Frequently Asked Questions
Which oils can I use, and how do I care for my diffuser?
For best results, use pure, water-free fragrance oils formulated for cold-air diffusion — like the AURESCENT fragrance oil range. Avoid water-based or essential-oil blends with carriers, as these can clog the nozzle. Maintenance is minimal: occasionally run the unit briefly with a little alcohol-based cleaner to keep the atomizer clear, and wipe the exterior with a soft, dry cloth.
How does a cold-air (nebulizing) diffuser work?
Our diffusers use waterless "cold-air" nebulizing technology. Instead of heating or diluting the oil, they use pressurized air to atomize pure fragrance oil into an ultra-fine, dry mist. This preserves the scent exactly as intended, spreads it evenly through the room, and leaves no water residue on surfaces.
Which diffuser size is right for my space?
Choose based on the area you want to scent. Compact models suit bedrooms, bathrooms and small offices; mid-range models cover living rooms, lobbies and medium spaces; and our high-capacity models are built for large open-plan homes, showrooms and commercial interiors — including HVAC-integrated whole-building coverage. Each product page lists its recommended coverage in m² / m³.
