Best Spaces
Designed for spaces that need scent to travel farther.
ND-500 is a strong fit for homes and workspaces where room-to-room scenting, airflow and longer-use routines matter more than compact portability.
Whole Home
Connected scenting
Use ND-500 for larger home layouts where one-room scenting is not enough.
Open Living
Large rooms and open plans
Ideal for open-plan living rooms, large common areas and multi-zone home spaces.
Office & Studio
Consistent atmosphere
Use in offices, studios and wellness spaces that need a stable background scent.
Spa & Reception
Guest-ready scenting
A good fit for spa rooms, reception areas and light commercial spaces with regular visitors.
HVAC-Ready Scenting
Built for larger routines, with flexible setup options.
ND-500 can support a stronger scenting routine for large rooms and HVAC-connected spaces, while keeping the scenting process waterless and cold-air based.
500ML
Larger bottle capacity
Designed for customers who want fewer refill interruptions than smaller 100ML or 300ML machines.
HVAC
Whole-home setup path
Use as part of a larger scenting routine when the space benefits from airflow-based scent movement.
No Water
No dilution required
Use compatible diffuser oil directly, without mixing oil with water.
Schedule
Designed for routine use
Adjust scent timing and intensity based on room size, airflow, daily routine and preference.
Why ND-500
The step into larger connected scenting.
ND-500 is for customers who want more reach and refill capacity than a room diffuser, without moving straight into a floor-standing A-316 system.
More Capacity
500ML oil bottle
A practical fit for longer scenting routines and customers who already know their preferred scent profile.
More Reach
HVAC-ready direction
Designed for larger spaces where airflow can help distribute fragrance more consistently.
More Routine
Home or work use
Best for people who want scenting to become part of a home, office, spa or reception routine.
Choose Your Oil
ND-500 is built for refill routines.
Use 100ML oils to choose a new scent, then move to 500ML refills once you find the hotel-inspired profile that fits your home or workspace.

Best for testing a new scent profile before building a longer-use routine.

Placement & Setup
Use airflow to support a more even scent impression.

Airflow
Think beyond one room
Place or connect the machine where airflow can help carry the scent through the intended area.
Access
Keep it serviceable
Choose a location where refilling and routine maintenance are easy to access.
Intensity
Start lower
Begin with a lower setting and increase gradually after the scent develops in the space.
Refill
Plan ahead
For frequent scenting, keep your preferred 500ML refill ready for a smoother routine.
