Love that Nēbu uses the same oil for all of their diffusers not having to buy all different kinds. Working great for doing my living room and dining room which is open beautiful scent,

Susan F Verified Buyer

I love my new diffuser - My husband came home and immediately said how great the smell was 😃 - Great deal compared to the one I was about to buy at Aroma360. Thank you Nebu!

Safiya M Verified Buyer

I love having the ability to schedule the device. I have 2 now. You have to pick the right scent to fit your style. Oils are stronger than others I’ve tried and carry throughout the house.

JD Verified Buyer

I love this unit! I've purchased some of the wall plug-in units from Nebu and decided to upgrade to this machine. I'm truly loving it!

Kymry P Verified Buyer

My friend had one of the Nebu bluetooth diffusers in her house and the scent was amazing. I had to have one and I am so glad I bought one. It works well and the app is easy to use.

Product Description

Elevate your sensory environment with Nēbu. Our state-of-the-art nebulizing diffuser is more than just an aroma dispenser; it's a statement of luxury. Whether connected to your HVAC system to drench your entire home in captivating aromas or stationed independently to invigorate large open spaces, it promises a bespoke scent experience. Control, customize, and connect - all through our seamless Bluetooth Nēbu app. Dive into a world where fragrance meets technology. Choose from 20 programmed scent levels or create your own experience with custom scheduling.

This versatile nebulizing fragrance scent diffuser is ideal for use in central air conditioning units or large open (commercial) areas. It comes with two setup options:

HVAC Installation (Up to 3000 square feet) (includes fittings and hose) - Using this option, the hose will deliver the scent to a small hole you'll create in your ductwork or plenum. The scent will be pushed throughout your ductwork and into all rooms connected to your air conditioning system. Please note a standard 110v plug is required for the diffuser so ensure you have a plug nearby for a tidy setup.
Large Room Diffusing (Up to 1500 square feet) - This advanced scent diffuser can really scent a large room quickly. Some people and businesses use this diffuser out in the open (easy installation on wall or floor) to scent a large area. Because the fragrance is very strong near the diffuser, it is recommended to ensure this is done in a large room, keeping the diffuser near airflows and away from groups of people.

Ensure Nebulizing Success

Start by plugging in your diffuser, syncing it to the Nebu app via Bluetooth, and adding your favorite fragrance oil — setup takes just minutes, and your space transforms instantly.

Pro tip 1

Install the diffuser in a spacious area near airflow (like an air vent) to ensure even scent distribution or directly to your HVAC system.

Pro tip 2

Begin with the lowest setting - this diffuser is powerful. Gradually increase the intensity to match your space and preference.

Pro tip 3

Use genuine Nēbu fragrance oils as they are specially blended with the exact viscosity for our diffusers, ensuring clean, consistent diffusion.
