Easy-Install Electrostatic Reusable Panel Air Filters

Magnetic strips on the back of the frame make these filters easy to install and remove. Because you don’t need to disassemble equipment to remove them, they are often used as prefilters on steel air intake louvers, metal cabinets, and metal grid systems. Made of polypropylene, an inherent electrostatic charge attracts dust and particles to these filters. They can be washed and reused.
