Humidifier and air purifier: do humidifier help with dust or air purifier is the only option? 

Due to the huge number of scientific discoveries related to the impact of air quality on humans and the environment, the world has invented a bunch of devices that will help you improve the quality of life, health, and cleanliness of your home through direct contact with home’s air, for example, dry air humidification or cleaning from dust mites.

In this bet, we will analyze two main devices for dealing with damaged indoor air, air purifiers, we will study their differences, what types of these devices and under what circumstances you need to buy, and of course, the main question is which of these two devices really help with dust dirt and will even help to prevent dust mites grow.

What is a humidifier?

Firstly, we need to get clear with the main term, such as a humidifier. A humidifier is a device that is used to increase indoor humidity levels. Their structure and principle of operation completely depend on the type of humidifier, since different types have different purposes, that is, different components.

Most often, when using a humidifier, you will notice some kind of “water vapor” that will significantly improve air quality if you have a climate problem and constantly dry air, or if your room is built in such a way that you constantly feel dry indoor air.

Does it help to get rid of dust particles?

On the one hand, of course, humidifiers have their advantage in the destruction and control dust since particles of dust absorb moisture and stop flying through the air, sticking to surfaces. From what exactly is in the air itself, the amount of dust is noticeably reduced.

However, does this help prevent dust mites or does it clean up pet dander already? No, because even though moisture causes dust to settle in one place, without cleaning, this is not at all a favorable process for your home.

What is an air purifier?

Now, we should get closer to the term air purifier. Air purifiers are devices whose key task is to purify the air, through special filters, and rid it of harmful microparticles.

The basic principle of air purifiers is the ability to clean the indoor air through special filters, which differ from each other depending on the functionality. For example, HEPA filtration removes dust and even pet dander, but carbon filtration is set up specifically to remove toxins when air passes.

What are the differences between a humidifier and an air purifier?

And since many people might have questions: what is the difference between these air purifiers and humidifiers, we have prepared a list of differences that will help you understand why both an air purifier and a humidifier can be both a helper and a pest.


Of course, the main difference is their principle of operation, the structure, and the functionality of working with indoor and outdoor air.


The humidifier is used specifically to increase the humidity in a room from 20 percent dry air to 50 percent improved indoor air quality. This can lead to cleansing, but this is not the main task of the device.  

The principle of operation of this device is very similar to a kettle, as the water inside the device heats up and releases steam, which, when mixed with air, increases the amount of moisture and allows humidifiers to add moisture to the “atmosphere”.

Air purifier:

An air purifier is configured specifically to purify the air, namely the destruction of any polluting particles, such as dust or dust mite populations. The principle of operation differs from humidifiers even by the very structure of the device.  

Air purifiers have some sort of compartments, as in an air conditioner for dirty air and clean air, the air enters the device, and passes through the filter, after which the already purified air goes through the clean zone.

Influence on health 

You should also understand that air purifiers or humidifiers will directly affect your breathing. That is why we will analyze what are the main differences between these two devices for your health, such as nasal passages or soothe dry sinus passages.


A humidifier is a good thing for your health in many ways. In particular, in winter. For example, if you have a predisposition to dryness, due to which dry skin or chapped lips appear in low humidity, and creams with hygienic lipsticks do not help at all, then the humidifier solved this problem by creating a favorable climate.

However, a humidifier is also not a very healthy device. An increased amount of moisture can trigger allergies, for example, if you have a respiratory system that is sensitive to humidity.

Air purifier:

In the case of the purifier, it is safe to say that this device is safe for your health and respiratory system. First, purifiers don’t add anything to the air you breathe, they only take any pollutants out of it. Moreover, they cannot provoke any other allergens reactions, since, on the contrary, they eliminate the main airborne allergens triggers of inflammation.

However, on the other hand, air purifiers will not help you with dry skin in any way, unlike humidifiers, as they do not add any useful components to the air.

Even though it seems that the price tag of these two devices is the same, this is not the case because, firstly, the structure itself is different, and secondly, the popularity and convenience of the product itself also matter.


The price of humidifiers most often does not exceed $200. This can be attributed to the simplicity of the mechanism inside because the water simply heats up, creating steam. This is a rather economical option, especially if you have a small enough room and only need one humidifier.

