A portable clean molding apparatus for receipt of molded articles ejected from a mold machine. The apparatus includes a receiving chamber having a first interior space and a selectively openable first door, a secondary chamber joined to the receiving chamber and having a second interior space and a selectively openable second door, and an air filtration cover unit installed over the receiving and secondary chambers so as to provide a low-particulate, positive airflow into the first and second interior spaces. The apparatus further includes at least one vent communicating with the second interior space so as to allow the airflow to exit the secondary chamber and at least one chute communicating with the first interior space so as to allow the airflow to exit the receiving chamber, the chute being located adjacent to the mold machine for the transfer of molded articles to the receiving chamber.
