The thickest filter paper in coffee, which strips out oils and fines and leaves a cup like tea. Divisive by design — you will either love the clarity or find it hollow.
The bottom line The cleanest cup in manual brewing, and the least forgiving of the wrong beans.
The Chemex has been in production essentially unchanged since 1941, and its defining feature is not the shape. It is the paper.
Chemex filters are twenty to thirty per cent thicker than a standard filter paper, and that thickness does two things. It traps the coffee oils that give a cup its body and mouthfeel, and it holds back the fine particles that make a brew taste muddy or bitter at the finish. What comes through is remarkably clean — closer to a good tea than to what most people picture as coffee.
Whether that is what you want depends entirely on the beans. A washed Kenyan or a floral Ethiopian, brewed in a Chemex, is a genuinely different experience: the acidity is bright and separated, the finish is clean, and nothing muddles. Put a dark Italian roast through the same paper and you strip out exactly what made it worth drinking, leaving something thin.
Two practical difficulties. Because the paper is so restrictive, the grind must be coarser than for a V60 — the commonest complaint about slow Chemex brews is a grind that would have worked fine in a cone. And the neck is narrower than an adult hand, so washing it means a bottle brush and patience.
Buy the filters when you buy the brewer, and buy more than you think. Running out of Chemex papers on a Sunday morning is a specific kind of annoyance, because nothing else in the cupboard substitutes properly.
What we like, and what we don't
Strengths
Exceptional clarity — no sediment, no oils, no muddiness at all
Brews and serves in one vessel; it looks like an object, not an appliance
One piece of glass, so there is nothing to wear out
Compromises
Proprietary filters that are thick, expensive and easy to run out of
Slow brew, and it chokes if the grind is even slightly too fine
Awkward to wash; the neck is narrower than your hand

Questions people actually ask
Why are Chemex filters so expensive, and can I substitute?
They are 20 to 30 per cent thicker than standard filter papers, which is the entire point — that thickness is what removes the oils and fine particles. Substituting a thin V60 paper works mechanically and gives you a different, less clean cup. If clarity is why you bought a Chemex, the filters are not the place to save money.
Chemex or V60?
Same family, opposite ends. The V60 lets more oil and body through and brews faster; the Chemex strips them out and takes longer. A fruity Kenyan sings through a Chemex. A chocolatey Brazilian can taste thin and hollow in one.
Why does mine drain so slowly?
Grind, almost always. The thick paper is already restrictive, so a grind that works in a V60 will choke a Chemex. Go a step or two coarser than you think, and make sure the folded paper's triple layer sits over the pouring spout channel.

The one brewer that makes a good cup while you are still learning. Immersion means time does the work instead of your pour — so a mediocre grinder and an ordinary kettle still produce something you want to drink.
Best for: Your first real brewer, an office drawer, or anywhere a V60 would be a nuisance.
Steep like a French press, drain through paper like a pour-over, and the valve opens by itself when you set it on the cup. The most forgiving route to a genuinely clean brew.
Best for: Anyone who wants V60 clarity without owning a gooseneck kettle.
