The EC Series washable MERV 5 Electrostatic Filter is a permanent washable panel filter designed to replace disposable air filters commonly used in residential, commercial and industrial HVAC applications to remove airborne particulate from the airstream. It uses a “passive electrostatic” media combination which increases its initial efficiency to MERV 5. A polypropylene media generates an electrostatic charge as air passes through it, and airborne pollutants such as dust, pollen, mold, bacteria and lint particles are held in place until washed away. Corner drain holes prevent water and detergent from pooling when cleaning and, therefore, facilitate faster drying time. The EC Series is an ideal permanent filter solution for home heating, cooling and ventilation systems.

The EC Series uses a mill-finished aluminum frame to enclose an electrostatic media pack. The media pack includes one layer of polyester media and one layer of polypropylene between two expanded metal face guards. The pack is made to fit firmly inside the frame giving the filter exceptional strength and durability. The frame is made with mitered corners and is secured with pop-rivet(s). The frame has drain holes in three corners.

Filter Cleaning and Coating
1. The EC Series should be cleaned every 30 days, or as often as necessary to maximize effectiveness. As with any filter, as dust loads it’s efficiency diminishes and air resistance increases, so a well-maintained filter will last longer and cost less.
2. To clean a dirty filter, rinse it with a moderate-to-heavy stream of warm water in the opposite direction of the airflow. Pre-soaking the filter in a solution of warm water and mild detergent prior to rinsing is acceptable. High-powered steam cleaning or chemical dips are unnecessary and not recommended.
