Coffee Filters.

Just as the name implies, the essence of coffee filters is to separate residues from brewed coffee.

As always, there are various kinds of filters for coffee makers. You may find it exhausting going over the very many types available to get one. However, to make your journey an easy one, we have put together the salient facts you need to know about these filter accessories and how to choose one easily. Enjoy!

Paper Coffee Filters.

Benefits of Coffee Filters

This coffee accessory offers many benefits for its users. Apart from filtering coffee, they also have some health benefits. Some of these benefits include:

  • Separate coffee grounds: The primary function of a filter is to keep processed beans and residues out of your coffee, either partially or fully. They help to provide you with a clean and particle-free cup of coffee. The filters made from paper take it further and remove oil from your brew. The best paper coffee filters even enhance the taste of your coffee.
  • Prevents risk of cholesterol increase: Filters help remove bean oil from your coffee. The oil is responsible for high blood cholesterol. That increases the risk of heart attacks and stroke.
  • Decreases death risk: Without filters, bean oils find their way into the coffee. That causes an increase in cholesterol in the blood. Studies have proven that people with high blood cholesterol are prone to cardiovascular issues like heart attacks. Such complications can lead to sudden death. Filters help to keep the oil out and reduce the rate of premature death.

Types of Coffee Filters

They are classified under different categories that include:

Material type

Paper coffee filters

This is the most common type of filter. They usually come in V or basket shape and are not reusable. They are inexpensive, easy to clean, readily available, and very effective in keeping your finished coffee ground free. Since they are not reusable, you keep buying them for brewing purposes. They also absorb the oil in your coffee and are used as percolator coffee filters.

Filters made with paper can either be bleached or unbleached (brown coffee filters). White or bleached coffee filters are processed with chemicals to achieve their plain color. While the brown or unbleached coffee filters do not go through as much process as their white counterparts.

Metal coffee filters

These are made from aluminum or perforated steel. When these reusable coffee filters are used, they produce finished products with the oil still intact. Unlike their paper counterpart, these ones may leave some coffee grounds in your coffee. You will find them valuable if you like thick coffees and do not mind bean residues in your brew.

Several coffee brewers have metal filters installed in them. If you own one of those but prefer your coffee thin and void of residues, lay paper filters on the metal sieves before using them.

Cleaning metal filters is easy. You have to rinse them properly after use. They are also permanent coffee filters and can last as long as three years if kept in proper condition.

Cloth coffee filters

If you like your coffee light and oil-free, this kind of filter may come in handy. These filter types absorb oil in the coffee and produce light, clear brews. They are inexpensive, and reusable if you clean them well. Cleaning them, however, requires a lot of dedication and patience because of the nature of their material. They do not last as long as metal coffee filters due to the frequent cleaning process the clothes go through.

These cloth filters also double as pour-over coffee filters.

Metal Coffee Filter.


  • Cone shaped coffee filters: They are used as filters for pour over coffee and are one of the most used shapes. Filters with cone shapes come in various sizes suited to your needs.
  • Basket coffee filters: These are shaped like cupcake wrappers. They can easily be used in most types of coffee brewers. Unlike the cone-shaped filters, they have flat bottoms and can be used in most types of coffee brewers.
  • Disc coffee filters: are round coffee filters shaped like discs with holes in between. They are designed to fit into any coffee percolator. However, they are scarce in the market presently.

Coffee filter sizes

There is a range of sizes to suit different amounts of coffee. They are usually in 1, 2, 4, and 6. Size No 1 is a single-serve coffee filter suitable for one cup of coffee. No 2, 4, and 6 can make about 6, 12, and 12+ cups. Generally, they can be classified into small and big coffee filters. Small coffee filters can cater to one to six users. The large coffee filters normally come in size four; they can take up to 12 cups of coffee. And you can use the extra-large coffee filters for 12 coffee cups upward.

Cloth Coffee Filter.

What to Look For in Coffee Filters

  • Material: The material could be metal, paper, or cloth. Filters made from paper and cloth keep bean oil out of the coffee while the metal coffee filter leaves some oil and grounds in the coffee, making them suitable for people who like full-bodied coffee.
  • Size: How do you want your filter to serve you? Some people use the filters in commercial brewers, which means they use the large or extra-large size. Pick a suitable size of filter that suits your need perfectly.
  • Durability: The paper types are not reusable. They are disposed of immediately after use. While the metal and cloth counterparts are reusable and can last for over one year. The metal filters are the most durable of them all. They last when you take care of them.
  • Coffee filter shape: Some filters cannot be used in some types of coffee brewers. Ensure that yours can fit into your brewer before buying.
