Smith Charcoal Pleated Filters

The charcoal-impregnated pleated filters are made of carbon (coconut shell-based) impregnated synthetic media, containing eight grams of carbon per square foot. The pleats increase the surface area of carbon exposed to the airflow. For example, a 24x24x2 Charcoal impregnated pleat contains 14 square feet of effective media face area compared to only 4 square feet for a filter pad.

Activated carbon is an efficient means of odor control, and this mineral can be found in the Smith Charcoal Filter. These charcoal-impregnated pleats not only act as an odor-removal filter but also as an effective particulate filter.
