I live with a mild respiratory condition, so I’m no stranger to clogged sinuses. My sinus-related breathing problems get particularly bad during dry air.
My humidifier has really helped relieve my sinus pain and congestion!
If you suffer from sinus issues, you might wonder how a humidifier can help you.
In this guide, I will show you exactly how to use humidifiers to help relieve sinus issues and breathe more freely in your home.
Will A Humidifier Help Relieve Sinusitis? (Solutions Explained)
Humidifiers are great at relieving a wide range of sinus symptoms!
A humidifier likely won’t cure the root cause of your sinusitis if it’s due to a viral or bacterial infection.
However, maintaining appropriate humidity levels in my home has helped me clear my nasal passages and suffer from fewer sinus issues.
I’ve listed here the major sinus issues that a humidifier can help with.

Humidifiers Alleviate Sinus Infection Symptoms
As I mentioned, a humidifier can’t cure a sinus infection caused by a virus or bacteria.
However, it can help mitigate the sinus symptoms caused by infections!
If your indoor air is dry, the snot and mucus your sinusitis produces won’t drain well.
The mucus buildup in your nasal passages can lead to further sinus issues and a stuffy nose.
By adding moisture to the air through water vapor, a humidifier can thin the snot and mucus inside your nose and sinuses.
When all that gross stuff starts to flow properly, it’s much easier for me to blow my nose clear.
Reduced Sinus Pain Due To Moisturized Nasal Passage
If you live in a dry climate like I do, sinus pain can be a regular, unwelcome guest.
Dry air causes cracking on nasal membranes, which is painful and can lead to bleeding.
A humidifier has made my sinuses a lot less painful. The increased humidity levels it creates moisten my sinuses and keep them from cracking.
I recommend buying a cheap hygrometer to ensure your home has a humidity level between 30-50% for ideal relief. (1)
Hygrometer only measures the relative humidity. Humidistat is a built-in device on humidifiers that measures AND controls humidity.
Humidifiers Soften Mucus To Reduce Sinus Congestion/Headaches
I often get headaches when dried-up mucus builds in my sinuses. A humidifier has helped relieve my headaches better than any amount of Advil.
Sinus headaches often stem from congestion when mucus dries up on your membranes.
As I mentioned, humidifiers thin your nasal secretions and allow you to clear your airway.
As a result, you’re much less likely to experience a throbbing sinus headache.
Improve Sinus Drainage And Relieve From Postnasal Drip
Sinus drainage, also called postnasal drip, can be annoying and uncomfortable. For me, it’s particularly bad at night.
I hate waking up coughing when mucus drips down my throat.
A humidifier can once again help by thinning the mucus. Any sinus drainage can then flow more freely, instead of moving in horrible clumps that make you choke.
I also advise propping your pillow to keep the thinned snot from getting into your throat.
Hydrates Dry Sinuses And Improves Snoring
Your sinuses may dry for any number of reasons, from a common cold to generally dry air (like in my home region).
Dry sinuses can crack, bleed, be painful, and cause irritation and coughing.
Humidifiers help keep your nasal passages moistened by increasing the relative humidity in your home.
Not only does this provide relief for the sinus symptoms I mentioned, but it can also keep you from snoring!

Relieves Sinus Pressure And Inflammation
Sinus pressure is often due to blocked nasal passages, caused by your sinuses being unable to properly drain.
This can lead to painful inflammation in the head, nose, and face.
Once again, keeping your sinuses hydrated by using a humidifier can help loosen and drain blockages.
You can then clear your nasal passages more easily and relieve the uncomfortable and painful pressure.
How Different Humidifier Types Help Your Sinuses?
There are various types of humidifiers and some of them are better for sinus health than others.
Here’s my breakdown of the most common humidifiers and how they help with sinuses.
Ultrasonic Humidifiers – Recommended To Use With Distilled Water Only
Ultrasonic humidifiers use a plate vibrating at very high speeds to turn water into a cool mist.
I love these units because they’re very quiet and effective at raising humidity levels.
However, ultrasonic humidifiers don’t have filters.
If you use tap water in them, they could emit contaminants that make your sinusitis worse.
I strongly recommend using only distilled water in ultrasonic (or any other) humidifiers.

