The In-Line OdorHog™ is a commercial grade septic and sewer filter that installs in the attic. This vent pipe filter utilizes our specially formulated commercial grade charcoal. It comes with (2) Heavy Duty "Clamp On" Rubber Couplings. No glue required.

If your vent stack is hard to reach, if you live in an extreme cold climate or your HOA requires your OdorHog vent pipe filter to be hidden, then the In-Line OdorHog is an ideal alternative.

The In-Line Filter also has many marine applications and are used frequently in Yachts, Ferry Boats and Commercial Fishing Vessels.

Each OdorHog has a replaceable mesh bag inside the body, with pelletized charcoal that is activated for the H2S molecule. Our Commercial grade charcoal is made from a coconut shell based carbon that has a higher sewer gas absorption capacity and is made for longer life. It is perfect for heavy hydrogen sulfide applications.

OdorHog is designed for passive or ambient air flow and are not suitable for applications where blowers or fans push or force air.
