Founder Diaries · Diffuser Care & Usage
What precautions should I take? Run it on a low output in a ventilated room, place the diffuser out of pets' reach, never confine a pet with it, and stop if your pet shows any discomfort. Cats can be especially sensitive.
When should I ask my vet? If your pet has asthma or breathing issues, is very young, old or unwell, or if you are unsure - check with your vet. This is general information, not veterinary advice.

Is ultrasonic diffuser fragrance safe for pets?
This is a question I always want people to ask, because pets experience scent far more intensely than we do. The honest, careful answer: home fragrance can be used around pets if you are gentle and thoughtful, but their comfort and safety come first. Here is how to do it responsibly - and when to ask your vet.

Is diffuser fragrance safe around pets?

Keep it subtle, ventilated, and let pets leave the room freely.What precautions should I take?

The short answer
Pets smell far more intensely than us. Their comfort comes first - keep any fragrance gentle and let them leave freely.
Gentle, ventilated, escapable. Low output, fresh air, diffuser out of reach, never confine a pet with it.
Cats can be more sensitive. This is not reed diffuser oil - keep the bottle out of reach and watch your pet.
Ask your vet if unsure. General information, not veterinary advice. Hotel Collection is water-based.

Straight answer
Is ultrasonic diffuser fragrance safe to use around pets?
The careful, honest answer: used gently and thoughtfully, home fragrance can be run around pets in many households - but animals smell far more intensely than we do, some are more sensitive than others (cats especially), and their comfort and safety come first. Keep it subtle, in a ventilated room, with the diffuser out of reach, and never confine a pet in a room with it - let them leave freely. Stop immediately if your pet shows any discomfort. If your pet has breathing issues, is very young, old or unwell, or you are unsure, check with your vet. The SOSA Hotel Collection is water-based, IFRA-standard and phthalate-free, but this is general information, not veterinary advice - your vet knows your animal best.
In one line: used gently and thoughtfully - low output, ventilated, diffuser out of reach, pets free to leave - home fragrance can be run around many pets. Cats are especially sensitive. Stop if your pet is bothered, and ask your vet if unsure. General information, not veterinary advice.
Pet-mindful: the SOSA Hotel Collection is water-based and phthalate-free - run it gently. Ask your vet if unsure.

Why pets need extra care
A dog's sense of smell is many times keener than ours, and a cat's metabolism processes substances differently from a human's. So a scent that is barely-there to you can be much more present to them, and what is fine for us is not automatically fine for them. That is why I always lead with caution here, not sales.
Care, gentleness and watching your pet are the whole approach.
The pet-care brief
Around pets, use home fragrance gently - low output, ventilated, diffuser out of reach, and never confine a pet with it. Watch your pet and stop if it is bothered. This is not reed diffuser oil - SOSA's fragrance is water-based and phthalate-free. This is general information, not veterinary advice; consult your vet for your specific animal.
Cats can be more sensitive than dogs, so be especially cautious in a cat household - keep fragrance very light and always give them a fragrance-free room to retreat to.
Let me clear up two things
✕
"If it is safe for me it is safe for my pet." Not necessarily - pets smell more intensely and metabolise differently. Use extra caution and watch your animal.
✕
"Pets get used to any scent." Some tolerate gentle fragrance; others are genuinely bothered. Let them leave the room and respect their response.
How to use it responsibly
Simple, pet-first habits.
1
Gentle and ventilated
Low output, fresh air
Run it on the lowest pleasant setting in a well-ventilated room, so the scent is faint. Never run it strong around animals.
2
Let pets leave
Never confine them
Keep the door open so your pet can move to a fragrance-free room. Never shut a pet in a room with a running diffuser.
3
Out of reach, and watch them
Safety and attention
Place the diffuser and the fragrance bottle out of your pet's reach, and watch for any sneezing, drooling, or restlessness - ease off or stop if you see it.
The honest steer
With pets, the rule is simple: their comfort first, fragrance second.
Gentle, ventilated, escapable, and watched - and check with your vet if you are ever unsure.
Pet-safe use
Responsible habits around pets
| Habit | Why | Note |
|---|---|---|
| Low output | Pets smell intensely | Keep it faint |
| Ventilated, door open | Let them leave | Never confine |
| Out of reach | Safety | Bottle and diffuser |
| Watch your pet | Respect their response | Stop if bothered |
So around pets, keep fragrance gentle, ventilated and escapable, watch your animal, and put their comfort first. A diffuser scents a room for ambience; it does not purify the air. For any specific concern - breathing issues, a young, old or unwell pet - consult your vet. This is general information, not veterinary advice.

A note from Sonal
I trained as a perfumer at ISIPCA in Versailles, and the one thing every great hotel taught me is that scent is the first thing you notice and the last thing you forget. I wanted to bottle that feeling for the home.
So the Hotel Collection is seven water-based diffuser fragrances, each my own interpretation of the style a famous hotel is known for - composed in our own lab, made to run cleanly through a SOSA ultrasonic diffuser. Please use the SOSA diffuser fragrance only; raw essential or carrier oils are thick and can clog the misting plate.
To be clear: these are inspired interpretations, not the hotels' actual proprietary scents. SOSA is not affiliated with or endorsed by the hotels named - the names just describe the scent style. I would rather you knew exactly what you are buying: a perfumer's take on that hushed, expensive calm, at a fair price.
