Abstract: Provided are purification systems and methods of using such systems for purifying various environments, such as indoor air, outdoor air, vehicle emissions, and industrial emissions. A purification system comprises an ionizing purifier having a substrate and an active coating. The active coating comprises a pyroelectric and/or piezoelectric material. During the operation, an incoming stream is directed toward the active coating while controlling the average pressure exerting on the active coating. This contact between the incoming stream and the active coating generates negative ions from components of the incoming stream via change in temperature and pressure/force/vibration, etc. The negative ions then interact with pollutants, transforming them into safe, purified materials of the outgoing stream. Unlike the pollutants in the incoming stream, the purified materials are non-harmful, and/or can be easily removed from the outgoing stream, e.g., by filtering and/or other separation techniques.
