Carbon
filters are no longer just for the intake side of your air filtration
system. Now they can be installed in-line with the lights and fans. The
Phresh 701180 8-inch in-line carbon filter is built into an air tight
conserving body that is capable of filtering 750 CFM. With built-in
flanges, the Phresh in-line filters are state of the art carbon filters
that scour the air to clean it of foreign particulates, dust, organic
compounds and odors. Phresh Inline Filters last twice as long and are
twice as light as other filters of the same size.
