Purolator hi-E 40™ CB Pleated Filter (16″ x 25″ x 4″)

The Purolator hi-E 40™ CB pleated filter promotes improved indoor air quality through odor control. These carbon-loaded pleated filters clean the air by removing airborne molecular contaminants present at levels less than one particle per million.

• Hi efficiency: Small (20 x 50 mesh) carbon particles and pleated configuration maximize adsorbent surface area
• Low pressure drop: Uniform dispersion of carbon throughout media, not just on surface, lets air flow freely
• Longer filter life, minimal shedding/dusting: thermal bonding of media to carbon exposes maximum adsorbent surface area
• More adsorbent: pound for pound, Purolator’s carbon media is six times more effective than competitive GAC carbons
