| Compare | Direct approved-oil format | Water-based format |

| Upkeep | Supplied oil-machine instructions | Supplied tank instructions |
Clarify what oil-based means
Ask whether the term describes direct oil diffusion, a proprietary cartridge or simply the refill composition. The label alone does not identify mechanism or commercial coverage.
Clarify the water procedure
For a water-based device, request water-fill levels, approved blend quantities and cleaning instructions. Do not assume every water diffuser uses heat or the same technology.
Compare workload and costs
Review filling, cleaning, oil use, staff availability and operating hours. Similar tank volumes are not comparable consumption figures when the liquids differ.
Choose the approved pairing
HUME’s listed cold-air commercial format should be used according to its supplied instructions and approved oil. This page does not establish approval for adding water or replacing that oil with another format.
Before you accept a quote
- Identify the proposed zones and areas to leave unscented.

Buyer questions
Can I dilute machine oil with water?
Only if the exact model and oil instructions explicitly permit it.
Does a 400ml water tank equal 400ml oil capacity?
No. The stated tank contents and fragrance quantities differ.
Which costs less each month?
A model-specific usage estimate and refill quote are required.
