The mist is finer than a micron. It drifts into sofa fabric, rugs, curtains and bedding — the same places the odour soaked in — and stays dry the whole way.

Quick answers
How much space does one unit cover?
M1 covers up to 3,200 sq ft, M2 up to 10,700 and M3 up to 13,000.
How long does one 120 ml bottle last?
Roughly a month of daily use in a normal home setting. Larger spaces or a higher intensity will use it faster.
Does it use water or heat?
Neither. Cold-air atomisation breaks pure oil into a dry micro-mist, so there is no steam, no dilution and no damp residue on furniture.
Can I run it through my HVAC?
Yes — all three models are HVAC-ready and mount to a duct so one unit scents the whole floor. They also work standalone on a shelf.
What about pets and children?
The mist is dry and the oils are IFRA-compliant for home use. Keep the bottles themselves out of reach, as you would with any concentrated oil.
Can I change or cancel refills?
Any time. Skip a delivery, change the interval or cancel from your account — nothing is locked in.

Come home to a house that already smells right.
Not a candle by the door. Every room, every floor, from the moment you walk in — and nothing you have to remember to light, refill or switch on.
- After workOpen the door to the lobby of a hotel you loved, not to dinner from yesterday.
- With petsThe dog stays. The dog smell does not. Odor is neutralised, not perfumed over.
- When guests arriveOne tap lifts the whole floor half an hour before the doorbell.
Softer at night. Stronger for guests.
Scent is a dial, not a switch. Three levels, a schedule that follows your week, and it holds whatever you set — from the app, the remote, or the button on top.
LowBedrooms, overnight. Noticed when you walk in, forgotten a minute later.
MedThe everyday setting for most homes. Where to start.
HighOpen-plan floors, after cooking, before people arrive.
- ScheduleSet 7:00 am to 10:30 pm on weekdays and it runs itself. Weekends can be different.
- Turn it upOne tap lifts the whole floor for thirty minutes, then drops back on its own.
- Turn it downNight mode goes to Low and switches the amber light off completely.
Odorsy pulses rather than running continuously, so a lower setting goes further than you expect. Start on Med.
Build your Odorsy
The dog stays.
The dog smell doesn't.
Pet odour is molecules sitting in your sofa, your rugs and your air. A candle adds more on top. Odorsy neutralises the ones already there — then scents the clean air that's left.
NeutralisedOdour molecules are bound, not masked
Dry mistNothing lands wet, nothing to lick off
Pet-safeNo tea tree, pennyroyal or pine oils
How it removes odour, not just covers it
Every Odorsy blend carries a neutralising base under the fragrance. It bonds to the compounds that make dog smell like dog, so they stop registering to your nose.
With nothing competing, Low is enough. The house smells the same at 6 pm as it did at 8 am, whoever has been on the couch.

Pure oil. A reservoir that lasts months.
Every bottle is fragrance oil and nothing else — no water, no alcohol, no carrier. Composed with top, heart and base notes so it holds in open air for hours, then metered out in pulses so a little goes a very long way.

Cold air. Pure oil.
Nothing else in the room.
Most diffusers heat oil, or float it on water. Odorsy pushes filtered air through the oil at high velocity and shears it into a dry micro-mist — fine enough to stay airborne, dry enough to touch nothing.

Everything you were
about to ask
M1 covers up to 3,200 square feet, M2 up to 10,700 and M3 up to 13,000 — freestanding, at a normal ceiling height with reasonably open flow. Ducted into your HVAC, it covers whatever the ductwork reaches.
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.
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.
What people actually say
4.8253 reviews
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.
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.
