As a respiratory disease, asthma causes inflammation and narrowing of the lungs’ airways, which are called bronchial tubes. Unlike acute diseases that affect the lungs, asthma is a chronic condition; therefore, those who have it usually experience symptoms off and on throughout their entire life. In rare cases, children can grow out of asthma when they become adults, and some people can go for years without experiencing any asthma attacks.

What Are Signs and Symptoms of Asthma?
Sometimes, the signs and symptoms of asthma begin before a full-blown attack starts. A few of the pre-attack symptoms include unusual exhaustion after physical exercise, trouble sleeping and nighttime coughing.
In the midst of an attack, coughing also occurs; however, coughing may be uncontrollable and experienced with shortness of breath, wheezing, chest tightness, anxiety, rapid breathing and even blue-tinted fingernails and lips as the person’s oxygen level decreases.
How Are Asthma Attacks Triggered?
When an event or substance triggers an asthma attack, the muscles around the airway tighten, causing bronchospasms. Then, the airway becomes inflamed and mucus production increases, both of which make it hard for the asthma sufferer to breathe. There are many asthma triggers, and these triggers are highly individualized, so they differ from one person to the next.
However, some common triggers include pollen, mold, dust, dander, certain foods like shellfish and peanuts, smoke and strong perfume. Even dry air, exercise, stress and the flu can make someone’s asthma symptoms flare.
How Does Dry Air Occur?
Winter. For those who live in regions where it gets extremely cold during this season, winter means snow and beautiful scenery. Unfortunately, winter also creates dry indoor air when the heater is running, which means trouble for asthma sufferers.
As the air gets warm inside of your house, it expands, and this impacts its ability to hold water. In turn, the relative humidity decreases.
What Is Relative Humidity?
Relative humidity is the rate of moisture the air is currently holding at a specific temperature versus the maximum moisture capacity of the air at the same temperature. When you see a relative humidity reading, it’s shown as a percentage.
For instance, a relative humidity of 30 percent means the air contains only 30 percent of the total water vapor it is capable of holding. Some humidifiers are equipped with a hygrometer, which is a tool that determines the air’s moisture level while other humidifiers have a humidistat.
A humidistat takes the moisture-reading ability of the hygrometer a step further by not only measuring the relative humidity but also controlling it.
How Can a Humidifier Help Asthma?
Even though humidifiers can’t wipe out every conceivable asthma trigger, they can keep the air moist and alleviate congestion by raising the relative humidity of the surrounding air. Depending on the type of humidifier, this appliance works by creating cool or warm mist from a supply of water the user adds to its tank.
Then, this mist is distributed out of the nozzle and into the air. The square footage of air the humidifier can moisturize depends on its delivery system, water tank size and other internal components.

What Are the Different Types of Humidifiers?
Manufacturers have developed various technologies to deliver moisture to the air, leaving consumers with multiple humidification options. Each type of humidifier works in a unique way. However, the end result is always an increase in relative humidity.
Inside of this humidifier, there is a wick filter that’s constructed from foam or cloth. This wick is designed to retain moisture. When the internal fan produces air, the air blows across the wick. As the water evaporates naturally, it releases cool mist into the air. Evaporative humidifiers don’t need a humidistat because they are able to self-regulate.
Instead of a wick and fan, an ultrasonic humidifier contains a metal plate. The humidifier generates high-frequency sound waves that cause the plate to rapidly vibrate. As the plate moves, water droplets are created, and these droplets are emitted through the nozzle in the form of cool, humidifying mist.
Like an evaporative humidifier, an impeller humidifier also has a circulating fan. However, it utilizes a diffuser instead of a wick to make water droplets. On the exterior of the humidifier, there is a revolving disc. This disc breaks up the cool droplets, so they can float through the air with ease.
Sometimes mistaken for a steam vaporizer, a warm-mist humidifier works much differently than the other three types of humidifiers listed here. Instead of cool mist, this humidifier generates just what its name suggests – warm mist.
Within the humidifier, there is a heating element that heats the water until it boils. Then, the steam that’s let off from the boiling water is allowed to cool slightly until it turns into mist. Finally, the mist is distributed through the air, so the user breathes in warm mist instead of hot steam.
On the other hand, a steam vaporizer simply releases steam without allowing it to cool beforehand.
Are Warm-Mist or Cool-Mist Humidifiers Better for Asthma?
Ultimately for asthma sufferers, the goal is to increase the relative humidity in the air around them and break up the mucus that contributes to their inability to breathe properly. Some asthma sufferers find warm mist to have a suffocating effect on their airways; however, this is not the case for every person who has asthma. The decision to use cool mist or warm mist comes down to personal preference.
Warm mist often feels soothing during cold-weather months. Either route you choose, it’s crucial to keep the humidifier clean and to maintain a healthy humidity level because a high relative humidity allows dust mites to thrive, which can trigger asthma symptoms.
Therefore, you should look for a cool-mist or warm-mist model that has a hygrometer or humidistat, so you can keep the humidity level within the 40 percent to 50 percent range.
Why Is It Important for Asthma Sufferers to Keep Their Humidifier Clean?
For people who have asthma, bacteria and viruses may cause illnesses that can exacerbate their symptoms. Even the presence of mold can cause an asthma attack.
A dirty humidifier can create the perfect conditions for bacteria, mold and viruses to grow and thrive, which can quickly to a life-threatening situation for those whose asthma is severe.
What Is the Proper Way to Clean a Humidifier?
While exact care and maintenance instructions vary from model to model, there are a few maintenance tips that apply to all humidifiers. For asthma sufferers, keeping their humidifier clean is crucial to maintaining good health.
