Hario FS-103 Siphon Cloth Filters — 5pc

Purpose-built cloth filters for siphon brewing
The Hario FS-103 is a 5-piece pack of cloth filters engineered for Hario siphon systems. Each filter is designed to sit correctly in the siphon filter assembly, restoring the classic siphon texture and mouthfeel so you can get consistent, repeatable results from your TCA/MCA/RCA series brewers.

Fuller body and expressive aromatics
Cloth filtration is the middle ground between paper and metal: it traps most fines while allowing natural oils to pass, producing a rounder, more viscous cup that emphasises sweetness and aroma. If you want a textured siphon brew that still pours clean (minimal grit), cloth filters deliver the character that many siphon enthusiasts prefer.

Compatibility & fit
FS-103 cloth filters are compatible with a number of Hario siphon models — including TCA-2, TCA-3, TCA-5, MCA-5 and RCA-4CP — and will work with most standard siphon filter assemblies when fitted correctly. That makes them a direct, hassle-free replacement for worn or stained filters.

Reusable, economical & low-waste
A single cloth, with proper care, can last many brews (dozens up to 50–100 uses depending on care and roast oils). Because they are washable and reusable, FS-103 filters reduce running costs and landfill waste compared with single-use paper options. For best results store the clean, wet filter in cold water in the fridge between uses to keep it fresh.

Care tips to keep them tasting neutral
Rinse immediately after each brew to flush out fines; periodically give the cloth a deep clean (hot soak or gentle coffee-safe cleaner such as a brief oxy or vinegar soak) if you notice oil build-up or off-odours. Some brewers also recommend boiling the cloth briefly every few weeks for a deep refresh. Replace the cloth when discolouration or a persistent change in flavour appears. These simple steps maximise lifespan and keep extraction predictable.
