Bottle size and refills
A bigger bottle means fewer refills between visits, which matters in a busy business. To estimate how long a bottle lasts, divide its size in ml by the diffuser's oil use per hour; our guide on how long a bottle of diffuser oil lasts shows the method.
Setting up a commercial diffuser
- Size for the space you want scented, not the whole building, if back rooms stay unscented.
- Place it where air circulates, near the entrance or a main walkway.
- Schedule it for opening hours, so oil isn't used overnight.
- Choose one signature scent and keep it, so customers connect it with your brand. See scent marketing for Tampa Bay businesses.
Frequently asked questions
Do commercial diffusers need water?
No. They are cold-air diffusers that turn pure fragrance oil into a fine, dry mist, with no water or heat.
Can I use more than one unit?
Yes. Separate rooms, floors or zones are often better served by one unit each than by a single large one.
Can you help us choose?
Yes. See Business Scenting, the hotel and gym pages, or email info@tampascents.com with your floor area.
