Choosing a waterless diffuser based on cubic meters ensures even scent distribution without over- or under-scenting.


2. Select the Right Installation Method
Different commercial spaces require different installation solutions. Below are common scenarios and recommended fragrance diffuser types.
Small Spaces (Restrooms, Corridors, Elevators)
For compact areas, a wall-mounted fragrance diffuser is the most practical choice.

Large Spaces with Central Air Conditioning (HVAC)
If your commercial space operates with a continuously running central air conditioning system, an HVAC-connected scent machine is ideal.

- Discreet installation
- Suitable for hotels, shopping malls, and office buildings
Restricted HVAC Control Rooms
In some hotels or commercial buildings, the HVAC control room is not accessible to external operators. In this case, a split-type scent diffuser connected to the HVAC system is the best solution.

- Diffusion system connected to HVAC ducts

Large Spaces Without Central Air Conditioning
For hotel lobbies, reception areas, exhibition halls, or open spaces without HVAC systems, a standing commercial aroma diffuser with a powerful built-in fan is recommended.
- Strong independent diffusion
- Flexible placement
- Ideal for high-ceiling and open environments
Retail Stores and Boutique Spaces
For smaller brand stores or premium retail environments, a mid-to-high-end aluminum desktop fragrance diffuser offers both performance and aesthetics.
