How we test
The full processReal homes, real weeks
Every diffuser runs in a reviewer's own home for at least 2 weeks: kitchens that smell of last night's dinner, hallways with draughts, bedrooms that need subtle.
The arithmetic brands skip
Running cost per hour of scent, coverage claims against reality, and what refills cost over a year. If the sums do not work, the score says so.
