One of the first questions businesses ask when choosing a commercial scenting system is how often the diffuser needs to be refilled. The answer depends on how the system is used, because every space has different airflow, operating hours, layout, and fragrance requirements.
At OFB, we do not evaluate refill frequency by bottle size alone. A diffuser used in a small office will naturally consume less fragrance oil than a system operating in a large hotel lobby, retail store, showroom, or high-traffic commercial area. The real calculation starts with the volume of the space and the conditions inside it.
Air movement is one of the most important factors. Strong HVAC systems, frequently opened doors, high ceilings, and heavy visitor traffic can cause fragrance to disperse more quickly. In these environments, the device may need to operate more frequently to maintain a stable scent level.
Intensity settings also directly affect consumption. Running a machine at maximum power throughout the day is rarely the best solution. In professional scenting, the goal is not to create the strongest possible fragrance. The goal is to create a balanced, clean, and consistent atmosphere.
This is why OFB systems are planned with scheduled operating intervals and adjustable intensity settings. By matching the diffusion program to the actual opening hours and peak periods of the business, fragrance oil can be used more efficiently while keeping the scent experience stable.
Placement is another important detail. A diffuser positioned too close to an open entrance or directly beside a strong air outlet may lose much of its fragrance before it reaches the intended area. Correct positioning helps the scent spread more evenly and reduces unnecessary consumption.
The most reliable method is to monitor the system during the first weeks of use. Oil levels, daily performance, and scent consistency should be checked regularly. Once the correct intensity and schedule are established, refill planning becomes much easier and more predictable.
At OFB, each scenting solution is evaluated according to the needs of the location rather than using a standard setting for every business. Space size, ceiling height, airflow, operating hours, and the desired scent effect are all considered together.

In conclusion, refill frequency is not fixed. It is shaped by space conditions, device settings, operating time, and placement. With the right planning, a commercial scent diffuser can deliver a consistent atmosphere while using fragrance oil efficiently.