Change the Water
Old water acts as an incubator for bacteria. Even if you have a humidifier with a large water capacity, you should still change the water every day. By doing so, you can stop the growth of bacteria before it starts.
Use the Right Water
Although it’s unnecessary for people who don’t have asthma, those who do should avoiding filling the tank with tap water. Instead, opt for distilled or purified water, both of which contain a lower level of minerals. When you use tap water in certain humidifiers that don’t contain a filter, the humidifier may distribute these minerals into the air, causing you to inhale them.
Wash the Tank
After a while, hard water deposits can form on the inside of the tank. Since you don’t want any impurities to contaminate the humidifier’s water supply, you should wash the interior of the reservoir with mild soap and water, allowing it to dry before you refill it.
If the tank’s inlet is too small for you to fit your hand inside, run diluted white vinegar through the appliance for about 15 minutes. Then, empty the tank, let it dry and refill it.
Maintaining the Filter
If your humidifier has a filter, you want to make sure it stays clean. With models that have a reusable filter, rinse or wash it per the manufacturer’s instructions. If the filter cannot be reused, replace it as soon as it looks dirty.
The user manual that comes with the humidifier should give you a time frame of how long the filter will last. Never run a humidifier with a dirty filter because the filter will contaminant the mist.
What Are All the Features to Consider on a Humidifier?
Whether ultrasonic, evaporative or warming, the humidifier you choose should be a high-quality one. Also, it should have all the features you need to stay comfortable while managing your asthma symptoms.
Some features you can live without; however, others are indispensable when you have a chronic respiratory condition. From integral aspects like the correct room capacity to convenience functions such as night mode, there are many features to take into account when buying a humidifier.
Size and Capacity
Above all else, you must think about the square feet of the room where you intend to keep the humidifier. Is the room small or spacious? Typically, the manufacturer will provide this information in the product description.
However, you can also use the tank’s water capacity as a guide. The bigger the tank, the more moisture it can deliver.
The nozzle is the exit point for the mist in an ultrasonic humidifier, so it needs to work effectively. It should direct the mist straight or diagonally into the air with a lot of force behind it, so the mist can travel far and fast.
There are some humidifiers with a dual-outlet nozzle, which simultaneously releases mist in two directions. In an evaporative humidifier, the fan should have sufficient speed, and the outlet grill needs to be wide for maximum output.
Evaporative humidifiers don’t come with a filter because the wick itself does double duty, and it can eliminate bacteria if it’s an antimicrobial type of wick. Warm-mist-only humidifiers usually don’t have a filter since the heat they produce kills germs.
If you choose a cool-mist ultrasonic humidifier, the addition of a filter is crucial in keeping asthma triggers like mold and viruses at bay.
However, an ultrasonic humidifier without a filter should not be automatically ruled out of your search if it has a UV-C light. This specific ultraviolet light spectrum destroys bacteria, viruses and mold from the inside out. Therefore, it can keep the humidifier’s water supply clean. In turn, you won’t put yourself at risk of an asthma attack.
Hygrometer-equipped humidifiers offer precision control over a room’s relative humidity. Since this air moisture ratio plays a huge role in causing or preventing asthma symptoms, you can’t afford to under or over-moisturize the air.
In auto mode, the humidifier will maintain a healthy relative humidity until the tank is empty. If the humidifier also has a timer, you can let it run only while you’re asleep or exercising.
Aromatherapy and Liquid Inhalants
Depending on your particular triggers, you may benefit from aromatherapy. Some humidifiers contain a designated tray for essential oil use while others have an oil-compatible reservoir. Either way, you should pick essential oils that help relieve asthma symptoms.
Lavender oil can reduce swelling, decreasing bronchospasms. Eucalyptus oil and tea tree oil not only reduce inflammation but also loosen mucus buildup. Clove oil, chamomile oil and thyme oil are also excellent choices for asthma sufferers.
If you need to ease a nagging cough, there are warm-mist humidifiers that release liquid inhalant vapors into the air.
Asthma is a lifelong condition. Therefore, you need long-term protection for the investment you’re making in your health. This is exactly what a warranty offers.
If the humidifier breaks or malfunctions, you can count on the manufacturer to fix or replace it as long as it’s within the warranty period. The standard warranty period for a humidifier is 1 year; however, some humidifiers provide a warranty that lasts as long as 3 years.
The non-profit Asthma and Allergy Foundation of America conducts research and advocates for the asthma-and-allergy community. One of the ways this organization assists asthma suffers is through their joint partnership with Allergy Standards Limited.
Together, these two groups oversee the Asthma & Allergy Certification Program, which officially certifies products that meet their high standards for asthma and allergy care. If a humidifier has this certification, you can feel assured that it’s a high-quality humidification appliance.
Almost every humidifier gives you a general idea of how much water is inside of the tank. Tanks may be transparent or have a long viewing window. The ability to view the water level is not the only aspect to consider on a humidifier’s reservoir.
You should also look at how it’s designed. Does it separate from the humidifier or is it integrated? A removable tank is easier to clean; however, a built-in tank is easier to refill. Some models even display an indicator light or make a noise when the tank is empty.
When you don’t feel well, you need to relax in peace and quiet. A humidifier with a night mode function helps you get restful sleep. This mode will dim or turn off all indicator lights and the display screen’s backlight if it has one. Plus, it sets the fan or mist speed to its lowest setting to dampen the noise output as much as possible.
The type of controls is strictly a matter of preference. If you like the simplicity of streamlined appliances, you may want to opt for a humidifier with a simple turn dial that controls the power and mist-output rate.
On the other hand, if you want to have more operating functions at your disposal, a push-button or touch-button control system is a better choice.
