Shared means variable
Airports, hospitals, museums and transit systems can smell different by time, occupancy and maintenance.
EXPLAINER
Smell & Public Spaces
Public places combine materials, cleaning, ventilation, food, people and local routines into shared smell environments.
Restraint matters
In shared or sensitivity-critical environments, added fragrance may be inappropriate.
Context should stay visible
SmellBook treats a public-space profile as a place experience, not a fixed chemical signature.
Public-space profiles do not certify cleanliness, safety, accessibility or indoor-air quality.
