FAQ about Essential Oil Glass Diffusers (Nebulizers)


Few people know exactly what nebulizers are. Because this article is about them, I’ve put up this section of questions and answers. I’ll address everything related to a glass diffuser that comes to mind. Feel free to use the comments section to ask me new questions you can think of.


a) What exactly are glass essential oil diffusers?

Glass essential oil diffusers are totally made of glass. They have a glass container where you put the essential oils in. In a glass diffuser, there’s no need for water or other extra substances. These nebulizers don’t use heat either.


Cold vapors are the best at preserving the oil molecules and their benefits intact. That is also why today, glass Aromatherapy diffusers are the most advanced technology.


There are also diffusers that have plastic chambers and glass cases. But that is more the case with ultrasonic diffusers. The nebulizer term comes from medicine, but they are also known as atomizers or vaporizers.



b) How do glass diffusers work?

The glass reservoir of the nebulizer is connected to a compressor or pump. This pump causes the air to flow through the essential oil. That turns the oil into a beneficial mist (aerosol) of micro-molecules. They are then released through a glass lid.


This mist is loaded with active micro-droplets of essential oils that are very easy to inhale. A glass diffuser can be used for very large rooms as it has more power to disperse the oils effectively.


The manufacturer of an aroma glass oil diffuser should specify the way it needs to be used. But in general, you simply pour a small quantity of essential oils into the glass recipient.


For a smart diffusion, you should only keep the nebulizer on for 30 minutes at most. Turn it on again every 2 hours.


Why do I say smart diffusion? Because after 60 minutes of oil diffusion, the air becomes saturated. Your body will start reacting to this negatively. So, instead of being relaxed, joyous, etc. you’ll end up more agitated, stressed and your heart will beat faster.


This has been proven by many studies, where 10 – 20 minutes of inhalations were enough to reduce blood pressure and anxiety.


So no, it is neither wise, nor a good idea to keep your diffuser on continuously. Regardless of the type or brand it is. The diffusion should also be done in a room with good ventilation. Fresh air needs to be left to circulate and prevent air saturation. Air saturation may also lead to nausea or headaches.


You should also never use thick essential oils in glass diffusers. This includes blends with carrier oils too. Carrier oils are too thick and can clog the device. Plus, they are not volatile (don’t evaporate) and don’t have fragrances.

c) Why are glass diffusers expensive?

Glass oil diffusers are more expensive than your average diffuser for several reasons:


  • The materials needed are not cheap. Glass diffusers need good quality glass and wood to make resistant devices.
  • Glass essential oil diffusers don’t use heat. Because of that, the oil molecules and their properties are preserved intact, which no other diffuser does. Glass diffusers make Aromatherapy an efficient complementary therapy.
  • They don’t use water either, which means there is no risk of diminishing the effects of an oil. Oil molecules may stay suspended in the air and evaporate by the time they should get within your nose’s reach. Glass diffusers don’t change the level of humidity in the air.
  • Their aspect is very nice and elegant, which makes them good gift choices. These refined diffusers are also great décor pieces.
  • They can cover areas of up to 1076 sq. feet (100 sq. meters).


All these things make nebulizers superior even to ultrasonic diffusers. Therefore, a glass diffuser for essential oils will always cost more. Its benefits and advantages though, are well worth the investment. They are the best for therapeutic purposes.



d) How do you maintain and clean a glass diffuser for essential oils?

If handled and cleaned regularly, your glass oil diffuser should last a very long time. Their cleaning should be done as often as you use them.


Turning the diffuser on twice a day for instance, would not require cleansing. Yet, if you’re going to use it every other day or rarer, it should be cleansed before adding the oils.


