Can a septic tank filter be used with the Enviro-Septic® Technology?

Yes, however, effluent filters are not recommended by Presby Environmental, due to their tendency to cut off the essential oxygen supply (even when they are properly installed and maintained). If you are required by the state or local authority to use an effluent filter in a gravity fed system, the effluent filter selected must allow the free passage of air to ensure the proper functioning of the system. If a filter is used, follow the manufacturer’s maintenance instructions and inspect filters regularly.
