I make cold-brew coffee sometimes, which also lessens the acidity of coffee (supposedly by 67% or so.) It is especially good if you ever make iced/frozen coffee drinks, because you can adjust the concentrate ratio and get a much richer taste as cold coffees go. I also like the Aeropress, but my wife prefers the cold-brew method so we probably do that more often. We're trying to cut down on both, though.
I recently read a couple of studies that say that unfiltered coffee increased your risk of heart disease, because the diterpenes raise your serum concentrations of cholesterol, triacylglycerols, and alanine aminotransferase.
Sure, I use a 3-cup Chemex daily. It's great - the brew is consistently high-quality, and it's so easy to clean. You just toss out the filter and rinse the carafe clean, done in 4 seconds.
The Chemex filters tend to mellow the taste (not the caffeine) of the coffee out just a bit compared to a french press, but I personally like that aspect.
