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

Expensive but does the job. No more odours from the septic tank

I’m impressed. We have lived in the countryside for more than a decade and at times have had to deal with the occasional whiff from the septic tank, especially if the washing machine is running. Eventually, I looked into how to reduce the smell and a carbon filter was recommended. Since it has been fitted, for over a week now, I have not smelt the septic tank once! The unit was very easy to fit and looking at how it went together, I imagine that the carbon filter part is very easy and simple to replace when the time arises. Very satisfied with my purchase.

Worked a treat getting rid of the smell from our septic tank.

Have fitted 2 to septic tank vents that have proved smelly in the past, seem to have done the job so very happy. Only issue is the usual internet purchase one, no proper VAT receipt for business use. Otherwise all good.

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 👍

We have had an overpowering stench from a septic tank since we moved into this property. We are the last in the line of a number of properties on a country estate. The smell was overpowering at times even if we were sitting in the garden you knew when someone had run waste water down the line. I fitted this filter and instantly the problem was cured. It was easy to fit and even when I was up the ladder on top of the vent pipe where the original cowl was fitted the smell was foul. The minute this new unit was fitted the smell disappeared. 100% recommend this unit if you have a similar problem

It simply works, had all sorts of experts reviewing the treatment plant all suggesting expensive fixes, £40 later it no longer smells. I noticed on a previous poor rating commented by one person he said it allowed the smell back into his house? We had our house plumbed in incorrectly and they fitted dergoes inside. We had to have them all taken out due too letting the odours into the bathrooms, major problem. This may of been his problem as well. Hope this helps him. Great product and a cheap fix. Would strongly recommend

Seems to work. Replaced old unit with this and smell disappeared.

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.

Reçu rapidement et fait le job

Goed en naar verwachting

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!
