AeroPress Flow Control Filter Cap, No Drip Filter Cap for AeroPress Portable Espresso-Style Coffee Maker, Specialty Method Coffee Maker

Recommended for best Aeropress results
This cap is tiers better than the original. It allows longer coffee immersion times, almost no leakage, and better plunger control. The cap should come with the Aeropress or be part of a premium package. It’s an immediate upgrade and recommended purchase for frequent Aeropress users.Pros:* Little to no leakage; producing fuller and less astringent results.* The ability to immerse the grinds for longer without the use of the inverted method.* Plunger presses are easier and more controlled.Cons:* Requires slightly more cleaning time compared to the original cap.* Slight leaking can happen at the walls if the plunger is pressed too firmly. This can be avoided by using less force. There will not be a lot of leaking regardless.* Note: The competing Fellow Prismo cap will produce similar results with less leakage. However, it requires a special metal filter.Pro tip: This cap + 2 paper filters will produce an amazing cup of coffee!

No need to invert anymore, makes Espresso-like coffee and foam.
This review is specifically for the Aeropress flow control Filter cap.The biggest caveat is that this does not come with a metal filter like the Fellow Prismo does. Had I known that, I might have considered the third party product instead, given how competitive the prices are for what you get. However, I have heard of third party metal filters warping the aeropress in order to use it properly. I assume you get the peace of mind that this will not warp your product, by itself of when used with Aerobie’s own metal filter.Build quality feels reasonable, although it can flex if you squeeze it right. It has a nice grippy texture along the edge that makes it easy to unscrew, and plenty of surface area to grip it for installing and removing it. Compared to the filter cap that comes with the Aeropress, it’s much easier to install and remove. I don’t have any trouble gripping it even when the cap is wet, although it is much taller and wont fit inside the Aeropress Go’s case.I tested it with an off-the-shelf dark roast coffee, finely ground in my cheapo 40 dollar cuisinart grinder, and just enough 200 degree water to make the grounds stir-able, steeped for one minute and pressed with reasonable effort. It produced a nice concentrated espresso-like drink with a significantly larger layer of foam compared to similar efforts with the stock cap. The flavor seemed different too, and in a way that I liked. I understand the aeropress and similar manuals cannot produce a true espresso, but it can make a nice substitute in my opinion.Ive been brewing with this cap regularly in my Aeropress go, sometimes for espresso-like concentrates, but often larger servings as well. I typically prefer the “inverted method” (even though it doesn’t affect the coffee, its just the process I like), but this cap generally stops water from leaking out early. I can use the Aeropress as intended (reducing spills, water burns, or wasted coffee), and squeeze more water into the chamber since I’m not worrying about keeping the plunger well-seated for a flip.UPDATE: Had some leaking issues with the cap and figured it was just user error or something. I recently found out Aerobie revised the design with a rubber gasket over this issue, and they sent me the revised model at no charge when I told them I was having leaking issues. It’s still not perfect, though the revised version works MUCH better. Having used the flow control cap for a year and Aeropress coffeemakers for much longer, this is easily the best accessory for the product. I just wish the price was competitive with the Fellow Prismo kit.

huge improvement but still leaks
The normal filter holder is useless having to do the whole upside-down thing – dumb. The Fellow version of this works better and never leaks. This one can leak if you leave the coffee to sit. Otherwise this with a metal (and paper) works great. The paper filter takes out the silt that can make the coffee bitter.

Works great, makes great coffee
This cap greatly improves using the Aeropress Go. I wish they had one for the XL. I used to have the coffee begin to flow through as soon as the filter was wet. Now the coffee will stay in the Aero Press until I push the plunger. Also, the plunger moves down more easily, without ever leaking out the sides near the bottom. I highly recommend this upgrade, and it should be packaged with all new Aeropress coffee makers.

Produto de qualidade. Mas para ser sincero INÚTIL… Não vale o investimento pões não acrescenta nada ao resultado do café, mesmo porque a Aeropress é a melhor cafeteira para viagem, não necessita de mais nada. Também me arrependi de investir no filtro permanente (metal) outro dinheiro desperdiçado, o filtro de papel faz o que é necessário.

A must have for your Aeropress to not drip. I cannot imagine why this is not included in the main package
