Last Updated: 2025/09/14, We are used to wetting the filter paper when making coffee. In addition to removing the taste of the paper and removing dust, the purpose of wetting is to make the filter paper conform to the filter cup.

We are used to wetting the filter paper when making coffee. In addition to removing the taste of the paper and removing dust, the purpose of wetting is to make the filter paper conform to the filter cup.

Because most filter cups are designed with outwardly protruding ribs on the inside of the wall, their main role is to support the filter paper to increase the exhaust channel during the brewing process, thereby increasing the speed at which coffee is discharged. And if we want these ribs to do their job, we need to fit the filter paper into the filter cup. The more fully the fit, the more complete the effect.

However, many friends couldn't get the filter paper to adhere to the filter cup when they first started, which greatly reduced the effect of the ribs. Therefore, friends often sigh in surprise after seeing Qianjie's filter paper that fits perfectly with the filter cup in the store, and then ask Qianjie how it did it. If this happens to you in front of the screen, it doesn't matter! Today, Qianjie will come and share some tips for making filter paper conform to the filter cup!

1. Fold the filter paper right Yes, everyone is right. The first thing Qianjie wants to share is "How to fold the filter paper well"! Because the main reason why many friends cannot make the filter paper and the filter cup fit perfectly is that the folding technique is improper, which causes the angle and shape of the filter paper to be folded out to not match the filter cup. Naturally, it is impossible to fit perfectly with the filter cup! So the first thing Qianjie needs to share is how to fold the filter paper.

Currently, there are three main types of filter cup filter papers on the market: conical filter paper, fan filter paper, and cake filter paper. Among the three, only conical filter paper and fan filter paper need to be folded, so this sharing mainly focuses on them. In fact, whether it is conical or fan-shaped, there are only three steps to folding the filter paper: ① First, fold it according to the suture line on the edge of the filter paper;② Then use two fingers to open it from inside the filter paper;③ Finally, press it gently in the open position so that it will not be easily traced back into a piece of paper. The folding of a filter paper is thus completed.

The fan filter paper works the same way, except that it cannot be folded in half, so don't press too hard at the end to keep it from easily turning back into paper.

As long as our folding is relatively standard, the resulting filter paper can perfectly fit most filter cups. Yes, just most of it! Some filter cups will have certain differences in shape from conventional filter paper due to their design. For example, Kono filter cups or ceramic filter cups cannot fit perfectly with standard folded conical filter paper. For filter cups of this type, Qianjie would advise everyone to be less standard when folding the filter paper and fold it a little more. (The left side is folded normally, and the right side is folded a little too much)

Just fold the filter paper at the bottom a little more, and the shape of the filter paper can be changed to adapt to the shape of the filter cup and achieve a perfect fit. Then what you need to know is that Qianjie is just an example. Different filter cups may have different folding methods, so you can use this as a reference to find out the different ones that fit different filter cups. Stacking method.

2. Press and hold down the filter paper during wetting. The reason why many filter papers cannot be attached to the filter cup is because the filter paper cannot contact the filter cup during the wetting process, so it cannot be attached to the filter cup. Therefore, before wetting, we can press the filter paper with our hands in advance to ensure that the filter paper can come into contact with the filter cup during the wetting process, so as to ensure a perfect fit.

The specific method is very simple! Take Qianjie as an example. After putting the filter paper into the filter cup, we use our index finger and thumb (other fingers will also work) to press on both sides of the filter paper, and gently press the filter paper until it can no longer move down, pour in water. Wet, and then you will find that the filter paper and the filter cup fit perfectly ~

Of course, you can also use your hands! At present, there are also some appliances specially used to press filter paper on the market, but the price... It's just a little touching.

3. Wet with hot water. There are still some filter papers that cannot be attached to the filter cup mainly due to their material. For example, non-woven filter papers are of high hardness, so it is difficult for normal temperature water to attach them to the filter cup.

In this case, we need to use hot water at a higher temperature to wet it and soften it at high temperature, thereby reducing the difficulty of attaching the filter paper.

So, the above are a few tips commonly used on Qianjie to make filter papers and filter cups compliant. If you have any other better ways, please leave a message in the comment area to share with you ~
