Do you struggle with the inverted method? You may have the fear of spilling it everywhere and I don’t blame you. It’s not very safe.

If you’ve struggled at all with the inverted method, this method’s for you. Why not give your AeroPress superpowers using a little-known attachment for the AeroPress?

Introducing the Fellow Prismo.

Features of the Fellow Prismo

One feature of the Prismo, is that you can make amazing full-immersion coffee without using the inverted method. Learn all about the Fellow Prismo and why you should own it here.

If you want to get a delicious crema with the Prismo, you’ll need to use an ultra-fine grind. This helps to build up pressure when pressing the coffee through the Prismo metal filter. This also helps to produce a crema.

Instructions

Here’s the step-by-step method:

  1. Insert the metal filter into your Fellow Prismo.
  2. Screw the Prismo onto your AeroPress chamber.
  3. Pour 1 scoop of ultra-fine grind into your AeroPress chamber.
  4. Pour 50mls of boiling water into your AeroPress chamber.
  5. Stir your coffee for 20 seconds.
  6. Leave your coffee to steep for 1 minute.
  7. Place your AeroPress onto your coffee cup.
  8. Insert your plunger into the AeroPress chamber.
  9. Press HARD until you reach the coffee grounds.
  10. Be amazed at the crema you have produced!
  11. Drink as is, or add hot milk and sugar to taste.
  12. Enjoy your coffee!

Now you’re familiar with the incredible Fellow Prismo and the basic recipe. Fantastic! Next, let’s look at the Maximum Crema method.

What Grind for AeroPress Prismo Maximum Crema Method?

What Grind for AeroPress PuckPuck Method?

Cold brew is delicious and one of the best ways to enjoy coffee. The only thing is that it takes several hours to brew, which isn’t always practical.

Have you often found yourself wishing it would brew faster? Have you experienced remembering that you meant to make some cold brew the day before but forgot?

Luckily for you, there’s the PuckPuck! The PuckPuck is an innovative AeroPress cold brew attachment that makes slow-drip cold brew coffee. But in about 3 ½ hours. Super fast!

For brewing with the PuckPuck, you’ll need a medium grind.

Instructions

Let’s take a look at the step-by-step process:

  1. Place a paper filter into your AeroPress filter cap and screw it onto the AeroPress chamber.
  2. Sit your AeroPress on a jug or suitable container. It needs to be large enough to hold at least 400ml.
  3. Pour 38g of medium grind into your AeroPress chamber, then give a gentle shake or a tap to level the grounds.
  4. Gently drop your PuckPuck splash filter into your AeroPress chamber. Make sure it’s sitting flat on top of the grounds.
  5. Attach your PuckPuck water vessel onto the PuckPuck. Place the PuckPuck onto your AeroPress. If you didn’t buy the water vessel with the PuckPuck, you can use a compatible water bottle instead.
  6. Place your PuckPuck and water vessel onto your AeroPress chamber.
  7. Pour 100g of ice into your PuckPuck water vessel. Pour 400ml of water into your PuckPuck water vessel.
  8. Slowly adjust the drip rate of your PuckPuck to about 50 drips per minute. Do this by holding the bottom section of the PuckPuck and turning the top section anti-clockwise. This can be a bit tricky to get the hang of, but you’ll get it. Start very slow until you see drips coming out of your PuckPuck.
  9. Check your PuckPuck from time to time, making sure the drip rate isn’t speeding up or slowing down.
  10. Wait until all the water has dripped through the water vessel. Remove the AeroPress and PuckPuck combo from your jug or container and place in your kitchen sink for cleaning.
  11. Pour some of your delicious cold brew into a large glass or mug with ice.
  12. Add sugar or milk to taste.
  13. Enjoy your delicious cold brew coffee!

If you’d rather make the guaranteed and reliable coffee that the AeroPress instructions recommend, take a look at this next method.

