ABSTRACT:
An air filter is provided for removing gaseous impurities from the air such as formaldehyde, acetaldehyde, acrolein, acetone and other chemical compounds. The filter utilizes a plurality of corrugated base sheets which are stacked or nestled and which have entrapped carbon dust for absorption of impurities. The corrugated structure provides very little pressure drop as the air passes through available channels and large, powerful fans are not necessary to move air therethrough.
