Other Facts:

Coffee filters of paper are made from about 100 g/cm2 crêped paper. The crêping allows the coffee to flow freely between the filter and the filtration funnel. The raw materials (pulp) for the filter paper are coarse long fiber, often from fast growing trees. Both bleached and unbleached qualities are made.

Kinds of Filters:
There are two different shapes of holders/filters: Cone (round top gradually tapering down to the bottom) and Basket (circular holder/filter with a flat bottom). What filter shape you use depends on your coffeemaker.

In general, cone shaped holders/filters are recommended as they ensure optimal coffee saturation and extraction versus basket shaped holders/filters.

Paper versus Permanant Filters:
Although your coffeemaker may have come with a built in coffee filter, paper filters will brew the most flavourful cup.

Paper Filters:
Paper filters are the best way to brew coffee utilizing the drip method. They do the most thorough job in removing particulates and effectively trap bitter sediments for a smoother less bitter cup of coffee. In addition, paper filters allow you to use any type of grind while permanent filters require courser grinds. Finer grind coffees have a larger surface area exposed to the water so it provides a richer cup of coffee. Some permanent filters also transfer foreign taste and odour to your coffee.