What Grind for AeroPress Standard Method?

top view of aeropress with water added and stirring with spoon

This is the proven method that you started with when you first got your AeroPress. It’s the standard method that you’re provided in the AeroPress instructions. For this method, you’ll want to use a fine grind.

This is because brewing with this method has a minimal brewing time. If you were to use a coarser grind, you wouldn’t extract enough of the goodness.

Instructions

The step-by-step method is:

  1. Insert a paper filter into your AeroPress cap.
  2. Screw your AeroPress cap onto the AeroPress chamber.
  3. Place your AeroPress onto your cup. Pour in one scoop of your fine grind coffee into the AeroPress chamber.
  4. Pour hot water into the AeroPress chamber up to the number 1 on the chamber.
  5. Using the included stirring paddle, stir the coffee for about 10 seconds.
  6. Insert your AeroPress plunger into the chamber and lightly press, until all the coffee is in your cup.
  7. Add milk or sugar to taste.
  8. Enjoy your coffee!

Now we’ve covered the standard method, let’s take a look at a different popular method.

What Grind for AeroPress Inverted Method?

The inverted method is a popular brewing method with the AeroPress. Brewing with this method makes a full-immersion brew, which you can leave to steep as long as you like.

Think of it as more like a french press brew.

I should warn you though, this method is not recommended by Aerobie. It does have the potential to leak or spill if not done correctly, so be careful!

Unlike the standard method above, you’ll want a fine-to-medium grind for this method. If you use a too fine grind, it could lead to over-extraction because of the longer steeping time.

The setup for this method is a little different, too. Insert the AeroPress plunger into the chamber up to the number 4. Now turn the AeroPress upside down and use the AeroPress plunger as a stand for the AeroPress.

The AeroPress is now ready to add your fine-to-medium grind and hot water.

Instructions

Let’s take a look at the step-by-step instructions:

  1. Insert your AeroPress plunger into the AeroPress chamber up to the number 4.
  2. Turn your AeroPress upside-down, using the AeroPress plunger as a stand.
  3. Pour in one scoop of fine-to-medium grind into the AeroPress chamber.
  4. Pour 50mls of hot water into your AeroPress chamber and stir for 20 seconds.
  5. Leave your coffee to steep for 30 seconds.
  6. Pour hot water to the top of your AeroPress and then leave for a further 60 seconds.
  7. Place a paper filter into your AeroPress cap and wet the filter so it sticks to the cap.
  8. Screw the cap onto the AeroPress chamber.
  9. Turn your coffee cup upside-down and place it on top of the AeroPress.
  10. Holding both your cup and the AeroPress, turn them both the right-side up in one smooth motion.
  11. Gently press your AeroPress plunger into the chamber until all the coffee is in your cup.
  12. Add milk or sugar to taste.
  13. Enjoy your coffee!

So how did you go with that one? I’m sure you nailed it without any struggle!

Conclusion

So there you have 5 different grinds for 5 different AeroPress methods. Now you’re armed with some powerful info to get out there and make the best brew that you can!!

Have you got another AeroPress brewing method to suggest? Have you tried one of these methods and not achieved the results you were hoping for?

Best AeroPress Accessories for Brewing

Fellow Prismo


The Fellow Prismo is made by Fellow Industries. With the Prismo, you can make a full-immersion espresso-style brew without needing to use the inverted method.

It replaces the standard filter cap that comes with the AeroPress with a cap that has a pressure-actuated valve.

This stops the flow of coffee from the AeroPress until you apply pressure, giving you greater control. It also comes with a 150 micron reusable metal filter.

Because it creates an air-tight seal, you can also use it to make AeroPress cold brew overnight.

It also creates mind-blowing crema (if you use the right secret method). Learn more about that here.

See price on Amazon

PuckPuck


If you ever wanted to be able to make quick cold brew with your AeroPress, meet the PuckPuck.

