Suffering from humid air coming in from your crawl space? Fix it today with these dehumidifiers - and avoid that humid headache for good.Read More
Anyone that has asthma themselves, or knows a person living with asthma, understands that humidity can exacerbate the condition.
In hot weather, air conditioners can zap the overall moisture in a home and leave you feeling wheezy and dry. In the winter, central heating can do the same for the humidity levels in your home.
A humidifier can help get your home’s humidity levels up to a comfortable level that is best for your health.
Check out our detailed reviews of the best humidifiers for asthma below.
Best Humidifiers for Asthma & Wheezing
The TaoTronics TT-AH025 Cool Mist Humidifier has a lot going for it.
The extra-large tank has a whopping six liters of storage, so depending on your settings, this machine can run for up to sixty continuous hours.
The mist stream can go up to one meter in the air, so there is little worry of damp patches on the floor, especially when put on a low setting.
This humidifier is great for kids’ rooms and hallways as it has a warm glow nightlight at the base of the unit that can be used in isolation from the humifying function.
A modern blue strip light along the side can also be turned on or off individually, depending on your preference. The wide opening makes filling and cleaning more straightforward, but we have found that it is best to run this humidifier until it is dry before refilling. If you don’t, then you’ll inevitably slosh water on the floor, so be prepared.
The TaoTronics TT-AH025 is also incredibly quiet compared to other humidifiers on the market.
|Includes a nightlight||Difficult to clean tank residue|
|All lights controllable (not stuck on at night)||Full tank a little tricky to place|
|Mists up to 60 hours in one fill|
|Mists up to 1 meter in the air|
It’s quiet as can be, sleek by design, and only has to be refilled every few days.
The fact that it sloshes water unless it is run completely empty works for our sense of laziness as well. Moreover, that minor issue wouldn’t at all dissuade us from buying this machine again, and the benefits easily merit its position as the best overall humidifier on our list.
The fact that TaoTronics has fantastic customer service is also why they will get our business again and again.
The MOVTIP Portable Mini Humidifier is the ideal size for travel.
At only just over five inches in height, this machine can easily pack into your carry-on suitcase and provide you with the comfort and benefits of a humidifier wherever you lay your head.
There is also a soft glow night light, which can be turned on or off separately from the humidifier.
One press of the button will begin the mist, and a second will change the mist mode to intermittent, whereas a third short press will turn the mist off completely. A longer button press will turn on the light, and a second long press will make the light fade in and out.
…though we don’t know why anyone would want that function.
Holding the button down for the third time will turn the light off.
Like us, you might be finding excuses for purchasing all of the colors on offer. Tucking one of these misters in by your houseplants will do wonders for keeping tropical plants in tip-top condition.
|Available in six color options||Can't add perfume or oils|
|Automatic shut off when water is low||Needs used with filters|
|Continuous or intermittent misting||Only works with USB|
|Soft night light|
We love it.
The MOVTIP Portable Mini Humidifier needs to be filled more often due to its small capacity, but running for 18 hours at a go between refills is fine by us. Filling it up is a breeze as well since it only uses 500 ml at a time.
The machine might be portable, but it will be used for way more than just traveling. This humidifier might make its way onto quite a few of our Christmas lists this year, especially at the price.
Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier
The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier is great for kids’ bedrooms as its whisper-quiet.
The nightlight is quite bright, so likely not conducive to being in adults’ bedrooms, but it can be turned on and off separately from the misting function.
You can rest assured that the machine is safe around little ones with the cool ultrasonic mist that doesn’t require any internal water boiling, and the mister can be directed for maximum efficiency.
Saying that, the machine is easily tipped over due to its narrow design and can be challenging to fill without spilling water.
The 1.5-liter water tank is great for bedrooms and smaller areas but will need to be refilled on a daily basis if being used continuously. Cleaning the Pure Enrichment MistAire is the main downfall of this unit, but if you are willing only to use distilled water, this issue should be negligible.
|Super quiet||Easy to tip over|
|Great nightlight design||Bottom of tank difficult to clean|
|Easy mist flow direction||On/off button is always lit up|
|With or without filters|
If you want a humidifier to be used occasionally for a kid’s bedroom when they are sick or during specific seasons, then for sure, this Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier is a great machine.
