The InnoGear® 100ml Aroma Essential Oil Diffuser Electric Ultrasonic Cool Mist Humidifier is supplied within a plain brown cardboard box. On the front of the box is a sticker containing some product information and an illustration. Inside you will find…

The InnoGear diffuser is wrapped in a plastic bag. Under the diffuser protected within a cardboard insert and wrapped in plastic is a 150ml plastic measuring jug and a power supply. Loose within in the box you will also find an illustrated instruction leaflet that is entirely in rough English.



The device measures 19cm high at its greatest point (including feet) and 10.2cm in diameter at the base.

At the front near the base there are two buttons, on the left is the light button and on the right is the mist button, both buttons measure 10.57mm x 5.5mm and protrude by approximately 1.4mm.

The power brick protrudes from the socket by 5cm and measures 7.5cm tall. The power cable measures 173cm long excluding connector and cable reinforcement sections.



The device illumination feature is controlled by a single button on the base of the device that is marked “Light”. By default the light is off and the light can be operated entirely independently of the mist function if you just want a bit of mood lighting without the mist function.

Pressing the light button once and the light inside the device comes on, gradually blending from one colour to another. The sequence that I noted is as follows…

Turquoise, mid blue, dark blue, purple, lilac, white, pink, red, orange, yellow, lime green, light green, green. The Cycle then starts again.


All of these colour changes are a constant fading and blending from one colour to another and not remaining a single colour for more than a few seconds. The change from Pink >Red > Orange > Yellow however, is notably faster compared to the other colours.

Pressing the light button a second time will hold the colour of light shown at the time the button was pressed and the device will remain on that colour constantly.

Additional presses of the light button will manually change the light colour, selecting one of these options will leave the colour selected on constantly. The colours on offer are…

3rd press = Mid green, dull
4th press = Mid green, bright
5th press = Mid blue, dull
6th press = Mid blue, bright
7th press = Red, dull
8th press = Red, bright
9th press = Yellow (ish), dull
10th press = Yellow (ish), bright
11th press = Lilac, dull
12th press = Lilac, bright
13th press = Turquoise, dull
14th press = Turquoise, bright
15th press = White, dull
16th press = White, bright
17th press = switches the light off


It should be noted that the yellow colour from the InnoGear® 100ml Aroma Essential Oil Diffuser isn’t what many would call yellow.

At any time if you wish to turn the light feature off regardless what setting it is on just hold the light button down for 2 to 3 seconds.



I’ve lost count of how many essential oil diffusers that I have reviewed now, although its fair to say that it’s quite a few. During this time I have come to the conclusion that in terms of effectiveness they are so similar its impossible to compare one to another at least when comparing the time taken for an aroma to take hold and how long it lasts.

The truth of the matter is the oil used is far more important than the actual diffuser when it comes to the aroma. The only real difference is their size, how much water they hold, how much power they use and how loud they are in operation. As such the only things you need consider when buying a diffuser are as follows… the cost, the quality of construction, aesthetics, operational noise and power consumption.

Simply look for a diffuser that you like the look of, is in your budget and is a quiet as possible. Don’t use it on a side table next to your sofa, place it at least a couple of meters away if possible and invest in some quality oil, or better yet, try mixing your own. Anyway, rant over and on with some testing.

The manual advises that the device should be filled with 100ml of water and 0.1ml to 0.15ml of oil. Firstly, take care not to overfill the diffuser and remember the supplied jug is a 150ml jug. Also take care not to use too much oil, a good quality oil can easily become overpowering if too much is used.


The oil that I use is Fresh Skin Lavender purse essential oil and when testing diffusers with a 100ml tank I find that about 4 to 5 drops is optimal for a large room. With this particular diffuser the fan on the underside is quite large which is a good thing for noise level, but it makes little difference in the aroma produced.

The diffuser has three mist functions available…
Pressing the power button once and the mist function turns on with a green LED indicator that remains on while in use. In this mode the diffuser comes on for 30 seconds then shuts off for 30 seconds and then comes on again for another 30 seconds, etc, etc, etc. The manual does not state, but this model appears to run continuously until the tank is dry or it is manually switched off.

Pressing the button a second time and the LED indicator this time lights up red and the mist function remains on constantly until either manual switched off or the tank runs dry. A third press of the mist button will switch the mist function off.


The device has no high or low settings and whenever either of the buttons is pressed there is a rather unpleasant loud, high pitched beep confirming your button press.

On the underside of the device are three feet, these feet are fitted with silicone strips that offer a good degree of slip resistance if you try and push the device by hand. The gaps between the feet should also not be blocked; if they are it will affect the functionality of the device.



The following testing was conducted using an iPhone 6 and a cheap app. The figures are a guide only and I hold no responsibility for their accuracy. They are included as a guide only.

The ambient background sound level was 27dBa to 28dBa due to a ticking clock.

At a distance of 25cm from the microphone to the edge of the device the highest recorded sound level was 55dBa and the lowest recorded sound level was 54dBa.

At a distance of 177cm from the microphone to the edge of the device the highest recorded sound level was 29dBA and the average was 27dBA to 28dBa.

Compared to previous devices that I have reviewed, up close this one of the loudest oil diffusers that I have tested, but at a distance it is one of the quietest. The likely reason for the device sounding louder up close, but quieter further away is the frequency of the noise generated. Higher frequencies travel further and thus sound louder at a distance and lower frequencies sound quieter further away.

I will admit to being disappointed by the noise up close with this particular diffuser. The device has quite a large fan and larger fans can spin slower and thus generate less noise while producing the same effect as a smaller fan. Despite the large fan up close it is sadly quite loud.

When the mist function is not active the device makes no noise and as for that loud high pitch beep I mentioned when either button is pressed that registers 73dBA @ 25cm.



The following test results were obtained using a “Brennenstuhl PM 231 E Primera-Line Wattage Meter”.

With the device plugged in and none of the functions active the device draws 0.5w from the socket.

With the light switched on in “blending” mode and the mist function switched off it draws between 1.1w and 1.9w from the socket.

With the mist function active and the light switched on in “blending” mode the device draws between 9.3w and 9.7w from the socket.

When the mist function is active, but the lighting features are disabled the device draws 8.7w from the socket.

The following is a list of constant light modes and their power consumption readings without the mist features active.

Mid green, dull = 0.7w
Mid green, bright = 1.1w
Mid blue, dull = 0.9w
Mid blue, bright = 1.2w
Red, dull = 0.7w
Red, bright = 0.9w
Yellow, dull = 0.7w
Yellow, bright = 1.1w
Lilac, dull = 0.9w
Lilac, bright = 1.5w
Turquoise, dull = 1.1w
Turquoise, bright = 1.8w
White, dull = 1.2w
White, bright = 2.1w

Compared to similar devices these figures are slightly above average, but we are talking about tenths of watts, which even in the grand scheme of things is negligible.
