Marketing InformationThe Studor Maxi-Filtra is a two-way vent designed for use with septic tanks and lift stations. This UV-rated, outdoor-only vent filters air in both directions and comes with a replaceable carbon filter to remove bad odors. The Maxi-Filtra, as part of the complete Studor System, eliminates sewer gases from entering buildings and polluting surrounding areas. It can also be used for buildings connected to a sewer line, but the Studor technical department must first be contacted to determine installation feasibility.
