Abstract
Methods and systems are provided for enhancing the air quality in buildings during a chemical and/or biological attack and/or when the air quality around a building drops to unacceptable levels. Preferably, relatively non-contaminated (clean) air is stored in one or more clean air reservoirs. Once stored, the clean air is selectively delivered to buildings when a chemical and/or biological attack is detected, and/or when the air quality around a building drops to unacceptable levels.
