Great question! The filter uses nano-scale pores that act as a selective barrier. Larger bitter compounds get blocked, while the smaller molecules responsible for acidity, sweetness, and aroma pass through freely. Think of it as a flavor gatekeeper. Combined with the anti-bypass design that forces all water through the coffee bed evenly, you get a noticeably cleaner and more balanced cup without changing your recipe.

It depends on how much coffee you typically brew in one session. The V01 size is designed for 1-2 cup brews and fits smaller V60 drippers like the 01 size. The V02 size handles 2-4 cups and fits the larger 02 drippers. If you are unsure, check the size number stamped on your dripper. Most home baristas brewing a single mug will do well with V01, while V02 is ideal for sharing or larger servings.

Absolutely. These filters are made from food-grade polyethylene (PE) and polypropylene (PP) composite non-woven fibers. Both materials are widely used in food-contact applications and are chemically stable at brewing temperatures. They contain no bleach, no dyes, and no paper pulp. You can brew with full confidence knowing the material will not leach anything into your coffee or alter its flavor profile.

These are absolutely built for everyday use. The fast flow design and clog resistance make them perfect for your daily morning routine. Many home baristas find them even more convenient than traditional paper because there is no need to pre-rinse. With pack sizes up to 500 sheets, you can stock up and enjoy consistently clean, sweet pour-overs every single day without running out quickly.

Keeping your filters in top shape is easy. Store them in a cool, dry place away from direct sunlight and strong odors. The non-woven material does not absorb moisture the way traditional paper does, but sealing the bag between uses is still a good habit. Avoid storing them near spices or cleaning products, as the fibers can pick up ambient scents. Proper storage ensures consistent filtration performance from the first sheet to the last.
