Box Filters

MiniFlow

MiniFlow Series are compact, space-saving 4″ deep high-efficiency air filters.

They feature wet-laid microfine glass media in a pleated design for optimal airflow, low system resistance, and extended service life. Efficiency is maintained throughout the filter’s life in HVAC systems.

With low pressure drop and full use of media area ensured by thermoplastic resin separators, MiniFlow filters deliver uniform airflow and reliable performance. The high wet-strength frame resists moisture, and the media pack is guaranteed against failure up to 5.0″ w.g. Available in a variety of sizes to suit virtually any application.
