Questions people ask

Is a Nēbu diffuser the same technology as Aroma360?
Yes, both use cold-air diffusion. Pressurized air breaks undiluted oil into a dry micro-mist, with no water and no heat.
Can I use Aroma360 oil in a Nēbu diffuser?
Yes. Nēbu diffusers will run other fragrance oils, including Aroma360's. Thick or diluted oils can clog any nebulizer, and damage caused by an unsuitable oil is not covered by our warranty. Nēbu oils are blended for our diffusers and cost about 57% less per milliliter at the 500 ml size.
How much does it cost to run per month?
On the HVAC unit, one 250 ml bottle can last up to 45 days. That's $65 at the one-time price, or less on subscription. Your schedule and intensity setting change this.
