The Difference Between Diffusers and Humidifiers

Aromatherapy and the use of essential oils can bring joy, relaxation and contentment into your life with all their benefits. Sometimes people wonder how to achieve the best results, they wonder which is best to purchase. Should it be a humidifier or a diffuser? Combining the two will also give you excellent results.


Diffusers come in different shapes and sizes and you should not confuse the humidifier with a diffuser. You get four essential oil diffuser types.

They are:

  • Nebulizer
  • Ultrasonic
  • Evaporative
  • Heat

Diffusers have been designed so that a fine mist is vaporized by using the essential oils for a cold effect in aromatizing your room.

The diffuser does have great advantages like enhancing your mood with changing the scent of a room or house.

It also purifies the air that you breathe. The scented oils can be absorbed into your skin leaving you relaxed and soothed.

A diffuser is often used to reduce bacteria and fungus that is in the room.

Diffusers can be costly, especially the better ones .. sometimes it is better to spend a little more in the beginning as in the long run it will save you money.

There are some models that come with a light which is often used as a nightlight in a nursery or child’s room.    If you don’t like the light in your bedroom you can usually turn the light feature off or not use it in the bedroom.

Some people don’t like the noise that some diffusers make. You can have a diffuser that works in both ways – a humidifier and a diffuser. Or you can buy them separately. 2017 trends are showing that people use a diffuser multi-purposefully, doing both the functions of a diffuser and a humidifier.



If you own a humidifier, you will notice that it maintains the level of moisture in your room. Dry climates particularly benefit from much needed moisture and in winter time. Skin dryness, viral and bacterial problems are triggered when there is such intense dryness in the air. People seek out humidifiers for themselves and their children for assistance with this dryness.   During winter when we have heaters going in the house it is often a good idea to add some moisture back into the atmosphere.

There are many humidifiers on the market place that do not support the use of essential oils. If you do want a humidifier for essential oils, perhaps your best bet would be to select a small diffuser that uses essential oils. This is known as an essential oils diffuser.

A humidifier has great advantages in that it will reduce the dryness in the air, replacing moisture. Sore throats, cough and dry skin are relieved. Those with allergies and asthma experience great relief and a humidifier is great news for family who have to put up with other people snoring.  Moisture from a humidifier will even keep your furniture and other things from drying out.  Just remember with a humidifier around, some units will boil water inside and this can cause danger to pets and small children.

The difference really lies between moisture or refreshment

Basically, the main difference between a humidifier and a diffuser is that the humidifier keeps the atmosphere in a room moist whilst a diffuser will freshen the air with essential oil droplets.

If you have newborn or very little children in the home, you are best off with a humidifier and that would be the right choice. The thing is, whilst the essential oil diffuser might well have therapeutic benefits for us adults, there are some essential oils that can cause health problems when not used properly. Children usually are the susceptible ones. Research done by the University of Minnesota reveals that there are some essential oils, for instance like peppermint that should not be used when there are children under the age of 6 in the home. There is a major chemical in peppermint oil, called Menthol-one, which can cause breathing problems in young children.

When it comes to humidifiers, parents who do research discover that there are certain humidifiers that suit the home even more when there are young children in it. A paediatrician generally will recommend that you do not use humidifiers that emit warm mist into the air with small children around. This is to protect them around boiling water and spillage. That means that the cool mist type humidifier, the ultrasonic humidifier is best when there is a baby in the home.


Bottom line

You might be a newbie when it comes to the choice of a diffuser or a humidifier in your search for improving your wellness. If you have a small child, start with a humidifier for improving the moisture content in your home.  Maybe just wait a little until baby is a bit older before you start discovering the wonders of diffusing the wonderful aromas of essential oils into your home.
