Abstract
A method for air purification is disclosed, comprising directing air through a particle removal filter that acts to filter the air for particle phase pollutants to thereby produce particulate filtered air; and directing an amount of the particulate filtered air through a gas removal filter that acts to filter the particulate filtered air for gas phase pollutants to thereby produce gas filtered air; the particle removal filter with the first blower and the gas removal filter with the second blower are housed in different enclosures and they are allowed to operate in a way that; the two different units are selectable to operate separately without connection in a first mode, and to operate together connectively in a second mode; when the two different units are selected to operate together connectively in the second mode, the amount of particulate filtered air directed through the gas removal filter is based on a concentration of particle phase pollutants in the air.
