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

It makes really strong and concentrated coffee that tastes great. I grind my beans pretty fine and let them brew for one minute before pushing the plunger in. Cleanup is super easy as it makes a nice puck that usually pops out all in one piece. Very easy to make americanos and iced lattes. Even if you never make espresso with it, the valve on it is worth it to not have to do the inverted method with the regular aeropress filter holder. And the metal filter works great and lets through barely any silt. They should make this for the Aeropress XL

I really appreciate using the Aeropress as my go-to brewer for both home and travel purposes. It's one of the simplest methods available, and I love how easy and forgiving it is to make a great cup of coffee. Unlike other brewing methods that require more technique and attention to detail, the Aeropress is a filtered immersion brew that's straightforward and forgiving. The one complaint I have had with my Aeropress, is the small volume paired with needing to use the plunger to hold the flow. If you brew inverted, you need to insert the plunger deeply enough to prevent leaks or it coming loose, which costs you ~20% of the volume of the brewer. If you brew regular, you push some of the water through the paper filter prematurely when putting the plunger on the top, and again cost yourself 10-20% of the volume at the top. The Prismo solves this problem. The little check valve in the Prismo means the coffee will not flow until the plunger is added and some pressure is applied to the brewer. I can confidently brew upright using nearly the entire volume of the Aeropress, knowing that it will not leak, and I can let the coffee steep until I'm ready to grab the plunger and push it through. I do have one gripe- and it's that the Prismo claims to make "espresso-style" coffee; I would say that's a bit of a stretch. You aren't getting anywhere near the pressure required to make proper espresso. You have none of the body or strength in an Aeropress brew that you get from a real espresso machine. The Prismo is not for making "espresso", but I think the savings on paper filters, the ease of cleaning, and the enhancements to the workflow of using the Aeropress are valuable enough to justify the price without needing to make that stretch. I would absolutely recommend the Prismo as a great quality-of-life improvement for anyone who loves their Aeropress for its simplicity, convenience, and forgiving brewing.

One of my roommates bought one of the prismo attachments at our old house and I used it for a year. When I moved out, I tried to use the normal aeropress filter for a week, and ended up caving & buying a prismo because I love this thing so much. If you’re a big aeropress user this is a must. See below for my cons and pros. Cons: PRICE! Although I think it’s totally worth the money, this costs the same amount as the actual Aeropress. I get it’s a small company, but I would have liked to have paid $15, maybe $20 max for this. Fit. I have had my Aeropress for 3 years and it’s an older model. I can’t fully lock in this attachment without man handling it (it appears to be slightly too large for the groove) and so if there’s a lot of pressure in the aeropress, it’ll start to bubble coffee out of the cracks. Not a huge deal and I’m sure it has to do with the age of my aeropress. PROS: No Mess!: unlike the normal aeropress filter attachment that always seems to cause a total mess (I hope it’s not just me??), you can actually sit the aeropress upright without a cup under it with the prismo attachment on and nothing will come out until you push down the aeropress plunger. Stronger espresso- like coffee: I add in the equivalent of a scoop and a half using the aeropress scoop of finely ground coffee into the aeropress and I fill the aeropress about halfway with water. Then I stir it, and wait a few minutes while I heat up oat milk and it makes a super good latte. I am sure a coffee snob would not agree with how I use this but I like strong coffee / espresso and this seems to work. It also tastes slightly less acidic maybe? Way cheaper than buying an espresso machine! Durable: I used the prismo along with three coffee-drinking roommates every day for a year and it still looked the same as day one after that period of time and still functioned great. Reusable Filter: awesome quality, reusable filter. I think aeropress should partner with this brand and offer this as an add on with the aeropress. Even if you get it just to make your coffee making process less messy or for the reusable filter, It’s a great product and despite the price, I would recommend!

