Indoor remediation Environmentalist designed. Field tested. 

The CPD Filter was designed and invented by a veteran environmentalist with years of mold remediation, abatement, and mitigation industry  experience. It was created to answer one of the industry's most frequent nuisances and the companies who have tested it, love it.

Before [using] this new product we used to use prefilters attached to wall containments. They were not efficient, the risk to contaminate areas out of containment was high. Now with the CPD I’m not afraid of that risk.
