Can You Use V60 Filters in a Chemex? (Honest Answer + Workarounds)

Table of Contents

Quick Answer: No — V60 filters don’t fit properly in a Chemex. V60 filters are cone-shaped and smaller; Chemex filters are thicker, larger, and either bonded square or pre-folded circular. Using a V60 filter in a Chemex will either collapse into the brewer or leave gaps that let grounds slip through. The workarounds are limited; if you brew Chemex regularly, buy the right filters.

I tried this myself on a Sunday morning when I’d run out of Chemex filters and only had V60 filters in the cupboard. The short answer is: you can technically pour water through both, but the result is not Chemex coffee.

Here’s exactly why they don’t swap, what you can try if you’re in a pinch, and when it’s time to just get the right gear. If pour-over is new to you, see how to make pour-over coffee first.

The Size Difference Explained

Hario V60 filters and Chemex filters look superficially similar — both are paper, both are cone-ish — but they’re engineered very differently.

V60 filters:

Designed for the V60 cone — a 60-degree angle, smaller diameter. (See best pour-over coffee maker for compatible setups.)
Thinner paper (around 0.2 mm).
Available in sizes 01, 02, and 03.
Cone-shaped with a flat fold along one seam.

Chemex filters:

Designed for the Chemex’s wider, more open cone (about 70-degree angle on most models).
Significantly thicker paper (around 0.3–0.4 mm) — about 20–30% denser than V60.
Come in two shapes: pre-folded squares (FS-100) or pre-folded circles (FC-100).
Larger overall diameter when unfolded.

The Chemex’s design depends on that thick paper. Drop a V60 filter in and you’ll see it either collapse against the glass walls or leave a gap at the top where water flows around the paper instead of through it.

For the deeper comparison between the two brewers, my Chemex vs V60 guide walks through the brewing differences in detail.

Why Filter Type Affects Taste

Paper thickness changes flow rate. Flow rate changes extraction. Extraction changes flavor. Here’s the chain:

Thicker paper (Chemex) slows water flow. This creates a longer contact time between water and grounds, producing a fuller-bodied cup with sharper clarity. Chemex filters also absorb more lipids, giving the famously clean, tea-like character.
Thinner paper (V60) flows faster. The V60 relies on grind size (a quality manual coffee grinder matters more here) and pour technique to control extraction. The result is brighter, more aromatic, slightly less filtered in body.

Use a V60 filter in a Chemex and you get the worst of both: a fast flow rate in a brewer designed for slow flow, plus oils passing through that should have been filtered. The cup tastes weak, with grit and a flat finish (full diagnostic in why is my coffee bitter).

I once made a comparison side-by-side. Same beans, same grind, same water. Chemex with V60 filter was visibly cloudier and tasted under-extracted compared to the same brew with a proper Chemex filter.

Workarounds and Hacks (When You’re Desperate)

You’ve got V60 filters and no Chemex filters. The grocery store is closed. What can you actually do?

Option 1: Double up the V60 filter. Stacking two V60 filters approximates Chemex thickness. The fit is still wrong — the filter is too small for the Chemex top — but you get closer flow rate behavior. Press the filter against the walls to seal as much as possible. Expect a thinner cup and possibly some grit.

Option 2: Brew V60 style in the Chemex. Skip trying to fake a Chemex brew. Use a V60-style pour profile: 1:16 ratio, medium grind, 45-second bloom, slow concentric pours (a gooseneck kettle makes those pours possible). Accept that you’re making something closer to V60 coffee in a Chemex-shaped vessel.

Option 3: Use a basket-style filter from a drip machine. A #4 cone drip filter is closer in size to Chemex and works in a pinch. Not great, but better than V60 paper in this specific case.

Option 4: Skip the paper, use a reusable filter. If you have a reusable metal or cloth filter that fits the Chemex, use it. You’ll get a different style (more body, some sediment) but a brewable cup. My best reusable coffee filters guide covers options that fit various brewers.

Honest take: all of these are compromises. The cup you get is “drinkable,” not “good Chemex coffee.” For a method that better tolerates filter substitutions, see drip coffee vs pour-over.

Reusable Alternatives Worth Owning

If you bounce between V60 and Chemex (I do), a reusable filter for each brewer pays for itself fast. Two are worth knowing about:

Able Kone for Chemex — a stainless steel filter sized specifically for Chemex. Produces a heavier, oilier cup than paper but eliminates the supply problem.
Cloth filters for Chemex — closer to the paper experience in body but require careful cleaning and replacement every few months.

For V60 itself, mesh and gold-plated cone filters are well-established. Worth noting: switching filter type changes the cup. Reusable filters let through more oils, producing a richer (some would say muddier) result.

I keep paper filters for both brewers as my default and use the reusables when I’m out of paper or want a different style.

V60 vs Chemex Filters

Can you use V60 filters in a Chemex? The short version:

Filter	Fits Chemex?	Workaround
V60 cone	No (too small)	Fold to fit, not ideal
Chemex bonded	Yes	use the right one
Flat-bottom	No	wrong shape

When to Just Get a V60 Instead

If you find yourself constantly running out of Chemex filters or wishing the brew were faster and brighter, a V60 might be the better daily brewer. They’re cheaper, smaller, easier to travel with, and filter supply is everywhere.

The Hario V60 ceramic dripper is around $25. Pair it with a basic gooseneck kettle and you’ve got a complete pour-over setup for less than half the price of a Chemex.

That said, the Chemex has its own appeal. The Chemex 6-cup brews more coffee at once, looks great on a counter, and the famously clean cup it produces is genuinely different. If you brew for two or more people, Chemex wins on volume.

My general advice: if you brew solo, get a V60. If you brew for a household, get a Chemex. For the full setup walk-through, my best pour-over coffee maker guide and how to make pour-over coffee cover the technique side.

What I’d Actually Do

If you’re out of Chemex filters, my honest move:

Order more Chemex filters online — they’re cheap and ship fast.
In the meantime, brew French press, AeroPress, or drip if you have them.
If you must use the Chemex today, double up V60 filters and accept the compromised result.

Don’t ruin good beans trying to force a swap. The filter is doing real work in a Chemex brew — substituting the wrong one undoes most of what makes Chemex worth using.

FAQ

Are V60 filters and Chemex filters interchangeable?
No. V60 filters are smaller and thinner, designed for a different cone angle. They won’t seal properly in a Chemex and produce a noticeably worse cup.

What size Chemex filter do I need?
For the standard 6-cup and 8-cup Chemex, use the FS-100 (pre-folded square) or FC-100 (circular) filters. For the smaller 3-cup, use the FP-2 size.

Can I use coffee filters from a drip machine in a Chemex?
Cone-shaped #4 drip filters can work in a pinch but are thinner than Chemex filters and produce a different cup. They’re a better emergency substitute than V60 filters.

Why are Chemex filters so much thicker?
The thicker paper slows water flow and filters out more lipids and micro-particles. This is what produces the famously clean, tea-like body Chemex is known for. Thinner filters can’t replicate it.
