How long does each refill last?+
Around 90 days under normal driving — earlier on the highest interval setting, longer on the gentlest. Your Type 01 will tell you when it's time, but most owners notice the natural fade and swap intuitively.
Can I switch scents mid-life, or do I need to finish one first?+
Switch any time. Lift the partially-used refill out, store it sealed, and drop in a different one. Many owners rotate seasonally — Spectra in summer, Noir-V through autumn, Velora into winter. The bottle resumes where it left off when you swap back.
How do I know when to replace?+
Three signals: the scent reads thinner than usual on the highest interval, the bottle visibly empties when held to light, or roughly 90 days have passed. There's no warning light — by design. The diffuser stays composed; the fade is gradual.
Can I buy a single refill, or only pairs?+
Single refills, £50 each. The set you originally received included two as a starter — from here, you choose what you need. Many owners keep two on rotation, but it's entirely up to you.
Will refills work with future Type versions?+
Type 01 refills are designed for Type 01. When the next generation launches, we'll communicate compatibility clearly — no surprises, no obsolescence. Anyone owning a Type 01 will be able to keep it running with current refills as long as the diffuser itself works.
Can I gift a refill to another owner?+
Yes. At checkout, add a gift note and send to a different address. The packaging is brand-grade — refills arrive in the same considered presentation as the original set.
What's your return policy on refills?+
Unopened refills can be returned within 30 days for a full refund. For sealed bottles you've opened, we can't accept returns for hygiene reasons — but if there's a quality issue with what you received, contact us directly and we'll make it right.
