ABSTRACT:
An apparatus for enhancing the environmental quality of work and living spaces is provided. The apparatus combines a high efficiency particulate air filter, a gas-adsorbent element, a means for moving air, a means for releasing a pleasant odor and a means for sound masking. The odor-releasing means and sound-producing means are designed to improve the affective state, and thereby the task-performance, of persons working in the space being treated. Preferred fragrances 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 which generates pink noise.
