There are some cleanliness issues with this type of coffee maker apparently.,I don't know, but I don't want to buy the individual packages so I don't have one. I have become hooked on my small French press. I use one scoop of coffee grounds and it make the nice strong coffee I like. I buy Trader Joe's French roast and it is perfect. Hubby likes a milder blend, so I have their medium roast for him and we both get the single cup,concept for far less. I also went back to using a Farberware perculator for company as the coffee is much hotter. Ya know,sometimes the old way is the best way.
