REDUCES CAFESTOL: Did you know that drinking large quantities of unfiltered coffee every day could increase cholesterol levels believed to be due to Cafestol? Significantly reduce your intake by using an effective coffee filter during your brewing process, like paper filters. EASY TO USE: Simply rinse the paper with boiling water before use. Rinsing helps to minimise the paper taste as you get to the end of your brew and helps the coffee to filter through easier.
