Benefits of Cleanawater passive & sewer vent filters

  • Up to 99.5% odour removal
  • Can connect to external vent duct or stack
  • Allows air inflow into sewer system
  • Greater customisation with multi-cartridge options
  • Simple installation for quick setup
  • Replaceable cartridges for a solution that lasts

How it works

Passive vent filters work using cartridges full of high performance activated carbon to absorb and oxidise sewer gases. Low back pressure in the units encourages airflow. Passive vent filters can be used to treat H₂S, as well as dimethyl sulphide, mercaptans and volatile organic compounds (VOCs).

Benefits to clients

Passive vent filters are specially designed to require very little maintenance, with no moving parts. As a result, they are robust, securely assembled and appropriate for harsh environments.

With easy installation and a high odour removal rate of 99.5%, passive vent filters offer a low cost, long-term odour management intervention. Replaceable cartridges make equipment upkeep a breeze.
