A Quick overview of Humidifier vs Purifier

Humidifier function

Is an air purifier the same as a humidifier

Humidifiers are designed to increase the relative humidity (RH) level in a room or building space. They usually operate by passing water through a heating element and then circulating it back into the room.

Air Purifier function

Difference between humidifier and purifier

An air purifier eliminates pollutants from the air, such as pollen, smoke, dander, mold spores and dust mites. An air purifier uses filters and other technologies to remove these substances from the air.

In all we said so far about humidifiers and air purifiers, that is not all. Read on to find in detail the complete difference.

Differences between Air purifiers and Humidifiers

  • Air purifiers use filters, while humidifiers don’t. The filters include a HEPA filter, Activated Carbon filters and pre-filters to capture airborne particles.
  • Humidifiers use evaporative hot mist or ultrasonic waves to create a cool mist to help moisture the atmosphere.
  • Air purifiers can clean the air, while humidifiers can moisture the air. They can not be interchanged.
  • A humidifier is designed for those suffering from air dryness, tiredness, headache and sinus, while a purifier is mainly designed for those experiencing polluted air and allergies. To get rid of smoke and bad odors.
  • Air purifiers can be used in a home or office to cleanse the air from cigarette smoking and bad odors, but humidifiers can not purify the air.
  • An air purifier is suitable when we have low indoor air quality. On the other hand, a humidifier is a better option when we have low indoor humidity levels.
  • Air purifiers can be used at all times, but a humidifier is suitable for winter days.

With no long debate, you can see that there is such a huge difference between the humidifier and purifier. But even at that, both devices still share something great in common. What that’s the similarities?

Similarities between Humidifiers and Air purifiers

  • Both humidifiers and air purifiers can serve Asthma allergy sufferers.
  • They can be used together in the same room. So you have no issues at all getting them both for yourself or your loved ones.

Note: Please avoid using humidifiers for allergies purposes as it could worsen the issue according to our findings.

Having indicated the core difference between a purifier and a humidifier, let’s take a quick recap of whom the two devices can serve and their functions.

Having gone through a brief functionality of an air purifier, plus including what a humidifier can do, let’s have a detailed view of what they are up to. So Can they help with Asthma? What about COVID, Sinus, and Eczema? Should we also use it for a baby? Let’s see how it goes with Humidifiers and Air Purifiers.

Air purifier or humidifier for asthma

If you or any close one is suffering from Asthmatetic symptoms, it will be fair enough to want to consider which of these units works better for asthma.

Because humidity and indoor air quality matter and play a very big role. According to our findings, it’s seen that Humidifiers are used to increase humidity levels in the air that we breathe. This can help reduce symptoms associated with asthma but Air purifiers remove pollutants from the air. They may be used to treat asthma.

In this, we can say both are good, but air purifiers can better help with Asthma. Humidifiers are used to increase moisture content in the air. This helps to reduce dryness in the lungs and reduces the risk of developing asthma. They can be used in both indoor and outdoor environments.

An air purifier removes dust particles from the air. These particles can cause respiratory problems if inhaled. An air purifier should be placed near your bed at night to remove any allergens that may trigger asthma attacks. In this case, we recommend opting for an air purifier because it does the task better.

Air purifier vs humidifier for COVID

The best air purifier for coronavirus is an electrostatic precipitator (ESP). This type of filter uses electrical charges to remove particles from the air. They are effective at removing viruses, bacteria, pollen, dust, smoke, odors, and other pollutants. ESPs use a negative charge to attract airborne contaminants while allowing clean air through.

A humidifier can help reduce the spread of coronavirus by increasing humidity levels in your home. A humidifier works by adding moisture to the air, which helps prevent the formation of droplets that contain the virus. It can also help prevent colds and flu by increasing the amount of moisture in the air.

Air purifier vs humidifier for sinus

Sinusitis is inflammation of your sinuses. This happens when bacteria or viruses enter your nose and cause swelling and irritation. If left untreated, this condition can lead to chronic sinus infections.

You may have heard that using a humidifier helps prevent sinus infections. However, recent studies show that humidifying your home environment increases the risk of developing sinusitis. Some researchers believe that humidity levels in homes should be kept below 50%.

In contrast, air purifiers do not increase the risk of sinusitis. Instead, they help keep your sinuses healthy by removing dust, pollen, mould spores, pet dander, smoke, and other allergens from the air.

So if you suffer from sinus problems, consider investing in an air purifier instead of a humidifier. However, they don’t do much for your sinuses. If you’re looking for something that will help clear up your sinuses, consider using a steam vaporizer instead.

Air purifier vs humidifier for eczema

Air Purifiers are great at removing allergens from your home but they can cause problems if you have asthma or other respiratory issues. Humidifiers are good at keeping your air moist and making it easier to breathe. They are not as effective at removing allergens but they do help keep your air clean. Also When you have an air purifier running, it creates negative ions that irritate the skin and cause the immune system to react. This makes the symptoms worse. If you do decide to get an air purifier, look for one that has HEPA filters.

Still, we recommend that If you suffer from eczema then you should invest in some sort of humidifier because it adds sture back into the air, which helps loosen mucus and reduce inflammation. Coupled with the fact they keep the skin hydrated. Thus control eczema.

Air purifier vs humidifier for baby

Babies need clean air, and good breathing enabled environment. As you can see, an air purifier purifies the air to make it clean and infection-free, while humidifiers moisture the air to make it humid and dry free. In this case, we can’t be specific on which one is better as both perform what is needed for babies and newborns. It all matters what your baby is lacking.

If your baby needs cleaner air, it’s fine if you choose a good purifier for your baby, but if it’s a mositured environment that your newborn needs, then opt for the humidifier. However, we do recommend you get both the humidifier and purifier to help fix both problems as your baby needs both to stay healthy and strong.

Note: You can run both air purifiers and humidifiers at the same time.

Types of Air Purifiers

Purifiers are a great tool, but not all air purifiers are created equal. There are two types of air purifiers: the HEPA filters and Ionizers;

  • HEPA filters: These are the best type of air purifiers. They have high-efficiency particulate arrestance (HEPA) filters. This means they trap 99.97% of airborne particles 0.3 microns or larger.
  • Ionizers: These are less effective than HEPA filters but still good enough to keep your home clean.

Ionizers work by creating negative ions in the air. Negative ions are molecules with a net charge of the same polarity as positive ions. Positive ions are created naturally by sunlight and other sources. Negative ions are created artificially through ionization. So if you want to breathe better, get a quality air purifier.

Types of Humidifiers

Two types of humidifiers can be used, Let’s take a look at each of them:

  • Evaporative humidifiers use water vapor to create humidity. This method works best if you have a large space and don’t need to control the temperature of the growing area. Evaporative humidifiers work well for indoor grows but they do not produce enough moisture for outdoor grows.
  • Air-jet humidifiers use compressed air to atomize water into a fine mist. Air jets are the most popular choice for growers who want to maximize their space. They are easy to clean and maintain. However, they only produce a small amount of moisture. They are great for small spaces like closets and bathrooms
  • Ultrasonic humidifiers use sound waves to break down water molecules into smaller particles. These particles then fall back to the surface where they re-evaporate into the air. They are expensive, difficult to install, and need frequent cleaning.


Both air purifiers and humidifiers are beneficial tools to help maintain a healthy indoor environment. Choose the right device for your needs, and enjoy a healthier home! If you need a device to control humidity temperature, a humidifier sounds like such a great option. But in the case where you want to purify the air to make it free of allergies, the Air purifier does better. Regardless, both the humidifier and purifier can be used together.
