The unit should be placed in a location that pulls the contaminated air away from the living or sleeping space.
For ex: In a bedroom, the unit should be placed in the corner and furthest from the head of the sleeping individual, thus pulling the untreated air away from that person.
In commercial businesses, the unit should be placed in the furthest corner of the waiting area or application area.
For highest performance and effectiveness, always place the unit furthest from individuals, drawing untreated air away from staff and customers.
