A:AnswerNot sure it's necessary....I do use filters because I use an expresso grind. It stops most of the grinds from getting in the final brew. The filters are Aerobie Aeropress replacement filters sold by Barista Press on Amazon. If you're using a regular grind I would say not to bother with the filters.
A:Answeryou cannot. you'd have to cut open the kcup top and then pour the coffee into the basket. it does not have any mechanism to pierce the kcup. beware this coffee maker caused stomach pains/upset/illness every time i consumed it's brewed coffee. probably the black plastic water reservoir leaking BPA into coffee or mold/bacteria stuck in internal reservoir that can't be cleaned/reached. beware. :(
A:AnswerIf by "cup" you mean the travel mug then no, it's not included.
The model has a measuring cup you scoop the ground coffee into with a mesh bottom that filters the coffee as it is brewing (if that is what "cup" you are referring to then yes, 1 scoop is included. Another older model included 2 scoop cups but not this newer model).
