A car aroma diffuser gives you more control over cabin fragrance than a one-setting freshener. The useful differences are how it starts, how you adjust it, how much oil it holds and whether it can move between the car and another space. For LEAFI, those details vary across X-AIR, Y-AIR and Z-AIR.
All three are rechargeable and waterless. They use pure diffuser oil directly and do not connect to an app. Choosing between them is therefore less about adding technology to the dashboard and more about finding the control style that fits your routine.
What should you know about charging?
Current LEAFI product information confirms that all three car models are rechargeable without naming the charging connector. Because connector details can vary, confirm the current box contents when the port matters to your setup.
If the connector or included cable is important to your vehicle setup, confirm the current box contents with LEAFI support before ordering. The confirmed practical benefit is cord-free use after charging, not a specific port claim.
Compare the three LEAFI car models
Each model has a distinct reason to choose it:
- X-AIR in Silver uses a 10 ml oil bottle and induction auto start-stop. It runs when you drive and rests when the car stops.
- Y-AIR in Titanium uses a 20 ml oil bottle. It is driving-activated, offers car and home modes, and operates at under 30 dB.
- Z-AIR in Black Gold uses a 10 ml oil bottle. It keeps operation simple with a three-mode button.

No LEAFI unit produces mist. All three car models use waterless cold-air diffusion, so operation has no visible vapour plume.
Which car aroma diffuser fits your routine?
Choose X-AIR for automatic start-stop
X-AIR is the most direct fit when you want the unit to respond to driving without regular button changes. Its induction control handles starting and stopping, while the 10 ml bottle keeps the format compact. There is no app to pair or schedule.
Choose Y-AIR for capacity and two spaces
Y-AIR has the largest oil bottle of the three at 20 ml. Its separate car and home modes make sense when you want to move one rechargeable unit from the vehicle to a desk or shelf. Its verified under-30 dB operation is also relevant when you use it in a quieter room.
Choose Z-AIR for simple manual control
Z-AIR uses a straightforward three-mode button and a 10 ml bottle. It suits drivers who prefer to choose the output themselves rather than rely on automatic start-stop. Set the mode before the journey and leave it in place while driving.
Set the diffuser before the car moves
Place the unit upright on a secure, stable surface where it cannot interfere with the pedals, gear selector, controls or your view. Choose the mode while parked. Start at the lowest setting and only increase it after you know how the fragrance feels in your cabin.
Dubai's Roads and Transport Authority light-motor-vehicle handbook warns that adjusting devices can take attention away from the road. Although the handbook discusses common in-car controls and handheld devices rather than fragrance units, the same sensible rule applies: finish setup before moving and do not reach for the diffuser while driving.
Refill a waterless diffuser correctly
LEAFI's oil rule is exact: pour the pure oil straight into the compatible LEAFI waterless diffuser—no water and nothing mixed in. Use the oil exactly as supplied, and never use it on skin. Keep the bottle away from children and pets, avoid contact with eyes, skin and surfaces, and do not ingest it.
Oil life and battery life are different. A LEAFI oil bottle may last approximately 30–60 days, depending on the model, intensity, daily run time, AC airflow and vehicle size. That range does not describe how long the battery runs between charges, so review the two measurements separately.

Frequently Asked Questions (FAQ)
Which charging connector is included?
Current LEAFI product information confirms that X-AIR, Y-AIR and Z-AIR are rechargeable, but does not specify the connector. Confirm the current box contents if the port matters to you.
Do X-AIR, Y-AIR or Z-AIR need an app?
No. X-AIR uses induction control, Y-AIR is driving-activated with car and home modes, and Z-AIR uses a three-mode button.
Which model holds the most oil?
Y-AIR holds 20 ml. X-AIR and Z-AIR each hold 10 ml.
Can Y-AIR be used outside the car?
Yes. Y-AIR has separate car and home modes, so it can move to a stable desk or shelf when you are not driving.
How should I choose the intensity?
Begin at the lowest setting. Increase it only if the cabin still feels too lightly scented. Reduce the setting or switch the unit off if a passenger finds the fragrance too strong.
