<p>An apparatus for enhancing the environmental quality of work and living spaces is provided. The apparatus combines a high efficiency particulate air filter (2), a gas-adsorbent element (3), a means for moving air (5), a means for releasing a pleasant odor (11) and a means for sound masking (7). The odor-releasing means (11) and sound-producing means (7) are designed to improve the affective state, and thereby the task-performance, of persons working in the space being treated. Preferred fragances are citrus, floral, eucalyptus and mint, released at about 1 to 20 mg/hr. The sound masking is preferably accomplished by a sound-generating device (7) which generates pink noise.</p> |
