Accurately setting the fragrance intensity of a diffuser: the basics
Accurately setting the fragrance intensity of a diffuser means adjusting the misted oil per hour to the room and the desired effect. At Elemi, it is all about the right fragrance at the right time.
An aroma diffuser is a device that converts fragrance oil into a fine mist without heating. European Chemicals Agency, safe use of fragrances
The most common complaint: it is always either too strong, or you smell nothing.
How many drops of essential oil in a diffuser: dosage per technology
The dosage depends on the technology, not the room. Cold-air nebulization works with pure oil and no water.
- Cold-air nebulization: no water, only pure fragrance oil
With cold-air nebulization, the drop is not your unit, but milliliters per hour. A nebulizer of 1 ml per hour smells very different after two hours than after ten minutes.
Setting a diffuser per room: adjusting the intensity to square meters
The room size determines your starting point, not your endpoint. Calculate the volume in cubic meters: a ceiling of 3 meters almost doubles the volume of a room of 20 m².
| Room | Volume | Starting level | Fan speed |
|---|---|---|---|
| Bedroom | up to 30 m³ | low setting | low |
| Small office | 30-60 m³ | low setting | medium |
| Living room | 60-150 m³ | medium setting | medium |
| Lobby or store | 150-500 m³ | high setting | high |
| Large hall | 500 m³ and more | high setting | high |
This is how it works step by step:
- Calculate the volume: length × width × height
- Start on the lowest setting, even in a large room
- Wait 30 minutes and increase by one level at a time
- Note what works, per room and per fragrance
Our Diffuser Elemi NANO (+ app) covers 300 m³ and is suitable for smaller rooms. For larger rooms up to 500 m³, the Diffuser Elemi MAX (+ app) and the Diffuser Elemi PRO (+app) are suitable. The Diffuser Elemi display covers 800 m³ and is intended for waiting rooms, toilets, and reception areas.
Frequently Asked Questions
How do I accurately set the fragrance intensity of a diffuser?
Start on the lowest setting and increase step by step until you reach the desired fragrance strength. Use the app control of your diffuser to precisely adjust the intensity, fan speed, and timer to the room. Test for 30 minutes before increasing further, so the fragrance can spread evenly.
Why do I barely smell my diffuser or is it too strong?
A too weak fragrance often indicates an intensity setting that is too low or a room that is larger than the range of your diffuser. Too strong fragrance is usually caused by a setting that is too high or a room that is too small. Adjust the fan speed and the intensity level to the square meters of the room.
How do I adjust the fragrance strength to the size of the room?
Choose a diffuser with sufficient range in square meters. For a small office or bedroom, a low setting is sufficient, while a lobby or store requires a higher setting and longer distribution moments. Adjust the timer to the active hours of the room and check regularly if the fragrance is still consistent.
A diffuser that is never set correctly costs you oil every month without anyone noticing the difference. At Elemi, we work with ten fragrances and complete control over intensity and timing, so that every room gets its own atmosphere. With app control, adjustable levels, and a timer function, you adjust everything to the moment. Discover the diffusers and set up your first room.
