OREA - O2 Brewer

Spotted: 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.

The Darth Black edition? A special launch finish with a deep, semi‑transparent black that nods to OREA's original V3 Glossy Black – but with heavier pigmentation while still allowing a view inside the brewer. Dark, mysterious, and utterly on‑brand for anyone who appreciates the dark side of coffee.

Each brewer is moulded from a single piece of genuine Eastman Tritan plastic – BPA‑free, food‑safe, made in the USA – 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 – no moving parts

• Original OPEN bottom design for a more conical flow and central water path

• Compatible with OREA Regulators for immersion and hybrid brewing (including the Hario Switch base)

• Compatible with the Neo Negotiator (sold separately)

• Best suited to lighter, more tea‑like bodied brews – for thicker body, OREA recommends the Z1 brewers

Filter Compatibility:

• Wave: Traditional 185 wave size or OREA's large wave paper – more bypass, more airflow, less concentrated

• Flat: Large 185 OREA flat filters or large 185 Sibarist FAST flat filters (labelled O2/V4 filters) – less bypass, wider bed, juicier cup
