering an area of 753 sq. fr, this is an extremely powerful humidifier that can work well in a large room. Powered by ultrasonics, this humidifier does not have a fan and is whisper quiet. It registers a mere 35 dB when it is operating on the highest setting and it is barely discernible. This makes it a perfect choice for a humidifier in a bedroom.

In terms of functionality, this humidifier comes with an auto mode which does the heavy lifting for you by automatically adjusting the humidity to a comfortable level. However, if you would like to customize the humidity level yourself, you can also pick an exact percentage and adjust it until you find your preferred humidity level.

For homeowners who sometimes forget to do a refill, you will really appreciate the auto shutoff that kicks into place when there is no more water left in the tank. For users who use aromatherapy, you will be thrilled to know there is an aroma box for your essential oils in this humidifier.

Regarding the ease of use, I have mixed feelings about the Levoit LV600HH. The remote control is a nice feature which allows homeowners to adjust the settings from the comfort of their couch or bed in the middle of the night. 

However, I really have an issue with the water refilling. The water cap is on the base of the water tank. So during a refill, you have to remove the tank, turn it upside down to fill it up and all the while dripping water everywhere and then turn it back again before inserting it back to the humidifier.

As with most ultrasonic humidifiers, it is recommended that you use distilled water or filtered water instead of tap water. Tap water is considered hard water that contains traces of mineral deposits. When used in an ultrasonic humidifier, it releases white dust into the air which may be inhaled by the user. Also, hard water will cause rapid buildup of mineral deposits in the humidifier resulting in more frequent washes. And this is one heater which does require a fair bit of work when washing. There are multiple components which require cleaning and disinfection so each wash can take about 20 minutes if you are thorough. 

All in all, a nice sleek humidifier with numerous awesome features which does a great job in humidification. However, it does require a bit more work for maintenance.


  • Large coverage area
  • Dual mist function
  • Quiet – 35 dB
  • Long running time
  • Auto shutoff function
  • Aroma box for aromatherapy
  • Touchscreen LED display


  • Requires distilled or filtered water for best results
  • Refilling water is messy
  • Washing is somewhat tedious

What the fans love: “First, I love this humidifier. We have 4 different humidifiers in our home, and this one is by far our favorite. The settings are easily adjustable, no leaks, it’s stable, it’s quiet, no problems. And the customer service is great!”

Homech Quiet Ultrasonic Cool Mist Humidifier

Best Medium Room Humidifier For Sinus Problems

Product Overview

  • Coverage area: 215 – 430 sq. ft. / 20 – 40 sq. m.
  • Water tank capacity: 1 gallons / 4 litre
  • Refilling: Bottom fill
  • Running time: 12-50 hours 
  • Dimensions: 10.2” x 6.5” x 13.3”
  • Weight: 4.8 lbs

The Homech cool mist humidifier is an ultrasonic humidifier that uses nebulization to generate cool mist for the room. Designed for small to medium sized rooms, it comes equipped with a 1 gallon water tank that can run for up to 50 hours (on the lowest settings) for areas up to 430 sq. ft. If you are like me who is always lazy to refill water then this humidifier is a great fit because you can go almost 2 days without refilling it.

As an ultrasonic humidifier, quietness is one of its selling points. It also uses weakened water flow technology and dustproof sponge to further lower the noise level to an almost indiscernible 26 dB. It is the quietest humidifier in our review and we would recommend it for use in the bedroom, nursery room or study room.

In terms of portability, this humidifier also gets a thumbs up from me. There is a convenient carrying handle that separates the water tank from the base so you can transport it easily even when it’s full or slippery. The unit itself is also very compact and lightweight. Weighing at just under 5 pounds, it is easy to bring around without any difficulties.

Other features include a 360 degree rotatable nozzle and a water-less auto shut off to protect against dry burn.

One feature that I wished for it to be changed is that it is a bottom fill humidifier. Generally bottom fill units are just more troublesome and difficult to refill. Thankfully, this unit can go pretty long between refills so it is not that painful. 

Another limitation is that it does not have an inbuilt humidistat so it cannot detect the humidity levels of the room and make adjustments automatically. Users will need to purchase their own humidistat to supplement this unit. 


  • Very quiet
  • 360 deg nozzle to direct mist
  • Lightweight and portable
  • Long running time between refills


  • Bottom fill is more troublesome to refill
  • No inbuilt humidistat

What their fans love: “I’m using this humidifier not for myself but for my tropical indoor plants. I love the 4L capacity which means I only have to refill the reservoir every other day or longer depending on the strength of the mist I select. I leave it running for around 15 hours each day. The all white design has a clean and modern look and matches with any room. The 360 degree nozzle is helpful if I want to shift the mist to other plants. The handle also makes it easy to carry the reservoir over to the sink“

Q: Do humidifiers kill airborne viruses?

A:  No. Humidifiers do not kill viruses per se. However, maintaining the indoor humidity levels between 40% to 60% will lower the survival rates of viruses. Viruses thrive in very dry (blow 20% relative humidity) or very moist conditions (above 80% relative humidity). Therefore, we always see an uptake of influenza during the winter seasons. The virus simply survives longer on surfaces and has more chances to infect people. By increasing the humidity with a humidifier, the virus does not survive as long.

Q: How often should I change my humidifier filter?

A: Depending on the model, different humidifiers would have varying recommendations for the duration between filter replacement. Most humidifiers would advise a filter replacement every 3 months. However, this can vary slightly depending on how you maintain your humidifier. If your area has very hard tap water, then you might need to replace your filter every 2 months. If you rarely use your humidifier and keep it really clean then you might get away with 4 months. 

Q: Is a humidifier safe to use around children?

A: Most humidifiers are safe around children with the exception of steam humidifiers or vaporizers. Steam humidifiers boil water to get steam which is then released into the air to humidify the room. If toppled over, the boiling water can cause severe injuries to children. Therefore, if using a steam humidifier around children, one has to keep them out of reach.
