Installation & Troubleshooting
BEFORE installing your Odorhog.
Right out of the box, tap the unit firmly, up and down on a solid surface. This will fully seat the carbon bag inside the cavity. OdorHogs are shipped horizontally (fully assembled for your convenience) and during transit, the mesh carbon bag occasionally shifts inside the body of the filter, which would allow odors to escape, sneaking up the inside of the body of the filter.
Installing a Mushroom Cap, Metal Cap, or AeroHog 360 Filter.
- Plastic slip on cuffs require no glue or tools. Snug it on and give it a twist.
- Clamp-on units require a 5/16” nut driver or a flat head screwdriver, either will work. Slide the rubber coupling over your vent pipe. For more tips, please see below in our troubleshooting section.
Installing an In-line Filter
Measure the length of your filter. Take that measurement and subtract two inches. This will be the length of pipe to remove from your vent pipe. Either end can be facing up or down. Do not remove the belt clamps closest to the center, as they hold a screen in place that secures the carbon filter. Mark the vent pipe with a marker. Use a hack saw or similar saw to remove the section of pipe. Loosen the belt clamps closest to the ends and slip one end of the in-line filter over the vent pipe. Slip the other end of the filter over the other section of pipe. This will give you one inch of pipe on both ends in which to tighten the belt clamps. Tighten both ends of the filter snugly. Rubber couplings are flexible when warm.
Installing and Starting the PowerHog Solar Filter
You have purchased a very unique, solar powered air exchanger with a NI-MH rechargeable battery. The battery should initially be charged with 16 to 20 hours of sunlight*. The fan has been tested prior to shipping. The fan switch is now in the off position. You must turn the fan’s toggle switch to the on position before installing on your vent pipe.
The toggle switch is located under the fan blade. Slip the loosened rubber coupling and fan assembly off the top of the unit, then turn the fan switch on (you can use a pencil eraser to turn it on if difficult to reach).
Once turned on, secure the fan and rubber coupling back onto the top of the OdorHog filter and tighten the stainless steel clamp. Keep in mind that rubber couplings are more flexible to work with at warmer temperatures. Your PowerHog is now ready to attach to your vent pipe.
*Even though the solar battery is charged when shipped, it will discharge during shipping. Place the unit in direct sunlight and allow the unit to charge prior to turning the toggle switch on per the instructions. Without charging the unit, the battery will not have the initial charge to run the solar fan all night.
Tips on using your PowerHog Product:
Be sure your installation is in a sunny location to get the best performance out of your solar fan. To increase the exhaust rate of the air leaving your vent, you can remove a portion of the carbon from the unit. To do this, remove the solar fan and coupling on the top of the unit. Then remove the carbon bag and snip the top off the bag, pouring ½ the carbon directly into the body of the OdorHog. This will allow better air flow if needed. Reserve the remaining carbon for later use. Moisture/condensation under the lens of the solar fan is not a cause for concern. It evaporates and does not affect the performance of your fan.
Still smelling odor after the installation and it’s coming from the vent pipe?
- If you’ve already tapped the unit firmly (up and down motion) and smell odor from the vent pipe and the OdorHog after installation, remove the cap on the filter and pull the carbon bag out by the handle. Snip the top off the carbon bag. Pour the carbon directly into the filter, then replace the cap. This should resolve the issue.
- If you are experiencing odor inside the building after installation, the restriction from the densely packed carbon should be lessened. Remove the cap on the filter and snip the top off the bag. Pour ½ of the carbon directly into the body of the filter (reserve the other half for later use), then replace the cap. This should resolve the issue. If it does not, email Info@OdorHog.com for assistance.
Tips for Rubber Couplings
- When you are ready to install your OdorHogs on the vent pipes, warm up the rubber by setting them in the sun for a few minutes prior to installation. This will make them more flexible to work with.
- If you have a pipe that has a slightly larger measurement than your OdorHog, it's best to remove the bottom stainless steel clamp completely and put it over the vent pipe. You will be able to snug the rubber lip over the vent pipe, then secure it with the stainless steel clamp.
- A screwdriver will loosen and tighten the clamps, however a 5/16" nut driver makes the install process even smoother.

