Difference Between Vaporizer and Humidifier

Vaporizer and humidifier Can solve the overly dry air in your home. Dry air can aggravate allergies, cause dry and dehydrated skin, cause sore throats or stuffy noses, and even give some people headaches or nosebleeds. Dry air also affects our immune system because if our nasal passages and lungs are not lubricated, they cannot properly trap bacteria.

We all need a certain amount of humidity to feel comfortable and stay healthy. This article discusses the key differences between vaporizers and humidifiers, and how to choose the right one for your needs.

how they work

Evaporators and humidifiers have different methods of adding water to the air:

  • The evaporator boils the water and releases it into the air as steam.
  • Humidifiers use ultrasonic parts to diffuse water into the mist, or use a fan to create the mist.

So while both vaporizers and humidifiers add moisture to the air, they use different methods to do this.


  • Rehydration with steam

  • Steam contains less contaminants

  • The steam can be hot enough to burn the skin

  • May leave mineral deposits, which can lead to bacterial build-up


  • Moisturize with a cool mist or spray

  • Option to heat the mist before releasing it into the air

  • Cold or warm fog does not cause burns

  • unlikely to have mineral deposits

how they can help

Both humidifiers and vaporizers can make your home more comfortable by relieving excess mucus, dry skin, chapped lips, and sore throats. They may be helpful for people with allergies.

Humidifiers and vaporizers can be especially helpful when someone has a cold to relieve symptoms, although they can be used when moisture is needed.

Watch out for excess moisture

You have to be careful with excess moisture in the humidifier or evaporator. If the room becomes too humid, it can promote the growth of mold and bacteria. A good rule of thumb is that if the humidity in the room is 30% or less, adding moisture will help. If the humidity exceeds about 60%, it may promote the growth of pathogens, mold or mildew.

Devices such as hygrometers can measure humidity, or your humidifier or evaporator may be able to be set at a certain level.


Air with sufficient humidity can soothe irritated nasal and throat passages. This may help relieve allergy symptoms.

If you have indoor allergies, if the relative humidity in your home is below 30%, and you have symptoms like chapped lips, dry skin, or irritated sinus passages, you may want to consider using a humidifier. Be aware, however, that high humidity can increase dust mites, mold, and other allergens, so it’s best to check with your healthcare provider before buying a humidifier.

People with allergies should thoroughly clean their equipment daily and use distilled water to help protect against allergens.


Babies have sensitive skin and delicate nasal and throat passages, so adding humidity to a dry room can be soothing.

For a baby room, a humidifier is a safer option so you don’t burn your baby with the vapor from the vaporizer. Make sure to clean the equipment thoroughly every day and monitor the humidity level.

Coronavirus disease

There is evidence that coronaviruses multiply in dry air, so adding moisture to the air can reduce the number of virus particles. In general, airborne viruses tend to die in more humid air.

Still following all COVID-19 safety guidelines

While they can help, you shouldn’t rely on vaporizers or humidifiers to eliminate potential COVID-19 exposure in your home. Be sure to follow all safety regulations. Air purifiers may have some benefits in removing coronavirus particles from the air, but the filtration available in home systems may not be enough to remove them completely.


if you have asthmaa humidifier or vaporizer might not be a good idea. However, if dry air bothers you and you want to use it, take extra care to clean it so nothing in the air can trigger flares.

Keep an eye on the humidity level so it doesn’t get too wet, which can promote the growth of mold and bacteria. This is not good for asthma patients.

dry skin

If you have chapped lips and dry skin, a vaporizer or humidifier can help relieve symptoms.

Keep the equipment clean and don’t let the air get too humid. If you still need more hydration, drink plenty of water to stay hydrated and use moisturizing products that are appropriate for your skin type.

How to Clean Your Vaporizer or Humidifier

Machines may vary, so follow the manufacturer’s instructions. Using distilled water helps prevent mineral buildup, which is a breeding ground for mold, mildew, and bacteria.

Follow these general steps to clean your humidifier or evaporator:

  1. Wash the water container with a mixture of water and a mildly acidic cleaner such as white vinegar.
  2. Let it sit for a few minutes, then rinse off.
  3. Use a soft toothbrush or cloth to wipe or clean buildup on other parts of the machine, but be sure not to submerge any electrical parts in water.
  4. You may want to sanitize the machine with a diluted bleach or hydrogen peroxide solution, but ultimately it’s best to follow the instructions that came with the machine, as these chemicals can damage the plastic or seals, causing the unit to leak or malfunction.


Vaporizers tend to be less expensive than humidifiers, but both have a great range. You can pay anywhere from about $15 to over $700 for a room humidifier. Vaporizers range in price from about $20 to $200.

Measure the room you want to humidify and check the capacity of the machine. Find out what features you need or want. Some machines come with a remote control, sleep mode to turn off the lights, a timer and a humidity set point. The type of features you want will likely determine the price of the machine.


Cleaning is essential when you use a humidifier or vaporizer. If you don’t keep it clean, you risk putting more things into the air than moisture, including pathogens and allergens.

Vaporizers are not recommended for infants or children, as the steam may burn them.

Always make sure the device is unplugged before cleaning.

Humidifier & Evaporator Takeaway

Humidifiers and vaporizers can make dry homes more comfortable and healthier, especially during cold winter months. They require regular but relaxing care. Before you choose, consider allergy concerns, safety, and the required capacity for the area you want to humidify.


Both humidifiers and evaporators add moisture to the air. The difference is that a humidifier uses a cool or warm mist, while an evaporator boils the water and releases steam. These machines make you feel more comfortable and relieve irritation from nose, throat, chapped lips and dry skin. It is important not to over-humidify and keep the machine clean.

VigorTip words

Humidifiers and evaporators are simple and effective at adding moisture to the air. If you want to add humidity to your house, list the features you want and the ones that are safest and best for your needs. If you have asthma or allergies, please consult your healthcare provider before using a humidifier or vaporizer, as it is not recommended for everyone. The possible disadvantages may outweigh the advantages.

Frequently Asked Questions

  • Where do you put your humidifier?

    Don’t put it too close to you or near your bedside. Put it on a shelf or on the floor a few feet away from where you’re going. Make sure it’s not too close to any objects, furniture or floors that could be damaged by moisture.

  • How close should you place the humidifier to the baby?

    The humidifier should be far enough away so that if it falls or babies reach for it, they don’t injure themselves with the scalding water. At least 6 feet away is a good guideline, but consider your child’s activity and make sure it’s not within grasping distance.
