Why A Glass Oil Diffuser?

Glass essential oil diffusers have three pretty big advantages over other diffuser types:

  • Glass looks absolutely gorgeous.
  • Glass diffusers can cope with stronger oils. Plastic oil diffusers are sometimes recommended not to be used with strong essential oils (e.g. citrus-based essential oils).
  • Glass doesn’t contain toxins and thus can keep the oil purer.

Glass oil diffusers sure look great and don’t contain toxins or allergens as plastic does, but they have a huge downside – glass is brittle. This means that you may want to keep your glass oil diffuser out of reach of kids or pets.

Types Of Essential Oil Diffusers

Whether made from glass or not, there are four main types of essential oil diffusers – nebulizing, ultrasonic, heat, and evaporative oil diffusers. Each type has its good and bad sides, and it’s important to be aware of them. I wrote an article explaining home diffuser types in detail.

Nebulizing oil diffusers

Nebulizing oil diffusers employ pressurized air to break the essential oil down into tiny particles. Since no water or heat are used in these diffusers, the chemical composition of the essential oil stays unchanged. In the end, the undiluted essential oil has a noticeably more potent scent.

With that said, nebulizing oil diffusers are fairly pricey both upfront and in maintenance. Since essential oils are used as-is, without water, nebulizing oil diffusers run out of essential oil rather quickly. This will be a big problem for people on a tighter budget.

Ultrasonic oil diffusers

Ultrasonic oil diffusers also break essential oil down into tiny particles. But unlike nebulizing oil diffusers, ultrasonic diffusers use water and ultrasonic frequencies for essential oil delivery.

Since there’s water mixed in with the essential oil, ultrasonic diffusers use up less oil and are cheaper to maintain. Besides, the small amount of water delivered along with the essential oils has a humidifying effect, which may come in handy in drier areas.

With that said, the humidifying effect will probably be more problematic than helpful in already humid climates. Besides, the presence of water makes ultrasonic oil diffusers a little messier, and the oil diluted in water doesn’t deliver as potent of a scent.

Ultrasonic oil diffusers also require essential oils that are water-soluble, so you’ll need to be a bit careful when selecting essential oil for your diffuser.

Heat oil diffusers

Some essential oil diffusers employ heat to spread the scent. Some heat oil diffusers also use water, which allows for a humidifying effect and reduced expenditure of the oil.

Heat oil diffusers aren’t too expensive, and they don’t require too frequent replacement of oil. However, their biggest downside is that the produced heat can alter the chemical properties of the essential oil, reducing its therapeutic capability.

And needless to say, the heating device inside such oil diffusers poses a risk of fire, albeit insignificant.

Evaporative oil diffusers

Evaporative oil diffusers employ fans to assist with the spread of the scent in the room. The essential oil is applied to a built-in filter, and the fan blows air through it to encourage evaporation and spread the essential oil particles.

The biggest benefit of evaporative oil diffusers is that they are able to spread scent quickly, so they are great if you need a quick burst of aroma in the room. But they don’t deliver as longer-lasting scent as other oil diffuser types.

Evaporative oil diffusers also are the noisiest out there due to the fan. Not only that, but evaporative oil diffusers tend to disperse the lighter particles of the oil first, leading to a fairly uneven distribution of scent and oil.

And if an evaporative oil diffuser employs heat, then it also may alter the chemical composition of the essential oil and also be a fire hazard.

Things To Consider In Glass Essential Oil Diffusers

Essential oil diffusers are fairly simple devices, and there isn’t much to them. With that said, there are a few things for you to keep in mind when shopping for that best glass essential oil diffuser.

  • Type: Consider which of the described types the desired oil diffuser belongs to.
  • Intermittent spray mode: This feature delivers mist intermittently – for example, a diffuser with this feature may deliver oil for 15 seconds and then stop delivery for 15 seconds. Repeated intermittently, such an operation cycle allows for reduced essential oil usage.
  • Coverage: Coverage is usually indicated in square feet. This is the area that the aromatizing effects of a diffuser can be felt in.
  • Working time: Working time is an approximation of how long an essential oil diffuser will operate when filled. The working times claimed by manufacturers aren’t always precise, but they may be used for comparing diffusers with each other.
  • Timer: Some essential oil diffusers have a timer that allows you to run the device for a set amount of time.
  • Mood light: Essential oil diffusers typically have mood lights. This isn’t that big of a feature, but some people like oil diffusers that allow for mood light color adjustment. Besides, pay attention to whether the light can be turned off when misting – at night, for example, you wouldn’t want the light to disturb you.
  • Auto-shutoff: Essential oil diffusers also usually come with an auto-shutoff feature that shuts the diffuser down when there’s no water/essential oil inside.
  • Materials: While glass essential oil diffusers’ key component is glass, there may be some other materials present as well. Among the materials used in oil diffusers aside from glass is wood, plastic, ceramics, and metal.

If you have any specific needs, then be sure to have a look at what kind of materials the desired oil diffuser comes with.

Glass Essential Oil Diffuser Reviews

Shangmeite Glass Ultrasonic Essential Oil Diffuser

Up first on our list is this ultrasonic oil diffuser by Shangmeite.

The key feature of the Shangmeite glass essential oil diffuser is its intermittent mist mode. In this mode, the diffuser delivers oil in a 15 seconds on/15 seconds off regime, allowing you to conserve the essential oil. As Shangmeite claims, this essential oil diffuser has a working time of up to 8 hours in the intermittent mode.

You may also select the continuous mode if you don’t really care about oil savings.

