Table of contents

Speaking of essential oils, I can not help myself but i have to pay attention to a couple of facts. The first is the accuracy during the use of it, especially if you have kids at home. Carefully study the description, indications and contraindications, and other allowable concentrations and so on.

And the second one – buy only the licensed essential oils. Pay close attention to the quality of the box, it should contain the Latin title of the used plants, the place of production and the manufacturer. The price of essential oils directly depends on the method of production and availability of the source plant. Sometimes tons of plant raw materials are used to produce a several milliliters of essential oil. The price tag for those oils can reach thousands of rubles, and they are sold by the doses from 1 ml (for instance, rose, jasmine, neroli, ylang-ylang). Counterfeits are much cheaper, and pharmacies are literally overwhelmed with them.


AROFUME 400ml Ultrasonic Cool Mist Aroma Humidifier with Wood Grain – Best Essential Oil Diffuser of 2018

Aroma Humidifier with Wood GrainThe AROFUME Ultrasonic Cool Mist is a beautiful aromatherapy diffuser for a fair price.

It has a convenient size with a large 400ml reservoir (this is above the average for a device of this size).

It is very easy to turn off – It has only two buttons. One of them is used to control the humidification process itself, and the other is responsible for color settings. There are seven different colors of the outer LED rim – the whole rainbow. One short press will simply turn the lights on or change the color, and the continuous press will turn it off.

It has four timer settings: press the “Mist” button in order to select the timer – from one, three, six hours or just let it work until the water runs out by choosing the “ON” setting. One continuous press on the “Mist” button will make the aromatherapy diffuser cycle between the weak and strong mist.

It puts out too much moisture. Place a dry towel under it – and in an hour it will be completely soaked. I personally would like it to be more steady, because after the third hour of work it loses its effectiveness.

This looks good, it is safe and powerful and can be placed anywhere: not only at home, but in a hotel room, an office cabinet, a SPA salon, a hospital and in any other conditions that require refreshing air.

The package includes the aromatherapy diffuser itself, a convenient wall charger, a nice measuring cup for filling water and a user manual. It is nice that the device has 12-months warranty and 45-days money back – this is pretty generous for such a budget gadget.

Very nice budget device with a wooden housing. Looks much more expensive than it is, provides enough safety and has lots of adjustable features. I recommend it for everyone!

In the bottom half there is a fill line, which shows you the highest level of water. The device includes a smart fill cup, but you would have to fill it like five times in order to fill the reservoir of the diffuser, so it is probably better to use a big glass to fill this monster!

It stopped working after three uses. Very unfortunate! I had to wait for the replacement – I received it only after a month of waiting.

It is created using the traditional Chinese technologies in order to provide users with the best diffusing experience possible. I hesitated at first, but numbers of positive reviews made me buy this. I have never once regretted my decision – the level of comfort, which is provided by this diffuser, is beyond your highest expectations.

The diffuser is thoughtfully designed, it is very easy to work with and it doesn’t require any special treatment. Many other diffuses need to be used with the essential oil without any carriers. This is very wasteful, especially when you use some of the most expensive essential oils. Thankfully, Puzhen 5-Sense is using a reservoir filled with water, and you only need to add a couple of drops of the essential oil. One reservoir is enough for around 10 hours of work. You can also simply add water after 3-4 hours if you do not feel like wasting any more essential oil.

I am just in love with its built-in speakers. The device has an enormous library of various sounds (singing of birds, rustling of wind, sounds of forest etc.) – this is my weakness. I can listen to this all day long! You can even add your own tracks or simply plug in your smartphone.

The Puzhen 5-Sense Yun Aroma Diffuser can be controlled only with the remote. So if you lose it, the device practically becomes useless. Be careful with it!

Also, the price is just crazy. It can not worth so much money!

The device also has multicolored LED lights, that create a serene atmosphere, absolutely nullifying your stress.

The glass domed top is made of thick material and looks luxurious. The rest of the construction is made from quality maple wood.

Despite the enormous price tag, this device is very good. If you can afford it – buy it. You will not regret that, believe me!

The mist sometimes works and sometimes not… The unit can not work intermittently – this is very inconvenient. And what I do not like the most is that there is no way to turn off the light.

This is a very cheap device, sold at exorbitant price. You can find a better option for its money.

It is only ten years ago the aromatherapy of our house was limited with scented candles or air fresheners with changeable blocks. Not a very long time ago reed diffusers appeared in the line of aromatherapy products for home. They successfully occupied one of the leading positions on the market.

