seconding the paper filter. it perfectly fits my 3-cup pot. it slows down the process a little, I found, which means the pot gets hotter and burns a little.

I found that pouring out the coffee ASAP as it comes out -- like, let it run for a few seconds, pour, fill again, repeat until finished -- gets a better product. but you don't get any particulate, and the flavor is much smoother. not sure if it's raising the pressure significantly enough to impact extraction, but wouldn't be surprised if it can bump it up +0.5 BAR or more.
