O2 Brewer - CLEAR

O2 Brewer – Clear
The bigger sibling that actually delivers on its promises.

The O2 is OREA's answer to those who brew for more than just themselves, whether that's a generous single serve or brewing for two. It shares the O1's original open bottom design, letting the paper filter bend naturally through the middle for a more central water flow and a candy-like acidity, with balance, sweetness, and body intact. Because more volume shouldn't mean less precision.

Each brewer is moulded from a single piece of genuine Eastman Tritan plastic. It's BPA-free, food-safe, made in the USA, and manufactured by a family-run boutique factory in Taiwan. No moving parts, no injection marks, no flow marks. Just a clean, simple, easy-to-clean design.

Features

• Unibody single-piece construction with no moving parts
• Original open bottom for a more conical flow and central water path
• Compatible with OREA Regulators for immersion and hybrid brewing, including the Hario Switch base
• Best suited to lighter, more tea-like brews. For a thicker body, try the Z1.

Filters

• Wave: traditional 185 wave size or OREA's large wave paper. More bypass and airflow, less concentrated.
• Flat: large 185 OREA flat filters or large 185 Sibarist FAST flat filters (labelled O2/V4). Less bypass, wider bed, juicier cup.
