Permaire Media Rolls are naturally rigid. Once cut to the proper dimensions, they are complete filters ready to install, no frame required. As dust particles pass through the filtration media, they become naturally charged and are attracted to the opposite charge on the filter fibers. Dust, lint, and pollen collect throughout the filter's depth, allowing it to hold more contaminants for fewer filter changes with improved air quality.
