Best Mist Humidifiers Diffusers For Your Home

So you’ve decided that a simple humidifier does not meet your needs anymore. You want something more, something that will also freshen up the air in your room and create a nice, soothing effect.

In that case, a diffuser is the right device for you. It uses water in combination with essential oils, and sends the aromatic mist in the air. Some immediate effects of such device include: cough, cold and flu relief, reduced smell of cigarettes and tobacco, as well as eliminating pet odors.

How Do Mist Humidifiers Diffusers Work?

An aroma diffuser is a device that turns water into vapor or mist. The aroma or pleasant smell comes mainly from essential oils. These are mixed in the water and carried in the ambient via mist.

Most aroma diffusers are ultrasonic nebulizers. The ultrasonic diffusers work through a ceramic plate that emits ultrasounds (not perceptible either by humans or pets). These ultrasounds break the water molecules and transform them into a thin, perfumed mist that is pushed to the outside of the diffuser by a fan. This method also contributes to athoroughly humidification of the environment.

Types of Mist Humidifiers Diffusers

From the very beginning, you must know that such devices come in a variety of patterns and colors. You can choose one that will best suit the decor of your home. Also, the price of the diffuser varies, depending on the material from which it is made.

You can buy a humidifier diffuser made out of plastic, wood, ceramic glass or metal. The more valuable the material, the more costly the product.  Given that it is a good that is always on display, it is important to decide on an aesthetically pleasing model .

An even more important criterion to consider when buying a mist humidifier diffuser  is the type of aroma dispersion it provides. Different modes of operation guarantee different effects, so it is good to know all types of devices before making a purchase.

Best Device for Aromatherapy

Essential Oils Diffuser Humidifier Combo

The best way to use essential oils for safe, effective and affordable aromatherapy is to use a diffuser. These small appliances are specifically designed to properly disperse essential oils in the air.

The diffusers break down the essential oils into micro-particles that form a fresh, uniform and extremely fine mist. Unlike hot steam humidifiers that alter the properties of essential oils, diffusers use cold air and a nebulizer to preserve the power of the oils.
When you inhale the oil mist, your body absorbs the fine, pure particles, which has an immediate medicinal effect.

Caution: Traditional diffusers will have a very limited humidification capacity since their water tanks vary between 200 ml and 600 ml (far from the 2 to 6 l humidifiers). If you have a real need for humidification, it is better to move towards an ultrasonic humidifier with diffusion function.

Ultrasonic Air humidifier Diffuser Pack

Ultrasonic humidifiers with cold steam have a nebulizer just like the diffusers and they do not use heat. The absence of heat means that all the healing properties of the essential oil will be preserved in the expelled vapor.

However, it is recommended to purchase an ultrasonic humidifier with an essential oil tank independent of the water tank and designed from materials that will not be damaged by oils.

An air humidifier without diffuser function?

If you do not have a diffuser or humidifier with a tank for essential oils and you can not buy one at the moment, there is a way to experience the joys of aromatherapy with your ordinary cold or hot steam humidifier. You can soak a cotton ball with essential oil and place it on the steam outlet nozzle. This trick will diffuse the essential oil in the air to a certain extent, but obviously not as effectively as a diffuser.

It is quite useful to have a humidifier with essential oil diffuser function since the aromatherapy’s benefits are numerous. On the other hand, if you do not need a particular humidification for your interior (or maybe you even you have too much humidity), a simple essential oils diffuser will suffice.

What are the disadvantages of using essential oils directly in your air humidifier?

Plastics Corrosion

Because they are powerful, essential oils can cause serious damage to some humidifiers that are made of lower quality materials or which are simply unsuitable for aromatherapy. This is especially true if you use citrus essential oils, which are particularly harsh on plastics.

In addition, adding essential oils to your humidifier’s water tank can damage seals. Ultimately, this may result in leakage or complete failure of the humidifier.

Mist Finesse

Although humidifiers turn water into a fine mist, it’s not enough for essential oils. In order for your body to properly absorb the essential oil, the oil must be transformed into an extremely fine mist.

You will certainly feel therapeutic benefits but not as effective as with a diffuser.

Essential Oils Properties Alteration

If you have a hot steam humidifier, the use of essential oils with this type of device is a waste of money. The heat produced by the boiling water alters or destroys entirely the essential oils’ therapeutic properties. The room might smell good but your body will not benefit from any therapeutic benefit.

Oil Deposits on Your Furniture

The continued use of essential oils in a humidifier that does not have a function for that and hence does not separate them into superfine particles, causes long-term oily deposits throughout the home. The oil films accumulate on your furniture, your floors, your walls,etc.

Important Aspects and Functions That Make the Best Mist Humidifiers Diffusers Stand Out

Diffusion Method

Most models are equipped with a single nozzle through which flavor particles are released. More efficient models have two nozzles or a mobile deisgn that allows you to place the stream of mist and essential oil at any angle you need.

LED Display

Present in most electronic devices these days, a LED display provides extra functions for your misthumidifier diffuser. It can produce bright or diffused light, color animations and function as a night light. Some smart displays allow you more control over the whole experience: from changing colors to adjusting the mist stream.

Auto Shut Off

A particularly important function for the long and safe operation of the misthumidifier diffuser, the auto shut off automatically and quietly turns off the device when the tank is empty of water. Otherwise, the whole process would fail and you even risk a fire. The automatic shutdown function is especially practical at night, when your alertness is low.

Other aspects you should consider when investing in misthumidifier diffuser are: the machine should emit a low level of noise if you want to have a relaxing experience. Also, maneuvering the whole process with ease is essential, hence the device should be easy to fill, add oils, control and clean.

As you can see there are plenty of reasons to use a humidifier with essential oil diffuser function if you want to get the most benefits from the aromatherapy. The market has a huge variety of models available and in the following segment you can check some of the best.
