Prismo AeroPress Filter Attachment, No-Drip Espresso-Style Valve

Brilliant add on for the Aeropress makes it an even better brewer, can't say for the espresso shots as I've still to try that but I've brewed it and got some cream and and added water to make a lovely americano style drinks very handy and versatile

While it might seem expensive for what is essentially a plastic cap, a metal screen, and a pressure valve (similar to a ketchup bottle), the Fellow Prismo is an great upgrade for the Aeropress. Crucially, it offers much better value than Aeropress's own official Flow Control cap while doing the exact same job. Its main purpose is to stop water from dripping through the filter before you press the plunger, allowing for a full immersion brew without the disaster risk of the "inverted method." It works perfectly for this. It fits my Aeropress Clear perfectly, though required a bit more force that the regular cap to screw on tightly due to the rubber seal. It's also easy to clean after, I just rinse it down and let it dry. It also adds some versatility to your filtering options: you can use just the included metal filter for a fuller body, but I personally use it with a paper filter on top to get a much cleaner cup. It handles both easily. Despite the initial price, I use it every single time I brew, making it definitely worth the investment.

It’s a great addition to the aeropress. I’ve used metal fillers for a while and found the fellow a smoother method. It’s simple, clean and creates really nice espresso style coffee. It’s easier to plunge as well. A few people have written complaining about the metal filter making the coffee taste oily. If you have a traditional espresso you get the oils in the cup so I don’t see the problem. If you’re after a clean cup then use a paper filter or whip out your v60. It’s nice to have this as an option when I want something more espresso like. I can’t stress the ‘like’ enough. If you want proper espresso then buy a machine. This is an espresso like variation on your aeropress. Would recommend to all those with an open mind.

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.

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.

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

If you are an aeropress consumer, this is an interesting gadget to have. For the life of me, I can't really get that espresso like cuppa from this. Maybe I am not grinding the coffee fine enough. But then, I don't have a £200 grinder to get that done. With the regular aeropress grind, this contraption spouts out regular aeropress based coffee, with the oils passed through as you'd expect with metal filters. Where it does add value, however, is in the fact that you no longer need to flip the aeropress, the way most (at least I) do with paper filters to avoid non-extracted water passing through. In fact, you better NOT do it with this, because if you try those shenanigans, it will soak you with a jet of coffee from that valve, because of the initial bit of pressure in the aerorpress container. Also, the metal filter of this thing is a lot finer than regular metal filters, so the oils get through, but there's no fine particles at all. That's a plus. So I do use it every now and then to change up my coffee when I feel like it. But considering that I prefer paper filter aeropress, I could have lived without it. Also, it's a little bit more hassle to clean this compared to paper filters, which I reuse btw for a few times. Or maybe I haven't quite nailed my workflow because I don't use it as much? Okish device then. Claims things I don't think it achieves. But still does give a good cup of coffee when called upon.

I've been thinking of buying one of these for a long time. There are many ways to use the Aeropress but I like to make a 65 gram shot with 20 grams of coffee. Then I add frothed milk. For darker roasts, that's quite straightforward, but with lighter ones, you don't get all the flavour you can out of the beans. You can, of course, invert the tube but when you revert it before pressing the coffee bed doesn't lie flat. This, way - despite leaving the coffee and water in the tube with a three-minute wait - there is no early leakage through. All the coffee gains the flavour. Not only does the coffee taste great - I enjoy the coffee oils that are usually filtered out via a paper filter. The downside is - for a bit of plastic - the Aeropress and its accessories are ridiculously overpriced these days as they continue to try and over-monetize the brand. But the coffee tastes great at least.

エアロプレス初心者には助かる商品です。浅煎りで細かく挽いた時にデフォルトの商品だと天地返しで横穴からの液漏れ（微粉漏れ）が気になりましたが、こちらの商品を使うと微粉漏れが減りました。紙フィルターも間に挟んでいるので油分もしっかり除去出来るので好きなコーヒーに近づきました。

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.
