Then get ez cups system, you get your own coffee, put in as much or as little you want , brew it to the size you want
With ez cup , no waste except for the used coffee grinds and paper filter
I like using the paper filter instead of stainless steel filter because it is easier to clean, with the ss filter you spend more time washing it out with allows coffee grinds into the septic field, and coffee grinds are not good for septic systems
