The Best Essential Oil Diffuser Buying Guide and Use Tips

Aromatherapy is a wonderful natural therapy that has gained popularity in recent years. It operates on the belief that certain scents can have positive effects on our overall well-being, from our physical health to our emotional state. You can diffuse these fragrances in a variety of ways, such as through scented candles, incense, or essential oil diffusers.

If you’re considering purchasing an essential oil diffuser, you’ll be amazed by the wide range of options available on the market today. There are countless types, styles, and designs to choose from, each with its own unique features and benefits.

What Is An Essential Oil Diffuser?

An essential oil diffuser is a device that is used to disperse essential oils into the air. These devices come in a variety of shapes, sizes, and styles, but they all work in the same basic way: they use heat, water, or air to release essential oil particles into the air, where they can be inhaled or absorbed through the skin.

Essential oil diffusers are often used for aromatherapy, which is a natural therapy that uses fragrances to promote physical and mental well-being. When essential oils are diffused, they release aromatic molecules that can have a range of effects on the body and mind, depending on the specific oil used.

Some essential oil diffusers use ultrasonic technology to break down the oil particles into a fine mist that can be easily absorbed by the body. Others use heat to evaporate the oil, while some use a fan to blow air through a pad that has been infused with the oil.

Overall, an essential oil diffuser is a great way to enjoy the benefits of aromatherapy in the comfort of your own home.

There are numerous benefits to using an essential oil diffuser, including:

  • Aromatherapy: Essential oil diffusers are commonly used for aromatherapy, which can help promote relaxation, reduce stress and anxiety, and improve mood.

What To Consider When Buying An Essential Oil Diffuser?

When buying an essential oil diffuser, here are some factors to consider:

Type of Diffuser

There are four main types of essential oil diffusers: ultrasonic, nebulizing, evaporative, and heat diffusers. Each has its pros and cons, so consider which one is best for your needs.

  • Ultrasonic diffusers: These use ultrasonic vibrations to create a fine mist that disperses the essential oils into the air. Ultrasonic diffusers are quiet, easy to use, and often come with different lighting options.
  • Nebulizing diffusers: These break down the essential oils into a fine mist without the use of heat or water. Nebulizing diffusers produce a strong concentration of essential oil and are ideal for therapeutic purposes, but they can be noisy and more expensive than other types.
  • Evaporative diffusers: These work by using a fan to blow air through a pad or filter that has been soaked in essential oils. As the air passes through, it picks up the scent of the oils and distributes them into the room. Evaporative diffusers are simple to use and affordable, but they don’t offer the same level of therapeutic benefits as other types.
  • Heat diffusers: These use heat to vaporize the essential oils and release them into the air. Heat diffusers are simple to use and affordable, but they may alter the chemical composition of the oils and reduce their therapeutic benefits. They can also be a fire hazard if left unattended.

Room Size

Consider the size of the room where you plan to use the diffuser. Some diffusers are better suited for smaller spaces, while others can cover larger areas.
For a small room, such as a bathroom or office, a diffuser with a capacity of 100ml or less would be sufficient. For medium-sized rooms, like a bedroom or living room, a diffuser with a capacity of 200-300ml would be suitable.

If you have a large room or open-concept living space, you may want to consider a diffuser with a larger capacity, such as 500ml or more.

Keep in mind that a diffuser’s coverage area can also vary based on the type of diffuser and the strength of the essential oils used. Some diffusers may have a maximum coverage area of 100 square feet, while others can cover up to 1000 square feet.

It’s important to read the manufacturer’s specifications and recommendations for each diffuser to ensure that it will work effectively in the size of the room you plan to use it in.