The history of essential oil diffusers roots back to more than a century. For many hundreds of years European people filled their houses with beautiful scents, using reed diffusers. In the ancient times Europeans used to fill empty vessels with olive oil, mixed with essential oils, and place reed in it. The sticks had been impregnated with an aromatic mixture and exuded a pleasant aroma. Since that time the operating principle of an aromatherapy diffuser practically does not change. Reed or rattan diffuser is a glass or a ceramic bottle with rattan sticks inside of it. Diffusers have various forms and sizes, does not require the special treatment and are safe, unlike the candles. The operating principle is simple – vessel with reed sticks in it is being filled with essential oils. Rattan has a porous structure and contains about 20-25 internal capillaries, which are used to rise aromatic oil. It permeates all the reed and gradually evaporates. If you want to enhance the aroma of the oil, simply flip over the sticks. The validity of such a device makes between one and six months of use, depending on the volatility of the oil used to create an aroma composition.

Essential oil diffusers are safe for environment, since they do not emit smoke or soot. Unlike many scented candles and essential oils, reed diffusers do not need an open flame to begin its work. If you have a working ion air purifier at home and you like to light candles, be ready for additional care about it. This does not apply to the use of essential oil diffusers, which does not affect air cleaners and humidifiers.

Reed sticks can have any length. The most important thing is that they do not have to be too short or too long, otherwise the aroma will be very weak. The number of rattan sticks usually ranges from 5 to 10 per bottle, although in this case it also depends on your desires.

Essential oil diffusers have gone beyond home use a very long time ago. Shop owners use them as a bait for customers. If you would feel a nice and gentle aroma in a store, you will stay there for a little big longer. Essential oil diffuser helps customers of beauty salons and massage parlors to relax. Real estate agents recommend to install aromatherapy diffusers in apartments for sale. Depending on the flavor, essential oil diffuser creates a unique atmosphere and mood. Noble scent helps to relax or energize, tune you to the romantic mood or relaxes your mind, lets you forget about everything or reminisce. All you need is to choose the right essential oil – there are plethora of them.

In order to choose the right size of the essential oil diffuser, Imagine the room, for which you are choosing the device. Small reed diffusers will suit bathrooms, not very big bedrooms and cabinets. The bigger the room – the more space is needed to be filled with aroma, so you would need a bigger essential diffuser for a spacious living room. They also vary in price – the cheaper the device, the less aroma it will produce due to the small amount of essential oil and reed sticks.

Buying guide. What is a diffuser?

An essential oil diffuser is the perfume for the house in a very unusual form. This is an elegant vial, filled with a bunch of natural oil-based flavors. In order to make the essential oil diffuser work, you should place reed or bamboo sticks in it. They are gradually saturated with the exciting smells and then gently spread it in the air.

After we learned, what an essential oil diffuser is, it is time to find out, where you can use it:

And, of course, an essential oil diffuser will be a perfect gift for loving person. Buy a stylish “home” perfume in a beautiful box for your significant other – it will be a win-win choice!

How to use an essential oil diffuser?

In the market of accessories home diffusers are yet a novelty, although humanity has been using them for more than two thousand of year. Modern aromatic bottles almost do not differ from their ancient predecessors, except for that now they have become more elegant and filled with exquisite compositions. Reed sticks are still used in essential oil diffusers in order to soak up essential oil and evaporate it from their surface.

There is nothing hard in the principles of operation of aromatherapy accessories. But we are still going to give some tips on how to properly use essential oil diffusers:

Stoneglow diffuser:

1) Open a new bottle and place the reed sticks. Wait for a little bit until they start to spread the scent around the whole room.

2) To increase the intensity of aroma, flip the stick from time to time. In order to decrease it remove a several sticks from the bottle – the lesser the surface of evaporation, the lighter the aroma.

3) Using natural essential oil diffusers, do not forget, that they are living. The bouquet changes over time: the lighter components evaporate and the composition shifts towards the heart notes and base persistent odors. This means that the time has come to change the bottle – remove the remains of the liquid and fill the bottle with a new mixture.

The average “life span” of a reed diffuser is from one to several months – all depends on the size of the bubble and the indoor climate. At high humidity the smell will be revealed slowly, with increasing temperature, it will become brighter, and a small bottle with essential oil diffuser will be quickly emptied.

Using it couldn’t be any easier – there is no complications. Just pour the water inside (up to 140 ml), add 5-10 droplets of essential oil (the number depends on the oil itself), connect it to an electric outlet and that’s all. The device is equipped with a power cord, which uses 120 V mains.

Almost immediately appears a nice mist, which will spread the aroma throughout the room without noises – the device is very silent.