The PuckPuck is a puck sized AeroPress cold brew attachment that sits on top of your AeroPress chamber. It drips ice-cold water into your AeroPress from an attached water vessel.

It enables the AeroPress to produce Kyoto style slow-drip cold brew coffee in about 2.5 – 3 hours time. That’s quick!

You can buy it with or without the PuckPuck water vessel, as it has the capability of using a compatible water bottle instead. See their website for a list of compatible bottles.

See price on Amazon

Aesir Paper Filters

Huh? Doesn’t the AeroPress come with its own paper filters? Yes, but Aesir paper filters are different.

The Aesir Paper Filters are premium filters made from high quality paper. They are twice as thick as the standard AeroPress paper filters.

Having smaller pores means that you transfer more vibrance, clarity and juiciness to your cup. They also reduce the sediment.

They’re low absorbent, so you won’t lose any of the natural coffee oils, either.

There must be a reason why several World AeroPress Champions use these paper filters.

See price on Amazon

Able Disk Filter

If you want the option of a reusable metal filter instead of paper filters, you should check out the Able Disk Filter. There’s two different types of Able Disk Filters available.

The standard stainless steel filter produces a fuller-bodied cup. This is because some of the coffee fines are able to pass into your cup when you press.

The fine filter option allows less coffee fines to enter your cup. So, it produces a lighter, cleaner cup of coffee.

Be aware that the fine filter is thinner than the standard filter, so it’s possible to bend if you apply too much pressure.

They’re made 100% in the USA and used by AeroPress professionals. Able also sponsored the World AeroPress Championships in 2019.

See price on Amazon

Porlex Mini Coffee Grinder


The Porlex Mini Coffee Grinder is a ceramic burr hand grinder that compliments the features of the AeroPress well. It’s

  • portable,
  • durable,
  • fast,
  • lightweight, and
  • compact.

If you travel with your AeroPress and need a coffee grinder that can travel with you, definitely consider the Porlex Mini.

It’s perfect for travelling with the AeroPress, as due to its small size, it can fit inside the AeroPress itself.

Not only that, it also produces a good grind and is made in Japan.

See price on Amazon

2Pour


The 2Pour is an AeroPress accessory that saves you time by pressing your coffee into two cups at once.

This means you don’t need to:

  • switch cups half-way,
  • press it all into one large cup or jug and then transfer it to your drinking cups, or
  • make two separate brews all together.

The concept is easy enough. Place two coffee cups under the 2Pour spouts, place your AeroPress on top of the 2Pour and then press.

Make sure you have some smaller coffee cups than a standard mug in the house, as the 2Pour isn’t that tall.

See price on Amazon

Best AeroPress Accessories for Traveling

JavaJug / JavaJug 2


The JavaJug (or JavaJug 2) is a stainless steel jug for pressing your AeroPress coffee into. It’s also great for storing your AeroPress.

You may find that when travelling it can be difficult to find a cup that your AeroPress can fit.

It’s wide enough to fit the AeroPress cap so you can press your coffee without spilling a drop. If you’re making many cups, you can serve from the JavaJug.

You can also follow the markings on the inside that show how much hot water to add before serving.

It comes with a JavaJacket that wraps around the JavaJug to insulate it and keep it either cool or hot. The JavaJacket is available in six different colours.

When you’re all done making coffee, remove the filter cap and place it in the JavaJug. Then, put in your AeroPress upside down.

Push the AeroPress plunger all the way through the chamber, so it doesn’t compress the plunger gasket. If left compressed, your AeroPress gasket can wear out faster.

See price on Amazon

Able travel cap


Planning to bring some coffee beans with you to grind fresh while you travel? Unless you’ve got loads of storage, you’ll enjoy using the Able Travel Cap.

It’s a cap that fits on the open end of the AeroPress plunger. This lets you use the empty space inside the plunger as a storage compartment.

This is perfect for storing some coffee beans or even some filter papers. Although it doesn’t hold heaps of beans, it may be enough until you can buy some more while you travel.

