Keep plants inside a clean office zone rather than in the dusty production area. Check leaves and surfaces regularly and avoid exposure to sprays, debris, or process materials. The plants need a normal light and watering plan and must not be described as protective equipment or a dust treatment.
The message behind the grouping
Meaning, with a little thought.
The group can mark a deliberate, cared for working boundary. Its role is a visual welcome in the clean office, not a claim that plants remove workplace hazards.
