100 size unbleached / brown coffee filter papers. Suitable for domestic filter coffee machines and plastic dripper cones Easier to clean up : They can be thrown away right after use, with no clean up beyond placing the used filter in a trash can. They're strong too - even when wet : This ensures a steady drip of coffee through the filter, so it brews at just the right rate for a great taste. Removes cholesterol raising oils : Only paper filters eliminate oil with diterpene found in coffee.
