If you want one strong, forgiving cup in about two minutes, buy the AeroPress. If you brew for two or more and prefer a light, clean, tea-like cup, buy the Chemex. Both use paper filters, both cost under £60 in the UK, and neither needs electricity.

The real difference is what each one does to the coffee. The AeroPress steeps the grounds and then pushes the brew through a filter, which gives a fuller, rounder cup, while the Chemex is a slow pour-over that gives clarity and brightness instead.
This guide compares them on price, taste, speed, capacity, cleaning and running costs, so you can pick the one that suits your kitchen.

How Each Brewer Works
The AeroPress
Alan Adler invented the AeroPress in 2005. It is a plastic chamber and plunger. You add coffee and hot water, stir, let it steep briefly, then press the brew through a paper micro-filter into your mug.
Because you control the grind, the steep time and the amount of water, it is a flexible brewer. A single press makes roughly 240 to 270 ml of fairly concentrated coffee, which you can drink as it is or top up with hot water. The Original comes with a scoop, a stirrer and a starter pack of filters.
There are other versions if the Original does not fit. The AeroPress Go (about £40) is smaller at 210 to 240 ml and packs into its own travel mug. The Clear (about £54) uses tougher, glass-like Tritan plastic, and the XL (about £57) brews around 500 ml at once.
The Chemex
Dr Peter Schlumbohm created the Chemex in 1941. It is an hourglass-shaped glass carafe with a wooden collar and a leather tie, and it is as much a piece of kitchen design as a brewer. You fold a thick bonded paper filter into the top, pour hot water over the grounds, and the coffee drips into the carafe below.
Chemex sizes are measured in “cups” of about 5 oz, which are far smaller than a mug. The 6 cup holds around 890 ml and the 8 cup around 1.2 litres. Filters are not included, and the smallest 1 to 3 cup models take a different filter from the larger ones, so check before you order.
Taste: Body vs Clarity
Both brewers use paper, so neither gives you the sediment of a French press. The difference is in how the water meets the coffee. In the AeroPress the grounds sit in the water for a minute or so before you press, which tends to produce more body and a rounder, sweeter cup.
The Chemex filter is noticeably thicker than most pour-over papers. It slows the water down and holds back more of the oils and fine particles, so the coffee comes out cleaner and brighter with a lighter body. As a general rule, that clarity suits lighter roasts and single-origin beans, where you want to taste the fruit and the acidity.
The AeroPress is more forgiving across roast levels, which makes it a good choice if your usual bag is a medium or dark roast. These are common starting points for each, and you should adjust them to your beans:
- AeroPress: about 15 g of medium-fine coffee, 200 ml of water at 85 to 92°C, steep for 1 to 1.5 minutes, then press slowly.
- Chemex: about 30 g of medium-coarse coffee to 480 ml of water at 92 to 96°C, with a short bloom first. The whole brew takes around 4 to 5 minutes.
Grind size matters more with the Chemex than you might expect. Too fine and the thick filter clogs and the brew drags, so you want a grinder that holds a steady coarse setting, like the ones covered in our guide to the best coffee grinder for French press.
Ease of Use and Speed
The AeroPress is the easier of the two to get right. It brews in one to two minutes, it does not care much about your pouring technique, and the worst outcome is usually a cup that is a little too strong, which you fix with hot water. The main decision is whether to use the standard or inverted method, and our AeroPress tips and tricks post covers both.
The Chemex asks for a bit more attention. You pour in slow circles, wait for the drawdown, and need a kettle you can pour from steadily, though a gooseneck is not essential if you pour slowly. The payoff is a brew time of four to six minutes that doubles as a small morning ritual.
Capacity: One Mug or the Whole Table
The AeroPress makes one mug at a time. If you are brewing for two, you press twice, which is fine on a quiet morning and tiresome with guests.
The 6 cup Chemex makes enough for two or three mugs in a single brew, and you can serve straight from the carafe. If you only ever make one mug, the Chemex is hard to justify on capacity alone. If you like the idea of pour-over coffee but want it on autopilot, our best automatic pour-over coffee maker guide covers the hands-off alternative.
Cleaning and Durability
Cleaning the AeroPress takes seconds. Twist off the cap, push the plunger and the compressed puck of grounds drops into the bin, then rinse the parts. The plastic body survives drops, and the maker sells replacements for each component.
The Chemex needs a little more care. The glass carafe is dishwasher safe according to one UK retailer listing, but it is still glass, and the wooden collar needs hand washing, so check the maker’s care instructions. It is the more fragile brewer, and the one you would not pack in a rucksack.
What They Cost to Run
The purchase price is only half the story, because the filters are where the two diverge. A 350-pack of AeroPress micro-filters costs about £9.99, which works out at under 3p a brew. Chemex bonded filters cost about £12 for a box of 100, so roughly 12p a brew.
If you make one pot a day, that is about £10 a year in AeroPress filters against about £44 in Chemex filters. AeroPress paper can also be rinsed and reused several times, which brings its cost down further. Add the purchase price and, after a year of daily brewing, the AeroPress setup is roughly £50 cheaper in total.
Who Should Buy Which
Choose the AeroPress if you
Drink one mug at a time, want coffee in a couple of minutes, or like to experiment with recipes. It also wins if you want one brewer for the kitchen and the campsite, or you simply want the cheaper option to start with. Experimenting works best if you write down what you changed, and the brewing log inside our Coffee Planner is made for that.
Choose the Chemex if you
Regularly brew for two or more and like a light, clean cup that shows off good beans. It suits people who enjoy a slower, more deliberate routine, and who want something that looks good on the counter. If you are building a home coffee bar, the carafe sits well alongside the accessories in our Brewforge collection.
What About French Press, V60 and Moka Pot?
If the Chemex appeals but you are weighing it against other methods, our French press vs pour over comparison explains the trade-offs. A V60 is a cheaper cone-shaped pour-over that gives a similar clean cup with a smaller footprint. A moka pot makes strong stovetop coffee, but it is a different style again and not a true espresso.
AeroPress vs Chemex FAQ
Is the AeroPress or the Chemex better for beginners?
The AeroPress. It forgives mistakes with grind size and timing, and the cup is easy to correct with a splash of hot water. The Chemex rewards practice but gives less margin for error.
Which makes stronger coffee?
The AeroPress. It produces a concentrated brew in a small volume that you can dilute to taste. The Chemex makes a larger, lighter cup by design.
Can I use the same coffee in both?
Yes, but grind it differently. Use a medium-fine grind for the AeroPress and a medium-coarse grind for the Chemex, then adjust to taste.
Do I need a gooseneck kettle for a Chemex?
You do not need one, but it makes a slow, steady pour much easier. Without one, pour carefully and in small amounts. The AeroPress does not need one at all.
Is the AeroPress Go worth buying over the Original?
Only if you travel with it often. The Go costs a little more at about £40 and holds slightly less, at 210 to 240 ml, but it packs into its own mug. For home use the Original is the better value.
Which is cheaper to run?
The AeroPress. Its filters cost under 3p each, against about 12p for a Chemex filter, and AeroPress paper can be reused several times.
The Verdict
For most one-person households, the AeroPress is the better buy. It costs less, brews faster, is harder to get wrong and is almost impossible to break. The Chemex is the better buy if you regularly make coffee for two or more and prefer a light, clean cup over a rich one.
If you are still undecided, start with the AeroPress and see how you get on. Our guide to the best AeroPress coffee maker compares the versions in more detail. You can always add a Chemex later when you start brewing for company.
