IMPROVE YOUR COFFEE: Paper filters are known to produce a lighter, sweeter cup of coffee compared to metal filters. Paper filters are absorbent and tightly woven to filter out most oils and microorganisms Easy to use: Simply rinse the paper with boiling water before use. Rinsing helps minimize the papery taste when you get to the end of your brew and helps the coffee filter through more easily Reduces Cafestol: Did you know that drinking five cups of unfiltered coffee every day for four weeks can increase cholesterol levels, which is thought to be due to cafestol? Significantly reduce your intake by using an effective coffee filter during your brewing process, such as paper filters COMPATIBILITY: Syphon paper filters have been specifically designed for syphon coffee makers. They are compatible with the iconic and beautiful Hario Technica TCA-2, TCA-3, TCA-5 and the upcoming NXA-5 siphon units. They require a filter adapter for use. AFTER BREWING: Hario paper filters are easy to clean. Remove the wet filter from your coffee siphon after brewing and empty the coffee into a waste container. The filter paper is single-use and completely disposable.