It also provides better stability for the AeroPress when you’re brewing using the inverted method. Finally, it’s made in the USA.

See price on Amazon

Eagle Creek Pack It Tube Cube


When you travel, having a travel case makes sure that all your parts and pieces stay together.

This avoids anything getting damaged in your luggage. It also helps you locate your parts and pieces much faster.

The Eagle Creek Pack It Tube Cube is a travel case that will fit everything you need to keep you brewing fresh coffee.

The zip is accessible on both ends, meaning easy access to either side of the case.

It’s also backed by a lifetime “no matter what” warranty! That’s pretty amazing.

See price on Amazon

Ondamota Herb Container


You can use the Ondamota Herb Container to store your ground coffee. It makes a perfect little accessory for travelling with your AeroPress.

It’s 2.1 inches high, 1 inch wide, so small enough to fit in your pocket. It’s made from lightweight, durable aluminium and comes in a variety of colors.

When sealed, it’s air-tight and locks in the freshness and aroma of your ground coffee.

See price on Amazon

Best AeroPress Accessories for Storage

Hexnub Organizer


Everything needs a home. If that’s true for you, whether you’re at home or the office, you’ll enjoy owning a Hexnub Organizer for your AeroPress.

It looks great wherever you are and has space for all your AeroPress parts, including:

  • the chamber,
  • the plunger,
  • the scoop,
  • the stirring paddle,
  • the funnel, and
  • the filter papers (with holder)

You can also store your coffee mugs on top of it, with the top shelf including a heat-proof silicone rubber drip mat.

You should also be happy to hear that it’s made from 100% recyclable bamboo, so environmentally friendly, too.

If you have even less space and need something more compact, Hexnub also offer a compact version of the Hexnub Organizer.

See price on Amazon

Blue Horse Caddy


Don’t leave your AeroPress anywhere. You can now organize your countertop with the help of the Blue Horse Caddy.

It holds your AeroPress and all the parts with a place for everything. It even allows you to have somewhere to dry your AeroPress after use.

The Blue Horse Caddy:

  • is made from stainless steel,
  • is durable, and
  • has non-slip rubber feet, which keep the caddy secure and also protect whatever surface you use it on.

If that wasn’t enough, it’s also made in the USA, so expect good quality.

How To Travel With An AeroPress Like A Pro

If you’re getting ready for a trip but find yourself wondering how to travel with an AeroPress, you’re not alone.

One of the things that was immediately obvious when I first saw my friend’s AeroPress, was its portability. I could see the huge benefit in owning a coffee maker that you could bring with you pretty much anywhere.

My friend spoke about just that. He would bring it with him when he went camping, when he visited his parents, when he went to the office and when he went for cycling trips.

It was one of the things he loved the most about it, aside from making great coffee. Since owning my own, it’s also become one of the things that I love the most about it, too.

If you want to travel with an AeroPress, you could purchase an AeroPress travel kit or case, or the AeroPress Go which neatly packs away into a travel mug which you press your coffee into, or even the JavaJug.

There’s many options and there’s no right or wrong way of doing it. As with most things, it comes down to what your needs are.

Before you rush off to buy your travel setup, there’s a few factors to consider that will help determine which option will suit you best:

  • What items you need to bring
  • How much space you have
  • How much weight you can carry
  • How long your trip is

Let’s take a closer look at each of these factors.

How to Travel With an AeroPress – Factors You Should Consider

Useful items

Your travel situation will greatly impact what you need to bring with you. Here’s a list of items that may be useful for you when you travel with your AeroPress:

You’re not going to need all of these things every single time you travel with your AeroPress, but some of them will help you greatly.

If you’re just visiting your parents locally, for instance, the AeroPress, a suitable hand grinder and a travel cap for storing beans would be enough.

You could even make it simpler by grinding the beans before you go and bringing them in a herb pot. I’m sure you get the idea here.

