Aeropress metal filters, are they worth it? I was wondering (other than the long term saving of not having to buy paper filters), what are the advantages of using a metal filter such as this?

In the copy is states:


  Fuller body cup of coffee


But is this something the average Joe would notice or is it marketing spiel?

My main thought would be you would get less of a papery taste, but after rinsing the filter, I can;t say that I've ever noticed the taste of paper from a filter (maybe if I had did an A/B test between the 2 I would?).

Would like to hear any thoughts from people that have one?
I have used both the paper filters and the "Able" brand metal AeroPress disk that you linked. They are a bit different, and I use both the metal disk and paper filter based on my mood. To my taste, the metal disk does produce a "fuller" bodied cup (because more "stuff" comes through the filter -- oils and macro-particles or whatever). I believe that "an average user" (by my definition) would be able to tell the difference in a side-by-side test, and probably enough to determine preference.

That said, I prefer the paper for a few reasons.

First, the simple convenience is better for me. After brewing, I plunge the filter and spent grounds directly into my compost container. After a quick rinse of the unit, it's clean enough for me.

As for my (personal) taste and preferences, I think the paper produces a better quality and more enjoyable cup. Since the perforations are larger, there is more grit in the output when using the metal disk, so you end up with a (small amount) of "sludge" in the bottom of your cup, and it will turn bitter more quickly because of longer contact with the grounds after brewing.

As an aside, I also prefer it for the marginal (and debatable) "health" reasons. Paper filters remove some compounds (such as cafestol) that have purported cholesterol-affecting properties. For more of "my opinion" on that, see this question about general comparison between paper and re-usable filters and my answer about the topic in general.
