HARIO F-103S paper coffee filters are round cone disposable filters designed for pour-over brewing. Made to fit manual drippers that accept this size, these filters separate ground coffee from the brewed liquid, producing a clean cup with reduced sediment and oils. The single-use format provides hygienic, convenient filtration for home, office, or travel, and supports consistent extraction when used with appropriate grind and pouring technique.
Advantages
These paper filters offer fine filtration that reduces suspended particles and natural coffee oils, resulting in a clearer cup and a brighter flavour profile. Their conical shape promotes even water flow through the coffee bed, helping maintain extraction consistency. Being disposable, they eliminate the need for cleaning and reduce cross-contamination between brews, while lightweight packaging makes them easy to store and carry.
Suitable for
- Home pour-over brewing with compatible round cone drippers
- Office or workplace coffee preparation where quick, hygienic service is needed
- Travel, camping, or short trips where disposable filtration is preferred
- Brewers and users seeking a cleaner cup with less sediment and oils

How to use
Place a filter into a compatible round cone dripper, rinse briefly with hot water if desired to remove paper taste and preheat the dripper, then discard the rinse water. Add the measured ground coffee, pour hot water in a controlled circular motion to bloom and continue pouring according to your preferred recipe. After brewing, lift the dripper and dispose of the used filter with grounds. Follow standard safety precautions when handling hot water and avoid burns.
Usage recommendations
Use medium-fine to medium grind for balanced extraction, pre-wet the filter for improved flow and flavour clarity, and store filters in a dry place away from strong odours to preserve neutral paper characteristics. Adjust dose and pour rate to match your dripper and coffee for optimal results.
