How long does a 100ml Wood Diffuser Refill last?Updated 2 hours ago

Each 100ml Wood Diffuser Refill lasts approximately 4 to 8 weeks, depending on your chosen intensity level and usage schedule. Lower settings used intermittently will extend longevity, while higher output or continuous use will shorten it.

To maximise performance:

• Ensure the bottle is securely attached

• Use only Kirri refills for compatibility and safety

• Store spare oils in a cool, dark place away from direct sunlight

Our extrait de parfum oils are highly concentrated and IFRA-compliant, meaning you need less to create a lasting impression.
