Chemex Pre-Folded Natural Filter Squares (FSU-100)

These unbleached, pre-folded square filter papers are the perfect companion for your Chemex coffeemaker. Designed to deliver a pure, smooth cup, they feature a cone shape that promotes uniform extraction and a thicker specialty fibre (20–30% thicker than standard filters) to trap oils and finer grounds - leaving only the most delicious flavours to flow through to your brew.

Sustainable Brewing with Chemex
Chemex isn’t just about exceptional coffee - it’s a conscious choice for environmentally mindful brewing. Its minimalist design reduces reliance on plastic and metal components, while the thick, natural paper filters are fully compostable and biodegradable, helping to minimise waste. Chemex brewers are built to last, encouraging long-term use over disposable alternatives. Paired with sustainably sourced filters like the FSU-100, Chemex supports a low-impact coffee ritual that aligns with eco-friendly values without compromising on flavour.
