Frequently Asked Questions
MUJI offers a few different diffusion methods:
- Ultrasonic diffusers create fine mist through vibrations, dispersing essential oils while adding gentle humidity.
- Nebulising diffusers use air pumps to directly atomise oils without water for concentrated fragrance.
- Ceramic aroma stones provide heat-free diffusion through natural evaporation, absorbing 5-10 drops of oil that release gradually over time.
Yes, some MUJI diffusers include customisable features for various situations. Adjustable lighting dims to your preferred ambience, timer functions automatically shut off after set periods (typically 2 hours), and mist output can often be controlled. Coverage ranges from 9-25 square metres, depending on model, allowing you to match diffuser capacity to specific room sizes.
Regular cleaning prevents oil buildup that affects mist quality.
- For ultrasonic models, wipe the vibration plate with a soft cloth between uses.
- Nebulising diffusers include maintenance bottles for switching oils — fill with rubbing alcohol and run briefly to clean internal mechanisms.
- Ceramic stones simply need rotation to utilise fresh absorption areas.
