Coffee filters are an essential part of the coffee-making process, helping to separate the coffee grounds from the brewed coffee. They come in various types, materials, and sizes, each with its own unique characteristics that can impact the taste and quality of your coffee. Understanding the different types of coffee filters and their uses will help you choose the best option for your brewing method and personal preferences.
