Difference between Humidifier and Air Purifier

We can all agree that numerous people across the globe use air purifiers at home. However, people are also using humidifiers. You can also find people that are using both of them as well.

The main problem is to understand what is the main difference between these products so that you can determine which one is the best for you.

In this particular guide, we decided to present you with a comprehensive guide that will help you understand everything about these two machines.

Have in mind that both humidifier and air purifier will help you improve indoor air in the long run. However, it may be challenging to determine which option is the best for your particular requirements.

For instance, both products are great for people with respiratory issues and sinus conditions, but the way they provide the relief is entirely different. An air purifier tends to cycle the room’s air by using a wide array of filters.

These filters will remove both contaminants and allergens so that you can improve the air you breathe inside your household. On the other hand, a humidifier can help you add the moisture into the room’s atmosphere.

Therefore, it is the best solution in case that air within your household is dry and you have respiratory and sinus issues due to it.

The Differences Between Humidifier and Air Purifier: Basic Functions

Even though most people think that both products are perfect for your particular household, that is not the case, and we decided to present you reasons why:

Air Purifier

Have in mind that the primary purpose of air purifier is to remove contaminants that you feature in indoor air so that you can improve your convenience and health.

It tends to trap bacteria, dust particles, mold spores, allergens, smoke odors, pet dander as well as other harmful particles that will help you along the way.

As soon as you run an air purifier, the air will enter the machine and through various filters based on the model that you decide to purchase. One of the best cleaners that you should get with this particular product is a HEPA filter that can capture tiniest particles.

The best thing about it is that you will get 99.9% efficiency when it comes to removing contaminants that cause respiratory conditions such as asthma and allergies.

You should remember that air purifier will not improve the moisture inside your household, but its main goal and function is to filter out the pollution and clean the air in general.


On the other hand, a primary humidifier’s function is to return the moisture inside the air in situations where you have issues with air dryness. It does it by placing water vapor inside the room, which is not visible in general.

If you wish to keep it running all the time, you have to place the water inside the reservoir. Therefore, it will use the water, convert it into the mist, and expel it into the surroundings.

Humidifiers are great solutions that you can use in dry areas because they will help you add the moisture inside the air so that you can avoid respiratory issues that will affect you.

Have in mind that humidifiers are great because they will help you relieve dry skin, sinus issues, throat irritation, breathing problems as well as nosebleeds that you may experience in a dry climate.

It is essential to understand that humidifier can raise relative humidity levels, which means that if you already have moisture inside your household that could cause severe issues such as mold growth.

The main idea is to maintain indoor humidity between 30% and 50%. In case that the value is below 30%, it is considered dry, and it may cause issues that we have mentioned above.

On the other hand, if you have more than 50% humidity, that could encourage dust mite reproduction, mold growth, and mildew.
