The swappable screens allow you to experiment with different levels of filtration and flow resistance. You can swap them out to fine-tune how much sediment passes through or to alter the overall drawdown speed of your brew.
Yes, the dripper is designed to work with standard 155 flat or wave-style filters. It comes with 100 wave filter papers to get you started.
If you choose the black valve option, you can use the subtle laser markings to track your settings. This makes it much easier to replicate your favorite flow rate and extraction profile for future brews.
