The Purolator® Puro-Green® is a high-efficiency, pleated air filter which meets the minimum efficiency criteria required by LEED (Leadership in Energy and Environmental Design). The filters are ideally suited for use in buildings where better indoor air quality is desired, such as existing commercial properties, universities, school systems and government institutions. They can be used a pre-filter or final filter without the need to retrofit systems for a high-efficiency rigid filter. In most cases, the filters qualify as a sustainable component for a LEED/Green Building Initiative.Puro-Green® filters are available in multiple sizes (1-, 2- or 4-in thickness) and utilize heavy-duty beverage board frame made from moisture-resistant material and double-walled thickness around the outer edge. This, coupled with integral die-cut cross members, provides the necessary rigidity to help maintain the pleat shape and prevent fluttering during operation. The consistent pleat shape maximizes the overall performance of the filter and contributes to balanced dust-loading. Moisture resistance is provided by the water-repellent adhesive, which bonds the frame with the media pack and covers 100% of the interior of the frame. This ensures that pleats hold together when wet, preventing delaminating, excessive buckling, collapsing, racking, warping, and bending, which can cost users time and money.
