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

Unlike standard water diffusers, the Grand 300™ does not dilute fragrance with water or create damp mist. It uses fragrance oil directly, giving a stronger, cleaner and longer-lasting scent experience designed for homes, shops, salons and offices.

Yes. The Grand 300™ is designed for more than bedside or small-room scenting. Use it freestanding for everyday scenting, or connect it to a ducted air system/HVAC for coverage up to 300m² / 3,000 sq ft.

Connect the Grand 300™ to the Nobl Parfums app via Bluetooth to set weekly schedules, adjust scent intensity and choose exactly when your diffuser runs.

When used as directed, our cold-air diffusion is safe for homes with children and pets. Because there is no heat, flame, or hot water vapour involved, it is one of the safest ways to fragrance a modern home.

Very little. We recommend occasionally wiping the mist nozzle with a soft cloth. When switching between different scents, run the device with a small amount of Isopropyl Alcohol (IPA) for 10 minutes to keep the atomisation system clear and pure.

Yes. Each of our scents is a bespoke creation inspired by the atmospheres of world-leading five-star hotels and iconic luxury spaces.
