Essential Oil Diffuser FAQ
Essential oil diffusers are an excellent addition to any room, but if you are new to essential oils, you may have questions before buying one.
1. What Is an Essential Oil Diffuser?
An essential oil diffuser is a small vapor misting machine that spreads the natural fragrance of essential oils throughout a room.
2. How Does an Essential Oil Diffuser Work?
Many of the best essential oil diffusers use the power of water to disperse essential oil or aromatherapy oil into the air. Wate- filled essential oil diffusers convert oil into tiny particles to blend with the water. A small mechanism heats the liquid gently, and this turns it into the mist released into the air.
Alternative essential oil diffusers called nebulizing diffusers to use an atomizer instead of water to create the most potent medicinal vapor. The atomizer breaks down the oil into microscopic particles suitable for misting in the air.
3. What Is the Purpose of an Essential Oil Diffuser?
The best essential oil diffusers are used to enhance the aroma of a room and to infuse the body with the natural healing properties of essential oils. Because diffusers emit a delicate essential oil vapor, the body absorbs the oil gently and beneficially. There are many benefits of using essential oils, and the type of oil you use determines its practical effects. Essential oils also help purify the air and may ward off pollutants like bacteria and fungus.
4. How Long Do Essential Oil Diffusers Last?
Essential oil diffusers come in different shapes, sizes, and tank capacities. The larger the tank, the longer a diffuser mists without requiring a refill. On average, a 200-milliliter tank lasts about four hours, and a 400-milliliter tank lasts around 8 to 12 hours before it needs refilling.
Many of the best essential oil diffuser options we’ve reviewed celebrate longer-lasting results because of the advanced technology used to build them. We found diffusers that last up to over 20 hours on one tank.
5. Is an Essential Oil Diffuser a Humidifier?
Often the best essential oil diffusers add moisture to the air, but only in small quantities. Some essential oil diffusers are better suited for humidifying a room. If you want to buy a diffuser that doubles as a humidifier, look for options with larger tank capacities. Usually, more prominent diffusers create more vapor output and will more effectively improve the humidity levels in the air.
We’ve included two of the best essential oil diffuser options for humidifying in our review below.
6. What Are Some Most Popular Essential Oils to Diffuse?
Selecting essential oils to diffuse is an entirely personal process that requires you to go inward. From your inner landscape, visualize the fragrances that most appeal to your senses. Often, the aromas that call to you have the medicinal properties you need. With so many incredible essential oils to choose from, sometimes a quick guide is the second-best place to start.
Below we’ll explore some of the most popular essential oils for different needs.
The warm floral scent of lavender is one of the most popular oils for reducing stress and the body and mind into a state of relaxation.
Tea Tree is a potent woodsy essential oil that is found in many medicine cabinets for its healing properties. When diffused, this oil is a powerful eliminator of airborne odor-causing bacteria.
The clean, fresh, and delightfully spicy scent of frankincense can soothe frazzled nerves and reduce symptoms of anxiety.
The sensuous citrus aroma of bergamot refreshes the air while bringing benefits to the skin, circulation, and improved sleep. Bergamot is also a powerful mood booster.
Natural eucalyptus has a sweet mint mixed with a pine scent that opens up nasal passageways, clears the lungs, improves headaches, and eases cold symptoms.
The clean pine needle smell of rosemary purifies the air while uplifting the mind, body, and spirit.
Earthy and floral, clary sage moves dense energy while relaxing the body. Clary sage helps with menstrual cramps, anxiety, and is also an aphrodisiac.
The sweet fragrance of rose essential oil beautifies rooms and helps with emotional support. We use rose essential oil in times of stress, healing, and emotional turmoil.
7. Where Can I Buy the Best Essential Oil Diffuser?
A variety of retailers sell the best essential oil diffusers, and Amazon has an incredible selection of diffusers for essential oils. Many large chain stores like Bed Bath and Beyond, Target, and Walmart sell aromatherapy oil diffusers.
