A practical FAQ on Scent Tower fragrance oil sizes, how long a 30 ml bottle lasts, and when a larger refill makes sense for your diffuser routine.
Quick answer
For a single Scent Tower diffuser used a few hours a day, a 30 ml fragrance oil is the simplest starting point and keeps the oil fresh. Choose a larger refill only if you run the diffuser daily in a busy room or want to avoid reordering often. Match the oil to the diffuser it was made for, and store any extra away from heat and direct sun.
What is Scent Tower fragrance oil made for?
Scent Tower fragrance oil is formulated specifically for use with the Scent Tower Electric Fragrance Diffuser. That matters because diffuser oils are not interchangeable with reed diffuser refills, lamp oils, or candle melts. Using the wrong liquid can affect how the scent throws, how quickly the reservoir empties, and whether the device performs as intended. If you already own the Scent Tower diffuser, the 30 ml oil is the matching consumable.
30 ml vs 120 ml: which size should you buy?
The honest answer depends on how often you diffuse. A 30 ml bottle suits one diffuser used occasionally, a bedroom, or someone testing a new scent before committing to a larger bottle. A 120 ml refill suits a diffuser that runs most days, an open-plan living area, or a household that rotates the same favorite scent. There is no universal run-time number because diffusers vary in output and timers, and the catalog does not list a burn rate for these oils. Treat the size choice as a question of frequency and storage, not a fixed day count.
- Buy 30 ml if you are new to the scent or use the diffuser a few times a week.
- Buy 120 ml if the diffuser runs daily and you already know you love the fragrance.
- Buy 30 ml in two scents if you like variety and want to avoid a large bottle going stale.
How long does fragrance oil last in the bottle?
Unopened fragrance oil generally keeps longer than an opened bottle, and heat, light, and air are the main things that dull a scent over time. Keep the cap tight, store the bottle upright in a cool dark cabinet, and avoid leaving it on a sunny windowsill. If a bottle has been open for many months and smells weaker, it may simply have lost top notes rather than gone bad. The catalog does not publish a specific shelf life for these oils, so use your nose and the storage conditions as your guide.
Can you switch scents in the same Scent Tower diffuser?
Yes, but empty the reservoir before adding a different oil. Mixing two fragrances rarely gives you a clean version of either one. If you want to move from a floral to a woody scent, run the diffuser until the old oil is used up, wipe the reservoir as the device instructions allow, then add the new oil. Keep partial bottles labeled so you can return to a scent later without guessing.
Scent Tower oil FAQ
- Is Scent Tower fragrance oil the same as reed diffuser oil?
- No. Scent Tower fragrance oil is made for the Scent Tower Electric Fragrance Diffuser. Reed diffuser refills are designed for passive reed systems, and swapping them can change how the scent performs. Use the oil that matches your diffuser type.
- How long does a 30 ml bottle last?
- There is no published run-time for these oils because diffusion rate depends on your device settings and how many hours you run it. A 30 ml bottle is best for occasional use or trying a scent. Track your first bottle for two weeks to learn your own usage rate.
- Should I buy the 120 ml refill right away?
- Only if you already know the scent works in your space and you diffuse often. Otherwise start with 30 ml, live with it for a week, then size up. Start small, then commit to the larger refill once the scent proves itself.
- Where should I store extra oil?
- Keep bottles capped, upright, and away from heat and direct sunlight. A cool cabinet protects the fragrance better than a bathroom shelf or windowsill. Store oil like you would store coffee: dark, cool, and sealed.
