The washable and reusable coffee filter, an alternative to go from disposable to durable. It is used in the same way as an ordinary filter. After each use, empty the coffee grounds in your compost or in the soil of your plants or possibly dry them for a future exfoliation,... Then rinse your filter with clear water to prevent the perfume of the detergents from impregnating the fabric or does not alter the taste of the coffee and leave it to dry in the open air. It will then be ready for further use.
