Prismo AeroPress Filter Cap for Espresso-Style Coffee & Cold Brew | No-Drip Seal, Pressure Actuated Valve, Reusable Stainless Steel Mesh, No Inversion Needed, No Paper Filters, Full Immersion

This Fellow Prismo filter/flow control cap combo is a great alternative to the AeroPress Flow Control. Here's why; The flow control cap and the stainless steel micro filter come together for a cost savings. The cap doesn't leak when I'm pushing the plunger to extract the coffee, which sometimes happens with the AeroPress. And it performs just as well, keeping the hot water and coffee grounds in the cylinder until I'm ready to push the plunger. My coffee tastes just as great as when I use the AeroPress product. No down side, this is my daily use flow control cap now. Note for paper filter users; The stainless steel micro filter is imbedded in the gasket that creates the seal between the cap and the AeroPress body. Would that affect the fit of a paper filter? I don't know. I don't use paper filters, but if I can dig some up I'll test it out.

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!

I purchased the Prismo filter with attachment to use with my AeroPress, to make sure that the coffee stays put once I pour hot water in/stir, until I’m ready to extract using the plunger attachment. I think it goes without saying that owning an AeroPress means I’d like the best tasting coffee I can make at home, and the Prismo attachment helps elevate the AeroPress. With the attachment that came with the AeroPress, a portion of the coffee would end up in the cup right away since it had multiple holes at the bottom (so, after pouring water to line 4, the coffee would reach around line 3 before I’d use the plunger attachment to extract.) It still tasted good, but with a coffee press, you’d think the coffee should have more time to brew beforehand. I originally purchased the alternate AeroPress attachment that has the same function as the Prismo, minus the stainless steel filter, and even after washing, putting it on the top rack of the dishwasher, and even submerging it in warm water with baking soda for at least an hour each time, and then using the paper filter, I’d end up with a chemical perfume taste that leached into the coffee from the plastic, making me unable to drink anything past a sip. After making a few cups of coffee to try to get the scent to dissipate, I realized I’d have to return it (maybe I received a defective product.) Anyhow, I decided to purchase the Prismo attachment plus metal filter instead, based on reviews, and it does not disappoint. I have used it with just the metal filter and it works fine, but my preferred way is to put the metal filter first, then a paper filter on top of it, just to help make clean up easier. It works great either way, and allows for a very rich, flavorful cup of coffee. I use water heated to 194 degrees on a temperature controlled electric kettle—if you don’t have one, I’d recommend using water that hasn’t quite reached boiling point, or boiling water and allowing it to sit for a few minutes first. This way, coffee ends up with a smoother flavor. If you’re a coffee enthusiast, looking for a way to make even AeroPress coffee taste better than it already does, this is for you!

4 stars rather than 5 for a few simple reasons: 1) it seems overpriced at $25 for what it is, 2) all of the marketing for this is wrong. You will not get crema. It will have no affect on the coffee at all. I don't even see why they would think there would be. The pressure needed to get through the valve is less than it takes to press the coffee through a metal filter. In fact, it's harder for me to press through an ABLE ultra fine disk than the Prismo. I bought this because I found the inverted method to be annoying to set up and I finally had the disaster where the Aeropress opens up during the flip and spills coffee all over your entire kitchen. If $25 means that will never happen again, then I'm sold. This does make the full-immersion brewing with the Aeropress a thousand times better (and safer). It's also much easier to have the Aeropress on a scale during pouring. Cleaning was a concern of mine. It's easy to clean but nowhere as easy than just a disk filter. Since the filter remains inside the cap after you remove it, grounds tend to stick to it and you have to remove them by hand - whereas a disc filter can just slide right off cleanly. Another big plus is that it does not drip after you take the Aeropress off the mug. And while pressing, nothing shoots off to the sides. My main concern is durability. I'm worried the valve will break off or start to wear. I've only had it for a few weeks so I'l have to wait and see how it holds up over time.

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.

I bought this after knocking over the AeroPress a couple of time using the inverted method. The mess is just what you would imagine with grounds and coffee everywhere. I used the inverted methods because I like to stir longer to help maximize the extraction without most of the coffee dripping out as it does when putting the AeroPress in the upright position. This attachment gives me the best of both methods and I highly recommend it. BTW, the permanent filter works well by itself with very little if any sediment ending up in the mug. However, I still use a filter paper with it because the paper absorbs most of the cafestrol, which is a saturated fat in coffee that gram for gram has been found to raise cholesterol level more than another type of saturated fat. With the amount of coffee that I drink my doctor recommended I stop using my beloved French press and move to filtered coffee (she also recommended I cut back on the amount of coffee I drink, but fat chance of that) as part of a set of other changes to my diet, namely switching to a whole food, plant based diet, to lower my cholesterol so that I could avoid having to take a statin. With such a major change in diet, it's hard to tell how much of a difference switching to filtered coffee made to the drop in my total cholesterol from 210-220 to 140 and LDL from 150 to 90. But it turns out I like the less bitter flavor with the paper filter. One note of caution, when using a paper filter you still have to use the metal microfilter with the paper filter on top. I forgot once and with only the edges of the filter gripped between the cap and the cylinder and nothing under it to support it, as soon as I started to press the filter paper pulled out and ended up as a lump in the valve cap. Coffee would only come out when the paper wasn't covering the valve, but then the grounds came out as well. And when the lump of paper covered the valve nothing would come out. Oh, and one last thing, despite what Fellows might imply, the pressure during the press is far too low to make anything like the crema one gets from a high pressure espresso machine. Instead what you get is a thin jet of coffee coming out of the center valve at a good velocity. This entrains some air as it goes into the coffee already in the mug. This causes some small amount of froth. But making the AeroPress into an espresso maker isn't why I bought this, so this little bit of exaggeration doesn't bother me.

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

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.

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。

Clean

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

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.

It works well, but don’t kid yourself that you will get crema out of this 😅
