If using a filter, does this mean you can vent inside the boat?

I assume you are talking about the holding tank vent? If so, do not
even think about venting inside the boat. The odor will knock you
over and render the boat uninhabitable.

If not
why filter?

Are these filters effective or do they cause more odors to form?

The idea is to minimize the odor outside the boat. The jury is still
out on whether that is a good idea or not because the filter will
reduce the flow of air to and from the tank.

You should really read Peggie Hall's book on this subject or do a
search on Google for some of her past postings:

http://www.amazon.com/Get-Rid-Boat-Odors-Aggravation/dp/1892399156/ref=sr_1_1?ie=UTF8&s=books&qid=1260040017&sr=1-1

Let me explain the filter I'm talking about.

This filter supposedly stops odor so why not vent inside?
BTW I have Peggy's book.

It will lead to problems sooner or later. Peggie is a big advocate
of freely venting the holding tank with lots of fresh air. At the
very least, the filter will impede that venting. At worst the filter
will become clogged sooner or later and cause the tank to pressurize.
Use your imagination on where that will lead.

Perhaps I miss-remember Peggy's advice but I have the distinct memory
that Peggy suggested large holding tank vents and felt that a supply
of oxygen was necessary - I seem to remember 1 inch vents?. I can't
see that adding a charcoal filter to the system is going to cause
troubles assuming that it doesn't impede air flow but why vent inside
the boat - what advantage is that going to give you?

Disadvantage. Better venting due to increased airflow outside.
Time to rant.
First, I don't have a boat, but so what?
When I get a boat, it will have an Airhead or equivalent.
Every owner account I've read has been a good review.
Not suitable for "party boats" or more than 4-5 crew, but for a couple
or a couple with a couple kids it's fine.
No holding tanks, hoses, valves, pumpouts, etc.
And no stink.
Only reason I can figure they aren't more used is simple ignorance,
and the marine head parts industry poo-pooing the idea.
Rant over.

What is an "airhead"? I've only ever heard that term used in reference
to ditzy blonds..."she's an air head".

Plug airhead marine toilet into a google search.
You'll find info and comments by those who are using them.

It's a composting toilet at an insanely inflated price ($1K!) that
doesn't out-perform a $79 porta-potty in actual use.

I'm not a real aficionado of marine toilets at any time but a thousand
dollars to take a crap?

The temperature is dropping like a barrel over Niagra Falls today.
Supposed to be 21 at noon today and hold for a few.

Since this is the first boat I've ever had that has plumbing I'm
kind of nervous about all that plumbing freezing up.
So the last few days have been spent digging through her bowels
trying to get all the lines emptied.

I'd almost (today) prefer a cedar bucket.

I may feel different about that in April though.

Hehe. You didn't price in the TP.
There's similar toilets that cost a couple hundred less.
For installation of a first head, the premium comes down when you
subtract what the cost of a common marine head, holding tank, etc
would be.
But some of the owners say they have replaced functioning marine
head systems with the Airhead. Gets them space, and they can close
off thruhulls. And no more pumpouts.
Different strokes. I kind of like the idea myself.
Easy when you don't have a boat.

Ever been on a small boat with one of those. They do STINK. I'm not
kidding. It's like being in a poorly maintained horse stall.

The manufacturer mentions this deftly, so they can say you have been
warned. From their brochu

"In many cases a noticeable improvement in air quality will be
perceived upon opening the companionway hatch after lay-ups."

And you will not find many marinas that welcome folks dumping these
things into a standard commode as the manufacturer suggests.

A 6 gallon Porta Potty is just as good a solution, and costs less than
1/10th the money. The Porta Potty can either be carried ashore and
dumped in a standard commode if you can find a place that doesn't
mind, or pumped out by any conventional pumpout rig.

The holding tank for a Porta Potty remains completely sealed when you
disconnect it, so carrying a second tank on long trips is feasible.
