most kirri oils last somewhere between one and twelve months. it depends on the bottle size, your diffuser and how many hours it runs.
how long each size lasts
- micro oil (15ml): around 1 to 3 months in an element or micro diffuser
- macro oil (30ml): around 2 to 6 months in a beacon
- aura oil (100ml): around 6 to 12 months in a beacon or pillar
these are typical times, not guarantees. your settings make the biggest difference.
how to make your oil go further
- run a schedule: set the hours you're home in the kirri app, so it isn't scenting an empty house
- start on delicate: scent builds over days, so the lowest setting is often all a room needs
- keep the nozzle clean: run kirri cleaning solution through it for 5 to 10 minutes each time you change scents, or when output drops
- go bigger: 100ml aura oil costs about 40% less per ml than 15ml. 15ml vs 100ml: which costs less to run?

when to reorder
- 15ml: check the level after a month
- 30ml: check it after two months
- 100ml: check it after six months
- never run out: a refill plan sends your next bottles before you need them
