Prismo Attachment for AeroPress Coffee Maker - Enhance Your Manual Coffee Maker to Brew Espresso-Style and No-Drip Immersion Coffees, Reusable Metal Filter

As far as overpriced coffee widgets go, this one is pretty cheap. It also makes a meaningful difference to the function of the Aeropress, and I can’t imagine not having one now. I use it for making espresso-strength shots with both the metal filter and a paper filter fitted. It gets used two or three times daily. The coffee through this tastes closer to espresso than the stock Aeropress (which tastes like super-strength filter coffee to me). It is just as easy to clean the Prismo as it is to clean the standard Aeropress gubbins, as long as you use a reasonable amount of pressure to compress the grounds into a puck. It also helps if you use both metal and paper filters. Basically, the Prismo seems fine with a quick rinse along with the rest of the Aeropress. I have not had it leak coffee and, for now, I feel confident pouring water into the Aeropress without a mug underneath it as long as the Prismo is fitted. So why is it overpriced? Well, it’s basically the rubber valve out of a ketchup bottle that’s fitted to an adaptor, allowing you to stick it to the bottom of the Aeropress. Oh, and a reusable filter, which softens the blow a little. As it’s based around a valve that everyone else uses as a disposable part, I have very limited hope for its lifespan. You can, of course, not get spares and Fellow who will offer a two year warranty on a kettle won’t offer you a day on this (but that’s in the UK - they’ll give you a year if you’re in the US). I’ll update and apologise if it lasts a reasonable length of time.

I bought this for my partner who has the aeropress and he’s been really liking it. We’re not entirely sure if it actually gives a different flavour or crema but it’s easy to use and leak-proof. The small knob on top may be easy to lose but with regular careful care we’ve been fine. Good quality, fine filter that works well

The Fellow Prismo Attachment for AeroPress is an excellent product. Bought on the recommendation of a friend, it does a great job of making the AeroPress easier to use, and ensuring a consistently good coffee is the result. It’s also super easy to rinse clean, and has worked well for months now.

I was doubtful about the claims of 'espresso style', and I was right. I'm sure this could be improved allowing a better pressure buildup like my little manual portable espresso device, but this filter just won't get close. HOWEVER, this is the only negative thing I'd say about it. This is what the Aeropress should have been like to start with: it seals the cylinder perfectly, no spills, no mess, no silly inversion needed. For that reason alone, this filter is well worth it. I've experimented a bit with different grind coarseness, water temperatures and amounts, brewing times, and there's a nice range of flavours one can get with this, worth experimenting a bit to get the style you prefer. I find the coffee is a bit more aromatic and perhaps sweeter too than when using the original attachment with paper filters, presumably due to oils otherwise stuck to the paper? In short: it makes the Aeropress a lot better to use. It's easier and cleaner. Just don't expect anything close to espresso, but that doesn't mean you cannot get a good coffee.

This attachment allows me to make my aeropress coffee by the "inverted" method without having to actually invert the device and risk all the usual instability hazards, which is great in our campervan. The metal filter is OK, but I still continue to use paper filters as well. The resulting coffee tastes amazing. Clean up is no harder than it is with the original end piece. If you loosen the filter from the aeropress and slightly withdraw the plunger, you can then remove the filter and cap and expel the grounds in a satisfying puck just as with the original set up. I was very worried that it would be hard to remove after reading all the reviews that said it was very tight fitting to the aeropress, but it is not. It goes on and off perfectly, and I wonder if those other reviewers had a different aeropress model, perhaps slightly smaller than the original version. The only downside to this item is the cost, which seems bonkers for such a small bit of kit, but it looks like it is going to last, and for that reason it fully deserves my 5 star rating.

Essentially, this is just an add on cap to the Aeropress that lets you make better espresso style coffee. You get a cap that screws onto the Aeropress and a metal reusable filter. The cap has a pressure valve that ensures the water only passes through the coffee, through the filter, into the cup when you apply enough pressure with the plunger, unlike the cap that comes with the Aeropress which requires little pressure for the water to pass through. With the Prismo you’re encouraged to press the plunger harder than with the original cap so as to create higher pressure. Given that espressos are made when water passes through coffee at high pressure, this means the Prismo produces coffee that is more like a genuine espresso than the standard cap does. It’s not 100% espresso but it’s as near as damnit! It’s certainly more than acceptable if you don’t have an espresso machine handy. It’s a very worthwhile add-on to the Aeropress, I normally use mine to produce the coffee for lattes - my favourite style of coffee, or for the quick hit of caffeine an espresso supplies. Two thumbs up 👍🏻👍🏻

Use this every day. Easy to clean, no drips. Excellent.

Niquel pour sortir un petit expresso de son Aeropress. On est pas sur un équivalent de machine italienne non plus, mai ça change un peu donc je recommande pour l'expérience

I have made coffee with this a couple of time , and it pulls a very good shot of espresso every time, however I use a paper filter along with it, otherwise I will get grounds in my coffee. I will recommend this attachment to every espresso lover ,who have aeropress

In addition to eliminating the need for paper filters and using the inverted method, the taste is in my opinion also slightly improved. Highly recommend! Can not say anything about the longevity of the product as I only had it for a few days. Update: After hundreds of coffees brewed, it still works like a charm. The metal sieve started to bend and deform very slightly under all the pressure and heat. Still completely usable though! Great product.

Overall it is great attachment especially if you like espresso style coffee. The only annoying thing is that putting a stable plunger in means very little amount of water might still escape to the cup. But it still is a huge improvement over original cap. You also get the metal filter that works quite ok and reusable.

Este tipo de porta filtro com válvula devia ser incluído como equipamento standard. Não faz qualquer " crema ", aliás a força para empurrar o êmbolo é menor do que a usada com o adaptador normal e filtros de papel. Para quem espera fazer um expresso, esqueça, não compre. Comprei para evitar o método invertido. Enquanto não se coloca o êmbolo, não cai uma pinga de café. Não funciona com os filtros de papel, pois o café sai pelas bordas laterais do porta filtro. Excelente qualidade da Fellow ( a minha cafeteira de aquecer a água também é Fellow ). É porém um pouco caro. Recomendo
