Questions people actually ask

If yours is not here, write to nestcomodapro@gmail.com. A person answers, usually within 24 hours.

Before you buy

Is there a subscription?
No. No subscription, no contract, no minimum term, no cancellation fee. You buy the diffuser once, it is yours, and you refill it if and when you want to. This is the whole reason the brand exists.

Do I have to use your oils in it?
No cartridges, no chip, no lock. It takes any water-free fragrance or essential oil. We think ours are worth coming back for — but that should be your decision, not the machine's.

Which room should I start with?
For the feeling everyone recognises, Nº 01 — The Lobby. For something bright and awake, Nº 07 — Open Window. For an evening in, Nº 21 — The Last Hour. Still unsure? Describe your room to us by email — the light, the season, the hour you are usually in it — and we will tell you honestly, even if the honest answer is to wait.

I want to try several before committing.
That is exactly what The Welcome Kit is: the diffuser plus five small bottles in one box, so you can run a different one each evening and find out which one your house likes.

How much space does one diffuser cover?
A living room, an open kitchen, a large bedroom — up to roughly 1,000 sq ft, depending on ceiling height and airflow. For a small bedroom or an office, run it on the lowest setting or it will be too much.

How long does a bottle last?
An 8 oz bottle runs for months rather than weeks on a normal setting; a 4 oz bottle roughly 90 to 120 days. It depends entirely on intensity and room size — anyone who quotes you an exact number is guessing.

Is it loud?
No. It atomises the oil into a dry mist — no water, no heat, no steam, no gurgling. You hear a soft breath every few seconds and nothing else.

Will it leave residue on my furniture?
No water means no wet mist, so no damp rings and no sticky film. Place it on a flat surface, not on fabric.

Shipping

How fast does it arrive?
1–2 business days to process, 4–10 business days total to your door. Free, always, with no minimum.

Do you ship outside the US?
Not yet. We ship within the United States only for now. Tell us where you are and we will keep you on the list.

Why did my order arrive in two boxes?
Our diffusers and our oils are packed at different fulfillment centers. If you ordered both, they travel separately and can land a day or two apart. Nothing is missing.

My tracking has not moved.
A label is created before the parcel is scanned, so it is normal for the first 48 hours. If it has not moved after 10 business days, write to us — we reship or refund, your choice. We chase the carrier, not you.

If it is not right

Can I return it?
Anything unopened goes back within 30 days for a full refund. A diffuser can be returned within 30 days if it is in working condition — write to us first and we will send instructions.

What about an opened bottle of oil?
An opened bottle cannot be resold, so it is not refundable — which is precisely why we would rather you ask us first than guess. If a bottle arrives faulty, leaking, or clearly not the scent described on the page, that is on us and we replace it.

It arrived damaged.
Send a photo within 7 days. We replace it. Do not ship anything back.

Is the diffuser guaranteed?
Yes — 12 months against manufacturing defects. If it stops working through no fault of yours, we replace it.

Living with it

Is it safe around children and pets?
Keep the unit and the bottles out of reach of children and animals, never let anyone drink the oil, and ventilate the room from time to time. Some fragrance and essential oil compounds — citrus and conifers in particular — are not suitable around cats, birds and small pets. If you have animals in the house, check with your vet before running any diffuser regularly.

Is this a health product?
No. Our oils are home fragrance. They do not treat, cure or prevent anything, and they are not for skin or ingestion. They are there to make a room feel like somewhere.

How do I clean it?
When you change rooms, let the previous scent run out before refilling, or run a little unscented carrier through it for a minute. Wipe the outside with a dry cloth.

Payment and privacy

Is checkout secure?
Yes. Payment is handled by our payment provider over an encrypted connection. We never see or store your full card details.

Do you sell my data?
No. Never have, never will. See our privacy policy for the full detail.
