I no longer drink coffee but I was a real snob about it when I did.
This single serving filter does not use any additional filters it has a gold mesh screen. It makes excellent coffee.

Most of the gadgets you will find at a place like REI do not make very good coffee; some make terrible brown water instead.

French presses make a pretty good cup.

Edit; It looks like to one in the link has a SS screen instead of gold.
