Low rates and easiest to calculate/understand shipping/handling for vent pipe filters
"How do I install the Odorhog™?"
Simply slip the coupling end of the Odorhog™ over the existing vent pipe. You are basically coupling pipe together, except you do not need glue as the connection is snug already.
"Doesn't the filter restrict the airflow?"
The filters do restrict the air flow somewhat. The restriction is so slight that it shouldn't interfere with normal venting of the plumbing system.
"My plumber installed a vent pipe extension. Do I remove the extension or place the Odorhog™ over the vent extension?"
Remove the extension. We have found that when an Odorhog™ is placed over an extension, the whole extension and Odorhog™ assembly act as a "sail" in the wind. The assembly will begin to oscillate in the wind. This could potentially damage your rooftop vent flashing and create a leak in your roof.
"How can I tell when it's time to replace the charcoal in the Odorhog™?"
Your nose will tell you. When you begin to smell the hydrogen sulfide or "rotten egg" smell, it is time to either replace the unit, or purchase a replacement bag of carbon.
"Do I need to order replacement carbon with my initial order of a 3" or 4" Odorhog™?"
Not typically. For standard residential applications, Odorhogs™ will filter odor for up to 5 years. In cases where the carbons may become saturated quickly you might, e.g. commercial or restaurant applications, you may want to order replacement carbon with your initial order.
"Can the I change or replenish the charcoal in the filter?"
Yes. The 2" Odorhog™ is designed as a disposable unit. You may purchase bags of replacement charcoal for the 3" and 4" units. It is recommended that you don't come in contact with the saturated charcoal.
"How do I replace the carbons in the 3" and 4" Odorhog™?"
Pull the metal cap off gently, reach into the unit, grab the carbon bag, dispose of carbon bag, insert new replacement bag, and reinstall metal cap.
"Do the Odorhog™ filters freeze up in extreme cold?"
Even 3" vent pipes with no filters can occasionally clog up with frost if it is cold enough for long enough. This is called "hoarfrost" and you can read about it here. For cold climates (Northern US and Canada) where extended weather of sub-zero temps are likely, we recommend the black ABS models which will absorb a little more heat than the white PVC models.
"What colors do the Odorhogs™ come in?"
We sell them in standard PVC white and ABS black plastic. You may also paint your Odorhog™ to match your roof. However, we recommend that you don't paint the metal rain-cap, so as to keep paint from getting inside.
"What is a Maxi-Filtra™?"
The Maxi-Filtra™ is a device that serves as a two way vent that allows air to pass through a carbon filter and eliminate sewer gas odors.
"Can the Maxi-Filtra™ be installed in an existing system?"
Yes, the Maxi-Filtra™ can be retro-fitted on an existing system.
"Does the Maxi-Filtra™ require maintenance?"
No maintenance is required other than replacing the cartridge.
