Coughing feels terrible! I still haven’t forgotten last year and how I couldn’t sleep due to dry coughs and my painful throat and sinuses symptoms
One of the single best things I’ve done was to buy a great humidifier. But perhaps you’re wondering “What are the best humidifiers for cough relief?”
Great news – I’ve got the answers here!
In this post I’ll show you 5 of the best buys for your money along with detail and, pros & cons. I own and recommend one of the top-rated and best-selling ones, too!
There’s also some detailed info to help you understand the types of humidifiers available, how they work, and what to look for when shopping.
How to tell if you need a humidifier
Here’s a helpful scale that helps better understand humidity levels as well as good and bad ranges. A humidifier helps by bring a low level up to a healthier, much more comfortable level that helps relieve coughing symptoms.
Basically, the most important thing to know is that you need a humidifier when the air drops below a comfortable and healthy level. This is generally 30% humidity and below.
For the maximum amount of comfort (and cough relief) you’ll want to live and breathe in a range of about 30%-50% or so. Not that it doesn’t have to be any exact level, just as long as it’s within a general range.
While comfort levels vary from person to person, ultimately the best rule of thumb is to aim for about 40-50% relative humidity.
That’s great for not only adults but babies as well.
How to check humidity levels
The simplest and least expensive way to know the humidity and temperature levels in your home or office is by picking up a handy little humidity and temp gauge this popular one from Amazon. Also called a “hygrometer” in scientific terms, it just a digital meter that measures and displays air conditions in the room where you use it. I own one and absolutely love it!
Here’s the honest facts: guessing doesn’t work! To know the humidity levels around you, it’s essential to have an instrument that can measure temperature and moisture levels to calculate relative humidity accurately.
The great news is that it’s easy to solve this problem!
I use a digital humidity and temperature gauge just like this best-selling model both at home and at work. The scientific name is actually hygrometer which is a gauge used to measure humidity especially for weather conditions.
By doing so I can get an exact readout of what’s really happening in the air around me. Is it really hot or cold? Is the air dry?
Using an inexpensive meter like the one I mention here is the best solution in my opinion. The best reason is that unlike instruments of days gone by, they’re very simple to read, work quickly, and cost less than $10-$15.
What do humidifiers do?
Humidifiers work by changing water stored in a tank into a fine water vapor that fills the room. When the water vapor is released into the air the room’s humidity increases in a healthy, natural way very similar to how moisture works in nature.
Humidifiers work by adding humidity as they change liquid water into a very light water vapor which is released into the air.
They do so by using one of several methods to change liquid water (stored in a tank in most cases) into a fine mist or steam that gently floats into the air around you.
When this happens, the humidity around increases in a way that’s very similar to what happens after a rain outdoors or when you run a hot shower at home.
Warm and cool mist humidifiers use a water tank to store clean water (normally faucet or distilled water) which they slowly released into the air as a gentle mist.
However, it’s not just adding moisture that makes them so useful. There are added benefits you might not be aware of that can really improve your comfort and quality of life.
I’ll explain more as well go. There are several different kinds of humidifiers which I’ll cover in more detail – not all are effective at relieving your cough symptoms!
Don’t get stressed out, either. For the average person you won’t need to spend much to get a wonderful model that really makes a difference.
I’ll help you understand what you need and what is the best value as we go.
Types of humidifiers
You’ll find 3 major types of humidifiers when shopping:
- Warm mist
- Cool mist
1. Warm mist humidifiers
Warm mist humidifiers use electricity to generate heat and turn water into steam vapor. The vapor is released into the air slowly, increasing the room’s humidity and restoring a comfortable air condition that reduces cough symptoms. They’re also ideal for colds and congestion.
Warm mist humidifiers produce moisture as a light steam by heating water using electrical power.
Warm moisture is released into the room’s air. They’re not dangerous or extremely hot, but instead are safe enough to put your fingers or even your nose or face close to the unit.
Warm mist humidifiers are ideal for colds, congestion, and cough symptoms as well. Additionally, some models allow the use of medicated liquid additives or solid pads to offer enhanced cold or congestion relief if desired.
Just like cool mist humidifiers, however, they need to be periodically cleaned as the water tank and passageways can build up mineral and other deposits. Cleaning the device also helps make sure bacteria that might form aren’t released into the air.
2. Cool mist humidifiers
Cool mist humidifiers look very similar to warm mist models. However, they have a few distinct differences to be aware of. They don’t add heat to a room like warm mist models as they use a different method to vaporize water. They’re ideal year-round, especially in warm climate areas.
Cool mist humidifiers are a bit different from warm mist models in that they do not use heat to vaporize water. Water vapor is released at room temperature.
These types generally work using 1 of 2 methods, although many now sold are based on ultrasonic (high speed vibration) technology. Products of this type work using a very high speed nebulizer (water disturbing device) which rapidly oscillates water molecules.
This causes the water to be dispensed into the air as a fine mist.
They’re a good choice for dry climates year round and when you’d rather not add any heat into a room.
They’re also a bit more energy-efficient than warm mist models. However, the drawback is that during winter time and when colds and flu sickness is around they can’t offer the level of relief that warm mist products can.
3. Evaporative type humidifiers
Example of an evaporative humidifier set. These are “passive” (non-powered) products that do not release water vapor into the air rapidly. They rely on the natural evaporation of water. They’re not effective for cough or other dry air symptoms where you want fast and effective relief.
Evaporative humidifiers do not use electricity to rapidly increase the humidity in a room. Instead, they rely on the natural and very slow evaporation of water.
They’re not very effective for helping relieve your cough. Additionally, while they’re absolutely silent and do increase the humidity in a room over time, they’re simply far to slow to give any relief when you need it.
These are inexpensive and very simple but in my opinion a poor use of your money and you’ll be disappointed. I won’t be recommending this type.

