Frequently asked questions
What is AMBRUNE?
AMBRUNE is an aroma and home-fragrance store offering ultrasonic diffusers, waterless scent devices, diffuser oils, and related accessories.
Which diffuser should I choose?
Choose by room size, fragrance format, and how often you want to refill. Ultrasonic diffusers use water and compatible oil. Larger reservoirs support longer sessions. Waterless cold-air diffusers disperse concentrated fragrance without a water reservoir.
Can I use any oil in any diffuser?
No. Ultrasonic diffusers should use essential oils or water-compatible diffuser oils. Waterless diffusers require oils suitable for cold-air diffusion. Never add carrier oils, body oils, reed-diffuser liquid, or thick resins to an ultrasonic reservoir.
How much oil should I add?
Start with the amount recommended on the oil label and product guide, then adjust conservatively for room size and preference. More oil does not always create better mist or fragrance.
Why do some products offer different plug options?
Several diffusers are available with regional plugs. Select the plug that matches the electrical outlets and voltage requirements of the country where the product will be used.
How do I clean my diffuser?
Empty unused water or fragrance, unplug the device, and follow the supplied guide. Visit our Product Care page for general ultrasonic and waterless-diffuser guidance.
