Vetus NSF25 - Odour filter with 25mm (1") hose connection Perko 25 / 387 Depth in/mmEach waste water tank requires an air breather line, through which unpleasant odours may escape. This can be prevented by installing a VETUS no smell filter into the breather line. The no smell filter element contains a special odour absorbing material. The filter can be installed very easily. Model NSF25 is suitable for a 25mm diameter breather hose. The filter element is exchangeable and should be renewed once a year.
