Best Spaces
Built for rooms that need more scent presence.
Pro-300 is a strong fit for medium-to-large everyday spaces where smaller portable models may feel too light, but a large floor-standing system may be more than you need.
Large Bedroom
Soft hotel-style comfort
Create a refined bedroom atmosphere with a fuller scent impression than a compact diffuser.
Living Room
Everyday home scenting
Use Pro-300 in living rooms, open seating areas and guest-ready home spaces.
Office
Polished workspace
Support a clean and intentional scent impression for offices, studios and private workspaces.
Spa Room
Relaxed guest atmosphere
Use in spa rooms, treatment rooms or wellness spaces where scent supports the overall experience.
Waterless Cold-Air Diffusion
Designed for a cleaner large-room scent routine.
Pro-300 uses a waterless scenting approach that disperses diffuser oil without mixing it with water or relying on heat.
300ML
Built for longer room scenting
A larger bottle size than personal portable models, suitable for more consistent room fragrance routines.
No Water
No dilution required
Use compatible diffuser oil directly instead of mixing oil with water.
No Heat
Cold-air scenting method
Designed to create a room scent impression without heating the oil.
Control
Adjust for room size
Start with a lower setting, let the scent develop, then adjust based on airflow and preference.
Why Pro-300
The middle step between compact and whole-space scenting.
Pro-300 is useful when you want a stronger machine than a small portable diffuser, but do not need the scale of A-316 or larger HVAC-style systems.
More Capacity
300ML bottle size
Designed for longer use than 100ML personal models and better suited for larger rooms.
More Presence
Larger room atmosphere
Use Pro-300 where you want scent to feel more present in the room without overpowering the space.
More Flexible
Home and work spaces
A strong fit for homes, offices, studios, spa rooms and other medium-to-large interiors.
Choose Your Oil
Pair Pro-300 with full-size oils or refills.
Start with a 100ML hotel-inspired oil if you are choosing a scent. Move to larger refills when the fragrance becomes part of your routine.
First Scent
100ML Diffuser Oils
Best for choosing your first full-size scent before committing to a larger refill routine.
Hotel Style
Hotel-Inspired Scents
Choose a refined scent profile for living rooms, bedrooms, offices and spa rooms.
Longer Use
500ML Refills
Best for customers who already know their preferred scent and want fewer refill interruptions.
Choose Your Diffuser
AE-103, Pro-300 or A-316?
Choose based on space size and how much scent presence the room needs.
Personal Spaces
AE-103
Best for bedrooms, bathrooms, offices, travel and portable room-to-room scenting.
Medium-Large Rooms
Pro-300
Best for large bedrooms, living rooms, offices, spa rooms and studios.
Large Spaces
A-316
Best for villas, hotel lobbies, spas, showrooms and larger guest-facing spaces.
Placement Guide
Give the scent room to move.
For larger rooms, placement and airflow make a meaningful difference. Keep the outlet clear and adjust settings gradually.
Open Area
Avoid blocked corners
Place the machine where the scent can move through the room instead of being trapped in a closed area.
Airflow
Use natural movement
Position near natural airflow paths when possible for a more balanced scent impression.
Intensity
Start low
Begin with a lower setting, then increase gradually based on room size and preference.
Maintenance
Clean when switching
Clean the bottle, tube or atomizer area according to instructions before changing scents.

Should I use 100ML or 500ML oil with Pro-300?
