Ever struggle with slow, clogged filters while brewing pour-over?

Traditional paper filters get saturated with fines and oils, slowing drawdown times and leading to bitter, astringent flavors. Grinding coarser helps—but at the cost of full flavor extraction?! A breakthrough in filter technology is changing how we brew for the better. 

Jiyoon co-developed these plant-based filters with Kasley at Pure.F to maintain a steady flow rate from start to finish. That means more clarity, more control, and no over-extraction—perfect for everything from high-end, delicate coffees to approachable dark-roast brews.

Super fast

These filters are interesting, I’ve never used filters made out of the same material. They are super thin and almost feel like parchment paper. Incredibly fast flowing, if that is what you are looking for. A couple downsides though. The material is very stiff, so if you plan on using these for an origami or folding them for a UFO, it won’t work, they spring back to their original shape. This material also lets a fair bit of the finest particles through. Because you have to grind so fine to get these to draw down in a reasonable time, the fines kind of muddy the cup a bit.
