Vent Pipe Filters for Bad Septic Odors


Offensive odors vented from your septic system are a thing of the past. Odorhog Vent Pipe Filters can be attached by most homeowners themselves in minutes. They last for years and as an added bonus they can prevent snow and leaves from clogging your vent stack. Odorhog even eliminates odors coming from RV holding tank vent pipes as well as marine holding tank vent pipes. Large waste water facilities have used the Odorhog to eliminate unwanted hydrogen sulfide odors.

Eliminate Septic Tank Odors

-- Eliminates foul air pulled inside from air conditioners
-- No more stinky air drifting through open windows
-- Enjoy fresh air during your patio parties, pool parties, barbecues, etc.

Odorhog Vent Pipe Filters
Odorhog vent pipe filters
Odorhog is a great way to eliminate septic tank odors! It's an activated carbon filter that can prevent septic tank odors by removing Hydrogen Sulfide (an offensive odor) as they come out of the vent on the roof. Odorhog eliminates unpleasant odors from house vents as well as RV and marine holding tank vent pipes and even septic pumping vehicles.
The Odorhog is available with the metal cap as shown above, or a mushroom cap. There is no functional difference between the two caps. Some customers like the metal cap because it looks like their furnace vent. Other people prefer the mushroom cap because it is made of durable PVC plastic.

Benefits and features:
  • Removes Hydrogen Sulfide from your septic tank
  • Easy to install - slips right on the vent pipe on the roof
  • Filters odor for up to 5 years
  • Every plumbing vent on the roof must have a filter in order to eliminate the septic odor
  • Replacement bags of charcoal are available for 3", 4" and 6" models

  • NOTE: 1.5" and 2" are only available with T-vent (no metal cap available on these two sizes

The Powerhog is a dynamic activated carbon vent pipe filter. It is active, as opposed to passive. The Powerhog has a small fan in the cap portion which draws the odors up and out of the septic system through the Odorhog. The ultra quiet fan extracts 680 cubic feet of Hydrogen Sulfide (unpleasant odor) per hour, eliminating gases that are hazardous to your health and the environment.

The standard Powerhog uses solar cells to power the fan during daylight hours. These fans need sunlight to run. Accumulation of snow or hail may cause the fan to stop running.

The Powerhog Plus uses sunlight to run during the day, and a rechargeable solar battery to run the fan at night. The battery will run for up to 48 hours.

Both the Powerhog and the Powerhog Plus now come with a Stainless Steel solar fan assembly.

Benefits and features:
  • Removes Hydrogen Sulfide (bad smell) from your septic tank
  • Easy to install - slips right on the vent pipe on the roof
  • No glue needed to install. Just tighen the stainless steel clamps with a screwdriver
  • Ultra quiet fan exhausts unpleasant order at a rate of 680cfh
  • Both the Powerhog and the Powerhog Plus have a stainless steel fan assembly (top)
  • Standard Powerhog uses solar power to run exhaust fan - no electrical wiring to install
  • Powerhog Plus uses solar energy to run during the day and uses a rechargeable solar battery to run at night - the battery is charged during the day by the solar panel
  • Replacement bags of charcoal are available

Please note: While we strive to ensure every product we label as "Made in the USA" really is 100% made in the USA, it is also important to understand that sometimes manufacturers make changes to their products, or for various reasons may receive components or materials that they would normally purchase domestically from an overseas supplier - and they don't necessarily let distributors (like us!) know that they've changed something about the product or where it is manufactured.

If you receive a product that PlumbingSupply.com® says is "Made in the USA" and the product states it was manufactured elsewhere, please contact us. We will happily replace or refund your purchase to your satisfaction.

Frequently Asked Questions

Q. "How do I install the Odorhog?"
A. 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.

Q. "Doesn't the filter restrict the airflow?"
A. 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.

Q. "My plumber installed a vent pipe extension. Do I remove the extension or place the Odorhog over the vent extension?"
A. 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.

Q. "How can I tell when it's time to replace the charcoal in the Odorhog?"
A. 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.

Q. "Do I need to order replacement carbon with my initial order of a 3" or 4" Odorhog?"
A. 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.

Q. "Can the I change or replenish the charcoal in the filter?"
A. 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 directly.

Q. "How do I replace the carbons in the 3" and 4" Odorhog?"
A. Pull the metal cap off gently, reach into the unit, grab the carbon bag with gloved hands, dispose of carbon bag, insert new replacement bag, and reinstall metal cap.

Q. "Do Odorhog filters freeze up in extreme cold?"
A. 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" (also known as readiation frost), which is a type of frost created when loosely distributed white ice crystals are deposited on the ground or other exposed items (such as leaves, branches, other vegetation, fence posts, etc.), which then results in frost that forms as the item gets colder than the air surrounding it due to heat loss from radiation. 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.

Q. "What colors do the Odorhogs come in?"
A. 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.

Q. "Will the OdorHog reduce indoor septic odor?"
A. Only if the outdoor odor from the roof vent pipe is being pulled in through windows or roof top air-conditioners. The OdorHog is designed to filter out septic odors coming from vent pipes on the roof and are not designed to reduce odors that originate from inside the house.

Q. "How long will the fan on the PowerHog last?"
A. This is a difficult question to answer. The manufacturer states that due to the widely varied applications these fans are put to, they cannot offer a standard expected life span. However, they do have an extremely high reliability rate - the manufacturer states that with the exception of fans used without filters in caustic environments, virtually all fans installed during the initial release are still in service.

Q. "Will the fan on the PowerHog work during overcast weather?"
A. These solar powered fans have been installed all over the country and per the manufacturer, all reports show the fans working just fine even in places like rainy Seattle. The manufacturer does suggest that if you're concerned about cloudy day performance, the PowerHog Plus might ease your mind. They did point out, however, that a covering of snow will prevent the solar cells from capturing solar power, so be sure to keep them clear.

Q. "What is a Maxi-Filtra?"
A. 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.

Q. "Can the Maxi-Filtra be installed in an existing system?"
A. Yes, the Maxi-Filtra can be retro-fitted on an existing system.

Q. "Does the Maxi-Filtra require maintenance?"
A. No maintenance is required other than replacing the cartridge.
