Keep your dehumidifiers operating at maximum efficiency with the 4-PRO Four Stage Air 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.

CONSTRUCTION: Sturdy aluminum frame resists collapse to maintain proper filtration.

MATERIALS: Electrostatically charged polypropylene, activated carbon, and expanded cellulose mesh. Antimicrobial-treated filter media.

DISPOSABLE: Filters are not reusable. Replace whenever filter appears dirty or heavily loaded with particles.
