About this bundle.

YOUR SCENTS, YOUR WHOLE HOME: BUILD YOUR HOTEL-LUXURY BUNDLE

Why settle for a set lineup when you can curate your own? This bundle pairs the Whole House HVAC diffuser with the freedom to choose any three of our signature fragrances in generous 250ml bottles. Pick the urban allure of New York, the exotic charm of Dubai, or any trio that speaks to you, and let your entire home tell the story. And because each 250ml bottle lasts roughly six to eight weeks, your custom trio keeps every room smelling like a luxury hotel for well over three months on a single bundle.

WHOLE HOUSE HVAC DIFFUSER | One Unit, Every Room

Instead of scenting one room at a time, the Whole House diffuser uses the air your home is already moving. It installs next to your air handler, with the included hose and fittings feeding fragrance into your ductwork, so every vent in the house delivers a clean, even scent. Most installations take under an hour for a homeowner comfortable with basic HVAC access, and it runs from a standard 110V outlet. Inside, cold-air atomization breaks pure fragrance oil into nano-fine particles. No water, no heat, no aerosol propellant, just the full complexity of every Nēbu scent carried uniformly through up to 3,000 square feet. With the companion Bluetooth App, you fine-tune across 20 intensity levels and set up to five weekly schedules, so your home greets you the way you want, room after room.

CHOOSE YOUR FRAGRANCE TRIO | Three Full-Size 250ml Bottles

Use the drop-down menus to select your three favorite Nēbu fragrances, each in a generous 250ml bottle. Stay loyal to one signature mood across the house, or rotate three completely different worlds through the seasons, the choice is entirely yours. Swap them whenever inspiration strikes, and with the Bluetooth App you can dial in intensity and build weekly schedules so your whole home always smells exactly the way you want.

How it works

Cold-air nebulizing, no water, no heat.

Pressurized air turns pure fragrance oil into nano-particles that stay suspended in the air - so the scent spreads further and lasts longer than a mist.

01

Screw in the bottle

Any Nēbu 15ml or 100ml oil threads straight in. No pouring, no water to top up.

02

Set it from your phone

Pick the intensity and the hours it should run. It only works when you want it to.

03

Nothing is diluted

Pure oil atomized with air - no heat to alter the fragrance, no residue on furniture.

04

It lasts

A bottle goes much further than in an ultrasonic diffuser, because nothing is wasted in water.

Good to know

Questions about this HVAC kit.

What is an HVAC scent diffuser?
An HVAC scent diffuser is a fragrance unit that connects to your home's central air system (the return air duct) so your existing HVAC distributes scented air through every vent. Instead of one diffuser per room, a single HVAC unit scents your whole home at consistent intensity. The Nēbu HVAC diffuser uses cold-air nebulizing technology - no water, no heat, just pressurized air that atomizes pure essential oil into nano-particles.
How does an HVAC scent diffuser work?
A small hose runs from the diffuser into your HVAC return duct. When the unit is on, it pressurizes pure fragrance oil into ultra-fine nano-particles and releases them into the airstream. Your HVAC fan pulls that scented air across the entire system and pushes it out through every vent in the house. You control intensity, schedule, and on/off via Bluetooth from your phone.
Will this work with my home's HVAC system?
If you have central forced-air (the most common system in U.S. homes - warm or cold air delivered through vents in each room), yes. The Nēbu HVAC diffuser comes with hose fittings that attach to your return duct. Installation typically takes 20-30 minutes and doesn't require an HVAC technician. The unit is fully reversible and leaves no trace if removed.
What if I don't have central HVAC - can I still use it?
Yes. The HVAC unit is the only Nēbu diffuser that also works as a standalone unit covering up to 1,500 sq ft. Wall-mount it or place it on the floor in any open-plan space and it'll scent the whole area on its own - the largest coverage of any standalone Nēbu diffuser. Smaller rooms (under 800 sq ft) can use the NL200 or NL100 instead.
How long does one bottle of fragrance oil last?
About 45 days at medium intensity with daily use. Heavy use or higher intensity levels (like 15-20 of 20) will use oil faster; low or scheduled use can extend a bottle to 60+ days. The HVAC unit holds 150 ml - bigger than the NL100 and NL200 (both 100 ml) - so you refill less often.
Is it safe around pets and children?
Yes. All Nēbu fragrance oils are phthalate-free, paraben-free, and free of known harmful chemicals. Because cold-air nebulizing uses pressurized air instead of heat or water, there are no hot surfaces or misted moisture that could affect small animals or young kids. The fragrance is safe to breathe at recommended scent levels.
Will the diffuser damage my HVAC system?
No. The hose attaches non-invasively to your return duct and the oil is released as nano-particles that don't condense, pool, or coat surfaces. Pure essential oils with no water means no humidity is added to your ductwork. Thousands of homeowners and short-term rentals use HVAC scent diffusers safely for years.
How is this different from an ultrasonic diffuser?
Ultrasonic diffusers mix essential oil with water and emit visible mist - this dilutes the fragrance, only covers a single small room, and can leave mineral residue on surfaces. The Nēbu HVAC diffuser uses pressurized air (no water) to atomize pure oil into nano-particles - dramatically larger coverage, pure fragrance with no dilution, no residue, no water tank to refill, no risk of mold.
Can I schedule when it runs?
Yes. The Nēbu Bluetooth app lets you set up to 5 weekly schedules (e.g. weekdays 7-10am and 5-9pm, weekends all day) at any of 20 intensity levels. Set it once, forget it - the diffuser runs the way you live.
How much does an HVAC scent diffuser cost?
Our HVAC bundles (diffuser + 3 fragrance bottles) are currently $425 (regular $695), and the diffuser alone is $299. For comparison, commercial HVAC scent systems often run $800-$2,000+ - so Nēbu delivers the same whole-home coverage at residential pricing. See full pricing →
What's the return policy?
180-day happiness guarantee. Try the HVAC scent diffuser 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.
