History
From CP Environmental Filters to CPE Filter Systems
The company was founded as CP Environmental Filters, supplying dust collection equipment to Midwestern industry at a time when most plants treated particulate capture as an afterthought.
Under Mark Sternisha’s leadership across four decades, it grew from a regional supplier into a business known for custom-engineered systems, conservative sizing, and long-running customer relationships — several of them now measured in decades rather than years.
In 2026 the business was acquired by 4N Filtech LLC and adopted the CPE Filter Systems name, with Mark continuing as President Emeritus.