The nightlight is bright; the mist can be directed. It’s simple to use and easy to store. However, we would recommend keeping it out of reach of little ones unless you want knocks and spills, and you will regret it if you don’t stick to only using distilled water.
MistAire customer service is top-notch, though, and we are very impressed with their willingness and ability to rectify any issues that arise and answer questions.
GENIANI Top Fill Cool Mist Humidifier
We love it when a machine can do double duty so getting a humidifier that can also work as an essential oil diffuser is already one up on our list.
The GENIANI Top Fill Cool Mist Humidifier has a built-in essential oil tray to add your favorite soothing or invigorating scents and will make your home smell amazing.
Working as a humidifier, this machine has a large 1-gallon water tank, so it can be run continuously for up to 18 hours before needing a refill. There are four mister settings so you can alter the output to your preference, and when the water reservoir runs dry, the unit will automatically turn off. Unlike many humidifiers, this is easy to fill and to keep clean, which is a significant bonus.
It also doesn’t look especially like a humidifier, so it can blend in with your décor better than most. That being said, the mist doesn’t shoot up in the air very far, so it can make the area around the humidifier wet, especially on a higher setting.
|Super easy to fill||Nightlight isn't super bright|
|Very easy tank to clean||Can't control mist direction|
|Modern design - subtle|
Regardless of whether you intend to use the essential oil tray, this is a great humidifier.
The large tank is incredibly easy to fill without sloshing water everywhere, like many other humidifiers. The tank is straightforward to keep clean, which adds to the longevity of using this machine, which is especially vital to asthma and allergy sufferers.
The designers should get a pat on the back, as we would undoubtedly rebuy this humidifier, and you can’t get a better recommendation than that.
Everlasting Comfort Cool Mist Humidifier
If you are on the lookout for a humidifier that can output a lot of mist, then the Everlasting Comfort Cool Mist Humidifier is a winner.
The 1.5-gallon storage tank could run up to fifty hours on a very low setting, but due to the high-volume output, you will likely be refilling the unit twice daily if you intend to use it on the highest setting.
Refilling is relatively mess-free and is pretty easily done without splashing water; however, the tank is large and, therefore, heavy when filled. There is no handle, so it can be challenging to move from your sink to the central unit.
Not needing any filters is a significant bonus as finding replacement parts for a humidifier can become near impossible as the years go by.
The tray for adding essential oils is also welcomed for making your rooms smell lovely and assisting with destressing and getting a peaceful night of sleep.
|Super quiet||Black model shows fingerprints|
|No filters needed||Heavy, especially with a full tank|
|Essential oil tray|
|Rooms up to 500sq. ft.|
If you have a particularly dry house with very low humidity, then the Everlasting Comfort Cool Mist Humidifier might be the answer to your problems.
Sure, there is a sizeable 1.5-gallon water tank, but even more important is the serious amount of misting output that this machine is capable of handling.
Anyone that has looked into the exorbitant cost of adding a central humidifier system knows that adding a few Everlasting Comfort Cool Mist Humidifiers to their home will be a fraction of the price and serve the same purpose.
Buyer's Guide to Asthma Humidifiers
There are numerous humidifiers on the market, and all purport to be the very best. However, not every humidifier will be best for your specific needs. Below we have included a few key factors that you should look out for, so take the time to consider what aspects will be beneficial to your situation.
Humidifiers are available in cool mist, warm mist, and ultrasonic varieties. Each has its own pros and cons:
|Energy Efficiency||Safety||Noise Level||Aromatherapy||Asthma and Allergens||Use with hard water|
Auto Shut Off
To stop your humidifier from burning out, having an auto-shutoff button is a must. Unless you are a severe Type A personality and check your humidifier like clockwork, or are a robot, then you will inevitably forget to refill the machine in time.
The size of the water tank will determine how often you might need to refill it. You also want to check the coverage capacity to see how large of a room the humidifier is meant to cover. If you have an open-plan house, then you might well need to have a few humidifiers to increase the moisture levels to where you are more comfortable. The Everlasting Comfort Cool Mist Humidifier can up the humidity in a room up to 500 square feet.
