Electric Diffuser or Oil Burner: Which Is More Beneficial?

This is our comparison of electric diffusers vs. oil burners for essential oils.

As an aromatherapy enthusiast who researched what sets these two popular methods apart.

Both options can effectively diffuse pleasant scents and provide aromatherapy benefits. But the diffuser and burner have some key differences.

Electric diffusers feature cold air diffusion to preserve oil integrity. And oil burners utilize heat for fragrance dispersal at a lower cost.

While both can provide an enjoyable aromatherapy experience, the best method for you will depend on your specific needs.

Let’s explore how they work, compare the critical factors, and determine which type of diffuser provides optimal therapeutic qualities.

How Do Diffusers and Burners Work to Diffuse Essential Oils?

To understand which method may be better, we first need to understand how diffusers and burners work to disperse those aromatic essential oils into the air.

Diffusers Use Cold Air Dispersal

Electric diffusers utilize cold air and water to break down the essential oils into a fine vapor or mist. There are a few main types of electric diffusers:

  • Ultrasonic diffusers use electronic vibrations to create micro-particles of the water/oil mixture that then diffuse into the air. They come in decorative styles made of plastic, wood, glass or ceramic.
  • Nebulizing diffusers use pressurized air to blow across a tube of pure essential oil, turning it into a vapor that is potent but doesn’t use heat. They are made of glass.
  • Passive diffusers like diffuser jewelry or felt pads only require a few drops of oil directly on the material. Great for personal aroma but not whole rooms.

The key benefit of diffusers is that no heat is applied to the essential oils during the diffusion process. This preserves the natural chemical composition and therapeutic qualities of the oil.

Burners Use Heat to Diffuse Oils

Oil burners rely on heat to evaporate and diffuse the essential oils into the surrounding air. Some common types of burners include:

  • Tealight burners that use a small candle to heat a bowl of water and oil. These ceramic burners come in different styles but run the risk of cracking.
  • Electric burners use low heat from a lightbulb instead of an open flame, making them a bit safer.
  • Lamp ring burners attach around a light bulb on a lamp to heat and diffuse oil from the ring.
  • Wax melts are heated in a warmer device to release essential oil fragrance.

The potential drawback is that heating the oils could alter their molecular composition and reduce some therapeutic qualities. But burners effectively diffuse scent.

Safety Considerations of Diffusers vs. Burners

When choosing between diffusers and burners, it’s important to look at the safety factors especially if you have children or pets.

Diffusers are safer as there is no worry about open flames. Ultrasonic and nebulizing diffusers have auto shut-off features when the water runs low. Passive diffusers like jewelry pose basically no risks. Diffusers can be used bedside while sleeping without concern of fire.

Oil burners come with some cautions. The flame can pose fire risks if left unattended, spilled, or if oils are particularly flammable. Wax can also be dangerously hot. Burners require monitoring and may not be suitable around kids or pets who could accidentally knock them over.

If safety is your top concern, diffusers are likely the better choice over burners. But burners can be used responsibly by taking proper precautions.

Comparing Factors Between Diffusers and Burners

Aside from the diffusion method itself, there are a few other factors that may help determine whether to use a diffuser or burner.


Oil burners are often the more budget-friendly option, ranging from $5-$30 in most cases. Tealight burners are very inexpensive. Diffusers come in a wider range of prices, normally between $25 up to $100+ for high-end nebulizers. But you can find some basic diffuser models for $15 or under.

Usage Time

The burn time for a burner is limited by the candle, which will burn out in a few hours or less. Diffusers have much longer operation, typically running from 2-6 hours continuously or on intermittent settings. Auto shut-off gives peace of mind for extended diffusing. Burners require monitoring the candle.


Beauty is subjective, but many appreciate the soft lighting effect and ambiance created by a burning candle beneath a decorative ceramic burner. Reed diffusers can also provide pleasing visual appeal.

But modern diffusers come in very attractive styles that can complement home décor. Having options for colored LED lights is also a nice feature.


frequent cleaning is needed for oil burners to remove wax remnants and container soot after use. Diffusers only require occasional wiping and cleaning which makes maintenance simpler.

Effect on Therapeutic Benefits of Oils

One of the biggest considerations between electric diffusers and burners is whether the heat from a burner damages the natural therapeutic qualities of the essential oils.

Research shows that higher heat can start to degrade or alter the chemical composition and beneficial properties of essential oils. Heating may decrease antibacterial, anti-inflammatory, and other effects.

Diffusers work with cold air so the oil molecules remain intact, keeping their qualities potent. Ultrasonic diffusion is considered superior for retaining all of the natural benefits of essential oils for aromatherapy use.

If your main goal is to harness the therapeutic advantages, using an electric diffuser rather than a burner will give you the most advantages. The lack of heat keeps the oils closest to their natural state after distillation for the best aromatherapy experience.

Choose Electric Diffusers for Maximum Essential Oil Benefits

To summarize :

  • Diffusers utilize water and air to disperse oils as micro-particles. Burners rely on heating oils to diffuse their aroma.
  • Diffusers are safer for use around kids and pets due to no risk of fire. Burners require close monitoring.
  • Diffusers tend to cost more upfront but provide longer diffusion times. Burners are very affordable but limited by candle life.
  • For therapeutic advantages, diffusers are the clear winner. Heat from burners can diminish the natural benefits of the oils.

Ultimately, electric diffusers allow your essential oils to retain their highest quality and provide the most benefits. While burners effectively give off scent, the heating alters some properties. For the optimal aromatherapy experience and safety, electric diffusers like ultrasonic and nebulizers are your best option.
