QUESTIONS?
EVERYTHING YOU NEED TO KNOW.
How does Grand 300™ work?
Grand 300™ uses waterless diffusion to disperse fragrance oil as a fine, dry mist, helping scent your space without heat or added water.
Does it require water?
No. Grand 300™ works directly with fragrance oil and does not need water.
How large an area can it scent?
Coverage depends on room layout, airflow and your chosen intensity. For best results, place the diffuser in an open area and adjust the output to suit your space.
How do I control it?
Use the diffuser’s controls to select your preferred fragrance intensity and operating settings.
Can I create schedules?
Yes. Set operating times to fit your routine and help manage fragrance use throughout the day.
Can it connect to HVAC?
Yes. Grand 300™ includes a hose that can route fragrance mist into suitable HVAC ductwork for wider distribution. It also works fully standalone.
How long can a 200ml fragrance last?
Usage time varies with your schedule and intensity settings. Lower output and shorter operating hours can extend the life of a 200ml bottle.
Which fragrance oils can I use?
For optimal performance, use fragrance oils formulated for Grand 300™. Other oils may affect diffusion or device performance.
What comes in the box?
The box includes the Grand 300™ diffuser and the accessories specified on the product listing. Fragrance oil is included only when stated in the selected offer.
What is the warranty and returns policy?
Warranty coverage and return eligibility are subject to the terms shown in our current warranty and returns policies. Please review those policies or contact our support team for help.
