From Texas in the United States, we introduce a coffee filter made of organic cotton that can be washed and used over and over again. In order to live a simpler life, we propose a coffee time that places as little burden on the global environment as possible! It's very simple to use. Instead of a paper filter, use a cotton filter from CoffeeSock and just brew your coffee! * When using for the first time, be sure to boil for about 10 minutes before use. It's easy to clean, and after use, all you have to do is remove the coffee grounds, rinse it with water, and dry it. No detergent required! Unlike flannel filters, there is no need to soak them in water and store them. However, the oil and dregs of the coffee will gradually stick, making it difficult for the coffee to fall off. Be sure to boil once every 6~8 weeks. If you take proper care of it, you can use it repeatedly for about 1 year (about 500 times) per sheet. It is true that it may take more time than using a paper filter. However, the amount of garbage generated has decreased from the daily healing coffee time, If it becomes a little earth-friendly, you will be able to spend an even more beautiful time with coffee. Why don't you make earth-friendly choices from a familiar place? ――――――――――― Recommended for people like this! ――――――――――― ☑ Those who enjoy coffee on a daily basis You can enjoy coffee that is a little different from the paper filter. Cotton absorbs the oil released by the coffee beans moderately, but allows the acid to pass through moderately. The result is a well-balanced coffee that is clear, refreshing, rich and powerful, without the distractions of paper filters. ☑ Those who are interested in eco-friendliness, sustainability, and environmental issues By using CoffeeSock filters, you can greatly reduce paper filter waste. When you're done drinking, be sure to put the coffee grounds in the compost! When the filter itself has completed its mission, it can be chopped into small pieces and returned to the soil. Materials and production areas are also linked to efforts to reduce global waste and combat climate change. ☑ As a gift for your loved ones It is easy to clean, and the extracted coffee is deepened and delicious.