The shape of an essential oil diffuser can play a role in its functionality, as well as its design and aesthetic appeal. Here are some common shapes of essential oil diffusers:

  • Round: Round diffusers are a popular shape, as they are often compact and easy to use. They typically have a small base and a rounded top and can come in a variety of materials and designs.
  • Cylinder: Cylindrical diffusers have a more modern look and can come in a range of sizes. They are often taller and slimmer than round diffusers, with a longer run time due to their larger water capacity.
  • Square: Square diffusers have a more angular and modern design, and can come in a range of sizes. They often have a flat base and a square top, with a larger water capacity for longer run times.
  • Egg/Oval: Egg or oval-shaped diffusers are often compact and have a unique look. They can come in a variety of materials and designs and are a good choice if you want a diffuser that is both functional and aesthetically pleasing.
  • Specialty: Some diffusers come in unique shapes, such as lotus flowers, animals, or other decorative shapes. While these diffusers may be more visually appealing, it’s important to ensure that they are also functional and safe to use.

Ultimately, the shape of an essential oil diffuser is a matter of personal preference and style. Consider the space where you plan to use the diffuser, as well as your personal taste when choosing a shape that fits your needs.


The material of an essential oil diffuser is another important consideration when choosing one. Here are some common materials used in essential oil diffusers:

  • Plastic: Many diffusers are made of plastic, which can be durable and lightweight. However, some people prefer to avoid plastic due to concerns about potential toxins or environmental impact.
  • Glass: Glass diffusers are often more fragile than other materials, but they can be visually appealing and may be a good choice if you want a diffuser that looks elegant and sophisticated.
  • Ceramic: Ceramic diffusers are popular because they are both durable and visually appealing. They can come in a range of colors and designs, making them a versatile choice for different decor styles.
  • Wood: Wooden diffusers have a natural look and feel, making them a good choice if you prefer a more organic aesthetic. They are often handcrafted and can come in a variety of woods and finishes.
  • Metal: Metal diffusers, such as those made of stainless steel or brass, can be sleek and modern in appearance. They are often durable and long lasting, making them a good investment.

Consider the durability, visual appeal, and environmental impact of the materials used in an essential oil diffuser when choosing one. Ultimately, the choice of material will depend on your personal preferences and needs.


Runtime refers to the amount of time a diffuser can operate before it needs to be refilled with water and/or essential oils. Check the runtime of the diffuser to ensure it will run for as long as you need it to. Some diffusers can run continuously for several hours, while others have shorter runtime.

Some diffusers can run continuously for up to 10 hours or more, while others may have a shorter runtime of only a few hours.

If you plan to use your diffuser throughout the night while sleeping, look for one with a long runtime or a timer function that will automatically shut off after a certain amount of time.

Keep in mind that diffusers with longer runtimes may have larger water reservoirs and take longer to fill, while diffusers with shorter runtimes may require more frequent refilling. It’s important to balance the runtime with the size of the room and your personal needs to ensure that you are getting the most out of your diffuser.

Water Capacity

The water capacity of an essential oil diffuser will impact its runtime. A larger water tank will generally allow for a longer runtime, while a smaller tank may need to be refilled more frequently.

A larger room may require a diffuser with a larger water tank to effectively disperse the essential oils throughout the space.

A larger water tank can run for an entire day without refilling. However, it is not convenient for moving frequently or switching up scents often. Also, it can also mean more maintenance, as it will need to be cleaned more frequently to prevent the buildup of mineral deposits or other debris.

Noise Level

The noise level of a diffuser can be an important factor to consider, especially if you plan to use it in a quiet space like a bedroom or meditation room. Some diffusers can be quite loud, which can be distracting or disturbing if you plan to use it in a quiet space like a bedroom. Look for a diffuser with a low noise level if this is a concern for you.

Ultrasonic diffusers are typically the quietest type of diffuser, producing only a soft humming sound that is barely noticeable. Nebulizing diffusers can be louder due to the air pump that is used to force the essential oils through the diffuser. Evaporative diffusers can also be noisy due to the fan that blows air through the essential oils.

When choosing an essential oil diffuser, look for one with a low noise level, typically below 35 decibels. Some manufacturers may list the noise level of their diffusers in the product specifications. Additionally, consider the location of the diffuser in your room. Placing the diffuser on a soft surface like a rug or cloth can help to absorb some of the noise.


Essential oil diffusers come in a range of designs, from sleek and modern to more rustic or natural-looking. Consider which design will best fit your personal style and home decor.