One of the options for how to travel with an AeroPress, a container with some ground coffee inside with a plastic scoop.

Storage space

If you’re traveling in a way that restricts how much storage space you have, take a minute to think about what you really need to bring with you and why.

If you’re only going for a day or two, you might be better off bringing pre-ground coffee. If anything, you’ll appreciate your freshly ground coffee that much more when you return.

When storage is a real deal-breaker, you should seriously consider getting an AeroPress Go.

If you’ve already got an AeroPress, I don’t need to convince you about the benefits, such as it’s:

  • Compact,
  • Durable,
  • Fast,
  • Portable, and
  • Lightweight

Obviously, the AeroPress Go is all these things and more. It comes complete with its very own travel mug that you can press your coffee directly into, so that’s one less thing you need to bring.

Not only that, but it’s even more compact, as it can be packed away entirely into the travel mug, drastically decreasing the amount of storage space needed.

But if that doesn’t persuade you and you already own an AeroPress, you could instead look at the option of grabbing a JavaJug.

It’s a big coffee jug that you can press your AeroPress coffee into and also store your AeroPress inside of when you’re all done.

It’s not as compact as the AeroPress Go, but if you don’t need to be that compact, it’s a suitable option.

Another option is a travel kit. There’s plenty of kits available, each with a different style and size.

Think carefully about exactly how you plan to use it, making sure it can accommodate your AeroPress and other essentials.

Weight

Man sitting in an airport departure area with feet up resting on his luggage, looking out the window at a departing aeroplane.If you’re traveling internationally, the weight of individual items in your luggage can begin to really add up. The last thing you need is another heavy item to add to your list.

AeroPress to the rescue! As I stated earlier, being lightweight is one of the key benefits of the AeroPress. You should have no hesitation about bringing it with you overseas whatsoever.

You’ll want to use some sort of travel kit to avoid your coffee gear getting damaged or moving around in transit.

And if you’re going on more of a backpacking adventure, the AeroPress Go would be a clear winner here, taking up the least amount of space, but also providing a travel mug.

You should also have your own coffee hand grinder that compliments the AeroPress, as no pre-ground coffee will last a long trip. To find out which hand grinder is most suitable, see my recent article.

Length of trip

Every trip you take is different. Are you going for several days or longer? If so, will you need to bring a grinder that matches the benefits of the AeroPress?

If the freshness of ground coffee is less important to you, can you instead pre-grind your beans before you go and bring them in a compact storage container?

For some people, they can sacrifice their desire for freshly ground coffee in exchange for the extra space they will have. For others, it’s not an option.

If you really can’t go without freshly ground coffee, you can maximise the space you have by bringing a hand grinder that can fit inside your AeroPress.

You could also use a travel cap that seals over the end of the plunger tube to hold your coffee beans.

It won’t hold enough for a long trip, but it’s something. Perhaps it’s enough to keep you going until you can purchase some more coffee beans on your travels.

Conclusion

I hope you’ve got a clearer idea about what you may or may not need to bring with you when you travel and that I’ve provided some insight about how to travel with an AeroPress.

Have you tried out any of my suggestions? How did they work for you? Do you have something to recommend that I missed? Let me know in the comments below.

A Genuine Fellow Prismo Review – AeroPress Attachment

Disclosure: Some of these links are affiliate links. At no extra cost, I earn a commission if you buy from them, which helps to maintain this website.

Do you like using the inverted method with your AeroPress, but have that little voice in the back of your mind? The one that says “watch out, it might spill everywhere!”

Unfortunately, sometimes it does happen. Imagine having to clean up your kitchen when it does… coffee everywhere!

Do you also enjoy espresso coffee, but can’t take your espresso machine with you everywhere you go?

In that case, the Prismo is the life-changing answer you’ve been looking for.

Not only does the Fellow Prismo make espresso-style coffee. It also brews full-immersion coffee in the regular position. No more inverted AeroPress!

