Read the technology description
HUME’s 400ml model lists cold-air nebulization. A heat-based device uses a different release mechanism. Water-based ultrasonic equipment can operate using vibrations, so water does not imply heat.
Verify formulation and placement
Ask what liquids or materials the exact model permits and follow its positioning instructions. Do not transfer a fragrance between heated and cold-air devices without explicit approval.
Avoid unsupported superiority claims
This guide does not claim that every cold-air product outperforms every heated product or that either technology creates a health benefit. Evaluate the supplied specifications and intended use.
Compare the business routine
Review operating hours, controls, refill procedure, maintenance and staff responsibilities. Select for the zone and approved setup, then confirm the quote’s inclusions and support.

Buyer questions
Are ultrasonic diffusers heated?
Water-based ultrasonic formats can use vibrations rather than heat; verify the model.
Can heat-device fragrance go into HUME equipment?
No compatibility is established. Use approved machine oil.
Does cold-air mean a guaranteed refill interval?
No. Refill timing depends on output, hours and model-specific consumption.
