Keep your dehumidifiers operating at maximum efficiency with the only filter designed specifically for restoration, remediation and construction. Protects in four ways: electrostatic polypropylene and cellulose mesh capture particles, while activated carbon absorbs odors and fumes and antimicrobial treatment helps prevent bacterial growth on the filter. FEATURES: Expanded cellulose mesh captures large particles. Electrostatically charged polypropylene attracts and retains smaller particles. Activated carbon adsorbs odors and fumes. Antimicrobial-treated layers helps prevent bacterial growth and associated odors. Sturdy aluminum frame resists collapse and maintains proper filtration.