Accessing the carbon bags
OdorHog carbon bags can be replaced while the filter remains on the vent stack.
- Mushroom caps have 3 screws –unscrew them ½ way out and then lift the top off.
- Metal caps should be gently shimmied back and forth to lift off. No tools are required.
- Aero caps (360 Rain Cap) should be pulled directly off. The 1.5”, 2” and 3” units can be tugged on firmly to pull off. The injection molded AeroCap is rugged and will not crack or break under these conditions. The 4” unit is larger and the cap fits down inside the top of the body and small dabs of silicone are at the back edge to hold in place. Use a box cutter or other sharp edge to cut the silicone and then pull the Aero cap directly out.
- In-Line Units: Loosen the upper belt clamps with a 5/16” nut driver and slide the rubber coupling up onto the vent pipe.
Replacing the carbon bag
The used carbon bag can be pulled out by the zip tie handle and disposed of. Be sure to wear disposable gloves.
- Hold the new carbon bag upside-down, (the zip tie handle is temporarily at the bottom of the bag).
- Pinch the bag together at the top, allowing the carbon to shift to toward the zip tie. This will cause the bag to become narrow on one end.
- Flip the bag upright and insert the narrow end into the OdorHog. It may take some slight massaging and shifting of the carbon inside the bag, to fully fill the cavity. The zip tie should now be on the top, so it can be pulled out when you change out the carbon bag next time.
- Make sure the bag is fully seated in the cavity so gases must pass through the carbon instead of sneaking up the side of the body of the filter.
Reinstalling the filter cap
- Mushroom Cap: Screw the mushroom cap back on. Additional holes in the body will not cause any issues with performance.
- Metal Cap: Push the metal cap back on using a towel or flat handed so it does not bend the metal cap. A gentle side to side motion will secure the cap back in place.
- Aero cap (360 Rain Cap): The 1.5”, 2” and 3” AeroHogs should have the cap tapped back onto the top of the unit with a rubber mallet (use a shop towel to cover the Aero cap), then tap the cap onto the body of the AeroHog. The 4” AeroHog should be pushed back inside the top of the unit, then secure with a dab of silicone.
- In-Line Units: After the new bag is installed, tighten down the new bag’s zip tie, or place a new zip tie further down on the unit to force the charcoal to become fully seated inside the cavity. Slide the rubber coupling down the pipe, onto the filter and secure the stainless steel bands with a 5/16” nut driver.
If you smell odor coming from the vent pipe and filter after the carbon change, remove the OdorHog and tap it firmly several times (using and up and down motion) to fully seat the carbon in the unit. Then reinstall onto the vent pipe.
PowerHog Carbon Changeout Instructions
- Remove the "solar fan assembly" from the top of the unit (the solar fan and rubber coupling). Use a screwdriver to loosen the rubber coupling from the pipe body of the PowerHog (a 5/16" nut driver also works well to turn the nut on the clamp).
- Do not disassemble the fan itself, it should never need to be taken apart.
- Do not remove the smaller rubber coupling on the bottom of the PowerHog, it needs to stay secure on the unit at all times.
AeroHog 360 Carbon Replacement Tips
- AeroHog carbon change outs are easy, and can be completed while the unit remains on the vent stack.
- The 1.5”, 2” and 3” AeroHog Cap can be removed by grabbing the cap and giving it a strong pull upward.
- The 4” AeroHog Cap can be removed by slicing the small bit of clear silicone at the back side of the unit, where the cap meets the top lip of the body (with a box cutter or knife).
- Replace the 1.5”, 2” and 3” AeroHog Caps by keeping the cap centered on the top of the filter body while you tap it on with a rubber mallet. The rain cap is injection molded and extremely sturdy, do not be concerned about breaking it with the mallet. You can also cover the lid with a shop towel for balance when tapping the lid on (optional).
- Replace the 4” AeroHog Cap by fitting it back down inside the top of the body of the 4” filter, then secure with a dab of silicone on the back side of the unit. You may need to bevel or sand down the outside, bottom edge of the cap if there is any plastic flash that may impede the cap from settling inside.