After reading this surprising Fellow Prismo review, you will change the way you use your AeroPress forever.

Keep reading.

Fellow Prismo Review – pressure-actuated attachment for AeroPress

After searching for different attachments for the AeroPress coffee maker, I found the Prismo. It’s made by a company called Fellow Industries.

Fellow Industries is a San Francisco based company started in 2015 by Jake Miller. They make various coffee related products, with the Prismo being one of them.

The Prismo was first introduced to the world in late 2017. Since then, it’s been gaining popularity with AeroPress users everywhere.

Let’s take a closer look at it.

The Fellow Prismo, which helps to get crema from an AeroPress
Click this image to view this on Amazon.

What is the Fellow Prismo and how does it work?

Why not let Fellow show you exactly what the Prismo is in this short video.

The Fellow Prismo is a pressure-actuated attachment for the AeroPress. It makes full immersion espresso-style coffee, without needing to use the inverted method.

But what is full immersion coffee?

What is full immersion coffee?

Full immersion coffee is a method of brewing coffee. It’s any brewing method where coffee and water mix together in a container for a period of time.

Once the coffee is ready, it’s filtered from the brewing device into your cup.

The most common device that uses full immersion is the coffee plunger or french press. But there are loads of different devices that use this brewing method.

Some other examples are siphons and cold brew makers. Even Fellow Industries made a device called the Duo Coffee Steeper, which has now been discontinued.

The Prismo converts your AeroPress into a full immersion brewer, without using the unstable inverted method.

So, it’s a:

  • custom AeroPress cap with a no drip seal,
  • pressure actuated valve, and
  • a reusable metal filter.

If you’re wondering “what’s a pressure-actuated valve?”, I’ll break it down.

Pressure-actuated Valve

The valve is the small bit of rubber with a cross incision on it that sits in the center of the custom cap.

Pressure-actuated means that it’s pressure that puts the valve into action and pushes it open.

Before pressing your brew, the valve is in the closed position, which stops the flow of your brew into your cup.

Applying pressure on the AeroPress plunger opens the valve immediately. This pushes the brew into your cup like a jet stream.

The result is an immersion brew, without using the inverted method.

This is different from the standard AeroPress cap, which drips into your cup when you add hot water. Brewing with the Fellow Prismo or inverted method avoids this.

But unlike the inverted method, the Prismo has no risk of accidental spills.

What comes with the Fellow Prismo for AeroPress?

Fellow Prismo cap

The custom cap has a pressure-actuated valve. It screws onto the bottom of the AeroPress chamber instead of the original cap.

The pressure actuated valve stays sealed until you press down. This holds your brew in the AeroPress chamber.

Combined with a “no drip seal”, you can brew a full immersion coffee without inverting your AeroPress.

Reusable metal filter

Compared to some of the metal filters that you can find for the AeroPress, this one is great quality. Although, it does have a bit of flex, so you’d want to be gentle with it.

It has a silicon cover around the edge of the filter which is not removable. I have noticed that it can get a little bit difficult to clean around the edges of the cover.

Close up of the Fellow Prismo 150 micron etched fine metal filter.

Each hole in the filter is… how many microns?

How many microns?

For starters, what’s a micron, you ask? A micron, also known as a micrometer, is a unit of length that is one thousandth of a millimetre.

I wasn’t sure of the exact specs of the filter, as I’d read multiple variations.

This page says the filter is an “80 micron” etched metal filter. Whereas this page says the filter is “150 micron”. And this page says the filter is “70 micron”.

So which is it? Well, I decided to go straight to the source and contacted Fellow Industries to find out.

Here’s my email.

