V60 01 vs 02: Choose by Your Batch, Filters and Cup Size

The short answer: 01 for a smaller batch, 02 for more headroom

Start with your usual recipe rather than the number on the box. HARIO lists its V60 size 01 for 1 to 2 cups and the V60 size 02 for 1 to 4 cups. If your regular brew is a small single mug, the 01 keeps the equipment compact. If your recipes regularly stretch beyond that, or you want one dripper that can also brew a larger batch, the 02 adds room and is still a legitimate option for one-serving recipes.

Neither size guarantees a particular flavor. The choice changes your working room, the paper that fits, and how much water you can comfortably pour, not the quality of the beans or the recipe.

What the matched HARIO USA specifications say

The figures below describe the clear plastic models HARIO sells in the United States, checked on 18 October 2026: the V60 Plastic Coffee Dripper 01 and the V60 Plastic Coffee Dripper 02. Both pages list acrylonitrile-styrene resin and showed a displayed price of $13 USD.

Displayed prices exclude delivery and tax and are not availability guarantees. The variant selectors were unavailable in the static capture used for this check, so treat the table as a dated record of what the pages showed, not a live stock report.

Cup counts are labels, not US mug volumes

The cup figure is HARIO's serving label. It is not a US 8-ounce mug measure, and it is not a guarantee of finished beverage volume. What reaches your mug depends on your dose, your poured water, how much the grounds retain, and how you serve the brew.

So the label cannot tell you whether your favorite mug will be filled. It tells you which size band the manufacturer places the dripper in, which narrows the choice without predicting a final volume.

Match the paper to the dripper

Filter fit decides whether a size is practical day to day. Our recommendation is to match 01 papers with the 01 dripper and 02 papers with the 02 dripper, using the exact pack that names your size. HARIO's filter listing is easy to misread: the URL for the 02 paper filter still says "for 01 drippers", while the page title and product numbers identify the 02 filter, listed at 1 to 4 cups. Check the pack and the product number, not the web address.

The two sizes share the V60's conical shape, spiral ribs and single large hole, as described on HARIO Europe's V60 page. That shared design is not proof of a safe or equivalent cross-size fit. Listing 01 and 02 papers as separate products also does not prove that every cross-size use is impossible; it simply leaves the exact named size as the default. Use the size printed on your dripper and on the filter pack, and do not assume that an improvised fold or a forced fit will behave like the correctly sized paper.

A choosing workflow you can finish in one sitting

1. Note your usual coffee dose in grams.
2. Note the recipe's input water in grams.
3. Measure the finished amount you want in your usual mug.
4. Record the dripper, its material, and the paper pack that matches it.
5. Confirm safe fit and headroom: the paper should sit properly and your intended water level should stay below the paper rim.
6. If you already own an 02, try it with an appropriate smaller recipe before buying an 01 just for taste.

An 02 running a smaller recipe is not automatically the same as an 01, because the paper and the dripper size differ. It is still the cheaper way to learn whether your current setup covers the job before you buy a second brewer.

Water in, coffee out

Recipe water is an input, not a promise of finished coffee. Wet grounds hold onto water, and there is no universal retention factor you can subtract across coffees, grind settings and drippers. A 250-gram pour therefore does not reliably land as 250 grams in the cup.

Weigh the grounds you actually dose rather than assuming that what goes into the hopper equals what reaches the brewer. Grinder retention is its own variable, and it changes the mass balance you are trying to read.

If you compare the two sizes yourself

If you want your own comparison, change one size only where the paper and recipe can be held meaningfully similar. A different paper is a confounder: it changes flow and contact even when the dose stays the same. Log more than one brew per setup, because a single cup cannot establish cause and effect. Note the filter difference instead of attributing every change to the dripper.
