Questions about this diffuser
Where does the mist come from on the steam-train diffuser?
Straight out of the smokestack, like a real locomotive letting off steam. The cool ultrasonic mist rises from the funnel, so the scent effect doubles as the train's steam.
Is the Express more of a display piece or a working diffuser?
Both. It's a finely detailed, collectible locomotive that looks the part on a shelf or desk, and it genuinely diffuses scented mist while it does — no compromise between looks and function.
Does it get hot or use flame like a real train?
No. The mist is cool ultrasonic mist with no heat and no flame, so it's safe to leave on a shelf, desk, or nightstand. The 'steam' from the stack is fine, cool fragrance mist.
Can I use my own oils in the Express, or do I have to buy refills?
Use any diffuser-grade fragrance or essential oil — just add a few drops to the water tank. Our Autivara oils are blended for these units, but there's no required subscription and you're never locked in.
