CUSTOMER CARE

QUESTIONS, ANSWERED.

Everything you need to know about NOBL products, fragrance oils, delivery and aftercare.

Grand 300™

How does the Grand 300™ diffuser work?

Grand 300™ uses waterless cold-air diffusion to turn fragrance oil into a fine, dry scent mist. There is no water or heat — just consistent fragrance throughout your space.

How is it different from a water diffuser?

Grand 300™ uses fragrance oil directly without adding water. This provides a stronger, cleaner scent and removes the need to regularly refill a water tank.

How large an area can it scent?

Grand 300™ is designed for larger spaces up to approximately 300 m² / 3,000 sq ft. Use it freestanding or connect it to compatible HVAC ducting.

How do I control when it runs?

Connect Grand 300™ to the NOBL Parfums app via Bluetooth to set schedules, adjust scent intensity and control when your diffuser operates.

Can it connect to HVAC?

Yes. Grand 300™ can be used freestanding or connected to compatible HVAC ducting for wider fragrance distribution.

What maintenance does it need?

Keep the diffuser and nozzle clean and free from oil build-up. For deeper cleaning, use 91–95% isopropyl alcohol according to the NOBL care instructions.

Fragrance oils

How long does a 200ml fragrance bottle last?

Typically around 2–4 months depending on your schedule, scent intensity and space. Longer pause periods between scent cycles can significantly extend bottle life.

Which fragrance oils can I use?

For best performance, use fragrance oils designed for waterless cold-air diffusion. NOBL 200ml fragrance oils are made specifically for this type of system.

Do I add water to the fragrance oil?

No. NOBL fragrance oils are used directly without water or dilution.

How do I choose the right fragrance?

Midnight Lobby™ is polished and floral-green, Cashmere Woods™ is warm and woody, Silk White Tea™ is clean and spa-like, and Signature Aura™ is bright and fruity-floral.

Can I try the fragrances before buying a full-size bottle?

Yes. The NOBL Discovery Set™ includes all four signature fragrances in 15ml bottles so you can find your favourite before moving to 200ml.

Are the fragrances inspired by luxury hotels?

NOBL fragrances are designed around the polished, refined atmosphere associated with luxury hotels and premium interiors.
