Frequently Asked Questions
Scent diffuser questions, answered.
The questions buyers actually ask before they hit "buy."
What is a nebulizing diffuser?
A nebulizing diffuser uses pressurized air to break pure essential oil into ultra-fine nano-particles - no water, no heat, no dilution. The result is a stronger, purer scent that covers a much larger area than ultrasonic diffusers. Every Nēbu diffuser uses this cold-air nebulizing technology.
Which Nēbu diffuser is right for me?
How long does one bottle of fragrance oil last?
Assuming a 100ml bottle: the NL50 (10 ml capacity) lasts about 12 months. The NL100, NL200, and NL300 (100 ml) last 2-4 months at medium intensity. The HVAC unit (150 ml) lasts about 20 days at medium intensity with daily use.
Are Nēbu diffusers safe around pets and children?
Yes. All Nēbu fragrance oils are phthalate-free, paraben-free, and free of known harmful chemicals. Cold-air nebulizing uses pressurized air instead of heat or water, so there are no hot surfaces or misted moisture.
Can I control Nēbu diffusers from my phone?
Yes - every Nēbu diffuser except the NL50 has Bluetooth connectivity and works with the Nēbu app. From the app you can set up to 5 weekly schedules, choose intensity from 4-20 levels (depending on model), and turn the unit on/off remotely.
What's the return policy?
180-day happiness guarantee on every Nēbu diffuser. Try it in your home for up to 180 days - if it doesn't work for your space, we'll refund you in full. Free U.S. returns, no restocking fees.
Do bundles really save money?
Yes - in some cases the bundle is actually cheaper than the diffuser alone. Most bundles save 40-54% compared to buying separately.

The Collection
About Luxury Scent Diffusers
A Nēbu cold air diffuser scents a room without water, heat, or residue. Rather than misting fragrance into humidity, the pump atomises pure oil into a dry nebulised cloud, so the scent that reaches the room is the scent that was blended: nothing diluted, nothing cooked off. It is the method used to scent hotel lobbies, and it is why a luxury scent diffuser can hold a room evenly for hours on a few millilitres of oil.
Choosing between the models
Which cold air diffuser you want comes down to the size of the space. The NL50 is cordless and palm-sized, made for a bathroom, a closet, a car or a desk. The NL100 is the everyday Bluetooth waterless diffuser for a bedroom or office up to roughly 400 square feet. The NL200 steps up to larger open rooms and is where most people land for a living room. The NL250 covers big open-plan spaces, and the NL300 is the wireless Bluetooth flagship, with app scheduling and intensity control.
Two models exist for whole-property scenting. The NL360 mounts on a wall and speaks Zigbee for anyone running a smart home, and the whole-house HVAC scent diffuser connects to existing ductwork so a single unit scents an entire building.
One oil range across every model
Every diffuser here runs on the same Nēbu fragrance oils, so a scent you like in one room scales to the whole house without changing what it smells like. If you want the same profile on bedding and towels, most of the range is also made as room and linen sprays.