When it comes to cool mist humidifiers and the many choices out there, this one really stand out among the competition.
The Pure Enrichment MistAire cool mist ultrasonic is one of the most popular models in the world and it’s not hard to see why!
It’s great looking, full of features, and super-simple to use. It’s almost nearly totally silent, too.
Check out some of the fantastic features you’ll get:
- Easy-to-fill water tank
- Up to an amazing 16 hours of use on 1 tank
- Near-silent ultrasonic operation
- 360 degree movable nozzle
- Optional night light
- Auto-off when water is out

It’s one of the best-selling and best-designed models I’ve had to pleasure to check out anywhere.
Left: Clean up is easy and quick using the included brush. It lets you get into those hard-to-clean areas and save time. Right: With 360 degrees of rotation possible, the unique mist nozzle is a great feature. You can easily adjust the mist direction exactly the way you want for best results.
The MistAire uses a 2-level control electronic touch control combined with an adjustable output nozzle. You’ll get custom-tailored humidification just like you want.
Rotate the nozzle to point the soothing, gentle water mist anywhere you like – there’s a full 360 degrees of rotation available. It works well and it’s really easy to adjust, too.
A beautiful blue night light is built in, although there’s no way to shut off the (dim) internal power light when the night light isn’t in use.
The night light is a great feature, but if you’re like me and are sensitive to light when sleeping, it might be a slight inconvenience, as even when the option is switched off a small amount of internal light is still produced.
However, it’s a minor complaint and the humidifier can be turned away or covered up if that’s an annoyance for you.
Refilling the empty tank is fast and easy! Just pop off the tank, unscrew the cap, and fill it with fresh, clean water. It only took me about 2 minutes get a full tank and nearly another day’s worth of use. Not bad at all!
Despite having a smaller water tank (1.5L, 0.4 gallons) it’s efficient and you’ll get up to an amazing 16 hours of use on one tank refill!
It’s excellent at relieving dry cough, colds, dry skin, and much, much more. Not only that, but it’s one of the best-made and I’m impressed with both the design and build quality.

The humidifier is easy to use and works great. Within about 20-30 minutes you’ll begin to find the humidity rising and feel relief.
The Vicks model supports using liquid Vapo Steam or VapoPads additives for extra relief from coughs, colds, and more.
Pour a small amount of medicated into the medicine cup for more cough or cold help. Alternatively, menthol pads can be inserted into the side opening to do the same as well.
It’s easy to do and really helps both children and adults feel better when dealing with difficult coughs, colds, and flu.

3. Honeywell HCM-350 Germ-Free – A fantastic cool mist purifier that stops germs dead!
The Honeywell HCM-350 Germ-Free isn’t just your average cool mist humidifier – it’s one of the most unique in that it features a built-in ultraviolet (UV) germ killing feature to prevent spreading germs.
It’s a particularly rare feature that make sure you’ll never have to worry about getting sick from your humidifier spreading germs if you forget to clean it.
Not only that but it features the same excellent build and design quality I’ve come to love and respect from Honeywell.
The HCM-350 works to produce invisible mist by using an advanced design that works using evaporative technology principles. The result is an effective, germ-free way to raise the humidity in a room efficiently.
While it cost a bit more than some of the competing models at around $55-$69 dollars, you definitely get what you pay for in terms of ease of use, performance, and maintenance that’s a breeze.
Refilling the 1 gallon tank is one of the easiest I’ve ever seen in products of its kind. There’s an easy-pull handle that truly makes removing the water tank a snap.
Just pull out the tank, fill it up, and you’re done!
The wicking filter and maintenance
An anti-microbial filter works along with the UV germ-killing feature. The filter kills 99.9% of harmful microbes that can cause sickness and can be released into the air by non-filter lesser models.
Unlike other models, the HCM-350 includes a filter to protect against minerals and other harmful contaminants your water may contain (when not using pure distilled water, which is ideal).
The replacement wicking filter uses a patented anti-microbial design that helps inhibit 99.9% of the growth and migration of mold, algae, and bacteria.
The filter can be cleaned periodically but will need to be replaced at a price of a bit less than $10 (if you pick one up from Amazon, for example).
Controls are super-simple and there’s no hassle whatsoever! Just set the main dial to 1 of 3 fan speeds and you’re done. The internal UV germ killer works on the water tank to eliminate “resting” germs and algae in the water while the wicking filter also kills germs and other bacteria that remain.
It’s one of the simplest to use despite its advanced design. Just switch the unit to 1 of 3 fan speeds and you’re done.
You’ll get up to a mind-blowing 24 hours of use out of a full tank of water!
The HCM-350 doesn’t need heat and actually produces soothing cooler water mist that’s invisible to the eye.
There’s no need to worry about over-humidifying your room because evaporative humidity can’t go beyond the largest moisture level at the room temperature.
It’s very quiet as well and won’t keep you up at night. I’m impressed and I’m sure you will be too.
The Honeywell is definitely a great little humidifier for those who want to be confident their air quality is germ-free, comfortable, and energy-efficient.
