Diffusers are popular tools for those who want to have a relaxing and pleasant ambience in their homes, offices, or other spaces. Using essential oils, diffusers can provide numerous benefits such as stress relief, improved mood, and better sleep quality. However, many people wonder about the right amount of oil to put in diffusers to achieve the perfect aroma ratio. This comprehensive guide will help you learn everything you need to know about how much oil to put in diffuser and how to get the most out of it.

Understanding Diffusers and Essential Oils

Before we dive into the right amount of oil to put in a diffuser, let’s first understand the basics of how diffusers and essential oils work together. A diffuser is a device that disperses essential oils into the air, allowing you to enjoy the benefits of aromatherapy. Essential oils are concentrated plant extracts that are used for their therapeutic properties.

Types of Diffusers

  • Nebulizing Diffusers: They use pressurized air to create a fine mist of essential oils.
  • They use ultrasonic vibrations to break the essential oils into tiny particles.
  • Evaporative Diffusers: They use a fan to blow air through a pad or filter containing essential oils.
  • Heat Diffusers: They use heat to evaporate the essential oils into the air. Examples include candle diffusers, electric heat diffusers, and aroma lamps.

Factors that Affect Diffuser Performance

  • Room size
  • Humidity levels
  • The number of people occupying the space
  • The strength and quality of the essential oils used
  • The type of diffuser being used
  • The amount of oil used

The Perfect Aroma Ratio: How Much Oil to Put in Diffuser

The right amount of oil to put in a diffuser depends on several factors such as the size of the room, the type of diffuser, and the strength of the essential oils. As a general rule of thumb, use the following ratios:

  • For a small space (such as a bedroom or bathroom), use 3-5 drops of essential oil per 100ml of water.
  • For a medium-sized room (such as a living room or office), use 5-8 drops of essential oil per 200ml of water.
  • For a large room (such as a conference room or studio), use 8-10 drops of essential oil per 300ml of water.

It’s essential to note that some oils are stronger than others, and you may need to adjust the ratio accordingly. Experiment with different oils and ratios to see what works best for you.

Other Tips for Using Diffusers

Use High-Quality Essential Oils

Choosing high-quality essential oils is crucial for getting the most out of your diffuser. Look for oils that are 100% pure and extracted through a steam distillation or cold-pressing method. Quality oils are more potent and offer more significant therapeutic benefits than synthetic oils.

Clean Your Diffuser Regularly

Keeping your diffuser clean is essential for its long-term performance. Over time, essential oils can build up inside the diffuser and clog it. To clean your diffuser, simply wipe it down with a cloth after each use and do a thorough cleaning every week.

Do Not Overuse Diffusers

While using essential oils in diffusers can have many benefits, it’s crucial not to overuse them. Excessive use of essential oils can lead to respiratory problems, headaches, and other health issues. Limit your diffuser use to 30-60 minutes at a time, and use it no more than three times a day.


Using essential oils in diffusers is an excellent way to enjoy the benefits of aromatherapy. By understanding the right amount of oil to put in diffuser and following other tips for using your diffuser, you can create a relaxing, refreshing, and healthy atmosphere in your space.
