How Do Permanent Coffee Filters Work?
Permanent coffee filters work by allowing water to pass through the tiny pores or openings in the material while capturing coffee grounds. These filters are typically made of stainless steel or nylon mesh, which is fine enough to prevent coffee grounds from escaping but still allows water to flow through. The filter can be used repeatedly and is easy to clean, making it a more eco-friendly and cost-effective option than disposable paper filters.