Background: I've been using the Aeropress (AP) for 9 years, making at least 2 cups with it nearly every day (except when we are traveling). I've used the paper filters and several stainless filters, and now the Fellow Prismo. I put off purchasing this unit for a couple of years, because I had trouble justifying the price. But my last metal filter failed, so I thought I'd finally give it a shot. I will admit that I didn't want to like this product, and I expected to give it a try, find multiple faults with it, and eventually put it into permanent storage. Boy, I am glad to be wrong about that! Review: The Prismo wins hands-down as the best tasting version. After playing with it and experimenting for a few days, until I got the hang of it, I performed some side-by-side taste tests with all the filters mentioned above, using the same coffee, and there is really no comparison. The Prismo simply makes a better cup of coffee, and it does it with less coffee. I'm actually using about 25% less coffee with the Prismo, which means it will pay for itself pretty quickly. Yes, I'm able to produce a better, richer tasting coffee with the Prismo, using less coffee. Here's why: 1. Because the little nipple on the bottom prevents the liquid from draining out before you push on the plunger, the coffee gets to steep entirely submersed in liquid, without it draining out prematurely. I've experimented with many different grinds, and with any of the regular filters, there is just no way to prevent this. I refuse to use the inverted method, because that's just ridiculous; seriously. Anyway, in order to get the best flavor from the coffee, you MUST stir it GENTLY through the entire steeping process (I steep for 1 minute), which you cannot do using the inverted method. NOTE: Always use the plastic paddle that comes with the AP for stirring - NEVER, EVER USE A METAL SPOON FOR THIS. I gotta rip on the Fellow marketing folks on this - the video on the Fellow website shows a woman using a metal spoon to stir the coffee, and this is sure-fire way to destroy the metal screen/filter. Bad marketing - BAD GIRL! Fellow, you should really replace this video with one that demonstrates the correct way to do this (using the paddle). 2. The nipple creates back-pressure when pushing down on the plunger, and if you lift it up to let more air in, right before it comes in contact with the grinds, then plunge it all the way down, you get a really good blast of crema, which is simply impossible with any other filter. This is what really makes the difference, because my results taste EXACTLY like barista-quality espresso. Smooth, rich, creamy - YUM! 3. I'm able to use a much finer grind than with the other filters. My wife and I like our coffee pretty rich, and with the amount of coffee needed to get that really rich, full-bodied taste, I've had to resort to a medium-coarse grind. Otherwise, I just can't push the plunger down, no matter which other filter I've used. Even with the medium-coarse grind I have to bear down on it with all my 215 pound weight to get it to go down. With the Prismo, not only can I use a fine grind to get the most flavor out of them, but the plunger actually goes down with much less effort. Cleaning is a breeze. I do the same thing I've always done with metal filters: rinse it out on both sides, as well as the plastic cap, every day. People who are complaining about the unit getting gunked up are disgusting; it's because they don't even bother to rinse the thing off when they're done with it. I've been doing this for 7 years with my metal filters, and never had any build-up issues. Got a problem with it getting clogged? It's your fault, not Fellow's. The only other step that I do is: Every few days I clean out the filter, put it back on the AP, fill the AP with hot water, and plunge it through; do this a couple of times, and this process cleans out the nipple really well, so it doesn't get clogged up - ever. My one complaint about the unit, is that it's a challenge to separate the metal filter from the plastic cap when they are wet. The rubber gasket seals on so tightly that I have to turn it upside down and hit it pretty hard, and repeatedly against my other hand, to get it to pop out. I get why they did this - it's part of the engineering that makes it work so well. But if there is a way to improve this part without sacrificing results, it would be appreciated. Despite this challenge, I would definitely replace this unit if mine was lost or fell down the garbage disposal.

Benefits: Really high quality materials. I love really good, fresh, hand-ground and home brewed coffee, so I don’t try to make ghetto espresso with it (because I realize you can’t truly make espresso without pressure). I instead use it as a replacement for the original Aeropress paper filter system. This thing allows you to brew your coffee properly without using the inverted method because it won’t let liquid through until you push the plunger. Pushing the plunger is actually much EASIER with this than the original. The slightest pressure on the plunger opens the nozzle and coffee flows into your cup vs the large effort often required with the original cap and paper filter. It doesn’t leak past the sides when you press either. No mess, no inversion. Now add on top of those benefits that you can hear the coffee spraying out of the nozzle, which allows you to stop pressing when the liquid is gone, BEFORE you squeeze the acid out of the grounds into your coffee making it bitter. But wait.... there’s more!! You get the bean oils and the tiniest bit of fines that improve the taste a TON. This thing is a complete game changer. I love my Aeropress more now than when I first got it. Cleaning: It rinses out very easily. Not sure who is having trouble with that. The easiest way is to pull the plunger halfway back before you take the cap off so it pulls the big clump of wet grounds off the filter/cap assembly, then you remove and shake the filter/cap assembly over the trash once or twice and plunge the coffee grounds from the body of the press into the trash. Leave the plunger fully inserted into the body and rinse both the combined cap/filter assembly (don’t remove the filter) and the combined plunger/body assembly (plunger end only) in the sink for literally 3 seconds. Shake both assemblies a half dozen times over the sink to get the majority of the water off, then put it away with the plunger fully inserted and the cap off to fully air-dry. I place my press on top of the useless funnel it came with and use it as a vertical press-holder in my cabinet. Looks like a coffee rocket ready for launch. Reported Cap Tightness: It is a little tighter than the original, but if you’re stronger than a 1-armed, 90 lb., 105 year old grandmother with advanced arthritis you won’t have any issues. Just turn it in the grooves until it’s snug, you don’t have to torque it all the way in there until you need a pipe wrench to remove it. I agree that it’s slightly tighter than the factory cap, but I honestly don’t see the problem here if you apply basic common sense. I have never had the slightest issue with this, and nether has my 130 lb. girlfriend. Summary: If you have at least grandmother strength, an IQ over 30, you’re tired of coffee leaking past your filter onto your counter, tired of risking a catastrophe every time you use the inverted method, or want the oils and fines in your brew, this is the answer. I can’t imagine going back to those stupid paper filters. This should be standard equipment.

