Essential Oil Diffusers DEFINITION Diffusion is the process of dispersing essential oils so that their aroma fills a room or an area with the natural fragrance. From the simple to the elaborate, many different methods exist for diffusing oils into a room. Three easy methods exist which can be done with things you probably already have in your household. In addition, there are numerous diffusers and diffusing devices available for purchase from aromatherapy vendors. This article will detail the different types of devices and methods that may be used. Methods That Can Be Done With Items Already in Your Household Simple Tissue Diffusion ============== Place 3-4 drops of essential oil on a tissue. Place the tissue near you. As movement occurs in the room (i.e. as you move or as someone walks by), you will notice the aroma. * Advantages: This method can be used anywhere and is quickly transportable. * Disadvantages: This method does not emit much aroma into a room. Steam Diffusion ========== Boil 2 cups of water. Pour the water into a bowl and add up to 10 drops of oil to the water. Use fewer drops if you are using an oil that may cause irritation to your mucous membranes (i.e. cinnamon, eucalyptus, rosemary, pine, thyme, cajuput, etc.). Use of energizing or relaxing oils can make this method useful any time of day or night. The steam will heat the oils and cause them to evaporate quickly into the room. * Advantages: This method will quickly diffuse the oils into a room. * Disadvantages: The aroma is not exceptionally long-lasting. Additionally, the heat may alter or destroy certain constituents of the oils and thus the therapeutic benefit may not be as optimal as using cold-air diffusion methods. Candle Diffusion ========== Light a candle and allow it to burn for about 5 minutes. Extinguish the candle, place 1 drop of essential oil in the melted wax (not on the wick!) and then relight the candle. Essential oils are highly flammable, so great care must be used. * Advantages: This method can be used most anywhere that a candle may be used. * Disadvantages: Essential oils are flammable, so great care must be used. The aroma is not long-lasting. The heat may alter or destroy certain constituents of the oils and thus the therapeutic benefit may not be as optimal as using cold-air diffusion methods. Diffusers and Diffusion Products on the Market ++++++++++++++++++++++++++++++++ The descriptions below are generalities about the different products that are available. Always check the specifications, requirements and safety comments supplied with the particular product you are interested to confirm that it is suitable for your needs and expectations. To locate vendors that sell diffusers, visit the Diffusers & Nebulizers Category of AromaWeb's Business Plaza. Lamp Rings ======= Lamp rings are a terra-cotta ring that sets directly onto a light bulb. It has a grooved lip that goes all the way around it. This lip holds essential oil. The heat from a light bulb heats the essential oil in the Lamp Ring and the oil is then gently diffused into the room. * Advantages: Lamp Rings are usually very inexpensive. * Disadvantages: If any essential oil gets onto the light bulb, the light bulb could break. The heat may alter or destroy certain constituents of the oils and thus the therapeutic benefit may not be as optimal as using cold-air diffusion methods. Clay Pot Diffusers =========== Clay pot diffusers go by many names, but they resemble small terra-cotta pots. They also can be found in various small shapes such as pyramids. A clay pot diffuser contains an opening for adding essential oils. Usually a cork is the method by which the opening is closed. The oils permeate through the pot and then diffuse out into the room. The intensity of the aroma depends on how much essential oil is added to the clay pot. * Advantages: Clay pot diffusers are very inexpensive, easy to use, and do not require electricity or batteries. * Disadvantages: The aroma is strongest shortly after adding essential oil to the clay pot and then dissipates as time passes. As such, it’s hard to keep the same level of aroma in the room. Candle Diffusers ========== A candle diffuser is a diffuser that utilizes a tea light or other candle to gently heat the essential oil to promote diffusion into a room. A candle diffuser is usually ceramic or metal. The diffuser has an opening or space for a candle and a little bowl or tray for storing a tiny quantity of essential oil. Candle diffusers come in many shapes and colors from the modest functional piece to the piece that acts both as a work of art and as a candle diffuser. * Advantages: Candle diffusers can be inexpensive, depending on the style and design. Candle diffusers do not require electricity or batteries. * Disadvantages: One needs to be as careful with using a candle diffuser as with using candles in general. Also, one must be sure to keep replacement candles on hand. The aroma generally diffused by a candle diffuser is very light and it does not usually diffuse an entire room. The heat may alter or destroy certain constituents of the oils and thus the therapeutic benefit may not be as optimal as using cold-air diffusion methods. Fan Diffusers ======== Fan diffusers come in a variety of sizes, shapes and styles. A fan diffuser uses a fan to blow the essential oils into the air. To use a fan diffuser, essential oils are usually placed onto a disposable absorbent pad or into a tray. The pad or tray is placed into the unit and then powered on. The fan then blows air across this pad or tray and carries the aroma throughout the room. Since fan diffusers come in a variety of sizes, some fan diffusers will only diffuse a small room whereas others can diffuse very large areas. Some fan diffusers require the use of an absorbent pad (the pads can usually be reordered from the retailer or directly from the manufacturer). In others, the use of absorbent pads is optional. * Advantages: Fan diffusers are available in a wide variety of brands and styles. Depending on the brand and model, fan diffusers can fragrance a large area. Fan diffusers are generally easy to use. Some fan diffusers are powered by both electricity and batteries making them quite portable. * Disadvantages: Some fan diffusers, depending on the brand and model, require the purchase of replacement absorbent pads. Some fan diffusers are noisy. Electric Heat Diffusers ============= Similar to a fan diffuser, heat diffusers use heat and a fan to gently heat the oil and disperse the aroma into a room. * Advantages: Electric heat diffusers may fragrance larger areas, depending on the brand and style. They can also help to more efficiently disperse the aromas of thicker oils such as Sandalwood and Patchouli. * Disadvantages: Heat may alter or destroy certain constituents of the oils and thus the therapeutic benefit may not be as optimal as using cold-air diffusion methods. Nebulizers ====== A nebulizer is a device that takes essential oils and breaks them into separate molecules before dispersing the smaller molecules into the room. It is said that these smaller molecules can be more readily absorbed by the lungs and thus create greater therapeutic value than by use of other diffusion methods. A nebulizer is a small (perhaps 8" x 4" x 6") device that consists of two main parts: the plastic base that contains the motor and a very unusual, clear blown-glass looking device that holds and "nebulizes" the oils. Instead of the use of the unusual glass piece, some nebulizers use a special bottle that looks like a Boston round bottle. * Advantages: It is said that nebulizers can supply greater therapeutic benefit than the use of other diffusers because they break the oils down into smaller molecules. * Disadvantages: The glass piece is breakable and expensive to replace. Compared to other methods, cleaning the glass between different oils is time consuming. Depending on the style nebulizer, thick oils such as Sandalwood and Patchouli usually cannot be used as they can clog certain style nebulizers. For Those Who Own a Food Dehydrator ++++++++++++++++++++++++++++ I do not recommend purchasing a food dehydrator for diffusion purposes as it is a little bulky and cumbersome for this purpose. If, however, you already own a food dehydrator, you may have nice results in using it as an alternative to diffusing EOs. Excalibur, makers of high-end food dehydrators, say that you can dry evergreen branches directly in the machine to experience the aroma. They also mention that you can place a wet sponge with a few drops of oil on it (they say vanilla extract, but this should work with EOs) into the dehydrator. It goes without saying, however, that you should follow all safety precautions and instructions for your dehydrator model and only leave your dehydrator running for this purpose for a short period of time.
