The Studor Maxi-Filtra is a very sturdy filter designed specifically for outdoor applications to eliminate bad odours. Its robust design means the Maxi-Filtra can be used vertically or horizontally and can be installed in hard-to-reach places.
The active carbon filter operates as a two-way vent, filtering air in both directions and is packaged in a very resilient exterior for longevity, with a replaceable filter.
Particularly used on the ventilation pipe of septic tanks, the Maxi-Filtra may be installed when the odour from existing vents is a problem, or when vents are to be included in the drainage system of a new build.
Other installation locations may include water tanks and silos, where an active carbon vent is required to prevent a vacuum. Here an airflow rate of up to 5 litres per second can be accommodated with a 100mm diameter pipe.

For best results, the Maxi-Filtra should always be installed in conjunction with Studor Air Admittance Valves (AAVs) throughout the drainage system and we recommend that the filter should be replaced at least every two years.
Occasionally, to eliminate the bad odours from drainage vent stacks, a Maxi-Filtra can also be used.
To ensure the correct function of the drainage system (subject to local regulations) we recommend that the Maxi-Filtra is fitted in conjunction with a Maxi-Vent. See below for an example of this type of installation.
