Hey, Carla, I just got something I really like, and wanted to tell you about it: A stainless-steel mesh filter for Aeropress! It replaces paper filters and lasts forever! Or for a long time? Remains to be seen.

It lets the liquid flow through a little faster, so it's best to use it with the upside-down Aeropress - you're doing that already, right? The exchange is that you get more of the essential coffee aroma oils that paper traps, on the good side. On the other side, it lets through just a little very fine sediment, but not nearly as much as a French press. Also, it's microscopically thicker than paper, so you probably won't be able to screw the filter all the way down, but with mine, as long as I tighten it as much as I can, it seems to work fine. Coffee tastes a little better to me, so, highly recommended!
There are about three different models with different mesh fineness, but this one is supposed to be best for espresso or drip grind. It's only $8.99, so what can you lose?