The style of an essential oil diffuser is another important consideration when choosing one. Here are some common styles to consider:

  • Modern: Modern diffusers are often sleek and minimalist in design, with clean lines and neutral colors. They can be a good choice if you prefer a contemporary look.
  • Rustic: Rustic diffusers often feature natural materials like wood or stone and may have a more organic, handmade feel. They can be a good choice if you prefer a cozy, rustic aesthetic.
  • Decorative: Some diffusers are designed to be visually striking and can serve as a decorative accent in a room. They may feature intricate designs, bright colors, or unique shapes.
  • Classic: Classic diffusers often have a timeless, traditional look that can fit in with a range of decor styles. They may feature ornate details or classic shapes.

Consider what style will best complement your existing decor and personal preferences when choosing an essential oil diffuser. Keep in mind that the style of the diffuser can impact its functionality as well, so choose one that meets both your aesthetic and functional needs.


Many essential oil diffusers come with built-in LED lighting, which can add to the ambiance of a room and create a soothing, relaxing atmosphere. Here are some things to consider when it comes to diffuser lighting:

  • Color: Some diffusers allow you to choose the color of the LED lighting, while others cycle through a range of colors. Consider what colors you find most relaxing and choose a diffuser that offers those options.
  • Brightness: The brightness of the LED lighting can also vary between diffusers. Some have a dimmer switch that allows you to adjust the brightness, while others have a fixed brightness level.
  • Functionality: Some diffusers have lighting that can be turned off or on separately from the diffuser function, while others require the lighting to be on in order to run the diffuser. Consider what functionality is most important to you when choosing a diffuser with lighting.
  • Mood lighting: Some diffusers offer lighting options that are specifically designed for creating a relaxing, meditative mood. These may include slow color transitions or gentle pulsing of the light.

Ultimately, the lighting features of an essential oil diffuser are a matter of personal preference. Consider what features will help you create the most relaxing and enjoyable atmosphere in your space when choosing a diffuser with lighting.

Auto-Off Feature

An essential oil diffuser with an auto-shutoff feature is designed to automatically turn off the diffuser when the water level is low or when the diffuser has been running for a certain amount of time. This is an important safety feature that helps prevent the diffuser from overheating or running dry, which can damage the diffuser or pose a fire hazard.

The auto-shutoff feature can also help conserve essential oils and water and prolong the life of the diffuser. When choosing an essential oil diffuser, it’s recommended to look for one with an auto-shutoff feature to ensure safe and efficient use. Some diffusers may also have adjustable auto-shutoff settings, allowing you to customize the runtime to suit your needs.


Essential oil diffuser portability refers to the ability to easily move and transport the diffuser from one location to another. Portable essential oil diffusers are very convenient if you plan to use your diffuser in multiple rooms, travel with it, or take it to work. They are usually smaller in size and lightweight, making them easy to pack and carry.

Some portable diffusers may also have features like rechargeable batteries or USB connectivity for added convenience. When choosing a portable diffuser, consider factors like size, runtime, and ease of use, as well as any additional features that may be important to you, such as auto shut-off or adjustable mist settings.

Brand Reputation

Choosing a brand with a good reputation can help ensure that you are purchasing a high-quality and reliable essential oil diffuser. Research the brand’s customer reviews, quality, warranty, customer support, and sustainability practices to make an informed decision. Here are some factors to consider when evaluating a brand’s reputation:

  • Customer reviews: Look for customer reviews of the brand and its products. Check online reviews and forums to get an idea of how satisfied customers are with their diffusers.
  • Quality: Research the quality of the brand’s diffusers. Check for features such as auto shut-off, timer settings, and mist intensity options.
  • Warranty: Look for a brand that offers a warranty on its products. This can give you peace of mind in case anything goes wrong with your diffuser.
  • Customer support: Consider the level of customer support offered by the brand. Look for a brand with responsive customer support that can answer any questions or concerns you may have.
  • Sustainability: Consider the brand’s commitment to sustainability and eco-friendliness. Look for a brand that uses sustainable materials and has eco-friendly practices.


