Which Scentia Bottle Fits Your Diffuser?
You almost never need a new diffuser to try Scentia oils — just the right replacement bottle. Here's how to find yours.
Updated September 2026
At a Glance
Two Bottles Cover Almost Everything
Style 1 — Universal
120ml pour-in bottle. Fits Scentiment, most tower diffusers, and general market brands on Amazon and Walmart.
Style 2 — Fitted
120ml bottle shaped for Scentia Max, Homedics, and Airscent, among other popular diffusers.
One Exception
Hotel Collection's Pro Pod bottle is a locked system. Everything else on this page is an open pour-in reservoir.
A 10-Second Check for Your Current Bottle
Before ordering, look at the bottle currently in your diffuser. Almost every diffuser on the market uses an open system: the bottle has a peelable seal under the cap, you peel it, pour the oil in, and you're done. If that's what you're looking at, any diffuser sold under a generic tower-diffuser design, Scentiment, or an Aroma360 Kube, a universal replacement bottle will work.
There's one real exception. If your bottle has a tube running down inside it connected to the cap, and there's no peelable seal to open, that's a locked cartridge design — the version Hotel Collection calls a Pro Pod. That system is built to keep you buying oil from Hotel Collection specifically. More on that below.
Style 1 — For Scentiment and Most Market Diffusers
Style 1 is a universal 120ml pour-in bottle. It's the right pick if you own a Scentiment diffuser, a generic tower-style diffuser, or one of the many similar cold-air diffusers sold on Amazon or Walmart under smaller brand names. These all use the same basic open-reservoir design, and Style 1 is built to fit that shape.
If you own an Aroma360 diffuser with the Regular bottle option rather than a Pro Pod, or the newer Aroma360 Kube, Style 1 is also your bottle — both use an open pour-in system with no lock.
Shop Style 1 Bottle →Style 2 — For Scentia Max, Homedics, and Airscent
Style 2 is also a 120ml bottle, but shaped specifically to fit Scentia Max, along with popular brands like Homedics and Airscent. If you already own a Scentia Max and just need a spare or replacement bottle, or you're running a Homedics or Airscent diffuser and want to try a Scentia fragrance oil, this is the one to order.

Hotel Collection's Pro Pod Is a Locked System
When you buy oil from Hotel Collection, you choose between a Regular bottle and a Pro Pod bottle at checkout. Pro Pod is the one to watch for — it has a tube built into the cap that screws directly into the machine, and no peelable seal, which makes it very difficult to refill with anything else. That's by design: it keeps Pro Pod customers buying oil from Hotel Collection specifically.
If that's the bottle in your machine, we're not going to pretend there's an easy workaround — there isn't one we'd recommend. If you bought the Regular bottle option instead, or you're due for your next refill and want to switch, Style 1 above is the one to order.
Frequently Asked Questions
Will Scentia oil work in my existing diffuser?
In most cases, yes. Scentia oils are pure, undiluted fragrance oils built for cold-air nebulizing systems generally, not a proprietary cartridge — so they work in most tower diffusers and market brands. The exception is diffusers using a locked cartridge system, like Hotel Collection's Pro Pod bottles.
What's the difference between Style 1 and Style 2 replacement bottles?
Style 1 is a universal 120ml pour-in bottle compatible with Scentiment diffusers, most tower-style diffusers, and general market brands sold on Amazon and Walmart. Style 2 is also 120ml and is fitted for Scentia Max, Homedics, and Airscent, among other popular diffusers.
How do I know if my diffuser has a locked cartridge system?
Check the bottle: if you can peel open a seal and pour the oil out, you have an open system and a universal replacement bottle will work. If there's a tube running down inside the bottle and no peelable seal, that's a locked cartridge design, like Hotel Collection's Pro Pod.
Does Scentia oil work in a Hotel Collection Pro Pod bottle?
Not easily. The Pro Pod bottle has no peelable seal and a tube built into the cap that screws directly into the machine, which is designed to keep you buying Hotel Collection's own Pro Pod oil. If you bought the Regular bottle option instead of Pro Pod, Scentia's Style 1 bottle will work as an open pour-in replacement.
Will Scentia oil work in an Aroma360 Kube or a Scentiment diffuser?
Yes. Neither uses a proprietary locked cartridge — the Aroma360 Kube fills freely, and Scentiment diffusers use an open reservoir. Scentia's Style 1 bottle is compatible with both.
