If the breather outlet of the waste water tank is positioned outside the boat, some nasty fumes and odours may be vented to outside as well, which may be annoying for you and for your neighbours in port.
The Craftsman Marine no-smell filter offers the most adequate solution. With the filter connected to the breather system of the tank, all unwanted odours are literally “arrested” inside.
The filters can be installed easily onto the breather hose, which is available in different diameters.
