Coffee filter paper can more evenly and fully soak the extracted coffee essence, thus obtaining a purer coffee taste, so filter paper is very popular in our life.
In the market, there are bleached filter paper vs unbleached filter paper, and coffee filter paper is mostly made of wood. The color of the pulp after wood steaming is mostly brown, and it needs to go through several bleaching processes to become white.
Bleached filter paper vs unbleached filter paper: Are unbleached coffee filters better?
1. Bleached filter paper: Bleached filter paper undergoes multiple bleaching processes to make it white. This treatment method now mostly uses oxidation bleaching (also known as acid bleaching) rather than traditional chlorination bleaching. This bleaching process has greatly reduced the impact on the environment and is safe for human health. The advantage of bleached filter paper is that it has less paper smell and will not affect the taste of coffee. Some well-known coffee filter paper brands use advanced enzyme bleaching. This bleaching method is widely used in the medical field, so it can be considered safe and will not add other odors.
2. Unbleached filter paper: Unbleached filter paper presents the light brown color of the wood of the pulp raw material itself, which is more natural. When using log filter paper, a small amount of wood smell may enter the coffee, affecting the flavor of the coffee. However, if the log filter paper is fully moistened with hot water before use, the odor can be greatly reduced.
Selection suggestion: If you care about the environmental impact and do not want the coffee taste to be affected by the taste of the filter paper itself, bleached coffee filter paper is a better choice.
If you prefer a more natural coffee flavor and don't mind the extra preparation steps (such as thoroughly wetting the wood filter with hot water), the Unbleached coffee filter paper may be more suitable for you.
In general, both filter paper can be used. The key is what you expect the coffee flavor to be and whether you are willing to do the extra preparation to maintain the natural flavor.
Difference between bleached filter paper and unbleached filter paper:
1. Environmental Protection Compared to the two, bleached paper coffee filters are bad for the environment.
Because bleaching is added to the manufacturing process, even if only a small amount of bleach is used, these paper filters with bleach will still pollute the environment when discarded.
Oxygen bleached filters are relatively environmentally friendly compared to chlorine bleached filters. Chlorine can damage the soil.
2. Flavor There is also a lot of controversy about whether bleached and unbleached paper coffee filters have an effect on the flavor of coffee.
For ordinary everyday coffee drinkers, the difference may be small, while experienced coffee lovers may find that unbleached paper coffee filters have a slight paper taste.
However, unbleached paper coffee filters are generally rinsed when used. If you rinse the filter before brewing coffee, it can be almost completely removed.
So neither type of paper coffee filter will have a big impact on the flavor of coffee, but the thickness of the paper will.
3. Quality When choosing a filter, make sure you not only choose the right size for your chosen brewing method, but also the right thickness.
Filters with thinner paper can allow water to flow through too quickly, which may negatively affect your brew and make it taste bad; the thicker the filter, the more expensive it will be and the better the coffee flavor will be.

The factor to choose Coffee filter paper:
1. Consideration of removing the pulp taste In fact, the bleached and unbleached filter paper introduced above, the original pulp filter paper has not been rinsed, and the wood pulp taste is still very strong, so the filter paper needs to be washed. For bleached filter paper, the residual paper taste and bleaching taste vary depending on the brand. High-quality filter paper can indeed be processed very cleanly, and there is not much difference between washing and not washing.
2. Consideration of fit with the filter cup Rinsing the filter paper helps to improve the fit of the filter paper to the filter cup, and helps to fit the rib design of the filter cup and the brewing principle. However, in most cases, the fit between the filter paper and the filter cup is worse than that of preheating and pre-rinsing when brewing without washing the filter paper.
3. Considerations of filter paper absorbing coffee oil and initial extraction liquid If the filter paper is not rinsed during brewing, the filter paper will absorb some water and oil during steaming, and bring out some suspicious flavors.
