Three sizes.
One standard of air.

Every Odorsy runs the same cold-air atomiser and the same undiluted oil. The only question is how much space it has to hold.

Cold-AirDiffusion

A precision pump shears pure fragrance oil into a dry micro-mist and lets the room's own air carry it. No water, no heat, no aerosol propellant — so the full molecular profile of the oil reaches the room intact.

The oil itself

Blended in Dubai,
never diluted

Most home diffusers run oil already cut with water or alcohol, then heat it. Two rounds of damage before it reaches the room.

Ours arrives from a Dubai perfume house at full concentration and goes into the machine exactly as blended. That is the whole reason it lasts.

Included with every unit

A perfumer on call,
not a dropdown menu

Buying an Odorsy gets you a person, not just a machine. Someone whose job is working out what your home should smell like and sourcing it.

1

Tell us the room

Size, ceiling height, hard floors or soft, who lives there, what you cannot stand. Ten minutes on a call.

2

Describe a memory

Somewhere you have been that smelled right. You do not need the vocabulary — we will find it.

3

We build and send

We compose it, ship samples, and adjust until it is correct. Your blend stays on file for reordering.

People come to us with things like this

And we go and find it.

Two ways to run it

One room,
or the whole building

Start freestanding. Move to a ducted install whenever you want the entire floor plan covered.

Odorsy freestanding on a console
Freestanding

Plug it in and forget it

Set it down, choose an intensity, done. It scents the open space around it — a main floor, a suite, a showroom.

Ducted into your HVAC

Every register becomes a diffuser

The side outlet ties into your supply plenum. The furnace fan does the distribution, so scent arrives everywhere the ductwork already goes.

Dry mistNothing lands wet

The formula binds the compounds producing the odor rather than covering them, so there is nothing left to resurface in three days.

A dry mist means no damp patches on beds, crates or upholstery, and nothing for a curious animal to lick off a surface.

No tea tree, no pennyroyal, no pine oils — the essential oils commonly identified as risky for cats and dogs are excluded outright.

22 dB, pulsed rather than continuous, with a night mode that dims the indicator to nothing and drops to the lowest setting.

Four steps,

Then it disappears into the room and you stop thinking about it entirely.

1
Press the top cap

It is magnetic. No latch, no tools, no instructions to read.

2
Seat the bottle

It threads into the chamber and locks. Nothing to pour, nothing to spill.

3
Pick an intensity

Start on low. Most rooms need less than people expect.

4
Set a schedule

Or do not. It runs perfectly well on its own.

Questions we hear often

Everything you were
about to ask

Up to 2,000 square feet freestanding, in a normal ceiling height with reasonably open flow. Ducted into your HVAC it covers whatever the ductwork reaches, which in most homes is everything.

No. Most people run it freestanding and never touch their ductwork. The duct outlet is there when you want the whole building covered, and the collar and hose come in the box.

On low, running twelve hours a day, roughly three months. On medium, closer to two. It pulses rather than running constantly, which is why it goes much further than people expect.

Yes. It is a dry mist, so nothing lands wet, and the blends exclude the essential oils commonly flagged as risky for cats and dogs — tea tree, pennyroyal and pine oils among them.

Every blend meets IFRA Category 11, the strictest class, written specifically for products used in the air around children. No phthalates, no parabens, no formaldehyde donors, no propellants.

About 22 dB — quieter than a fridge. It runs in short bursts with long silences, so there is no continuous hum. Night mode drops it further and turns the indicator light off.

You can, but we would rather you did not. The pump is calibrated for a specific viscosity, and thicker third-party oils are the most common cause of a unit needing service.

A perfumer works with you to build a blend for your home — from a description, a memory, or a place you have been. It is included with every unit and your formula stays on file.

Tell us and we will swap it. Scent is personal and choosing from a description is genuinely hard.

Thirty days from delivery. Run it properly, and if it is not right, write to us for a full refund.

We ducted it into the furnace and the whole house changed. Not perfumed — just consistently pleasant, upstairs and down. Three months in and we are still on the first bottle.

Two labradors. My mother-in-law walked in and asked if we had got rid of the dogs. That is the entire review.

The bespoke call was the part I did not expect. I described a hotel in Lisbon badly and they got it almost exactly right on the second sample.

M

Excellent unit. Took me a while to get the intensity right — start lower than you think. Docking a star only because the app took two goes to pair.

Runs in the bedroom all night and I genuinely cannot hear it. Night mode turns the light off completely, which was my worry.

Bought it for the restaurant, ended up buying a second for home. Guests comment every single service.
