Am installing a new sanitary system and am curious about vent filters.
If using a filter, does this mean you can vent inside the boat? If not
why filter?
Are these filters effective or do they cause more odors to form?
Thanks

Hopefully all vents are located to minimise the risk of offensive odours
in the cockpit or below while under way, at anchor or moored by the bow.

Unfortunately most boats are kept in marinas most of the time and the
odour may well be offensive to neighbours and with the boat not free to
swing, it may well be offensive on board.

Feel free to vent below decks if you earn your living at the waste
treatment plant or driving a honey wagon and never want to take guests
or entertain.

Effectiveness will never be 100% and without a rigorous maintenance
program may be minimal, while any restriction on tank ventilation will
aggravate the root cause of the problem, risking increased odour and
other problems.
