The Dri-Eaz 4-PRO Four-Stage Air Filter is a professional-grade disposable filter designed specifically for dehumidifiers operating in demanding restoration, remediation, and construction environments. Its advanced multi-stage design delivers comprehensive filtration to help dehumidifiers maintain optimum performance and protect your equipment.

This filter’s four-stage media system begins with an expanded cellulose mesh that captures larger particles and debris, followed by electrostatically charged polypropylene that attracts and retains smaller airborne particles often encountered in jobsite air. An activated carbon layer further adsorbs odors and fumes, helping improve the air quality around drying and restoration sites. To enhance protection, the filter media is antimicrobial-treated, reducing microbial growth on the filter surface and contributing to cleaner airflow through the dehumidifier.

Constructed with a sturdy aluminum frame, the 4-PRO filter resists collapse and maintains proper filtration even under heavy loading. The disposable design makes maintenance simple: replace the filter whenever it becomes visibly dirty or heavily loaded with particulates. Using this purpose-built filter in your dehumidifier ensures consistent airflow and efficient moisture removal, which are critical for accelerating drying times and meeting project goals in water damage restoration, mold remediation, humidity control, and other demanding applications.

Whether you’re working in flood restoration, smoke and odor mitigation, or general construction cleanup, the Dri-Eaz 4-PRO Four-Stage Air Filter provides dependable filtration performance that helps protect equipment, personnel, and indoor environments.

This filter can be used on the following Dri-Eaz dehumidifiers: LGR 7000XLi, LGR 5000Li, DrizAir 1400 & DrizAir 1200
