If you use your Aeropress daily, check out the S Filter from Kaffeologie -- it's a mesh filter. It allows for more oil to come through instead being absorbed by the paper. I find it's best with an inverted process, but that's personal preference.

The filter is pricey for what it is, but it does have a lifetime warranty.
