I plan on conditioning for 3-4 weeks. I said the same thing to my wife. Clean up was longer than kegging. As for the filter, yes all gravity fed. I use this set up attached to the faucet for my brew water also. The base unscrews and you change the filter. I have taste and sediment filters. This is the second time I have brewed with it and could tell the difference in taste. As far as this set up, it is a 5 micron sediment filter. I bought it at the local plumbing supply store where I have an account. I don't remember cost but it was not much. A few PEX plumbing fittings and some clamps and you are in business.
