OdorHog's Superior Design
What sets OdorHog apart is the superior design!
The replaceable mesh bag inside the filter body contains high quality, pelletized carbon that's activated for the Hydrogen Sulfide molecule (that stinky odor).
Because of this replaceable mesh bag, changing your carbon out has never been easier and can be done while the OdorHog remains on the vent pipe! Just remove the cap, pull the old carbon bag out by the handle, put the new bag in and put the cap back on.
One trip up the ladder with a replacement bag does the job. Fresh carbon in minutes! Lasts for years!
With other brands, the change outs can be messy, especially if they have loose charcoal or charcoal chards. These charcoal chards also cause added restriction as they age because they fuse together into a clump and can clog the sewer pipe, backing up odors into the home.
Then, when it's time to change out that loose charcoal, the filter will need to be taken down from the roof vent pipe and the pasty glob of loose, stinky charcoal will need to be washed out with a garden hose before refilling. You can imagine spraying out sewer filled, charcoal paste from a narrow tube, making disposal of the old charcoal difficult at best.
Who wants to make two trips up on the roof when one is all you'll need with OdorHog.