The cleansing of a glass oil diffuser can be done in several ways:


  • If the glass recipient is not too dirty, you can pour 1 ml of pure alcohol in it and turn it on for 2 minutes. Do not use water in this process. I haven’t yet tested this method, but the French did and it worked. Alcohol should dissolve the oil leftovers and leave the glass recipient clean.
  • Take the recipient out and wash it gently with a glass solution and lukewarm water.
  • You could also leave some glass cleansing solution in the recipient overnight and rinse the next day.
  • Vinegar solutions may also work.


Glass essential oil diffusers must be cleansed often to ensure proper oil diffusion.



e) What makes essential oils so good for diffusion?

Essential oils are concentrated herbal essences. They are extracted via steam distillation from various plant parts. These oils are composed of tens of active chemical constituents. Each one has its own specific characteristics and effects on the human body, skin and nervous system.


A nebulizer will break the already tiny molecules of the oils into micro-droplets. These droplets are easier to inhale, thus they make it into the body faster. This also results in them working faster.


The inhalation/diffusion of essential oils has a rate of absorption of about 70%. This means that 70% (which is a very good percentage) of the oil molecules will get into your system. They can’t enter the body 100% unless they’re injected, which is not an option.


The benefits and effects of an aromatic essence depend on the essence itself. But generally speaking, essential oils can:


  • Protect and/or treat infections.
  • Prevent viral infections such as colds, the flu, etc.
  • Soothe inflammations.
  • Kill bacteria and fungi.
  • Stimulate and strengthen the immune system.
  • Uplift and improve your mood.
  • Help with concentration.
  • Help with insomnia.
  • Improve anxiety.
  • And so much more.



f) Why is a glass recipient better than a plastic one for essential oils?

Pure essential oils are always kept in dark, glass bottles. The reason for that is that, in time, they can dissolve the plastic. They do not interact with the glass, which preserves them as they are. This way, there is no risk in them damaging the device.

With all the questions and answers about nebulizers out of the way, it’s time to get to more pressing matters. Next, you’ll be reading about the pros and cons (and some personal thoughts) about some of the best glass aroma oil diffusers.



1) Raindrop 2.0 Nebulizing Essential Oil Diffuser for Aromatherapy 

This is a very cute and chic glass essential oil diffuser. The Raindrop Nebulizer promises 100% guaranteed satisfaction.

Glass Essential Oil Diffusers, Raindrop 2.0 Nebulizer



  • The manufacturer offers 1 year free parts & service warranty.
  • The device is “ultra-durable and whisper-quiet”.
  • It also has many beautiful LED colors to choose from that can be turned on/off.
  • It has 2 operating cycles: 2 minutes on, 1 minute off or 2 continuous hours. After these 2 hours, it shuts off automatically.
  • The glass recipient is hand-blown and the support is 100% plantation hardwood. The wood is painted with water based lacquer that doesn’t release harmful gasses.
  • The measurements of this glass essential oil diffuser are 5 inches wide (13cm) and 9 inches tall (22 cm). The models however, vary.
  • The Raindrop nebulizer works on 110-220v electric systems.
  • The manufacturer recommends the cleansing of the glass reservoir once a week. For that, he recommends the use of isopropyl alcohol.
  • They also promise “rock-solid after-sale customer support”.
  • The diffuser may cover ranges of up to 800 sq. feet (70+ sq. meters).



  • For two continuous hours of diffusion, you must use about 20 – 25 drops of essential oil. This means that, depending on how often you use it, you’ll go through oils very fast. However, for the recommended half hour diffusion, you should be good with 8 – 10 drops only.
  • The fragrance released may be affected by the quantity of oil used.
  • The device should not be kept on in a small, enclosed room, even if it’s well ventilated. It may be too powerful, though if you add only a small amount of oils, the smell will also be weaker.
  • The glass is fragile and may break easily if not handled with care. Keep it some place high and out of easy reach.


Why I like it:

The design is very pretty and looks great wherever is kept. It can also be moved from room to room, though I would not recommend it too often. The Raindrop Nebulizing Glass Essential Oil Diffuser could make a great gift idea.