Evaporative Humidifiers – Noisy But Offer A Filter To Trap Impurities
Evaporative humidifiers are cool mist humidifiers that draw water from the tank into a wicking filter.
An electric fan pushes cool air over the wet wick to produce water vapor.
The wick filter traps impurities in the water, which can help relieve sinus issues and allergy symptoms.
They are a bit noisy, though, so take that into account if you plan to use one in your bedroom.

Impeller Humidifiers – Only Use With Distilled Water For Sinus Issues
An impeller humidifier is a cool mist humidifier that creates vapor by disturbing water with a rotating disk spinning at very high speeds.
It functions similarly to an ultrasonic humidifier, which means it shares the same pros and cons. Always use distilled water instead of tap water in these units.
Warm Mist Humidifiers – Great For Sinus Issues But Are A Safety Hazard
Warm mist humidifiers — also called steam vaporizers — use heat to boil water and create hot steam.
This warm steam can quickly relieve congestion and soothe dry sinuses and pressure.
I recommend a warm mist humidifier for relieving sinus problems — with one caveat.
Don’t use these units around pets or children as the hot steam is a safety hazard.
Whole-House Humidifiers – When You Want Your Entire Home Humidified
Whole-house humidifiers (or central humidifiers) attach to your heating system to humidify and improve indoor air quality throughout your home.
If you live in a dry climate, they can be an excellent option for relieving sinus discomfort in all rooms with humidified air.
However, they are pretty expensive and difficult to maintain.
Precautions To Take When Using Humidifiers For Sinus Relief?
Humidifiers can provide sinus relief — but they could also make your issues worse if you use them incorrectly.
Here are my best tips for getting the most out of your humidifier without putting yourself at risk:
Common Causes Of Sinusitis When At Home
Knowing what causes your sinus issues can help you decide whether and what kind of humidifier can help you.
I’ve listed the most common sinusitis causes here and explained whether a humidifier is good for them.
Dust In The Air
Dust is very bad for my sinuses, as it causes me irritation and dry membranes. A humidifier can help reduce airborne dust.
The added humidity condensates around dust particles and drags them to the floor, making it easier for me to vacuum them up.
Mold Due To Excessive Humidity
Mold is scarily common and can pop up in humid bathrooms, under sinks and carpets, or in leaky ceilings and walls.
Over humidification can make things worse and introduce myriad of new health issues.
I strongly recommend buying a hygrometer or humidistat — especially if you live in an already humid area — to avoid raising moisture levels too much and encouraging mold growth.
Pet Fur And Dander
I love my dog, but our pets can, unfortunately, contribute to sinus problems by shedding fur and pet dander.
A humidifier can help with this issue by weighing down airborne hair and dander and by relieving dry skin.
Cleaning Products And Their Chemical Composition
Some cleaning products can wreak havoc on our sinuses! Some of us (like me) are sensitive to strong detergents and scents.
A humidifier won’t do much to help with this issue, so I suggest swapping to milder or all-natural cleaning products.
Pollen From Houseplants & Flowers
Plants and flowers instantly add life to any space, but they can also contribute to sinus problems with their pollen.
Like with dust, a humidifier can bind and weigh down the pollen to get it out of the air and your sinuses.
A humidifier does not clean the air. They are only designed to add humidity which improves the air quality, but does not necessarily clean it. For cleaning the air, you will need to procure an air purifier.
What Can I Put In My Humidifier For Sinus Issues?
I don’t recommend adding anything but distilled water to your humidifier. Medications, scents, and essential oils can damage the unit.

Can You Put Vicks In A Humidifier?
You can’t put Vicks products in a humidifier. They are topical treatments that aren’t meant to be inhaled and can cause respiratory issues.
What Type Of Climate Influences Sinus Problems?
Very dry and very cold climates can trigger sinus problems. A humidifier can add moisture to the air in these environments and relieve sinus issues.
Do Cool Mist Humidifiers Help With Congestion?
Cool mist humidifiers can help with congestion. A warm mist humidifier may loosen mucus more effectively, but a cool mist unit can still be a great option, especially in a hot climate.
What Is The Difference Between A Vaporizer And A Humidifier?
Humidifiers add moisture to the air by breaking water into a cool mist. A vaporizer boils water to create hot steam instead.