The Prismo Attachment makes a good product a great product! I have struggled for months to make a good cup of coffee at home. My trusty Keurig went from brewing a decent cup of morning coffee to brewing undrinkable swill (and yes, I descaled and thoroughly cleaned it as directed by the manufacturer). Was it the Keurig unit? Was it the pods? I don't know. I thought a simple drip coffee maker would be the answer, but I just wasn't happy with that either, even using filtered water and freshly ground beans. And then I read about the AeroPress and decided to give it a try. After a few days experimentation I was able to produce a decent cup of coffee - decent, but not great. The original review I had read recommended the Fellow Prismo Attachment, but I hesitated because of the cost and I questioned how much difference it could really make. I just finished the first cup of coffee I made with the AeroPress with the Prismo Attachement and it was, without a doubt, the best tasting cup of coffee I have ever made at home. Is the Fellow Prismo Attachment a little pricey? Yes Is the Fellow Prismo Attachment worth the price? Also Yes

I wasn’t sure I liked my Aeropress coffee maker- it brewed too quickly and unless inverting it, the coffee doesn’t dwell long enough unless you invert the Aeropress, which feels unsafe. This replacement filter lid makes the end result taste much better. Worth every penny!

Sunday Dec 8, 2024 I got the replacement and this one does leak at all, so now I can continue with the review: a. It does what its main purpose is. Unless you press on the plunger, coffee will not leak into your cup. b. The coffee was almost 100% clear of any coffee grit, so kudos on the filter's ability to let only liquid go thru. c. The coffee had a slight metallic taste. This is expected from all metal filters. It was not overwhelming so in my opinion it did not affect the taste much at all. d. It was easy to clean. I do not know why some reviewers said it was difficult. I had no problems with it. e. The packaging is well designed. Very easy to unpack the unit (thank you "Fellow" for not requiring a chain-saw to open the package). Overall, I think this is a product that covers a gap in the Aeropress lineup. It costs almost as much as the Aeropress; that makes no sense to me. If you have extra $30 and you don't know what to do with them, go ahead. For me, I can buy lots of paper filters with $30. Friday Dec 6, 2024 I had high hopes when I received this product because I did not like the fact that the Aeropress allows coffee to leak into your glass until you create a vacuum with the plunger. If you are not fast, a lot of undesirable coffee will end up in your glass. In terms of delivering the value proposition (stop the leaking) the product failed pretty badly. Not a noticeable improvement over the paper filter. I spent my professional life in Product Development and Manufacturing. Looking at the materials used and the general design, I cannot fathom a single reason with this gadget will retail for more than $10. So, not only that it does not work as advertised, but the retail cost is not defensible. I returned mine and asked Amazon for a replacement. Maybe I got a bad one and the next one will work great ...... give them a second chance. I am surprised that Aeropress does not offer a pressure-activated filter, better designed, half the price; an easy upsell. For now, I cannot recommend this product. With $30 you can buy a lot of good paper filters.

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.

Lo compré porque me dejé llevar por tener un café con más presión y por tanto más parecido a un expreso. Me he visto muchas reviews y algunos sí lo recomiendan y otros dicen que no merece la pena. Decidí probarlo por mi mismo. La tapa cuesta un poco de encajar en la Aeropress, pero encaja bien. El filtro de metal hará que no gaste tanto en papeles para el filtro, aunque realmente el gasto es ínfimo porque los papeles se puede reutilizar muchas veces. Según tengo entendido, la "espuma" la produce el metal. Un parte muy positiva es que te permite hacer el café en la posición normal sin tener que invertir el Aeropress, ya que la válvula solo se abre si hay presión. Por lo demás, la "espuma" que genera no dura más que unos segundos, y sin ser un experto en café, diría que el café tiene el mismo sabor que el hecho de forma normal. Es un aparato interesante, y si has llegado hasta esta página para comprarlo, es porque quieres mejorar tu aeropress y terminarás comprándolo y lo utilizarás. Pero si no lo tienes, ni conoces, no lo echarás en falta. Creo que no aporta un gran valor añadido, aunque es un complemento válido.
