Best Humidifier for Asthma

If you are currently suffering from asthma or know someone close to you who does, you should be all familiar with how important it is to maintain optimal humidity levels. Environments that diverge away from the ideal tend to be very uncomfortable – verging on dangerous at the worst of times – for asthmatic individuals who will begin to face difficulty breathing amongst other symptoms.

Humidity to the asthmatic is truly an enemy. It can not only cause breathlessness and pain to breathe but can affect their entire life – from causing restless nights of poor sleep to irritability throughout the day.

The solution to this is actually quite straightforward: get a good humidifier. While they obviously aren’t the be-all-end-all cure to asthma, they can do a heck of a lot to reduce the burden of the condition. So, if you think you’re in need of a good humidifier because of your asthma or know someone who does, we invite you to check out our reviews below of some of the best humidifiers for asthma.

A Buyer’s Guide


A good humidifier is one that goes completely unnoticed yet manages to affect your life positively. One way humidifiers often get in the way of going about with daily life (or even sleep for that matter) is when they become too noisy. Depending on you, you might either find yourself annoyed at the constant hum of your device or might even find it comforting.

Decide for yourself on how much background noise you’re able to tolerate during work and sleep before settling on a product – not all humidifiers are built equally in this regard! 


While cleaning is easy, one thing we’ve noticed that affects everyone is laziness. Don’t be lazy when it comes to cleaning your device – both your wallet and lungs will thank us in the long run. Without proper cleaning and maintenance, your humidifier won’t be able to function optimally which is a waste considering how easy it is to clean.

Simply pop open the lid and apply some fresh water along with vinegar and give it a good scrub (unplugged) for a minute or two, followed by a rinse and you’re all done. 

Essential Oils

Essential oils are totally optional but depending on your asthmatic status, such aromatherapy may or may not be beneficial for you. Essential oils may produce great aromas which all will appreciate but make sure you check with your personal doctor first on whether it is safe for you to use them.

You don’t want to trigger your asthmatic attacks unwittingly after all.


Frequently Asked Questions (FAQs):

Is there anything I should know before using a humidifier if I suffer from asthma?

We strongly believe that you should consult your doctor before making any drastic changes to your daily routine, especially if you’ve never used a humidifier before. While they have a great many benefits for the asthmatic, if humidifiers run at overly high levels, they can aggravate existing conditions.

Further, the tap water you use may contain unhealthy minerals that can impact your lungs. To minimize the risk of this, we suggest using humidifiers with filters if this applies to you along with washing it without any chemicals (just use vinegar).

If I have young children or pets at home, can I still use my humidifier?

There should be absolutely no issue with this at all. Humidifiers are incredibly safe products so long as you do not have any preexisting medical conditions. They after all are just evaporating clean water into the surrounding air!

The only risk comes with how it contains hot water so to counteract this problem, if you have kids or pets running about make sure to keep your humidifier somewhere far out of their reach like on a bookshelf or on top of a cupboard.
