The InnoGear® Wood Grain Ultrasonic Cool Mist Oil Diffuser is supplied within a plain brown cardboard box. Inside you will find…

The InnoGear diffuser wrapped in a plastic bag.

A bubble wrap bag containing a small plastic measuring jug and a power adaptor (that is also individually wrapped in a plastic bag).

Separately in the box you will also find an illustrated instruction leaflet that is entirely in English.



The device measures 12cm high and 17cm wide. (Measurements taken at greatest point).

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 20.11mm x 5.7mm.

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. 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

Pink > Orange > Red > Yellow > Light Green > Green > Turquoise > Mid Blue > Lilac > Purple.

and then the cycle 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 >Orange > Red > Yellow is incredibly fast, so much so that the colours orange and red are easily missed. All other changes take 1 or 2 seconds to blend from one to the other, but the change from pink to yellow takes less than a second.

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…

Bright red, dim red, bright lime green, dim lime green, bright green, dim green, bright turquoise, dim turquoise, bright dark blue, dim dark blue, bright lilac, dim lilac, bright white, dim white.

In some instances the difference between bright and dim does appear to actually be a different colour shade, but the fact is it is only a difference in light brightness.



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 to the marked max line which using the included measuring jug is exactly 300ml. Curiously the manual makes no mention of the quantity of oil that you should use however.

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. Only having reviewed a couple of larger diffusers in the past, I erred on the side of caution and went for 8 drops, which proved to be a wise move. If I had gone for a 5 drop to 100ml ratio the aroma would have frankly been unpleasant.


The diffuser has four mist functions available

Pressing the power button once and the mist function turns on and remains active for exactly one hour. Press the button twice and it will remain on for 3 hours, a third press and it will remain on for 6 hours. A fourth press and it will remain constantly on until switched off or the drain drains empty, a fifth press will switch the mist function off.InnoGear® Wood Grain Diffuser 19

The device has no high or low settings and whenever either of the buttons is pressed there is a clear audible 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. Due to its size and shape it also proves to be far more stable compared to smaller, taller diffusers. 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 26dBa to 27dBa 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 56dBa caused by water bubbling in the tank and the lowest recorded sound level was 40dBa.

At a distance of 177cm from the microphone to the edge of the device the highest recorded sound level was 30dBA and the average was 28dBA to 29dBa.

Compared to previous devices that I have reviewed, up close this one is on the loud side, but at a distance it is one of the more quieter devices. 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.

At a distance the InnoGear Wood Grain oil diffuser is the joint quietest differ I have tested alongside the Aiho AD-P6 diffuser although the AD-P6 is notably quieter up-close.

When the mist function is not active the device makes no noise.



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 0.9w and 1.2w from the socket. Given how long the Brennenstuhl can take to respond to changes and how fast some of the light changes are this reading is likely not 100% accurate.

With the mist function active and the light switched on in “blending” mode the device draws between 9.0w and 9.2w from the socket. Again given how long the Brennenstuhl can take to respond to changes and how fast some of the light changes are this reading is likely not 100% accurate.

When the mist function is active, but the lighting features are disabled the device draws 8.5w from the socket.

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

Bright red = 0.8w

Dim red = 0.6w

Bright lime green = 1.4w

Dim lime green = 0.9w

Bright green = 1.1w

Dim green = 0.7w

Bright turquoise = 1.6w

Dim turquoise = 1.0w

Bright dark blue = 1.0w

Dim dark blue = 0.8w

Bright lilac = 1.4w

Dim lilac = 0.9w

Bright white = 1.9w

Dim white. = 1.1w

Compared to similar devices these figures are about average, perhaps marginal erring on the high side, but we are talking about tenths of watts, which even in the grand scheme of things is negligible.
