Non-Woven Coffee Filter Paper: How It Works in Coffee Brewing

How Does Non-Woven Coffee Filter Paper Change Coffee Brewing?

Non-woven filter paper is made from a plastic-based material without spinning or weaving, which gives it larger gaps than wood pulp paper. During coffee brewing, those gaps let oils and fine particles pass into the cup along with the liquid, adding aroma and body, while the paper itself has a rougher feel than standard filters.

A special version of this paper looks and feels closer to wood pulp paper, smooth with a velvety touch, so it sits between the two types in character. Comparing wood pulp paper, the special non-woven paper, and regular non-woven paper with room-temperature water, hot water, and coffee liquid shows how much oils in coffee each one lets through.

Non-woven filter paper, also known as nonwoven fabric filter paper, has always attracted attention in coffee brewing for its ability to let oils and fine particles pass through and enhance body. Front Street Coffee noticed a special filter paper that differs from regular non-woven fabric in both appearance and feel—its texture is closer to wood pulp filter paper, smooth with a velvety touch. To figure out what exactly makes this filter paper so remarkable, Front Street Coffee started with the material principles, comparing the differences between wood pulp filter paper, special non-woven filter paper, and regular non-woven filter paper, and observed its performance through tests with room-temperature water, hot water, and coffee liquid. This article will comprehensively sort out the composition principles of non-woven filter paper, the definition of nonwoven fabric, and the characteristics of this special filter paper in actual use, helping coffee enthusiasts understand the differences between it and traditional filter paper.

This immediately piqued Front Street Coffee's interest, so today we're going to test this magical filter paper and see just how magical it really is!

Magical bypass-free filter paper? From the introduction on the packaging, Front Street Coffee discovered that this is a non-woven filter paper, but whether in appearance or in the texture when touched, it is vastly different from regular non-woven filter paper. We all know that non-woven filter paper is made from a special kind of plastic. Because it does not require spinning, weaving, or other such processes to be made, it also has the alias "nonwoven fabric." Since the gaps in non-woven filter paper are larger than those in regular wood pulp filter paper, besides coffee liquid, the oils and fine particles of the coffee can also pass through the filter paper, adding aroma and body to the coffee. But because of this, its texture when touched is relatively rough.

This special non-woven filter paper, however, looks closer to wood pulp filter paper, and its texture when touched is not rough—instead it is very smooth, with a slight velvety feel. For details, see the image below; from left to right, they are wood pulp filter paper, special non-woven filter paper, and regular non-woven filter paper.

So Front Street Coffee began testing, placing the filter paper into the dripper, then pouring in room-temperature water, hot water, and coffee liquid respectively.