Air purifier:

Air purifiers are already becoming a product that will cost an order of magnitude higher. However, the exact price cannot be said, as companies range from $100 to $1000, it all depends on the type of purifier and of course the manufacturer. The type of filter is the main thing, as you need to understand how professionally it must be made to absorb even the smallest particles of dirt.

For example, a purifier with a regular filter may be ok for the price and even be able to remove large clumps of dust, but it will be useless for toxic cleaning.

Time of effective work

And in the end, it is worth noting for which situations and times it is best to use a cleaner and humidifier. This will help you understand whether it is worth spending money now or it is better to wait, and perhaps, on the contrary, the device should appear without any slowdowns:


A humidifier is best used in winter, as that is when humidity levels are the lowest and dry air appears. However, if you feel that your room is very dry, and it is summer, spring, or autumn, do not limit yourself, as moisture in the room should be present regardless of the temperature outside.

The humidifier needs to be monitored and not left constantly, it is best to buy a humidifier that will calculate the percentage of moisture in the air and stop when it reaches the norm.

Air purifier:

The air purifier can be used all year round. That is, air purifiers will always be needed, even if it seems to you that the air is especially polluted at a certain period, it is better to use an indoor air purifier on an ongoing basis in order not to allow any dirt or toxins to enter your lungs. It is best to stop using the cleaner occasionally and only when necessary.

Is a humidifier or air purifier better for dust?

Objectively, an air purifier does a better job of dealing with dust than a humidifier, at least because the main function of the filter in purifiers is to remove small particles from the air. For cleaning dust, it is better to choose a cleaner.

Moisture from the humidifier can lead to mold spores, which can make the field worse. While the indoor air purifier is completely harmless to the room.

What are the types of humidifiers?

Below you can find a list of types of humidifiers, which differ in general in terms of humidity levels and in the way they deal with dry air.

1. Warm mist

Mostly it’s normal steam with mid-indoor humidity levels that you can see, and you can even feel because of the temperature.

2. Cool mist

Most often, minerals are added to such humidifiers, they have a low humidity temperature. Cool mist with low humidity levels will be hard to feel or see.

3. Ultrasonic

With the help of ultrasonic clarity of water ejection, you will only observe a light mist dissipating in the air.

What are the types of air purifiers?

We have also compiled for you a list of types of cleaners, which mainly differ in filter and cleaning of polluted air method.

1. HEPA filters

These air purifiers are set up specifically for the usual cleaning of tiny particles of pollution in the air, for example, airborne dust particles or pet dander, well suited to prevent dust mites.

2. Carbon filters 

These air purifiers do not work with hard small particles, but with toxic indoor air pollutants. Carbon air purifiers also help fight bad odors.

3. Negative ionization air purifier

This air purifier captures particles in the air with charged ions, weighs them down, and thus makes them pass through the filter with ease.

4. UV

This air purifier uses special ultraviolet light to destroy bacterial indoor air pollutants. UV Air purifier destroy the very structure of bacterial DNA.

What helps with dust in the air?

The best way to get rid of dust and its effects, such as dust mites, is regular cleaning. Although the purifier can remove some of the dust from the air, it is worth paying attention to the cause of a large accumulation of dust. Also, a good assistant, except for air purifiers, in the fight against dust in the air is a vacuum cleaner.

Can a humidifier make your house dusty?

In fact, and surprisingly yes, since the moisture from the humidifier can influence and increase the amount of mineralized dust and subsequently dust mites. You must understand that humidifiers, unlike air purifiers, are not purifying devices.  

Yes, in some cases, humidifiers help with dust and dust mite populations, but this help is no more effective than regular cleaning. In addition, mold spores can be more devastating for indoor air quality. Mold spores just appear in the room from too much humidity in the air.


Both the air purifier and humidifier are great devices that will make your life easier, and improve your health and even your mood, as you will feel like you can breathe deeply in a clean room with clean indoor air. 

However, after reading this article, you understand that for the effectiveness of these devices, you need to clearly understand their principle of operation. For example, do not use a humidifier against dust mites or a purifier against dry air, as you will get nothing but negative consequences.

We hope this article has helped you figure out if you really should use a humidifier to help with dust control, and if you should get a purifier as your main dust control device.