Since this oil diffuser is ultrasonic, it also works as a humidifier. As we’ve explained above, ultrasonic diffusers are more efficient, though they do require water-soluble oils and also deliver less potent scents.

The Shangmeite glass oil diffuser has a 7-color LED light that can be operated separately from the mist mode. You may set the diffuser to a specific color, set color rotation, or shut the light off altogether.

Pros:

  • Efficient ultrasonic design.
  • Intermittent mist mode.
  • 7-color LED light that can be switched off while misting.
  • Works as a humidifier.
  • Auto-shutoff.

Cons:

  • No timer feature.
  • Requires water-soluble oils.

Aromis Nebulizing Glass Essential Oil Diffuser

If you want a little stronger fragrance and don’t really care about it being lost-lasting, then have a look at this nebulizing glass oil diffuser by Aromis.

Employing no water or heat, the Aromis essential oil diffuser promises to deliver fragrance just as your essential oil’s maker has intended it. The result should be the quick delivery of potent fragrance to your room.

This essential oil diffuser also has three intensity settings, allowing you to adjust the speed of the aroma delivery. Aside from that, this diffuser has a 10 minutes on/10 minutes off mode that automatically shuts off after 4 hours.

Also, Aromis also writes that this thing is perfect for areas sized at 30 x 30 feet (900 square feet).

What you might particularly like in this little diffuser as well is that it has no lights. This will be a downside for some people, but if you are looking to put your diffuser in the bedroom, then the absence of the light is great.

Aromis also boasts a natural wooden base in this essential oil diffuser, and it does look gorgeous. However, this diffuser is fairly pricey, partly precisely due to the quality wooden base.

Pros:

  • No lights.
  • Delivers a potent smell.
  • Intermittent misting mode.
  • Adjustable misting intensity.
  • No water required for operation.
  • All-natural materials.

Cons:

  • Pricey.
  • No built-in timers.
  • Runs out of oil relatively quickly.

Opulence Nebulizing Essential Oil Diffuser

This small and elegant essential oil diffuser again relies on the nebulizer technology, but it’s quite a bit different from the Aromis oil diffuser.

This thing, first of all, has a different intermittent misting mode. The Opulence oil diffuser diffuses oil for 2 minutes and shuts off for 1 minute. This cycle is repeated for 2 hours, after which the diffuser shuts off.

Being a nebulizing oil diffuser, the Opulence diffuser will deliver a more potent smell than what you’d get from other diffuser types. Opulence also writes that in ideal conditions, this diffuser can cover up to 800 square feet areas.

The Opulence glass oil diffuser has a built-in LED light as well, albeit it only has a white color. The light can be turned off, so if you are intending to use your diffuser in the bedroom at night, this essential oil diffuser should be able to work for you.

The build of the Opulence diffuser is also remarkable – this thing has no plastic and instead employs a glass top and a ceramic base. The flask shape of this diffuser is elegant and sleek as well. The price of this diffuser is equally remarkable – it definitely isn’t for those who are on a tight budget.

Pros:

  • Sleek design.
  • Delivers a strong smell.
  • Intermittent operation mode.
  • White LED light that can be turned off.
  • Requires no water.

Cons:

  • Fairly expensive.
  • No timer settings.
  • Eats through oil quickly.

Porseme Ultrasonic Glass Essential Oil Diffuser

The Porseme ultrasonic glass essential oil diffuser is the biggest oil diffuser on our list. Porseme claims that this thing will diffuse oil for at least 7 hours, but we think that it should do a few hours more no problem.

But it’s difficult to say how much area this diffuser will cover though since Porseme gives no numbers.

Aside from capacity, what this oil diffuser also boasts is 4 timer modes – auto/1h/2h/5h. The auto mode will run as long as there is water inside the diffuser.

The Porseme diffuser also has a 7-color LED light that can be set to a rotating or fixed mode, as well as shut off altogether. And being an ultrasonic diffuser, it also serves as a humidifier. A pretty inexpensive one, in fact!

Pros:

  • Efficient ultrasonic design.
  • Large capacity.
  • 7-color LED light.
  • Works as a humidifier.
  • Has 4 timer settings and auto-shutoff.

Cons:

  • Requires water-soluble oils.

EQUSUPRO Ultrasonic Glass Essential Oil Diffuser

Finally, we have this little guy that’s promised to cover up to 200 square feet areas. Not only that, it’s a good option if you are looking for a short burst of fragrance in the room since its time settings go from 0.5 to just 3 hours.

Other than the size and timer modes, this oil diffuser isn’t much different from the other ultrasonic diffusers already overviewed. It again has an auto-shutoff, 7 LED light colors, as well as works as a humidifier.

With that said, this thing is fairly inexpensive, so it should be a good option for buyers on a tighter budget.

Pros:

  • Efficient ultrasonic design.
  • 7 LED light colors.
  • 4 timer modes.
  • Works as a humidifier.
  • Has auto-shutoff.

Cons:

  • Relatively small capacity.
  • Requires water-soluble essential oils.

Final Words

Out of the 5 glass essential oil diffusers, the Porseme ultrasonic glass essential oil diffuser was the most well-rounded. At a fairly low price, it offers decent efficiency thanks to its ultrasonic operation. Besides, it has 280ml of capacity to deliver fragrance possibly all day long.

The other 4 glass essential oil diffusers are also great, but they aren’t as good all-around. Some of them sacrifice efficiency for a strong scent, while others are fairly efficient but have little capacity or functionality.

With that said, if you liked any of the remaining 4 oil diffusers more than our top pick, then feel free to pick it up instead!