My email to Fellow Industries that states "Hi, I'm an AeroPress user and I recently purchased the Prismo. I'm very happy with my purchase, though I'm still getting the hang of it and experimenting a bit. I was wondering if you could clarify something for me. On the product page of your website, it states that the filter is "150 microns" - https://fellowproducts.com/products/prismo/ - whereas on one of your earlier blog posts, it states that the filter is "80 microns" - https://fellowproducts.com/blogs/brew-guides/prismo-superpowers-for-your-aeropress%C2%AE - and then on Amazon.com it states that the filter is "70 microns" - https://www.amazon.com/Fellow-Pressure-Actuated-Attachment-AeroPress-Espresso-Style/dp/B079YBT2LJ/. I realise that the filter has probably changed over time. Can you please confirm which filter you are currently distributing? Kind regards, Marty"

 

And here’s their super-prompt response, received in less than 24 hours!

An email reply from Fellow Industries that states "Thanks for reaching out, Marty! We need to update those pages as the Prismo filter is 150 microns now (this change was made a few years ago). Let me know if I can clarify anything or answer other questions you may have! Best, Nick"

So there you have it. Thanks to Nick from Fellow Industries, we now know the correct specs for the current filter. It’s 150 microns.

So that means that each little hole in the metal filter is 0.15 of a millimetre. That is tiny!

I was also pleased with Nick’s prompt response. They took the time to respond to their customer’s queries. It shows that their customers are important.

That’s an A+ right there.

How do you use the Fellow Prismo?

It’s very easy to begin using the Fellow Prismo. Standard instructions are:

  1. Place the reusable metal filter inside the cap, with the Fellow text on the filter face-up.
  2. Screw the cap onto the AeroPress chamber. Make sure that the Fellow logo icon on the cap aligns with the numbers on the AeroPress chamber.
  3. Measure 20g of ultra-fine ground coffee and pour into the AeroPress chamber.
  4. Place the AeroPress onto your coffee cup or glass.
  5. Pour 50ml of boiling water (100˚C/212˚F) into the AeroPress chamber.
  6. Stir the coffee for 20 seconds.
  7. Let the coffee sit for one minute.
  8. Place the AeroPress plunger into the chamber. Give an initial quick, hard press to compress the coffee grounds. Maintain constant pressure until the plunger reaches the bottom.
  9. Remove the Prismo from the AeroPress and wash all parts.
  10. Drink and enjoy your espresso-style coffee.

This is the standard Fellow Prismo instructions and should produce a crema.

Watch this video to learn a simple technique that will boost your AeroPress crema to extreme! Read this post to learn more.

If you’re interested, you can also use the Prismo to make cold brew.

Cleaning the Fellow Prismo

Clean the Fellow Prismo after every use. This will stop it getting clogged up by coffee oils and impacting your brew.

Don’t use anything abrasive or rough though, only a soft sponge. It’s also safe to put it in the top rack of your dishwasher.

Another option is to clean it with warm soapy water. To clean it this way, all you need to do is:

  1. Take everything apart and rinse it after use.
  2. Attach the Prismo with filter back onto the AeroPress chamber.
  3. Add some warm soapy water into the AeroPress chamber.
  4. Press and pull the soapy water through the Prismo.
  5. Rinse any soapy residue off the parts.

You could fill the AeroPress chamber with plain warm water and press it through the Prismo once more.

This also would help to remove any soapy residue from all the parts.

Can you use the Fellow Prismo with a paper filter?

Sure. You can use a paper filter with the Prismo, but I don’t know why you’d want to. After all, it’s designed for you to use it with a metal filter.

The people at Fellow Industries spent months doing research. They tried different options for brewing with the Prismo.

Their decision was to design, create and package their own fine metal filter. I doubt they decided to pack the Prismo with their own metal filter on a whim.

But, there are 2 secret methods of using a paper filter with the Prismo metal filter that I have tried.

One of them involves tamping the coffee inside the AeroPress and then packing a paper filter on top.

The other method is so secret, you’ll have to read the article to find out about it. It’s actually stupid-simple!

In fact, these have been the only methods that I’ve used to get anything close to a crema.

I explain this method in full amazing detail here.