Essential oil diffusers are typically compatible with a wide range of essential oils. Ensure that the diffuser is compatible with the essential oils you plan to use. Some diffusers may not work well with thicker oils or certain blends. However, it’s important to check the manufacturer’s instructions to ensure that the oils you plan to use are safe and appropriate for use with your diffuser.

Here are some things to keep in mind when considering the compatibility of essential oils and diffusers:

  • Oil types: Some essential oils, such as citrus oils, can be corrosive to certain types of plastic or rubber. If your diffuser has parts made from these materials, check to ensure that the oils you plan to use are safe for use with them.
  • Concentration: Different essential oils have different concentrations and strengths. Make sure the diffuser you choose is capable of handling the concentration of the oils you plan to use.
  • Blends: Some essential oils are often used in blends with other oils to create a specific scent or therapeutic effect. Ensure the diffuser you choose can handle the specific blend of oils you plan to use.
  • Quality: The quality of the essential oils you use can also impact their compatibility with a diffuser. Choose high-quality oils that are pure and free from contaminants.

Cleaning: Make sure to clean your diffuser regularly, as residual oil buildup can impact its performance and longevity.

Safety Tips

Here are some essential oil diffuser safety tips to keep in mind:

Read and follow the manufacturer’s instructions carefully, including any warnings or precautions.

  • Read and follow the manufacturer’s instructions carefully, including any warnings or precautions.
  • Only use high-quality, pure essential oils that are intended for aromatherapy use. Do not use fragrance oils or oils that are not intended for use in a diffuser.
  • Always use the recommended amount of essential oils for your diffuser. Start with a small amount of essential oil, such as 3-5 drops, and adjust as needed.

  • Do not ingest essential oils or allow them to come into direct contact with your skin or eyes. If accidental ingestion occurs, seek medical attention immediately.
  • If you have respiratory issues or are pregnant, consult with a healthcare professional before using essential oils in a diffuser.

By following these safety tips, you can enjoy the benefits of aromatherapy and the use of essential oils in your diffuser while minimizing the risk of adverse reactions or accidents.

How Many Drops of Essential Oil Should I Put in A Diffuser Each Time?

The number of drops of essential oil you should put in a diffuser each time can vary depending on the size of the diffuser and the strength of the oil. As a general rule of thumb, you can use the following guidelines:

  • For a small diffuser (100ml or less), use 3-5 drops of essential oil.
  • For a medium-sized diffuser (between 100ml and 300ml), use 5-7 drops of essential oil.
  • For a large diffuser (300ml or more), use 7-10 drops of essential oil.

However, it’s important to note that some essential oils are stronger than others, so you may need to adjust the number of drops based on the oil you use. For example, oils like peppermint or eucalyptus can be quite strong, so you may only need to use 1-2 drops in a small diffuser.

It’s also a good idea to consult the manufacturer’s instructions for your specific diffuser, as they may have recommended guidelines for the amount of oil to use. And always remember to follow proper safety precautions when using essential oils, such as keeping them out of reach of children and pets, and not ingesting them.

What Essential Oils Should Not Be Used in Diffusers?

While most essential oils can be used safely in a diffuser, there are a few oils that should not be used or used with caution. Here are some essential oils to avoid using in a diffuser:

  • Clove oil: Clove oil is a powerful oil that can irritate the skin and respiratory system when used in high concentrations.
  • Wintergreen oil: Wintergreen oil contains high levels of methyl salicylate, which can be toxic when inhaled in large amounts.
  • Anise oil: Anise oil can be irritating to the skin and respiratory system when used in high concentrations.
  • Birch oil: Birch oil contains high levels of methyl salicylate, which can be toxic when inhaled in large amounts.
  • Eucalyptus oil: While eucalyptus oil is safe to use in a diffuser in small amounts, it can be toxic when ingested or used in large amounts.

It’s important to always use essential oils safely and to consult a qualified aromatherapist or healthcare professional if you have any questions or concerns about using essential oils. And always follow the manufacturer’s instructions for your specific diffuser to ensure safe and effective use.
