Compatibility checklist
Scent paths
Use the scent goal to narrow the collection. Cold-air machines can make a fragrance feel larger and cleaner than a water-tank diffuser, so start lower and increase after the scent has circulated.
Polished tea, citrus, woods, amber and clean musk profiles for entryways, living rooms and guest spaces.
Designer-inspired amber, citrus, woody, floral and fresh profiles when you want the room to feel intentionally scented.
Clean florals, eucalyptus, tropical air, spa notes, soft woods and fresh laundry-style fragrance oil scents.
Refill intent
When your scent output drops or the bottle is low, refill with a waterless fragrance oil that matches your machine type. Use Aroma Paradise oils for compatible cold-air, nebulizing and HVAC scent systems; use regular oils only for water-tank ultrasonic diffusers.
Browse diffuser oil refills by hotel, perfume, fresh, clean, woody and spa-style scent families.
