Initially, boil new filters in fresh water to clean and shrink for 10 minutes.
Using your favourite method of brewing, add the desired amount of coffee, and brew as is customary.
After brewing, discard grounds (great for the compost), and thoroughly rinse the filter.
Hang filter to dry.
Periodically, once every 4-6 weeks boil filters in fresh water to remove accumulated coffee oils.
If the filters are soiled with perishable food at anytime, boil for at least 5 minutes to sanitize.
Why not paper filters?
2.25 Billion Cups Of Coffee Are Consumed Globally Every Day. Assuming That At Least 1/3 Of Those Cups Are Currently Made With Paper Filters In 8 Cup Batches, 750 Million Paper Filters Are Being Made And Discarded, Each And Every Day. 275 Billion Per Year. It Takes The Equivalent Of 1.5 Million Trees To Make That Many Filters Annually. In One Year The Volume Of Trash Created By The Filters Only (Not Accounting For The Grounds) Is Enough To Fill 128 Buildings The Size Of The Louvre To A Height Of 10 Feet. Each CoffeeSock® Filter Replaces 4- 12 Boxes Of Paper Filters Per Year, Plus Your Coffee Tastes Better.
