Metal-Fab Activated Charcoal Filters

Metal-Fab Activated Charcoal Filters. These activated charcoal filters contain 30 grams of charcoal per square foot of filter media in all sizes 1/2" and thinner. Filters thicker than 1/2" contain at least 90 grams of charcoal per square foot of filter media. Carbonweb filters, such as these, are not partial bypass filters like "Honeycomb" charcoal filters. In carbonweb charcoal filters, all the air going through the filters is exposed to the charcoal for more efficient adsorption. All electronic air cleaners produce some ozone but activated charcoal filters turn this unwanted ozone back into oxygen. All electronic air cleaners should have activated charcoal filters.
