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. Common in the US are cone-shaped filters #2, #4, and #6, as well as basket-shaped filters in an 8-12 cup size. Other important parameters are strength, compatibility, efficiency and capacity.
The caffeine content of instant coffee is generally less than that of brewed coffee. One study comparing various home-prepared samples came to the result that regular instant coffee (not decaffeinated) has a median caffeine content of 66 mg per cup (range 29â117 mg per cup), with a median cup size of 225 ml (range 170-285 ml) and a caffeine concentration of 328 Âµg/ml (range 102-559 Âµg/ml).
