Purolator Puro-green 13
The Puro-green 13’s heavy duty beverage board frame is made using moisture-resistant, sturdy frame material that stands up to rough handling and difficult service conditions. As such, expect a long service life in the field. Because of moisture-resistant media and construction, the pleats hold together even when wet, preventing delaminating, excessive buckling, collapsing, racking, warping, and bending. Additionally, the double-walled thickness around the outer edge and rust-resistant galvanized steel frame help maintain pleat shape and prevent fluttering during operation.


  • The Puro-green 13 can be used in almost any building where better indoor air quality is desired such as existing commercial properties, universities, school systems and government institutions. It can be used a pre-filter or final filter without the need to retrofit systems for a high-efficiency rigid filter.
