Abstract

A system for detecting and cleaning indoor air pollution adapted to be utilized in an indoor space with an HVAC system includes one or more outdoor gas detection devices, a plurality of channels, a plurality of indoor gas detection devices, a plurality of physical-typed or chemical-typed filtering devices, and a control central processor. The blower of the filtering device receives a control command so as to be driven and to generate an air convection which is directed. Therefore, the air pollution is filtered by the filtering component to allow the indoor air pollution data to approach to almost zero, so that a gas in the indoor space is cleaned to a safe and breathable state.
