Frequently Asked Questions
How many drops should I use for a long-run diffuser?
For quiet, long-run ultrasonic diffusers start with 2–4 drops of concentrated oil or 4–6 drops of lighter single-note oils in the tank. Reduce if the aroma becomes too strong; denser oils (resins, balsams) often need fewer drops.
Are these oils safe to use around pets or children?
Some essential oils can affect pets or sensitive people. Choose gentle, well-diluted options and ventilate the room. Research specific oils for pet safety and consult a veterinarian if unsure before long-run diffusion.
Will these oils damage my ultrasonic diffuser?
Aroma oils and essential oils won’t usually harm a quality ultrasonic diffuser when used as directed, but avoid adding undiluted resinous oils in very large amounts and clean the reservoir regularly to prevent buildup. Follow your diffuser maker’s cleaning instructions.
