The Studor Maxi-Filtra is a robust two-way vent that eliminates bad odors with a sturdy filter designed specifically for outdoor drainage applications. It contains a replaceable active carbon filter that operates as a two-way vent, filtering air in both directions. Its robust design means the Maxi-Filtra can be used vertically or horizontally and can be installed in hard-to-reach places. For use externally, it operates as a 2-way vent, filtering air in both directions. Particularly for use with septic tanks, the Maxi-Filtra may also be installed on open vents already existing or for new buildings where regulations insist on their inclusion within the building's drainage system. For best results, the Studor Maxi-Filtra should be installed with Studor Air Admittance Valves (AAVs). Fits 3- or 4-inch connections. Dimensions: 5.25-inch vent height x 4.875-inch vent diameter. ABS construction. Includes 4-inch rubber gasket.

This filter arrived late and missed the plumber who just came today after the window to return closed yesterday and it is not the piece that was described and doesn't fit my pipe. I'm so bummed, may I please return? Hello? Customer service?

It was fine and easy. We are fairly mechanical inclined. So no problems there. Does it’s job. But those not so adept could use directions either on or in the box.

Had a new tank and soak away install but have been getting an eggy smell the closer to the vent you were, had the tank inspected and it is working fine so the smell was nothing to worry about in that regard but it was off putting when in the garden, after installing this to the top of the vent the smell has gone and has not yet returned - took 5 mins to install and the results were immediate, would definitely recommend if anyone has similar vent smell - do get it checked before hand though as smells can be in indicator of potential issue 👍

Our vacation home has a septic lift station next to it - right near our deck. Sometimes the smell coming from the vent is just too much. We finally broke down and spent the $65 for this filter. Works as advertised. The smell is gone. Well worth the money.

This small, discreet yet very well designed product is a nose saver. We have a 39’ park model 5th wheel and put this in our main line clean out it made the biggest difference no more smells. If you own a bumper pull, gooseneck, or 5th wheel trailer and park it for the year hooked up or just glamping either way if there is a sewer clean out get this. The smell will be gone in an hour or 2, the only thing you will smell is what was lofting in the air before the install of this carbon filter. I honestly did not have high hopes for this but my expectations were exceeded with the quality and performance of this product.

Effective solution for septic system emissions, some jurisdictions require a carbon filter vent to treat noxious emissions from septic system, highly recommended, solved my emissions issues and it'll solve yours, easy to install, pricey but worth it.

Purchased this in December 2015. I've had it installed a little over 2 years now. We had an awful time with sewer gas smell on cold mornings ever since having our sewer main replaced. This has made a huge improvement. I haven't changed the filter in 2 years, and it still seems to be working. The filter cartridge is tiny, and the activated carbon inside has to have long since stopped working. I think the device really only restricts air flow imho. That said, it does a great job.