Larger humidifiers have their benefits since you don’t need to refill them as often, but this also means that they are more challenging to move around in your home, especially if they have already been filled with water. Think about how often you intend to transfer your humidifier and then buy a unit that will be comfortable to move as needed. There are some great travel-sized humidifiers that can also be used to increase the humidity in specific areas of your home.
Check if the humidifier needs filters. Though these are a bonus as they can clean the air at the same time as misting, it will be an added expense and hassle always to have them in stock.
If the humidifier doesn’t come with an in-built humidistat, you might want to consider buying one separately. Just as living with low humidity can negatively impact your overall health, so can having the humidity levels too high. Some top of the range humidifiers will have a humidistat that automatically turns the machine on and off, depending on the humidity and settings.
Quite a few humidifiers double up as a nightlight, which is an excellent feature for hallways or children’s bedrooms. However, ensure that the light is of an appropriate brightness and can be turned on or off separately from the misting action. The Pure Enrichment MistAire Ultrasonic Cool Mist Humidifier has a bright nightlight that is perfect for hallways and kids bedrooms.
Ease of Cleaning
Buying a humidifier to improve your health will be counterproductive if your humidifier isn’t kept clean. Ensure that you can get to the water tank to clean it thoroughly so that you won’t be adding any bacteria or allergens to your living space. If we did an award for ease of cleaning, then it would undoubtedly go to the GENIANI Top Fill Cool Mist Humidifier.
If you are a fan of the smell of tea tree, lemon or menthol, then look for a humidifier that is specifically noted to handle essential oils. Warm mist humidifiers will do the trick but ensure that you pick a model where this feature is specified. Aromatherapy oils can aid with putting you to sleeping and keeping you in a deeper sleep and also ease depression and seasonal anxiety disorder.
Like anything consumer product, prices for humidifiers range from super cheap to crazy expensive. However, even more important than price is value. All of the humidifiers on our list have been tried and tested for longevity and usefulness, and none will set you back more than $100. The portable humidifier is so reasonably priced that we want one in every color. Some low-priced models may suit your needs just fine and can be easily moved from room to room in your house as needed.
Frequently Asked Questions
Can a humidifier help with asthma?
Sustaining the ideal humidity level in your home can be critical for people living with asthma. If the humidity is too low, asthma can become harder to control. Your respiratory system can become irritated and dry, resulting in an increased propensity to catching colds or other viruses. Conversely, high humidity levels in your home can enable allergens like mold, mildew, and dust mites to take over. A 30-50 percent humidity level indoors is comfortable for most people and can be ideal for those with asthma.
Indoor heating, cold weather, and dry climates can significantly lower the humidity in your home. Many people living with asthma have found that a humidifier can be helpful; however, this has yet to be widely accepted by the medical community.
Is a cool or warm mist humidifier best for asthma?
Both a cool and warm mist humidifier achieve the same function by putting moisture into the air and increasing the humidity level. Which is best for asthma really depends on your personal preference. Do you like being in a steam room? Do you feel your breathing improves after being in a steamy shower? In this case, then a warm mist humidifier might be your best option. If you don’t like being in a sauna or hot feel that you struggle to breathe in a hot, steamy room, then a cool-mist humidifier might make you feel more comfortable.
Warm mist humidifiers heat the water in the machine to create steam, but then cool it to cool it slightly for safety to expel a warm mist. On the other hand, some cool mist humidifiers have a fan system that dispenses a cold mist into the air. In contrast, others vibrate the water with ultrasonic frequencies to produce smaller molecules. The latter type is generally much more expensive.
Other health benefits of humidifiers
Humidifiers can be helpful to your health for more than just your respiratory system. By increasing the overall humidity in your home, humidifiers can assist with relieving the symptoms of:
- Hoarse throat
- Dry throat
- Dry nose and nasal passages
- Chronic bloody noses
- Dry cough
- Dry, cracked lips
- Dry, irritated eyes
- Dry skin and eczema
Humidity levels can affect your health in more ways than just your breathing.
Lower air moisture can trigger allergic reactions that can exacerbate asthma symptoms and a myriad of other health concerns. Upping the humidity in your home can help you get a good night of sleep and feel better overall. The TaoTronics TT-AH025 Cool Mist Bedroom Humidifier gets a pat on the back for being our overall winner for best humidifier.
However, check out all of the machines on our list as some are better suited for travel or for homes with a very low overall humidity.