And here are some moments due to which I particularly appreciated this device over the time. It is something I initially did not pay attention to, but later realized all the convenience:

Overall, the product turned out be excellent. At first I thought, that due to their warmth aroma lamps are better, than this “cold” essential oil diffuser, but after some time I realized that it is actually much more convenient and safer – that is why now I am using aroma lamps only as parts of decor. I use only the diffuser to vaporize essential oils – it is amazing.

Ultrasonic aromatherapy diffuser

My journey into the world of aromatherapy began a couple of years ago, when I really started to wonder, what do cosmetics consist of. I used to enjoy it and had lots of it. I began to study the composition of cosmetic products and learned about an extensive list of dangerous ingredients, that manufacturers of both mass-market and luxury production shamelessly add into their products. Of course, like many other people, I started to look for an affordable alternative among natural cosmetics. That is how I became interested in aromatherapy.

Aromatherapy studies essential oils, their compatibility and influence on human organism. Essential oils are complex, multi-component liquid mixtures of volatile substances with a pronounced flavor (do not mistake it with ordinary vegetable oils such as jojoba, grapeseed, macadamia and others.). They are produced from different parts of the plant – the flowers, leaves, roots, fruits, bark, etc… This is associated with different concentration of esters in different parts of the plant depending on the species. Not all plants are suitable for the extraction of essential oils. In most of them, the total concentration of essential oils is so low that oil production is either impossible or impractical.

Today only about 200 types of essential oils are produced on an industrial scale. All esters have a wide range of effects on humans, on both physical and the psychological level. This impact is not fully investigated – the same applies to all the components included in the composition of esters.

My research in aromatherapy are associated with specific urgent problems – the fight with viral diseases, combined and problem skin care, hair care, wound healing, etc. Although I do not create perfumes and complex aromatic mixtures, I had to dive into aromatherapy basics. Trust me, this is a very interesting – both in theory and in practice. Currently I am actively using essential oils. I have already found my favorites among them, but i still can not “find common ground” with some of the esters.

Essential oils are used for prevention and treatment of SARS, influenza and other catarrhal diseases (including in the official medicine). This is related to the fact that some of them have potent antimicrobial and antiseptic effect, some – strengthen the immune system, improve mood and self-esteem, thereby increasing the overall resistance to external negative factors.

Since one of the most effective ways of perception of essential oils – it is breathing, at first I used to “spray” the essential mixes with the aroma lamps. I used common ceramic ones: essential oil is being added to a small bowl of water, and then a candle is placed under it; under the influence of the flame water heats and evaporates from the bowl together with ethers. But, of course, it is not the safest and gentlest method of evaporating essential oils. Firstly – due to the open flames, and secondly – because of the heating of oils. Essential oils do not like high temperatures – their composition changes in the heat, some properties are lost and some obtained, and there is no guarantee that the oil will not turn from useful to useless or even dangerous. Most esters maximum allowable temperature – 40 Celsius degrees. In order to eliminate these unpleasant moments, I finally bought an essential oil diffuser in the last fall.

I didn’t spend much time choosing it – I was looking only for the type of spaying (I wanted to completely remove the heating of essential oils), design and the price tag. At last I chose an ultrasonic aromatherapy diffuser. It is a small and very cute pyramid, that looks like a tiny spaceship.

The mechanism and the operating principle of aromatherapy diffuser are very simple. Fist of all, it is worth mentioning that this is an electric device, that has to be connected to an outlet. The essential oil diffuser itself consists of the base and a cover.

The base includes a vessel with ceramic disc. This has to be filled with essential oils and water.

Ultrasonic waves divide this mixture into a plurality of microparticles, creating cold steam, thus ensuring the effective distribution of essential oils in the room.

The base of the aromatherapy diffuser is placed on four rubberized legs, and the power plug can be rotated in the socket at 360 degrees. The latter is especially convenient because it allows you to install the unit without the orientation on the cable exit of a base.

The order of use is extremely simple:

  1. Remove the conical cover from the base;
  2. Pour water into the bowl (up to 80ml The bowl has a line, whish shows the maximum water level.);
  3. Add from 3 to 5 drops of essential oil or oils;
  4. Close the lid;
  5. Connect the device to an outlet and press the power button.

This is it! The cold steam almost immediately begins to vaporize from the hole on the cover and you start to feel the esters flavor. When the mixture is completely “evaporated”, diffuser will automatically turn off.

The device if fully controlled by a single button, placed on the base of it (under the “Ultransmit” title). The first press activates the device – evaporation starts and lights turn on and begin to succeed each other. The second press will fix the color. Third press will turn the lights off (only the button and the joint of the base are still highlighted). The fourth press will turn the device off. Everything is very clear, logical and convenient. Nice!

The package of diffuser includes a box, a measuring cup and the instruction manual. The box is very beautiful and creative. It looks like it was made to be a perfect gift – apparently, diffusers are often bought as gifts :).

