How many essential oils drops to add to aroma diffuser

How many drops of oil should you add to your aroma diffuser?

Aroma diffuser’s are a fun way to fragrance your home. But I often get asked how to clean them and the most common question I get asked, is how many drops of essential oil should I add to the water? So here’s my guide on how many drops you can use in your aroma diffuser.

Filling your aroma diffuser

Use clean, room temperature tap water. Most aroma diffusers come with a plastic jug, so use yours to fill water as it avoids the need to carry the diffuser to the sink. Make sure the water level does not exceed the water mark.

Add 5 drops of essential oils. You can add more oil for a stronger scent. Experiment with the amount of oil you use and find what works best for you.

Make sure to unplug your aroma diffuser prior to cleaning. Remember to remove any excess water from the water tank, pour from the rear of the diffuser to avoid spilling on the operating buttons.

Clean the inside of the water tank and the outside of the diffuser with a dry kitchen towel. This should remove any oil residue. Avoid using any harsh cleaners on your diffuser.

Deep clean once a month if used regularly

Essential oil residue, can build up over time if your aroma diffuser is not cleaned properly. If you use your unit every day, then running a cleaning cycle monthly is a good idea. Here’s how:

Fill your diffuser half way with clean water.
Add 10 drops of white vinegar.
Let the diffuser run for about 5 minutes to allow the mixture to disperse throughout the unit and clean it.
Drain the diffuser completely.
Using a cotton swab dipped in vinegar, clean the tight spots and corners of the diffuser.
Rinse with clean water.
Use a dry cloth to wipe the diffuser and dry it thoroughly.

Why use an aroma diffuser to get benefits from essential oils?

The sense of smell can elicit powerful physiologic, mental, and emotional responses. Essential oils are quickly absorbed by the smell receptors, which have a direct link to the limbic system by way of the olfactory nerve. The limbic system is part of the brain that supports a variety of functions including smell, emotions, behaviour, and memory. Some essential oils induce uplifting or invigorating effects, while others are more calming. Diffusion is the simplest method for using essential oils aromatically.
