The Hario V60 filter papers have been designed to remove unnecessary oils from your brew. The Hario Filter paper range is available in 3 different sizes, allowing you to match the filter size to the Hario V60 dripper that you are using. The filters are natural, so it is always recommended to pre-wet/ rinse the papers prior to use to ensure that no paper taste is transferred during the brewing process. The Hario V60 filter papers are biodegradable and will consistently deliver a perfectly clean, sediment free brew.
