Enhancing air purification.


Air cleaners for volatile organic compounds in indoor air.


Use of air cleaners to reduce outdoor air requirements.


Ventilation criteria: biological demands and formulation of standards.

Methods of controlling indoor air pollution include control, air cleaning and dilution with uncontaminated air. Assessment of the amount of ventilation necessary depends on the extent of pollution, which has increased as new pollutants are identified and new materials are used. This has lead to thereexamination of ventilation standards and their underlying rationale.
