An AI video brief for a compact air purifier: the invisible, made visible. AI renders a cosy bedroom where dust and pollen particles glow and drift through the air — then stream toward the purifier until the air runs clear. A classic shock-reveal structure, upgraded from gross-out to wonder. Hooks (text + VO): "This is what 'clean air' actually looks like in your bedroom." / Open on the particle storm: "You're breathing this tonight." / "I bought it for allergies. I keep it for this visual." Script (25–30s): the particle-storm bedroom at night, the purifier switching on and the air clearing while
the sleeper stays undisturbed, then morning light and clear air with a one-line benefit, and a real-photo product hero to close. Production notes: four AI shots plus the real unit shot; the bedroom must look lived-in, not sci-fi. Format: 9:16, captions. The particle visual is illustrative (labelled a visualisation where the brand's compliance requires it); no medical or allergy-cure claims, and performance numbers only as tested. Iteration: a room series — the nursery version is the emotional v2, with claims care doubled — plus a seasonal pollen version timed to spring.
Spec brief — created as a portfolio sample, modelled on proven scaling ads. Not client work.