A couple of words regarding the mechanism

1) I quote: “the lack of heating increases the healing effects of essential oils.” To put it mildly, this is an exaggeration. No heating allows only to retain the same properties of oils without affecting their efficiency in any way.

2) The statement that essential oil diffusers “combine the properties of an aroma lamp and an air humidifier” is also an exaggeration. More precisely, it is an incorrect comparison of the properties. “Evaporation” of essential oils – is the main task of the diffuser, which it manages to do 100% effective and better, than aroma lamps. Humidification is just a positive side effect. Judge for yourself. Counting on my fingers: the diffuser evaporates 80ml of liquid for about 3 hours, it is 27ml / hour or 650ml / day. Let’s compare it with conventional air humidifier, for example, with such as I have – an ultrasonic humidifier Ballu UHB-900M. It evaporates 400ml / h or 9600ml / day. It turns out that the humidifier is about 15 times more efficient than a diffuser (in terms of water evaporation). Of course, this is related with the direct purposes of the essential oil diffuser, and with its power (12W against 135W of humidifier). Therefore, I repeat, do not believe the manufacturer claims that its diffusers are also humidifiers :). Everything is relative. But in general, of course, the evaporation of water takes place and it is a positive fact (especially in the context of our over-dried offices and apartments).

3) The manufacturer recommends to restrict “the use of citrus oils, since they are corrosive and their continuous use could cause damage to the device”. Citrus essential oils (orange, grapefruit, bergamot, lemon, mandarin, etc…) are most popular in aromatherapy and cosmetology. Almost all of them belong to the volatile esters and are perfectly combined with other essential oils. For many essential oils citruses are synergistic and / or complementary. In other words, they provide a systemic effect, amplifying the positive properties of the blend compared to the properties of its individual components. I love citrus esters and I can not imagine the aromatherapy without them :). Shortly speaking, I prefer not to pay attention to the warnings of manufacturer and I use citrus essential oils without any restrictions. If my diffuser will break down – well, I would have to buy a new one, but so far – everything is good.

For a single session in a room with a size up to 12 square meters 2-3 drops of essential oil are enough. The duration of treatment and the concentration of esters in the air depends on the amount of water poured into the cup before. 40ml evaporates for 1.5 hours, and 80 ml – for 3 hours, respectively, in the first case the concentration of esters in the air will be twice greater than in the second. I prefer the second option (lower concentration, but more prolonged exposure), so I always completely fill the bowl with water (80ml).

To the beginners in aromatherapy I advice to try these simple and effective mixtures for the prevention and combating SARS: fir and lemon, spruce and grapefruit, lavender and bergamot, tea tree and tangerine (choose the ratio yourself – 1:1, 1:2, 2:1). I have a little child (he is younger than two years old), this is why I don’t use complicated and exotic mixtures. The above mentioned ones are good enough.

Final Words – Conclusion

An essential oil diffuser is an innovative household appliance for flavoring rooms with aromatic oil. It connects to an electrical outlet and sprays essential oils using ultrasonic waves. Ultrasonic technology creates a permanent cold water mist, that allows the essential oils, diluted in water, to spread around the room.

Electric diffuser is a safe device, since it doesn’t heat up and automatically turn off as soon as the level of water in the reservoir is too low for properly functioning. Ultrasonic aromatherapy diffusers vary by their form, size, color and capacity. Any ultrasonic diffuser will give to your home the coziness and unusual aromas, created by the nature itself.

Advantages of diffusers

Firstly, the level of essential oil consumption is decreased when compared with other types of aroma devices. Secondly, the mixture does not heat up and, therefore, does not lose its useful properties – that’s why the choice of ultrasonic aromatherapy diffusor brings health benefits. Thirdly, due to the humidity sensor, the device will automatically go into the sleep mode and will turn on later by itself. It saves the essential oil and decreases the electricity consumption.

The diffuser will also shut off, when it runs out of liquid, notifying you with a sound signal. There is no heating and no open fire, but a reliable monitoring system. This isn’t surprising, that such a useful device as the essential oil diffuser is bought even for children’s room.

The highlight of the interior

The ultrasonic aromatherapy diffuser is made of modern materials and can have a lot of additional functions – such as a night lamp. And, that is most important, it looks very stylish. Especially it applies to devices of the French company “Esteban Paris Perfumes”. Under this brand you can buy an incredibly attractive model of an electric essential oil diffuser: you are able to choose from the futuristic to the romantic models, that will bring charm for your interior.

An electric diffuser will be exceptionally handy for the citizens of the biggest cities, where the air especially needs to be cleared and humidified. Indeed, these devices are mainly bought by urban residents.
