Aesir filters are made from a premium quality, laboratory grade paper that is produced with a more consistent pulp for a more even extraction, and a smaller pore size which filters out sediment and produces more clarity than any other option, while not sacrificing body. Used by National and World Champion baristas and home enthusiasts to produce the best possible cup of coffee. 

If you are curious to learn more about the effect that paper quality has on coffee, we recommend reading this study by Coffee Ad Astra, an independent website that has done an in-depth analysis, including Aesir filters.
