Abstract
The present invention is a system or device and method of providing air purification in combination with fragrancing in a single unit, such as a tabletop unit for home or office use in conjunction with a method of optimizing the air delivery rate versus noise specification of an air freshening device. The air freshening unit includes a housing, an air movement mechanism, a pre-ionizer, a filter, a post-ionizer, a diverter for directing airflow to a non-fragranced air exhaust port and to a multiple fragrance delivery system, which supplies a fragranced air exhaust port. Additionally, the multiple fragrance delivery system can be formed of a wick-based delivery system incorporating a capillary member, or a fragrance bead delivery system. The air freshening unit of the present invention can also include a fragrance mechanism integrated directly into the filter mechanism.
