Fellow Prismo AeroPress® Coffee Brewer Attachment


Looking to take your AeroPress® coffee brewer to the next level? The Prismo coffee brewer attachment is going to get you there. Unlock espresso-style coffee without lugging around a full-blown machine. Countless prototypes were created before Fellow landed on a final iteration that could create enough pressure for an espresso. The no-drip seal allows for full immersion brewing resulting in a syrupy, full-bodied one, two coffee punch.

What’s the secret sauce?

  • Pressure Actuated Valve “pulls a shot” with more pressure. The specialized valve seals until you press down, creating built-up intense pressure.
  • No Drip Seal lets you ditch the flip. Brew a full immersion method without inverting your AeroPress®.
  • Reusable Etched Metal Filter filters out the grit. The 70 micron etched fine metal filter stops sludge from creeping into your cup.

PRO TIP: The Prismo attachment can also make a mean coffee concentrate.


  • Designed in San Francisco, California
  • Polypropylene body
  • Silicone valve
  • Fits with AeroPress® Coffee Maker
  • 2.75” H X 2.75” W X 1” D

WorKs perfectly with aeropRess

One thing to note is that it does not work with the Aeropress Go, it doesn’t fit. But if you have a regular Aeropress, it works perfectly and the espresso-like shots produced are very good!

It works great!!!

I have used some other washable filters and so on over the years for my aeropress and they seemed to work descent. This attachment is by far the best I have ever used. I’ll use it 100% of the time now on mine “espresso or not” . Very nice product!!

Excellent product

I've been doing the inverted brew method with a metal filter for a long time with my Aeropress, and I love that I can brew it traditionally and quickly with the Prismo attachment. There's no sludge in my mug, and it tastes great!

Nice ADDITION to the aeropress

Saves me a second paper filter when brewing and doesn't dribble. Doesn't really do "espresso" but it's nice to have a way to brew a concentrate without doing the potentially disastrous inverted brew method. Makes a fun sound too.

New year essentials

Arrived exactly as expected, coffee making is now made much more efficiently. Heads up I’m a one man team, and it works great for me...I think I would be annoyed if I had to make two cups in the morning...but somethings are worth it

I had no idea that instant coffee (decaf, nonetheless!) Could taste excellent!!
