Notes on filters, gear & the cup in between
Snobcoffery is a small, independent reference on home-brewing gear — mostly the AeroPress and the filters that sit at the bottom of it. Every page is written from published material: manufacturer pages, peer-reviewed or university research, and coffee-trade reporting, each listed under “Sources”. Nothing here is a product test, and nothing is for sale.
The domain once hosted a personal brewing blog. This is a new project with no connection to that blog, its author or the domain’s previous owner (see About). A handful of old addresses on this domain are still linked from coffee sites around the web, so those addresses now carry fresh, sourced pages on the same topics.

Why filters get their own site
The AeroPress was unveiled in November 2005 by Alan Adler, a Stanford engineering lecturer best known for the Aerobie flying ring. It is a cylinder, a plunger and a screw-on cap that holds a small round filter — and that filter decides a lot about the cup. AeroPress’s own guidance says paper “removes those elements for a very clean cup”, while a metal disk “does not absorb oils or withhold fines” and so “increases the texture and body” of the brew.
That single swap is one of the cheapest experiments in home coffee. It changes body and clarity, and — according to research summarised by the Harvard T.H. Chan School of Public Health and a 2025 Uppsala University study — it also changes how much of the cholesterol-raising diterpenes cafestol and kahweol end up in the cup.
Quick reference
| Filter | What it holds back | Typical cup |
|---|---|---|
| AeroPress paper micro-filter | Oils and most fines | Clean, lighter body |
| Stainless steel disk (e.g. AeroPress metal, Able DISK) | Larger particles; holes on the AeroPress metal filter are 178 microns | Fuller body, more texture, some sediment |
| Two papers stacked | More of the above | Even lighter body |
Summarised from AeroPress’s published guidance; see the individual pages for sources.
