Dripper set HARIO V60-03 Immersion Switch with filters — pour-over coffee brewer, size 03

HARIO V60-03 Immersion Switch with filters is a pour-over coffee dripper set designed for manual brewing of 2–4 cups. The device combines immersion-style steeping with a V60-style control of flow, allowing users to manage extraction time and water contact for consistent results. The set ships with matching paper filters sized for the 03 dripper and is intended for home use, small cafés, or anyone seeking reproducible manual brewing performance.

Advantages

The Immersion Switch design enables controlled immersion followed by a filtered drawdown, which helps to balance body and clarity in the cup without advanced equipment. The V60 cone geometry and internal ridges promote even water distribution and prevent channeling, while the switch mechanism lets you pause and resume flow for repeatable extraction curves. Supplied paper filters simplify cleanup and maintain consistent filtration characteristics across brews.

Suitable for

• Brewing 2–4 cups of pour-over coffee at home
• Small cafés or office coffee stations requiring manual control
• Users learning extraction variables such as immersion time and drawdown
• Preparation of single-origin or filter roast coffees where clarity and body need balancing

Key specifications

• Capacity: suitable for preparing 2–4 cups (size 03)
• Design: cone-shaped dripper combining immersion chamber and V60-style flow control
• Included accessories: paper filters sized for the 03 dripper
• Material: heat-resistant, food-safe materials designed for hot-water brewing
• Compatibility: compatible with standard 03-size paper filters and typical pour-over servers or carafes

How to use

Place a paper filter in the HARIO V60-03 Immersion Switch and rinse with hot water to remove paper taste and preheat the dripper and server. Add ground coffee of the appropriate grind for immersion-style pour-over, start a timed bloom by pouring a small amount of water, then close the switch to allow the coffee to steep for the chosen immersion time. After steeping, open the switch to initiate drawdown, pouring additional water as needed to reach the desired yield. Adjust grind size, coffee dose, water temperature, and immersion time to dial in extraction for your preferred balance of body and clarity.

Usage recommendations

For consistent results, use a scale and timer, rinse filters before brewing, and experiment with a 1:15–1:17 coffee-to-water ratio as a starting point. When targeting clarity, shorten immersion time or grind slightly finer; for greater body, extend immersion time or grind coarser. Clean the switch mechanism after use to prevent residue buildup and keep flow consistent.
