Sinusitis is a problem associated with a lack of sufficient humidity in the air. Symptoms include nasal discharge, sore throat, and hoarse voice, throat irritation and coughs, nasal pain and congestion, just to mention a few. Sinus problems are more common during cold winter months as the air is usually dry at this time of year. Breathing this dry air has been associated with sinus irritations, cracked lips, and even dry eyes. The solution to these health issues is to moisturize the air in your home, and the best way to do that is to use the best humidifier for sinus problems.
The factors we considered in our selection include runtime, coverage area, tank capacity, mist type, and sound level. Runtime is crucial since you need to know how long a device can work before needing to be refilled. Knowing the coverage area will let you select a perfect model for your room size, while the noise level will determine if the device can be used during the night relieving your symptoms without waking you up.
Your next challenge is choosing the best humidifier for your needs, but luckily you can find the right device in this post. We spent more than 72 hours researching and comparing 30 different humidifiers and finally settled on the best eight models that are specially intended for sinus problems. Since these devices come in all shapes and sizes, we’ve included in-detail product reviews and a comprehensive buying guide to help you choose the best humidifier for sinus problems. But before we go any further, check out the table below for our ratings and nominations for the select products in this post:
More features: filterless design; blue LED nightlight
The Everlasting Comfort Ultrasonic Cool Mist Humidifier is arguably the best cool mist filterless humidifier for sinus problems. The first thing you notice is a sleek, modern design with a small footprint that will allow you to place it on your bedside table. The unit boasts a 1.6-gallon water tank, which can last up to six days before refilling, and a powerful mist output of 270ml/hr. This device has the ability to humidify rooms as large as 400 square feet and maintain moisture levels above 43%. This is the recommended humidity level for a healthy environment, free of disease-causing viruses and allergens.
Being an ultrasonic humidifier, this unit utilizes high-frequency sound vibrations to produce a fine, cool mist that is then expelled into the room. Still, the operation is whisper-quiet, and so it won’t disturb conversations or a deep night’s sleep. There’s no water filter included, meaning the unit requires cleaning once in a while in order to remove mineral deposits and prevent mold buildup. The good thing is, you don’t have to incur expenses purchasing and replacing filters as is the case with other models.
The inclusion of an oil diffuser is no doubt a bonus. Just add a couple of your favorite essential oil drops and enjoy the aroma that comes with the healthy moisture. Try peppermint and eucalyptus oils as they also help in soothing the throat and coughs. Another useful feature is the “auto shut-off”, which automatically stops operation when the water level is very low. A built-in LED night light also indicates if the humidifier is working at night.
Overall, the Everlasting Comfort can help decrease the risk of illnesses, relieve dry, irritated skin, and dry nasal passages. And you don’t have to pay an exorbitant price for this one.

Having seen our select humidifiers for sinus problems, it’s time to know the essential features to consider before buying one. This buying guide will also answer some of the common questions about humidifiers.
Features to consider while choosing a humidifier for sinus problems
We have already mentioned plenty of them in the product reviews, but in this section, we elaborate on the significance of each feature. Keep in mind that not all bells and whistles are worth the extra money as some may have no major impact in the long run.
Every humidifier has a specific runtime, basically, a number that tells how long the unit can produce mist. This depends on a number of factors including the tank capacity and mist setting. Generally, the more water in the tank, the longer the runtime.
If a humidifier has one setting, then its mist output is constant, and it’ll likely run for the specified amount of time. However, if it has more than one mist mode like the Levoit LV600HH humidifier, then the runtime will depend on the selected mist output. The highest mist setting expels more mist than the medium and low setting. Thus you can expect the tank to run out much quicker.
A unit that offers 10-12 hours of runtime will definitely provide healthy air for a whole night. On the other hand, a portable model to be used on the go, such as the Fancii Cool Mist Personal Mini humidifier, may have a runtime of just four hours, yet that’s still enough for its purpose.
Water tank capacity
Basically refers to how much water the tank can hold. Smaller units have smaller capacities, while larger models such as the AIRCARE MA1201 can hold a lot more. We’ve already mentioned that the tank capacity is a major factor in the unit’s runtime. Not everyone wants the largest tank though. It comes down to your needs. Do you want a humidifier that can run for 2-3 days without refilling or you don’t mind doing it every day?
Note that the more water stays in the tank, the more the chances of mold growth are. So as much a large tank sounds great, consider the inclusion of filtration systems that can trap lime scale and other particles. That way you can rest assured the air coming into the room is free of allergens and bacteria. The Pure Enrichment MistAire Eva with its air filtration capability is a perfect example.
Who doesn’t want their air fresh and filled with nice aromas? Well, unless you are allergic to fragrances. Even so, aromatherapy option is not a necessary requirement for humidifiers. Aromatherapy is a plus if available, but it doesn’t make a unit without it less a humidifier. It’s something you find in the best rated personal humidifier for sinus and allergy problems like the Everlasting Comfort Ultrasonic humidifier. This model includes an essential oil tray where you can add your favorite oils to enhance the room’s air quality and your overall mood.
Indeed, you want the humidifier to supply healthy moisture in your room, but it should not be a nuisance. You can’t sleep with the unit humming loudly near your bed, or even have a conversation with a loud unit next to you. So pay attention to the sound level of the humidifier you want to buy.
The models on our list have sound ratings of 35 decibels and below, meaning they are all whisper-quiet. The Fancii Cool Mist Personal Mini Humidifier is the quietest humidifier on this list with less than 15 decibels of sound, which is equivalent to a pin dropping.
The first thing you need to decide is the size of the area you are aiming to cover and probably the number of rooms. Apparently, a small humidifier will take very little space on the shelf, but it won’t be ideal for humidifying a considerably large area.
Portable humidifiers like the Pure Enrichment MistAire Silver Ultrasonic Cool Mist Humidifier are only ideal for single rooms such as a bedroom. A mini unit like the Fancii Cool Mist Personal Mini Humidifier is even excellent for traveling as it can easily sneak into a bag.
Room humidifiers are larger and give you plenty of options to choose from that will efficiently moisturize a multi-room area of 600 – 1200 square feet. The Levoit LV600HH falls in this category.
Then there are whole house humidifiers that are intended for humidifying an entire home, as long as the doorways are left open. The AIRCARE MA1201 is a great example, measuring 21.5 x 23.5 x 16.5 inches and with maximum coverage of 3600 square feet.
Generally, the larger the area you need to humidify, the larger the unit you need.
Although you wish your humidifier could last a lifetime, sometimes improper handling during shipping may cause defects. There could also be a manufacturing default. These kinds of issues need to be covered so that you don’t end up paying for repairs that you are not responsible for.
Some of the models we’ve reviewed here come with from 12-month to two-year warranties. Others like the Pure Enrichment MistAire Eva have additional incentives such as a 45-day money back guarantee. Once in a while, you will find models with extended warranties like the five-year warranty on the Pure Enrichment MistAire Eva model.
Ideally, the more extended the warranty, the safer you feel about the product. Be sure to find out what is and what’s not covered by the warranty.
A few bonus features will make your unit more worthwhile. For instance, a timer setting will allow you to run the humidifier for a certain number of hours before it automatically shuts off. At least every unit has the auto shut-off feature to avoid the risk of running dry, which can be very dangerous.
If the humidifier comes with remote control, then it means you can input your settings from the comfort of your couch. Another useful feature is a humidistat, which will measure the actual humidity level, and once it reaches a set limit, shuts off. A very convenient feature for accuracy.
You just need to compare the extras and decide the ones worth splashing a little more money.
How to fight your sinus problems
Sinus infections tend to go away after a few days even without any prescribed medications. In cases where your symptoms can’t go away, or they keep coming back, you may try the following methods to combat sinusitis:
Use a humidifier to moisten the air in your home and keep humidity at optimum levels.
Try over-the-counter painkillers such as Acetaminophen and Naproxen to relieve sinus pain, reduce high fevers and inflammation.
Use OTC nasal decongestant spray to alleviate congestion and provide relief. This is especially effective in the early days of a cold but usually recommended for a maximum of three days.
Use a saline nose spray to reduce sinus swelling and help break the mucus that’s blocking your nose. Be sure to seek advice from a pharmacist regarding this method.
For a more natural approach, inhale the steam of boiling water (not hot) for quicker relief. Alternatively, relax in a steamy bathroom after a hot shower. Stuffy and congested noses respond well to moist air.
Both have their pros and cons. For instance, warm mist can slightly warm up a room if it’s cold. The water inside is initially heated in order to kill bacteria and make the mist healthy and safe to inhale. But, a warm mist humidifier is not recommended for homes with children because the hot water inside it could pose a serious danger to children.
Cool mist humidifiers are ideal for homes with children, use less electricity than warm mist models, and they’re less expensive than their warm counterparts.
Depends on the humidifier and if it’s used correctly. Most of them are safe to use in a nursery, with the exception of warm mist or steam humidifiers. Just ensure to place it further from the baby’s bed or play area as too much moisture can cause discomfort.
The unit can overheat or short-circuit, and this can cause a fire or explosion. Again why the “auto shut-off” is such a crucial feature of any humidifier.
A humidifier could mean the difference between comfort and pain for anyone experiencing sinus problems. All the models above are great life-savers, but there are a few that have gone over and above expectations.
Our ultimate choice is the Everlasting Comfort Ultrasonic Cool Mist Humidifier. This sleek unit offers unmatched runtime up to 50 hours alongside a generous tank capacity of 1.6 gallons. With 400 square feet coverage, this comfortably serves most large rooms plus it’s whisper-quiet.
Our runner-up is the Levoit LV600HH. Perfect for multi-room use owing to its 735 square feet coverage, this unit also includes the aromatherapy option. The supplied remote control and cleaning brush are amazing accessories too.
The Pure Enrichment MistAire Eva is another worthy mention. With its antimicrobial filter, three mist modes, whisper-quiet operation, and decent tank capacity, this unit has some awesome features for the money.
