Studor 20297 Maxi-Filtra Septic Tank Drain Vent Two-Way Active Carbon Filter, 3- or 4-Inch Connection

The vent pipe from our sewer system often ruined our back yard experience. Once this filter was installed, no more stinky smells! With the removal of the rubber section on the bottom, this was a perfect fit for our septic vent pipe and was easy to install. Works perfectly!

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.

Simple and effective. We had a recurring smell in the yard that we could not figure out. The septic system was new and the smell was a mystery. After searching online I came across this and decided to try it out. The smell was gone immediately.

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.

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.

I bought this for an aerated septic tank. There was no filter on the vent pipe, and I was tired of the smell. After only a week or two, I realized this filter was making absolutely no difference. The same sewer smell was back, and a sniff test proved that it was indeed coming straight from the filter. Yes, installation of the unit and cartridge was done perfectly. This product simply does not work at all. I sent it back for a refund, which Amazon honored.

Time will tell. Easy to install, but seems a bit pricey.

Muy bien empacado, se ve de buena calidad y llegó muy rápido

Je conseille fortement se produit dure très longtemps et très solide surtout quand on a un chien qui mange tout. Le produit fait super bien son job, aucune mauvaise odeur du coup le prix est correct.

Han desaparecido los olores prácticamente a la totalidad. Muy contenta. El recambio del filtro, cuál es?

Reçu rapidement et fait le job

Goed en naar verwachting

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 👍
