How to Fold Filter Paper for Pour-Over Coffee

You’ve got your pour-over dripper ready, your grinder dialled in, and freshly roasted beans on deck — but there’s one small step that trips up many home brewers: folding the filter paper. Getting it right ensures even flow, better extraction, and prevents paper taste from spoiling your cup.

Fold your filter paper in half, then in half again to form a cone. Place the folded side facing the pouring spout for stability. For most drippers like the V60 or Kalita Wave, use the classic three-panel cone fold. That’s all — no glue, no tape, just proper alignment.

Why Fold Filter Paper at All?

Folding isn’t just about looks. It creates the right shape to fit snugly inside your dripper, directs water flow evenly, and eliminates gaps that could channel water around the grounds. Most importantly, it helps the filter sit stable during brewing — especially when pouring starts fast.

The Two Main Types of Folds

There are two common ways to fold filter paper: the classic cone fold and the flat-bottom fold. The fold you choose depends on your dripper shape.

1. Cone Fold (for V60, Bee House, etc.)

This is the most common. The paper is designed to form a tall, narrow cone — ideal for cone-shaped drippers with a single central hole.

2. Flat-Bottom Fold (for Kalita Wave, etc.)

Used for drippers with a flat base and multiple holes. The filter is folded to sit flush against the flat bottom, ensuring even water distribution.

Step-by-Step: How to Fold a Pour-Over Filter

Follow these steps for the standard cone filter used in most hand-brew setups. These directions match what you’ll find in most pour-over guides and work for drippers like the V60, Melitta, and Bee House.

Step 1: Start with the Unfolded Filter

Pick up your paper filter. Most pour-over filters are pre-folded into a quarter shape. Leave it unfolded for now.

Step 2: Fold the Filter in Half

Fold the filter paper in half, bringing two opposite edges together. Crease firmly. You now have a half-circle shape.

Step 3: Fold It in Half Again

Fold the half-circle in half once more, bringing the open edges together. You’ll now have a triangular or cone-shaped piece of paper with a layered edge.

Step 4: Identify the Folded Side

Look at the folded edge — this is the side that will face the dripper’s spout. It adds stability and prevents the filter from tipping during pouring.

Step 5: Open Into a Cone

Open the filter into a three-panel cone. The single folded edge should be at the back, against the dripper wall. The open side faces upward, ready for coffee grounds.

Place the filter inside your dripper, lining it up with the brewer’s shape. For drippers like the V60 or Kalita Wave, make sure the folded edge sits against the side with the pouring spout or drainage area.

Flat-Bottom Dripper Tip

If you’re using a Kalita Wave or similar flat-bottom dripper, look for filters designed with three panels. These often come pre-folded into a shape that fits flush against the dripper’s flat base. You’ll still fold in half twice, but aim to align the layers so the filter sits level.

Do You Need to Rinse the Filter?

Yes. After folding, always rinse your filter with hot water before brewing. This removes any paper taste and preheats your brewer and cup. Discard the rinse water before adding coffee.

Common Mistakes to Avoid

• Folding the wrong way: Placing the open seam toward the spout can cause instability or uneven flow.
• Not opening the filter fully: A collapsed cone restricts water flow and leads to over-extraction.
• Ignoring the rinse: Skipping the rinse leaves a papery taste and affects temperature stability.

Here’s what a properly folded filter looks like when opened into a cone:
