These V60 coffee filters are made of 100% organic cotton. Unlike paper filters, cotton leaves no flavor behind on the coffee. The cotton absorbs some of the oils from the coffee, but will let the acid come through for a crisp and robust flavor. Filters should be replaced about once a year if used every day, includes 2 filters.
We’ve been happy with this filter. It brews a clean cup of coffee, and it’s so nice to cut another daily disposable out of our lives. It takes an extra minute to clean (dump the grounds in the compost or trash and rinse), but it’s not a big deal.
