The first Vacuum pot I ever owned was a Bodum Santos like in reply #40. It had one of the best filter systems I’ve come across, in fact, after I got rid of the machine, I still kept using the nylon filter disk on my first Sunbeam C30, with the frame that held the cloth filter, and it worked great in this application.
The Bodum Santos made very rich tasting coffee, but the beef I had with it was the draw down happened too quickly, not giving the brew enough time to remain in contact with the ground coffee. Therefore, in order to achieve a good, strong brew, I needed to use double the ground coffee I normally used. So this made it a no go for me. It was also hard to keep clean and the plastic scratched easily, giving it a cloudy appearance.
