Filter Coffee Machine

The latest coffee making machines usually come attached with a grinder to enable the use of the whole and roasted coffee bean immediately before brewing the coffee. The use of the whole coffee bean just before the brewing of the coffee increases the flavor and the aroma and the general taste and experience of the coffee drinking process. But one thing that crops up here is the sediment, which is the remnant of the ground coffee bean. Though everyone loves to have their coffee bean grounded just before brewing their cup of coffee, none of us would ever want to be chewing the coffee bean sediment in our mouths. If ever such a thing would happen, it would definitely spoil the pleasure of the wonderfully brewed cup of coffee.

This is precisely what the coffee filter is supposed to deal with. Every filter coffee machine comes attached with a filter. These filters are usually found in the lower part of the coffee machine, just above the pot or the carafe which houses all the brewed coffee. The basket of the coffee making machine usually houses the filter. The filters found in the filter coffee machines can be broadly classified in to 2 categories:

Disposable

Re-usable

The disposable filters are as the name suggests meant only for single or limited use. They will require to be disposed off after the function of filtering is carried out. These are typically made of paper. The paper used in creating these filters could be either sourced from recycled paper or from non recycled paper.

The reusable filters in the filter coffee machine are usually made of 2 components:

A hard and tough plastic frame

A fine and strong metal mesh.

The filters are recognized and categorized on the basis of a specific number provided to each filter. The number usually denotes the grade of fineness of the filter. In the United States of America, the usual numbers of the filters used are 2 and 4.

The filters in the filter coffee machine are provided with numerous openings for the hot coffee mixed with the ground coffee beans to pass through them. They actually act as a strainer and strain out all the unwanted sediments out of the coffee, to allow only the filtered and strained liquid to pass down in to the pot or the receiving container of the coffee machine.
