FAQ:

Q: What are the uses of coffee filters?

A: Other Uses for Filters. “Real Simple” suggests using clean paper coffee filters to clean windows and mirrors for a lint-free finish, and as spacers between fine china to prevent scratches. You can also poke a hole through a coffee filter and slide it onto a popsicle stick or ice-cream cone to prevent messy drips.

Q: How big is a coffee filter?

A: Typically coffee filters are made up of filaments approximately 20 micrometres wide, which allow particles through that are less than approximately 10 to 15 micrometres. For a filter to be compatible with a coffee maker, the filter needs to be a specific shape and size.

Q: What material is a coffee filter made of?

A: Coffee filters of paper are made from about 100 g/m2 filter paper. The crimping of the sides allows the coffee to flow freely between the filter and the filtration funnel. The raw materials (pulp) for the filter paper are coarse long fiber, often from fast growing trees.
